The Building Regulations cover most types of building work. For example, new buildings, extensions or alterations to existing buildings, loft conversions, the installation or alteration of drainage or combustion appliances, structural alterations and some changes of use all require the submission of a Building Regulation application.

There are some works to which the regulations do not apply, please refer to the section on Exempt Buildings and work

If you are unsure whether any work will require a Building Regulation application please contact Building Control for guidance.

There is a very useful interactive guide on the Planning Portal website that gives details of building regulation requirements on many common types of house alterations and extensions. See the following link - interactive house guide

Limitation On Requirements

There is an important limitation that applies to all the building regulations with the exception of the requirements for conservation of fuel and power and access and facilities for disabled people. This limitation ‘shall not require anything to be done except for the purpose of securing reasonable standards of health and safety for persons in or about buildings and any others who may be affected by buildings or matters connected with buildings’. The limitation makes it clear that building regulations make no provision for property protection or the quality of finishes to works.

Building work must be carried out with appropriate and proper materials which should be used or fixed in a workmanlike manner.

Proper materials include materials that bear an EC Mark in accordance with the Construction Products Directive of the EC or conform to a harmonised standard or European technical approval, a British Standard or British Board of Agrément (BBA) Certificate or other equivalent specification issued by a member of the EC.
