Only in existence to please their paymasters, they have absolutely no care for customers or that a company is not compliant with building regulations.
I have a FENSA useless certificate that allegedly covers me against failures to follow building regulations (this is a self certified inspection by the installer….that’s a laugh) so, even though I have an independent report from RISA that states the windows are not compliant with building regulations, FENSA refuses to follow this up with Anglian windows, their reasoning is: That I am not interested in allowing Anglian to return and make an even bigger mess of the install.
FENSA is a government backed CPS scheme and should be in existence to protect customers and to ensure the installation companies maintain FENSA’s high standards. This is only true if you allow the company to have an opportunity to make an even bigger mess than they’ve done already.
Compliance with building regulations is second fiddle to allowing cowboy companies to wreck your house even more than they’ve done so already.
FENSA will come up with any excuse possible so that they avoid having to contact their paymasters (members) - Customers are unimportant to them as we don’t pay their wages…..TOTAL WASTE OF TIME.

Antwoord van FENSA Limited
I spoke with the most lovely woman today. She was fun, kind and extremely helpful. Her generosity in helping me locate my lost Fensa certificate was above and beyond. A joy to speak to her. Be kindly always to those that are trying to help wherever they can. Thank you very much Heather for making things better for a stupid man....A joke....Take care
Never received my certificate, chased my installer multiple times. When I contacted Fensa they told me it was £25 for a duplicate. Poor experience.
Having had some new double glazed windows installed we took up the offer of a “free FENSA inspection”. Inspector turned up and said we were none compliant with the building regs as windows weren’t vented. I told him that we had only had 20% of windows changed and vents were not necessary. He poo pooed this and reported it as a none compliance and said my installers would need to put in vents. I would not let the installers drill my new windows so then got a threat from FENSA of sending in the Council Building Inspector (at a cost to me).
When I argued with FENSA HQ that I had changed less than the 30% of windows referred to in the Building Regs they agreed with me and admitted that their inspector was wrong.
All in all a lot of my wasted time and very unprofessional inspector.
My learning from this is; never invite inspectors round to your house!
FENSA don't do anything on the inspection other than check the glass with a device, does it have a safety and fire bracket. FENSA don't check the size, fitting quality and help to stop any potential damp issues.
I was told they would report an issues to the window company and they would reinspect but not heard anything for months.
Don't trust the recommendations if you are planning to upgrade. FENSA certificate is not worth the paper it's printed on.
I contacted FENSA Spoke to a lovely Gentleman by the name of Stephen Gambrell.All my issues was listened to and dealt with promptly without any problems. I found him very helpful indeed and very informative. Wish there was more people like him out there when dealing with a company.
Many thanks again Mr Gambrell job well done very much appreciated.

Astonishing efficient retrieval of certificates from 10 years ago, emailed through within 5 minutes. Thank you Heather!!
What a pig headed company. Assume complaints is a complaint against a window company and not against FENSA. No phone no for this helpful Heather that other people have found or anyone else for that matter to help people having difficulties ordering certificates.- only an email link which I hope they use if someone on their staff needs an ambulance.
Sounds like Heather is very helpful when dishing out FENSA certificates - wait till they need to make a claim - that's where the problems in customer service arise
Although problem not fully resolved they were very quick in helping me as much as possible and very polite.
Heather was amazing..... helpful is an understatement.
Within 1 hour we had the certificate.
Thank you so much
I had trouble navigating the online form to order replacement certificates for double glazing. I rang to ask for help and a delightful lady, Heather, took the whole thing out of my hands and manually entered my information and took payment. Within five minutes the certificates had been emailed to me. What fantastic service and what a lovely lady.
Extremely efficient service from Heather for replacement FENSA cert.
Responded to my email enquiry promptly and then organised my replacement certificate in no time at all.
Thank you Heather.
Needed a replacement certificate for work done in 2009, certificate lost. It took about two minutes online and then I received the certificate by email immediately. Very impressed, thank you Fensa.
Was kept informed when I had to wait in a short queue only waiting for few minutes. Fensa’s staff were helpful, efficient and the problem was quickly dealt with successfully
I urgently needed a copy of my Fensa certificate in order to comply with my solicitors request whilst selling my house. Spoke to a wonderfully efficient lady called
Heather Parker. She had it sorted, paid for and emailed off to my solicitor before you could say Boo!!!! Wonderful Service, great customer relations and a credit to your company! Top Marks!
Thank you Heather Gibson Parker for having the patience, professionalism and kindness to fully explain the issues of trickle vents in a Conservation Area.
You have been amazing and FENSA are lucky to have you..
Watch out for the Magpie!!
Fensa is a waste of time , my builders didn’t fit my doors correctly and refused to acknowledge this , so I had an independent report carried out by Risa , this showed all the errors and what needed correcting. The builders stopped answering my calls so as they are Fensa registered I reached out to Fensa , they have no phone number so by email only. I was then told by fensa they couldn't help me as I didn’t have a certificate. Exactly, this is part of the problem, I needed their help to resolve this did just got fobbed off. The builder wins every time . !!!
Fends have not updated the changed local authority codes since April when several authorities merged. Local authority changes were planned years ahead what were they not ready? I have lost a house sale and they do not seem interested. Their lack of progress has cost me more than the window installation.
Spoke to a lovely lady as my cert was incorrect from my window company. The lady sorted it all out very quickly. Very impressed with their efficiency
