What building works should comply with Building Regulations?
The following types of project amount to ‘Building Work’ as defined in Regulation 3 of the Building Regulations:
- the erection or extension of a building
- the installation or extension of a service or fitting which is controlled under the regulations
- an alteration project involving work which will temporarily or permanently affect the ongoing compliance of the building, service or fitting with the requirements relating to structure, fire, or access to and use of buildings
- the insertion of insulation into a cavity wall
- the underpinning of the foundations of a building
If you are planning to carry out such work, then it should comply with the Building Regulations.
The works must meet Building Regulations’ technical requirements and not make other parts of the building less compliant or unsafe.
For example, replacing external windows or doors should maintain or exceed the previous compliance level with standards.
- means of escape from fire
- air supply for combustion appliances and their flues
Also, in this example, the replacement window / door should also fully satisfy the requirements for energy conservation and ventilation for health.
The Building Regulations may also apply to certain changes of use of an existing building. This is because the change of use may result in the building as a whole no longer complying with the requirements which will apply to its new type of use, and so having to be upgraded to meet additional requirements specified in the regulations for which building work may also be required.
