Building Control inspections are an important part of the construction process, helping to assess whether building work is being carried out in accordance with the relevant Building Regulations.
If you're undertaking a new build, extension, conversion or commercial development, you may be wondering what happens during an inspection, what the inspector will look for and when visits need to take place.
In this guide, we explain what to expect from a Building Control inspection and why arranging inspections at the appropriate stages is important.
What is a Building Control inspection?
A Building Control inspection is an assessment of building work at relevant stages of construction.
The purpose is to check that the work being carried out meets the applicable Building Regulations requirements. The areas assessed will depend on the type of project, the approved details and the work taking place.
Inspections may involve reviewing elements such as:
Foundations and ground conditions.
Structural work, including beams and supporting elements.
Damp-proof courses and protection against moisture.
Drainage and underground services.
Fire safety measures.
Insulation and energy efficiency.
Ventilation and other building services.
Final elements of the completed building.
Not every inspection will cover all of these areas. The inspection requirements will depend on the individual project.
When do Building Control inspections take place?
Inspections are generally arranged at key stages of construction, when important elements of the work can be assessed before they are covered up or become inaccessible.
Depending on the project, these stages may include:
1. Commencement of work - Building Control may need to be notified when work starts, in accordance with the applicable procedures and project requirements.
2. Foundations - Where relevant, an inspection may be required before concrete is poured to assess the excavation, ground conditions and suitability of the foundations.
3. Drainage - Drainage installations may need to be inspected before they are covered over, allowing the relevant pipework and connections to be assessed.
4. Structural elements - Structural work, including beams, lintels and other supporting elements, may be inspected to assess whether it has been carried out in accordance with the relevant design information.
5. Completion - A final inspection may be arranged once the building work is substantially complete. This allows the inspector to assess the completed work and identify whether any outstanding items need to be addressed.
The stages above are examples rather than a standard inspection schedule for every project. Your inspection requirements will depend on the nature and complexity of the work.
What does the inspector look for?
During an inspection, the Building Control professional will assess the relevant elements of the construction against the applicable Building Regulations requirements.
This may include checking that:
The work broadly reflects the submitted plans and supporting information.
Structural elements have been installed appropriately.
Relevant fire safety provisions have been incorporated.
Insulation and ventilation requirements have been considered.
Drainage and other building services have been installed appropriately.
Materials and construction details are suitable for their intended purpose.
The inspector may also request further information, photographs, certificates or supporting documentation where necessary.
What happens if something needs attention?
If an inspection identifies work that requires further attention, the inspector will communicate the relevant findings and explain what needs to be addressed.
This could involve requesting additional information, asking for corrective work or arranging a further inspection once the issue has been resolved.
It is important that any outstanding matters are dealt with as soon as reasonably possible to help keep the project moving towards completion.
How do I arrange a Building Control inspection?
The process for arranging an inspection will depend on your Building Control provider and the requirements agreed for your project.
At Delta Building Control, clients and project teams can contact us to arrange inspections at the relevant stages of construction.
It is important to provide sufficient notice and avoid covering up elements of work that may need to be inspected before they become inaccessible.
Your project team should familiarise themselves with the inspection arrangements and any specific requirements set out for the project.
Does a Building Control inspection mean the work is approved?
A Building Control inspection is an assessment of the work visible at a particular stage. It should not be treated as a guarantee that every aspect of the construction complies with the Building Regulations.
Inspections are carried out at relevant stages and are not a substitute for the responsibilities of the client, designers and contractors involved in the project.
The builder and other dutyholders remain responsible for carrying out their respective duties and ensuring the work complies with the applicable requirements.
What happens after the final inspection?
Once the work is complete, the Building Control body will consider the inspection findings and any outstanding information or documentation required.
Where the relevant requirements have been met, the appropriate completion documentation can be issued.
For eligible projects under the Registered Building Control Approver route, this may include a Final Certificate, which is submitted to the relevant Local Authority.
It is important to keep completion documentation safely alongside the other records for your property or project.
