Ensure replacement windows meet building regulations

Nowadays any replacement glazing, whether single or double glazed, comes within the scope of the Building Regulations, to the point where anyone who installs replacement windows or doors in domestic premises must comply with current thermal performance standards.

As the FENSA homeowner page on the FENSA website explains: “The reason for this is to reduce energy loss in line with Government policy. The Building Regulations have controlled glazing in new buildings for many years but this represents only a very small percentage of our total building stock. It is essential to improve the performance of the much larger number of existing buildings if we are to meet increasingly stringent national and global energy saving targets.”

“When the time comes to sell your property, your purchaser’s solicitors will ask for evidence that any replacement glazing installed since April 2002 complies with the Building Regulations. There are currently two ways to prove compliance:-

a certificate showing that the work has been done by an installer who is registered with FENSA or a similar body

a certificate from the Local Authority Building Control stating that the installation has been approved under the Building Regulations.”
