Excellent Customer Service-FENSA Went Above and Beyond!
After four years of trying to resolve a serious issue with a FENSA-certified window installer, I had almost given up hope.
The installer had fitted one of my windows incorrectly, resulting in water leaking through and accumulating inside. Despite countless emails, phone calls, and repeated attempts to have them honor their warranty, every request was ignored. Because the installer was still trading, I couldn't claim through the warranty, and I was also unable to find anyone else willing to carry out the repair.
Fortunately, I had chosen a FENSA-certified installer. When I finally contacted FENSA for advice and assistance, they acted immediately. Their customer service was exceptional from start to finish. They persistently followed up with the installer until the issue was finally resolved, and they kept me informed every step of the way, regularly checking in to make sure everything was progressing and that I was satisfied with the outcome.
A special thank you to Jack Flowers, who handled my case with outstanding professionalism, persistence, and genuine care. His attention to detail and commitment to seeing this through made all the difference. After four years of getting nowhere on my own, he succeeded in helping me achieve a resolution.
I can honestly say this would not have been resolved without FENSA's support. Their dedication to helping consumers and their exceptional customer service deserve the highest praise. Thank you, Jack, and thank you to the entire FENSA team.

FENSA you are outstanding!
I first contacted FENSA at the end of May 2026, when we urgently needed to become FENSA registered in order to submit a tender due on 19th June. Time was extremely tight, but from the outset Alistair pulled out every stop to make it happen for us.
He worked tirelessly throughout the process and especially on the day before our submission deadline to push everything through. Thanks to his efforts, we received our certificate on 18 June at 17:15 just in time to submit our bid on the Friday morning.
Without Alistair, we simply wouldn't have passed our assessment and registered in time, and we'd have missed the tender altogether. He went above and beyond at a critical moment for our business, and his professionalism, and sheer determination made all the difference. A genuine credit to FENSA.
A quick mention too for his colleague Beryl, who was equally helpful and a pleasure to deal with.

easy process via website
The process of going on your website, and then contacting you via that was very easy. I received a message stating when i would receive contact and then Jennifer sorted out a new certificate very quickly.
My only slight issue is that it took just over 1 month to receive the certificate. this seems like a very long time for such a simple certificate, but we were told to expect something in 10 working days - this is clearly not correct so a more realistic timescale would help to set expectations more accurately.

Simple as this
²Simple as this, my FENSA Certificate isnt worth a thing. After multiple contact and getting nowhere I got told the inadequate expensive work I had done is out of scope apparently. So not covered at all. Had another email, yet again telling me that my issue isn't covered. So I say it again ,why give anyone a fensa certificate. I was deluded enough to think a inadequate job was covered. Its not, I have now told Mr Gallespy to contact me with his crap no further. I sincerely always thought your certificate was your peace of mind. It would almost be funny if I wasnt so angry. Never mind if your job was done to satisfaction your safe. Because you dont need your certificate. I mean if your not covered for bad installation its laughable. Your not , you have a window or door fitted thats got gaps for eg. Your not covered. As for the reply below, theres absolutely no point engaging. Why should this time be any different.

We’re sorry to hear about your experience and appreciate your feedback.
A FENSA certificate confirms compliance with Building Regulations but does not cover all aspects of installation or workmanship, and some matters may fall outside of scheme scope.
If you would be so kind to respond to the information request I would be review your case and speak with you
