Replacement windows and doors

inspectwindowSince 2002, Building Regulations have applied to all replacement glazing. The regulations apply specifically to thermal performance and other areas such as safety, air supply, means of escape and ventilation of replacement windows and doors.

When the time comes to sell your property, your purchaser’s surveyors will ask for evidence that any replacement glazing installed after April 2002 complies with the Building Regulations.

Proving compliance

  • There are two ways to prove compliance - a certificate showing the work has been carried out by an installer registered under FENSA Certass or BSI or by ensuring the work is inspected by our Building Control team.

Companies registered under FENSA, Certass and BSI schemes, which meet certain criteria, are able to self-certify their work complies with the Building Regulations.

They inform us of all completed installations and issue the building regulations compliance certificate to you as the householder. If you make a building notice application to us, we will inspect the work has been carried out correctly and issue you with the completion certificate.

If you are a householder

Before you sign a contract to buy replacement glazing ask whether the installer is able to self-certify under one of the above schemes. If not, they, or you will need to make an application using a building notice application form and pay the relevant fee.

The building notice application fee for replacement of windows and doors from 1 April 2013 until 31 March 2014 is £218 inc VAT for up to 20 windows and doors: 

As the owner of the property, you are responsible for making sure the work complies with Building Regulations.
