Building Regulations

What are Building Regulations?

The Building Regulations are developed by the Government and approved by Parliament. They are minimum standards for design, construction and alterations to nearly every building.

The Building Regulations also contain a list of requirements that ensure minimum standards for health, safety, convenience, energy efficiency, welfare and sustainability. These are referred to as Schedule 1 and they also aim to prevent misuse, abuse or contamination of water supplies.

These regulations cover all aspects of construction including foundations, stability, damp-proofing, insulation, heating, ventilation, fire protection, means of escape and making sure there are adequate facilities for people with disabilities.

Building Regulations consist of Parts A – P and are regularly being updated.

Below are brief explanations of each part and a link to the documents themselves.

Where to get approval?

It is down to Building Control Bodies to ensure compliance with Building Regulations. There are two types and it is your choice who you choose.
Local Authority Building Control (LABC) – each local authority in England and Wales has a building control section.
Approved Inspector Building Control (AIBC) – approved inspectors are companies or individuals authorised under the Building Act 1984 to carry out building control work in England and Wales.
If you use a LABC then you can either make a full plans application or give a Building Notice. A building notice is really only appropriate for small jobs as no plans are required and the job will get inspected as you go along. Therefore if something does not comply you may have already done the work before the building control officer informs you that there is a problem. You also will not get a final certificate to show the works comply.
If you use an AIBC then it is like a full plan application and the AIBC will inform your LABC that they have been asked to oversee the work by sending them an Initial Notice.
