WHAT ARE THEY?- This project is an overview of the Building Regulations. For information and an explanation of each individual regulation please see the appropriate project.

All building work has to comply with the building regulations, which are part of the Building Act 1984 (Amended by the building regulations act 1991). These regulations stipulate the precise method of constructing a building in, at the moment, 13 different areas of construction. The regulations are updated, amended or changed from time to time and your builder should be conversant with the changes, via the architect. The regulations only affect the new work being undertaken when done as an addition to an existing building or on a “stand alone” basis. It is not necessary to bring any existing structure into line with the current regulations unless stipulated by the local authority.

There is a legal requirement for all new building work to comply with building regulations and even when no planning permission is needed, building regulations may be. You can get this advice from your Local Authority.

Where building regulations have to be complied with, the “Building Control” office of your local council will appoint an officer (BCO- Building Control Officer) to inspect the work at regular intervals to make sure it complies.

It is also possible to arrange with the NHBC (National House Building Council), who are licensed to inspect building control, to do the same job. The NHBC also operate a 10 year guarantee on the work they approve.

The costs of the above will depend on the work involved.

Please note with all of the above it is important to contact your local council to make sure you comply with your obligations.
