Outstanding support from FENSA
My complaint was escalated to FENSA after discovering our window installation wasn’t to regulation. From the outset, our case handler, Adrian, was exceptional. He was easy to reach, responded promptly to calls and emails, and kept us updated at every stage.
Adrian truly fought our case. Thanks to his persistence, we reached a solution with the window company, finally got the installation completed after eight months of delays, and avoided court action altogether. We cannot thank Adrian enough and his dedication made all the difference! Highly recommend FENSA, especially Adrian!

No Benefit to Using a FENSA Registered Fitter
I am facing the prospect of a £250 bill from building control to certify my windows as complying with building regulations. This is despite having chosen a fitter via the FENSA website who was registered with FENSA at the time of installation but recently left and registered with another competent person register. FENSA will not certify my windows, despite the fact that the fitter was registered with FENSA at the time. I cannot see what benefit choosing a FENSA registered trader has provided me - I could have chosen one who was not and registered the windows with building control myself!
I submitted a complaint to their complaints email and have received no reply.
I refer you to their website as a reminder of the promise they offer and have failed to uphold.
ENJOY PEACE OF MIND
We'll register your job for you
Did you know it's your responsibility to register replacement window and door installations with your local council?
BUT... if you choose a FENSA Approved Installer we'll do this for you!

Dear Jennifer Mitchell,
Thank you for taking the time to share your experience. We’re very sorry to hear about the situation you’ve found yourself in and appreciate how frustrating this must be.
We do understand your concerns. FENSA is only able to register installations that are formally notified by an installer while they are still an active member of the scheme. Unfortunately, we do not have a record of your installation being submitted before the installer left FENSA.
In situations like this, certification would need to be obtained through your local authority’s Building Control department, who can guide you on the next steps.
We appreciate this is not the outcome you were expecting, and we’re sorry for the disappointment caused. Please be assured that your comments have been shared with our complaints team for further review.
Warm regards
