Replacement Windows or Doors

From April 2002, all replacement glazing came into the scope of the Building Regulations. From that point onwards, anyone who installs replacement windows or doors must comply with strict thermal performance standards.

When the time comes to sell your property, your purchasers' surveyors will ask for evidence that any replacement glazing installed after April 2002 complies with the new Building Regulations. There are two ways to prove compliance:

  • A certificate showing that the work has been done by an installer who is a member of a competent person scheme, i.e. BSI, CERTASS, FENSA, and can therefore self-certify that their work complies with the Building Regulations.
  • A certificate from the local authority saying that the installation has approval under the Building Regulations i.e. inspected by local authority Building Control Officer.

Before you sign a contract to buy replacement glazing, be sure to ask whether the supplier/installer is able to self-certify. If not, an application will need to be submitted to the local authority for approval under the Building Regulations, with the appropriate charge.

You can submit a Building Notice application for replacement windows and doors through our online submission form, or a downloadable version of the Building Notice form and current Schedule of Fees can be found HERE.
