Your Building Control Application


After you receive your planning permission for your single or double storey extension or for your loft extension, you can begin your application to Building Control (for your Building Regulations for extensions). The Government Building Regulation rules set the construction standard for design and building works for alterations to existing properties and new builds. Building Regulations are put in place to ensure health and safety for people in and around both public and private buildings.

The Whole Process

We can manage the entire process on your behalf, from the application & drawings to approval. The local authority’s Building Control department, or a private certified approved building inspector, will check the building regulation drawings to ensure they comply with current UK regulations. Once the drawings have been approved, the Building Control inspector or the approved inspector will visit the construction site at critical stages of the build to ensure that the building work carried out is to a sufficient standard of safety and with appropriate materials.


Building Regulations for extensions: the outcome

At the end of construction, the building inspector will visit the site with a view to issuing a final completion certificate to prove that all works completed complied to the UK regulations. The building inspector has the power to refuse the completion certificate if the building work does not comply with all the essential requirements. It is therefore vital that you choose a company which has good experience with Building regulation rules to ensure that your project is issued with a completion certificate.
