Common building projects

 

If you are employing a builder, the responsibility will usually be theirs. You must confirm this at the very beginning. You should know that if you are the owner of the building, it is you who will be served with an enforcement notice if the work does not follow the regulations.

Some kinds of building projects are exempt from the regulations. But generally, if you are planning to carry out 'building work' as defined in regulation 3 of the building regulations, then it must follow the building regulations.

This means that the regulations will probably apply if you want to:

  • Put up a new building
  • Extend or alter an existing one

This also includes providing services or fittings such as:

  • Washing and sanitary facilities,
  • Hot water cylinders,
  • Foul water and rainwater drainage,
  • Replacement windows,
  • And fuel-burning appliances of any type

The works themselves must meet the technical requirements in the building regulations.

They must not make other fabric, services and fittings less compliant or dangerous than they were before.

For example, the replacement double-glazing must not make compliance worse for means of escape etc.

They may also apply to 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. Due to its new use, it will have to be upgraded to meet the requirements specified in the regulations.

See here for changes or alterations to buildings 

In summary, the following types of project amount to 'building work':

  • 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
  • Work affecting the thermal elements, energy status or energy performance of a building

Before commencing work you should refer to Regulation 3 of the Building Regulations for the full meaning of 'building work' or, if you are unsure, seek advice.
