Double Glazing Installers Questions and Answers for Harrow Residents:


Do Double Glazing Installers need to be FENSA registered to fit windows?

Anyone can fit windows, you don’t need to be Fensa registered, although that is what a lot of people are led to believe. Being Fensa registered simply means you can self-certify your own work, if you aren’t registered you must get the building officer to inspect and certify the work.


If a Double Glazing installer gives me a FENSA certificate, is this a guarantee?

With a FENSA fitter, you get the option of a 5–10-year insurance backed guarantee on every installation. That means even if the installation company ceases to trade, the policy underwriters will consider claims under the terms of the original guarantee for the remaining period.


Can you sell your house without a FENSA certificate?

Yes, however windows that have been replaced since 1st April 2002 must be supported by a FENSA certificate or a building regulations certificate, to show that they legally comply.


How long does it take a Double Glazing installer to remove and fit a window?

Replacing one window takes around forty to seventy minutes per window. The typical timeline for window replacement takes around four to seven weeks after the windows are ordered. Most companies can install between ten to fifteen windows per day in your home
