Do I need building regulation approval?

Do I need building regulation approval?

Certain building works that you do at home or at work will need to comply with minimal standards set down by law. For these works you'll need building regulations approval to show they meet these standards

A completion certificate will be issued when all stages have been inspected and meet regulations. This is an important document, as it tells you that the work meets the minimum requirements of the building regulations. The certificate will be required if or when you come to sell your property, or if you raise a secured loan or mortgage against your property.

You could be fined or required to pay to get the work re-done if non-compliant work is discovered.

Note that building regulations approval is different from planning permission and you may need both.

When do I need approval?

Building regulations cover the construction and extension of buildings. You may also need approval for alterations such as:

  • electrical work
  • installing a bathroom
  • replacing windows and doors
  • replacing roof coverings
  • installing or replacing a heating system and boiler
  • putting in a fixed air-conditioning system

You can find a registered electrician in the Competent Persons Register
