Loft Conversions: From Design to Final Certificate

A loft conversion can provide additional living space within an existing property, but the project also needs to be considered in relation to the Building Regulations.

Whether you are a homeowner planning a conversion or an architect preparing drawings, understanding the Building Control process can help you plan the development more effectively.

Complete Building Control Ltd (CBC) provides professional Building Control services for domestic projects, including loft conversions, renovations and structural alterations.

Why Is Building Control Important for Loft Conversions?

Building Control helps ensure that building work demonstrates compliance with the relevant requirements of the Building Regulations 2010.

Depending on the proposed work, important considerations can include:

• Structural safety
• Fire safety
• Thermal performance
• Ventilation
• Accessibility, where applicable

The precise requirements depend on the nature and complexity of the development.

CBC’s Registered Building Inspectors work with homeowners, architects, designers and contractors to consider the relevant Building Regulations requirements throughout the project.

Considering Building Regulations During the Design Stage

Before construction begins, it is useful to consider how the proposed loft conversion will address the applicable Building Regulations.

CBC works collaboratively with design teams, providing practical advice and detailed plan examination where required.

Early involvement can help identify potential issues while the design is still being developed.

For homeowners working with an architect or designer, this can provide an opportunity to consider compliance matters before construction progresses.

Building Regulations Plan Checking

Where required, CBC can undertake a detailed examination of submitted plans.

The examination considers the proposed design against the relevant Building Regulations requirements and guidance contained within the Approved Documents.

CBC works alongside the design team, providing practical feedback where issues require further consideration.

This forms part of the wider Building Control process and helps support the transition from design to construction.

Site Inspections During a Loft Conversion

Building Control does not end when construction starts.

CBC’s Registered Building Inspectors undertake the necessary site inspections at appropriate stages of the development.

The inspections required will depend on the nature and complexity of the individual project.

CBC works closely with the site team so that relevant elements of the work can be inspected at the appropriate time.

Maintaining communication with Building Control throughout construction can help avoid situations where work requiring inspection has already been covered.

If you are an existing CBC client and need to arrange an inspection, you can use the Inspection Request Form.

What Happens When the Loft Conversion Is Completed?

Once construction has been completed, the Building Control process must also be brought to a satisfactory conclusion.

CBC’s published guidance explains that the necessary completion information, certification and Compliance Declarations must be provided as applicable.

Any outstanding issues identified during inspections must also be addressed.

Following satisfactory completion and receipt of the necessary documentation, CBC can proceed with the Final Certificate process.

Frequently Asked Questions

Does CBC provide Building Control for loft conversions?

Yes. Loft conversions are among the domestic projects covered by CBC’s Building Control services.

Can CBC review loft conversion plans?

Where required, CBC can undertake detailed plan examinations and provide practical feedback to the design team.

Will my loft conversion require site inspections?

The necessary inspections depend on the nature and complexity of the project. CBC’s Registered Building Inspectors undertake inspections at appropriate stages.

What happens when the work is finished?

The necessary completion information and certification must be provided, outstanding matters addressed and the project satisfactorily completed before CBC can proceed with issuing the Final Certificate.

What Happens When Your Plans Are Reviewed?

Preparing plans for a building project involves more than deciding how the finished development will look.

The proposed design must also address the relevant requirements of the Building Regulations.

For homeowners, architects and developers, Building Regulations plan checking is an important part of the Building Control process.

Complete Building Control Ltd (CBC) provides professional Building Control services, including detailed plan examination where required.

What Is Building Regulations Plan Checking?

Plan checking involves examining submitted drawings and supporting design information against the relevant Building Regulations requirements.

CBC’s Registered Building Inspectors work with architects, designers and other members of the project team to consider how the proposed development demonstrates compliance.

The exact matters requiring examination will depend on the type and complexity of the project.

What Areas Can Be Considered During Plan Checking?

Different projects present different Building Regulations considerations.

CBC’s published Pre-Application Advice information identifies several important areas that may need consideration, including:

• Fire safety
• Thermal requirements
• Disabled access

Other matters will depend on the proposed building work and the relevant Approved Documents.

The purpose of reviewing plans is to identify issues that may need further consideration before or during the Building Control process.

Why Is Early Plan Checking Useful?

Identifying a potential compliance issue while a project is still being designed can be preferable to discovering it once construction has started.

CBC works collaboratively with design teams to identify relevant Building Regulations matters and provide practical feedback.

This can help architects and developers consider possible changes before work progresses on site.

Early discussions are particularly valuable where a project has more complex design requirements.

What Happens with More Complex Projects?

Not every development can be assessed through a straightforward application of the guidance in the Approved Documents.

CBC’s Building Control service explains that the Building Regulations allow flexibility in how compliance may be demonstrated.

For more complex projects, CBC’s Registered Building Inspectors work with the design team to consider practical approaches where appropriate.

The aim is to assess how the design can demonstrate compliance with the applicable requirements.

Can You Discuss Plans Before Making a Building Regulation Application?

Yes. CBC offers a dedicated Pre-Application Advice service, subject to appointment instruction.

This gives architects and developers the opportunity to discuss a proposed development before submitting a full Building Regulation Application.

CBC can provide practical interpretation of the relevant Approved Documents and discuss potential issues affecting the design.

Depending on the circumstances, discussions can take place by email, telephone or meetings with the design team.

What Happens After the Plans Have Been Considered?

Plan examination forms part of CBC’s wider Building Control service.

Depending on the project, this can also involve statutory consultations with the relevant authorities, site inspections during construction and the completion process.

CBC works with the design and site teams to provide continuity throughout these stages.

When the project has been successfully completed and the necessary paperwork and certification are in order, CBC can issue the Final Certificate.

Frequently Asked Questions

Does CBC offer plan checking?

Yes. CBC can undertake detailed plan examinations where required as part of its Building Control service.

Can architects discuss plans before submitting an application?

Yes. CBC provides Pre-Application Advice, subject to appointment instruction.

Are the same requirements considered for every project?

No. The relevant requirements depend on the type and complexity of the development.

Does Building Control finish after plan checking?

No. The wider process may also include statutory consultations, site inspections and completion certification.

What Is Needed Before a Final Certificate?

Completing building work is an important milestone, but reaching the end of construction does not automatically mean the Building Control process is complete.

Before Complete Building Control Ltd (CBC) can issue a Final Certificate, the necessary paperwork, certification and compliance information must be in order.

One important part of this process is the submission of Compliance Declarations by the relevant duty holders.

What Are Building Control Compliance Declarations?

Compliance Declarations form part of the duty holder requirements introduced through changes to the Building Regulations framework.

CBC explains on its Building Regulations guidance page that, under Regulation 18 of the Building (Registered Building Control Approvers etc.) (England) Regulations 2024, the required Compliance Declarations must be submitted before a Final Certificate can be issued.

These declarations are an important part of the documentation associated with the completion of building work.

Who Needs to Provide Compliance Declarations?

CBC identifies the relevant duty holders as:

• The Client
• The Principal Designer
• The Principal Contractor

The required declarations must be completed, signed and dated before submission.

CBC acknowledges receipt of the required declarations as part of its completion procedures.

What Happens if a Declaration Is Missing?

There may be circumstances where a client cannot obtain the necessary declaration from the Principal Designer or Principal Contractor.

CBC’s published regulatory guidance explains that, following amendments in 2025, a client may provide a statement explaining the circumstances where the required declarations cannot be obtained.

CBC must consider the statement and determine whether it can be accepted.

This is not an automatic alternative to providing the required declarations, and individual circumstances must be assessed.

Clients experiencing difficulties obtaining completion documentation should contact CBC to discuss their position.

What Else Is Considered Before a Final Certificate?

Compliance Declarations are one part of the wider completion process.

CBC’s published guidance also identifies the importance of:

• Necessary commissioning certificates
• Completion information
• Outstanding issues identified during previous site inspections
• Relevant statements and certification
• Internal checks before the Final Certificate is issued

The requirements will depend on the individual project and the information needed to demonstrate compliance.

Why Is It Important to Prepare Completion Documentation?

Building Control involves more than the examination of plans and inspections during construction.

The completion stage also requires the relevant information to be available so that outstanding matters can be considered and the project can be brought to a satisfactory conclusion.

Maintaining communication between the client, design team, contractor and Building Control team can help make this process more straightforward.

How Complete Building Control Can Help

Complete Building Control Ltd is a Registered Building Control Approver providing professional Building Control services for domestic and commercial projects.

CBC works with clients, architects, designers and contractors throughout the Building Control process, from plan examination and statutory consultations through to site inspections and completion.

If you are approaching completion and need information about Compliance Declarations, visit our Building Regulations guidance page.

You can also find out more about our Building Control services.

Frequently Asked Questions

Are Compliance Declarations required before a Final Certificate?

CBC’s published guidance explains that the required Compliance Declarations must be submitted before a Final Certificate can be issued.

Who are the relevant duty holders?

CBC identifies the Client, Principal Designer and Principal Contractor as duty holders.

What if I cannot obtain a declaration?

CBC’s regulatory guidance explains the circumstances in which a client may submit a statement for consideration. Acceptance is not automatic.

Does completing construction mean a Final Certificate can be issued immediately?

Not necessarily. The necessary documentation, certification, outstanding matters and internal checks must also be addressed.

Building Control for a Commercial Refurbishment

Commercial refurbishment projects can range from relatively straightforward alterations through to significant changes involving layouts, structure, fire safety, accessibility and building services.

As a result, one of the questions that should be considered early in a refurbishment project is how the proposed work will be affected by the Building Regulations and whether Building Control involvement is required.

Complete Building Control Ltd (CBC) is a Registered Building Control Approver providing professional Building Control services for residential, commercial and mixed-use developments.

Does a Commercial Refurbishment Require Building Control?

Whether Building Control involvement is required will depend on the nature and extent of the proposed work.

A commercial refurbishment may involve work that falls within the requirements of the Building Regulations, particularly where the project includes:

• Structural alterations
• Changes to the building layout
• Fire safety considerations
• Ventilation
• Thermal performance
• Accessibility
• Changes to other regulated elements of the building

For this reason, Building Control should be considered at the beginning of the project rather than waiting until construction is ready to start.

Why Early Building Control Advice Can Help

Decisions made during the design stage can have a significant impact on how easily a project progresses during construction.

Discovering a compliance issue once work is already underway can potentially result in alterations, additional costs or delays.

CBC offers Pre-Application Advice, subject to appointment instruction, to architects and developers, providing an opportunity to discuss a proposed project before making a full Building Regulation Application.

Our Registered Building Inspectors can consider key aspects of the proposal and provide a practical interpretation of the relevant Approved Documents.

Fire Safety

Fire safety can be an important consideration in commercial refurbishment projects.

Changes to internal layouts, escape arrangements and the way different parts of a building are used can all have implications for the design.

Where applicable, CBC also manages the necessary statutory consultation with the Fire Authority as part of its Building Control service.

Considering these requirements during the design stage gives the project team an opportunity to address potential issues before construction progresses.

Accessibility

Commercial alterations may also need to consider accessibility requirements.

The requirements will depend on the building and the proposed work, but accessibility can form an important part of the wider Building Regulations assessment.

CBC’s Pre-Application Advice service can help architects and developers consider relevant accessibility requirements during the design stages of a project.

Thermal Performance and Ventilation

A refurbishment can also affect the thermal performance and ventilation of a building.

Changes to the building fabric and other elements of the development may introduce Building Regulations considerations relating to thermal performance or ventilation.

The exact requirements will depend on the nature and extent of the individual project, which is another reason why early assessment can be beneficial.

Structural Alterations

Commercial refurbishment projects can involve changes to the existing layout or structure of a building.

Where structural elements are affected, appropriate plans, calculations or other supporting information may need to be considered as part of the Building Control process.

Where required, CBC can undertake a detailed plan examination and work alongside the project’s design team as the proposals develop.

Building Control Inspections During the Refurbishment

Building Control involvement continues once the project moves from the drawing board to the construction site.

CBC’s Registered Building Inspectors undertake the necessary inspections during the construction phase.

The site team should keep Building Control informed as the work progresses so that inspections can be arranged at appropriate stages and relevant construction elements can be assessed before they are covered.

Completing the Building Control Process

At the end of the refurbishment, the relevant paperwork, certification and compliance information will need to be in order.

Current requirements also mean that the relevant duty holders must provide the necessary Compliance Declarationsbefore CBC can issue the Final Certificate.

Thinking about the necessary documentation throughout the project rather than waiting until the end can help make the completion process more straightforward.

Planning a Commercial Refurbishment?

If you are planning a commercial refurbishment, alteration or development, involving Building Control during the early stages can help identify potential issues before construction begins.

Complete Building Control Ltd provides professional Commercial Building Control services and works alongside clients, architects, developers and construction teams from the initial stages of a project through to completion.

A guide to Building Control in Cheshire

Whether you are extending a home, altering an existing building or planning a commercial development, Building Control is an important consideration from the early stages of a project.

Complete Building Control Ltd (CBC) provides professional Building Control services across Cheshire, supporting homeowners, architects, developers, designers and contractors through the Building Regulations process.

CBC is a Registered Building Control Approver and has a regional office in Cheshire, providing Building Control support across the surrounding areas.

When Is Building Control Required?

Building Regulations apply to many types of building work.

Depending on the project, this can include:

• Extensions and renovations
• Structural alterations
• Property conversions
• New developments
• Commercial and office developments

The requirements will depend on the type and complexity of the work being undertaken.

It is also important to remember that Building Control and Planning Permission are separate processes. A project may require Building Control involvement regardless of its Planning Permission requirements.

Starting the Building Control Process Early

One of the most useful steps architects, developers and clients can take is to consider Building Control early in the development of a project.

Waiting until construction is underway can make potential compliance issues more difficult and expensive to resolve.

CBC offers Pre-Application Advice, subject to appointment instruction, allowing architects and developers to discuss a proposed project before making a full Building Regulation Application.

This can include consideration of areas such as fire safety, thermal requirements and disabled access.

Plan Checking and Design Support

Where required, CBC can undertake a detailed examination of plans to assess how the proposed design addresses the relevant Building Regulations requirements.

Our Registered Building Inspectors work with design teams to provide practical guidance and help identify potential issues.

On more complex projects, there may be different ways of demonstrating compliance with the Building Regulations. Early communication between the design team and Building Control can be particularly valuable in these circumstances.

Statutory Consultations

Depending on the nature of the project, statutory consultations may also be required.

As part of its Building Control service, CBC can manage applicable consultations with the relevant Sewage Authority and Fire Authority, collating the feedback so that the design team can respond to matters raised.

Building Control Inspections

Once work starts on site, Building Control inspections form an important part of the process.

CBC’s Registered Building Inspectors undertake the necessary site inspections during construction, working with the site team so that inspections can take place at the appropriate stages.

The exact inspections required will depend upon the nature and complexity of the individual project.

Keeping the Building Control team informed as construction progresses helps ensure that relevant elements can be inspected before they are covered.

From Design Through to Completion

Building Control should be considered as part of the complete development process rather than simply an inspection that takes place during construction.

CBC can support projects through plan examination, statutory consultations where applicable, site inspections and the completion process.

Before the Final Certificate can be issued, the necessary documentation must also be provided, including the required Compliance Declarations from the relevant duty holders.

Once the project has been satisfactorily completed and the necessary documentation has been received and accepted, CBC can proceed with the Final Certificate process.

Building Control Across Cheshire

With an office in Cheshire, CBC provides a responsive Building Control service across the surrounding region.

Building Control in London – What are your options?

If you are planning a building project in London, Building Control is an important part of ensuring that the work complies with the Building Regulations.

For homeowners, architects, developers and contractors, considering Building Control early can help a project progress more smoothly and identify potential compliance issues before they become more difficult or costly to resolve.

Complete Building Control Ltd (CBC) is a Registered Building Control Approver providing professional Building Control services across London and other areas of England.

What Is Private Building Control?

Private Building Control allows you to appoint a Registered Building Control Approver in London rather than using the Building Control department of the local authority for eligible projects.

The purpose remains the same – to assess building work against the requirements of the Building Regulations.

CBC’s Registered Building Inspectors work with clients, architects, designers, builders and developers throughout the Building Control process, providing practical support from the design stages through to completion.

What Does a Registered Building Control Approver Do?

Building Control can involve considerably more than simply visiting a construction site.

Depending on the project, CBC’s Building Control service can include:

• Detailed examination of plans where required
• Advice and liaison with the design team
• Statutory consultations where applicable
• Site inspections during construction
• Assessment of supporting information and certification
• Support through to completion and the issuing of the Final Certificate

Getting Building Control involved at an appropriate stage can make it easier to identify potential issues while a project is still being designed.

Building Control for London Projects

CBC provides Building Control services covering the London area, working with homeowners and construction professionals on a range of developments.

Building Regulations requirements will vary according to the nature and complexity of the individual project.

Areas such as structural safety, fire safety, accessibility, ventilation and thermal performance may all need to be considered as part of the design.

For architects and developers, having access to Building Control advice during the design process can therefore be particularly valuable.

Pre-Application Advice

CBC offers Pre-Application Advice, subject to appointment instruction, which allows architects and developers to discuss a proposed project before making a full Building Regulation Application.

Our Registered Building Inspectors can provide a practical interpretation of the Approved Documents and consider important areas such as fire safety, thermal requirements and disabled access.

Identifying potential issues during the design stage can help reduce the likelihood of unforeseen changes and costs once construction is underway.

Plan Examination

Where required, CBC can undertake a detailed examination of the proposed plans.

This provides an opportunity for the design team to demonstrate how the relevant requirements of the Building Regulations will be met and to address potential issues before or during construction.

For more complex developments, CBC’s Registered Building Inspectors can work with the design team to consider practical ways of demonstrating compliance.

Site Inspections During Construction

Building Control continues throughout the construction phase.

CBC’s Registered Building Inspectors undertake the necessary site inspections as work progresses, working with the site team so that inspections can be arranged at the appropriate stages.

Good communication throughout construction is important so that relevant elements of the work can be inspected before they are covered or become difficult to assess.

What Happens When the Project Is Complete?

Building Control does not finish with the last site inspection.

Before a Final Certificate can be issued, the necessary project documentation must be in place. This includes the required Compliance Declarations from the relevant duty holders.

Once the works have been satisfactorily completed and the necessary documentation has been received and accepted, CBC can proceed with the Final Certificate process.

This is why Building Control should be considered throughout the entire development, from the initial design stages through construction and ultimately to completion.

Looking for Building Control in London?

If you are planning a domestic or commercial project in London, Complete Building Control Ltd can provide professional Building Control support from the early stages of the development through to completion.

Our team works with homeowners, architects, developers, designers and contractors, providing a practical and responsive approach to Building Regulations compliance.

Contact Complete Building Control Ltd to discuss your London project or request a quotation.

One of the questions we’re often asked by clients is what a Building Control inspection actually involves. The answer depends on the project and, importantly, what stage the work has reached.

At Complete Building Control Ltd, our Registered Building Inspectors work with site teams throughout construction, carrying out the necessary inspections at the appropriate stages of the project.

Why are Building Control inspections needed?

Building Control inspections allow relevant elements of the work to be inspected as construction progresses.

Timing is important. Some parts of a building are very easy to inspect while work is underway but much more difficult once concrete has been poured, walls have been closed up or finishes have been applied.

That’s why we work closely with the site team to make sure inspections are carried out at the right stages.

What might a Building Inspector look at?

There isn’t a single inspection checklist that applies to every project.

A domestic extension will have very different requirements to a large commercial development, for example.

Depending on the project, inspections may look at areas such as foundations, drainage, structural work, insulation and other relevant elements of the construction.

The inspector will consider the work in relation to the Building Regulations and the information provided for the project.

What about structural work?

Structural alterations are a common reason for Building Control involvement.

This might include steelwork, alterations to load-bearing walls, new openings or more substantial structural elements on larger developments.

Where structural calculations, drawings or other supporting information form part of the project, these may also need to be considered alongside the work taking place on site.

Fire safety, thermal performance and accessibility

Building Regulations cover much more than the structure itself.

Depending on the development, the project may also need to demonstrate compliance in areas including fire safety, thermal performance, ventilation and accessibility.

These are areas where early discussions can be particularly useful.

Through our Pre-Application Advice service, CBC can work with architects and developers before a full Building Regulation Application is made, helping the design team identify potential issues before construction begins.

Do I need to wait for the Building Inspector before continuing work?

The important thing is to keep your Building Control team informed about the progress of the project and arrange inspections when required.

If work that needs to be inspected is covered before an inspection takes place, it can make demonstrating compliance more difficult.

Good communication between the contractor, client and Building Control team can make the process much smoother.

What happens at the end of the project?

Building Control doesn’t begin and end with a single site visit. Inspections form part of the wider Building Control process, alongside the assessment of plans and supporting information and, where necessary, statutory consultations.

When the project has been successfully completed, and all of the necessary paperwork and certification are in order, CBC issues the Final Certificate.

Need a Building Control inspection?

If you’re already working with Complete Building Control Ltd, you can request your next site inspection through our Inspection Request Form.

If you’re planning a new domestic or commercial project and would like CBC to provide your Building Control service, get in touch with our team to discuss the development.

Complete Building Control Ltd provides practical, professional Building Control support from the design stage through to completion.

 

Planning an extension, conversion, refurbishment or new development in Birmingham? One of the things you’ll need to consider is whether your project needs Building Regulations approval.

It’s an area that can sometimes cause confusion, particularly because Building Regulations and Planning Permission are not the same thing.

A project may not need Planning Permission but can still need Building Control involvement.

What do Building Regulations cover?

Building Regulations set standards for the design and construction of buildings and cover important areas such as:

• Structural stability
• Fire safety
• Ventilation
• Drainage
• Energy efficiency
• Thermal performance
• Accessibility

Exactly what applies will depend on the type and complexity of your project.

At Complete Building Control Ltd, our Registered Building Inspectors work across both domestic and commercial developments, so the approach we take is tailored to the individual project.

What sort of projects need Building Control?

Building Regulations can apply to a wide range of work.

For homeowners, this commonly includes extensions, loft and garage conversions, structural alterations and new-build properties.

For commercial clients and developers, Building Control can be involved in everything from alterations to existing premises through to much larger development projects.

The requirements can vary considerably, which is why it’s always worth establishing what’s required before work gets underway.

What happens at the design stage?

Where required, Complete Building Control can carry out a detailed examination of the plans for the proposed development.

This allows us to look at the design against the relevant requirements of the Building Regulations and Approved Documents.

For more complicated projects, there isn’t necessarily a one-size-fits-all solution. Our Registered Building Inspectors can work with architects and design teams to consider practical ways of demonstrating compliance where appropriate.

CBC can also manage the necessary statutory consultations with the Sewage Authority and Fire Authority on behalf of our clients.

Is it worth speaking to Building Control early?

Yes, absolutely. We’ve seen how useful early Building Control involvement can be, particularly where a project has more complicated fire safety, thermal, accessibility or construction requirements.

Complete Building Control offers a dedicated Pre-Application Advice service which allows architects and developers to discuss a proposed project with our team before making a full Building Regulation Application.

It gives us an opportunity to highlight potential issues while the project is still being designed.

Finding a problem on a drawing is generally much easier than trying to rectify it once work has started on site.

What happens during construction?

Once construction is underway, our Registered Building Inspectors carry out the necessary site inspections at the relevant stages of the project.

We work closely with the site team to make sure inspections are arranged at the right time, helping to avoid unnecessary delays and ensuring important elements of the work can be inspected before they are covered.

Once the project has been successfully completed and all of the required paperwork and certification are in order, CBC issues the Final Certificate.

Looking for Building Control in Birmingham?

Complete Building Control Ltd provides Building Control services for domestic and commercial projects, with our Head Office based in Birmingham.

If you’re planning building work, you may have heard the term private Building Control and wondered what it means or how it differs from using your local authority.

For many building projects in England, you have a choice over who provides your Building Control service. Complete Building Control Ltd (CBC) provides a professional Building Control service for domestic and commercial projects, working with homeowners, architects, developers and contractors from the design stage through to completion.

What is private Building Control?

Private Building Control allows you to appoint a Registered Building Control Approver rather than using the Building Control department of the local authority.

The purpose remains the same – to assess building work against the requirements of the Building Regulations.

These regulations cover a wide range of areas including structural safety, fire safety, drainage, ventilation, energy efficiency and accessibility.

It is also worth remembering that Building Control and Planning Permission are separate. Depending on the work you are undertaking, your project may need both.

What does CBC do?

Every project is different, which is why we tailor our Building Control service to the particular development.

Where required, we can undertake a detailed examination of the plans and supporting information. This helps designers establish whether the proposals demonstrate compliance with the Building Regulations before construction progresses.

For more complex projects, our Registered Building Inspectors can also work directly with the design team to look at practical ways of demonstrating compliance.

We can also manage the relevant statutory consultations with the Sewage Authority and Fire Authority on behalf of our clients, collating the feedback so that the design team can respond to any issues raised.

What happens once work starts?

Our involvement continues throughout construction.

Our Registered Building Inspectors carry out the necessary site inspections as the project progresses, working with the site team to make sure inspections take place at the right stages.

The inspections required will depend on the project, but the important point is that Building Control should be kept informed as work progresses. This means relevant elements of the construction can be inspected before they are covered up.

What happens when the project is finished?

Once the project has been successfully completed and the necessary paperwork and certification are in order, CBC can issue the Final Certificate.

This is why we encourage clients to think about Building Control as part of the whole project rather than something that only needs to be dealt with at the end.

Can you speak to CBC before submitting an application?

Yes, and on many projects this can be extremely useful. Our Pre-Application Advice service gives architects and developers the opportunity to discuss a project with us before making a full Building Regulation Application.

We can look at key areas such as fire safety, thermal requirements and accessibility, helping the design team identify potential issues at an early stage.

Often, dealing with an issue while a project is still on the drawing board is much easier and less costly than trying to rectify it once construction has started.

Looking for private Building Control?

Requests for Part Final Certificates are becoming more common place. This guidance note looks to bring about a common understanding and interpretation of the approach Complete Building Control Ltd should take.

Occupation Prior To Completion Of Works

Regulation 19 Building (Registered Building Control Approvers etc.) (England) Regulations 2024 allows for the occupation of a building prior to completion but limits the period, of occupation without final certificate, to

• 4 weeks for works where the RRO applies, and;
• 8 weeks for other works

If the Final Certificate is not issued within the appropriate time limit the InitialNotice would cease to be in force.
Potentially an extension of time under Regulation 19 (7) could be applied for but care must be taken to ensure this is justifiable and the client is not “playing the system”.

Partial Final Certificates

Complete Building Control Ltd will issue Partial Final Certificates, but the Duty Holders must document their approach to compliance of that part and its interaction with any incomplete elements of the building for consideration before we agree to the approach in principle.

Key considerations are:

1. The works subject to the Part Final Certificate must be clearly and precisely defined, it may be helpful for the Duty Holders to support their description with drawings marked to show the extent of the applicable works.

2. That the part subject to the request for a Final Certificate is complete and can be occupied safely and independently of any ongoing works on the remainder of the project. All parts of the Building Regulations need to be considered but particular care should be taken over Parts A, B, F, H, L, M and S Approved Documents.

3. If required, the Fire Authority have been consulted prior to completion in accordance with Regulation 9 The Building (Registered Building Control Approvers etc.) (England) Regulations 2024)

Consider all provisions under Regulation 4 of The Building (Registered Building Control Approvers etc.) (England) Regulations 2024 – Functions of the Approvers to ensure requirements can be met for the part of the building not just the whole. This may be seen as particularly problematic in terms of the provision of EPCs, but if the Duty Holders are seeking a Partial Final Certificate, they must provide an EPC for the “completed part”.

4. Has the Principal Designer and Principal Contractor under the The Construction (Design and Management) Regulations 2015
made adequate provision to ensure the independence and safety of the “completed part” is maintained whilst site activity continues.

Consideration should be made to ensure:

a. – No site activity, delivery through common parts is undertaken.

b. – Maintenance of access for Fire Authority at all times, both inside
and outside of the building (including site access).

c. – Independence of all active fire systems and mechanical services
serving the “completed part”.

d. – Maintaining structural integrity of the “completed part”.

e. – Maintaining drainage to “completed part”

As with a full Final Certificate, the Duty Holders must ensure that:

5. All relevant requirements, in terms provision of testing and information,Part 6 to Part 9 of the Building Regulations 2010 have been satisfactorily met.

6. The Duty Holders have provided their Declarations of Compliance 3 underRegulation 18 The Building (Registered Building Control Approvers etc.)(England) Regulations 2024 with regards to “completed part”.

KEY NOTE:

RBIs are not duty bound to accept the request for the issue of a Part Final Certificate. Key to accepting the proposal is the Duty Holders evidencing that they have satisfactory fulfilled their duty to plan, manage and monitor in relation to the request. It may be appropriate to remind the Duty Holders that they alone are responsible for allowing occupation and that this decision is subject to the same plan, manage and monitor principle.

The above is not an exhaustive list of considerations. At all times the RBI should be inquisitive. Where the RBI is uncertain about the appropriateness of giving a Part Final Certificate, the consideration should be peer reviewed by a Class 4 Technical Manager or Director of Complete Building Control Ltd.
