FENSA stands for
the Fenestration Self-Assessment Scheme. It has been set up by the Glass
and Glazing Federation (GGF), with Government approval, in response to
the new Building Regulations for England and Wales.
From 1 April 2002, all replacement glazing in dwellings will come within
the scope of the Building Regulations. From then on, anyone who installs
replacement windows or doors will have to comply with improved thermal
performance standards.
When having their windows and doors replaced from this date homeowners
must ensure that they get a certificate from Local Authority Building
Control or have the work completed by a FENSA Registered Company. One
of the main reasons for this change to the Building Regulations is the
need to reduce energy loss.
