Windows, doors and roof-light application

From April 2002, all replacement glazing came within the scope of the Building Regulations. One of the main reasons for the change is the need to reduce energy loss. 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 new Building Regulations.

You can prove compliance by providing one of the following:

• a certificate showing that the work has been done by an installer who is registered under the FENSA scheme 
• a certificate from Building Control saying that the installation has approval under the Building Regulations

The FENSA Scheme allows registered installation companies to self-certify that their work complies with the Building Regulations. FENSA will inform Local Authorities of all completed FENSA installations and issue certificates to the householder.

Before you sign a contract to buy replacement glazing, be sure to ask whether the installer is able to self-certify. If not, they, or you will need to make an application to Building Control and pay any relevant charge. As the house owner, you are ultimately responsible for ensuring the work complies with Building Regulations.
