Certass Ltd Recensioni 98

I reached out to certass for advice on one of their members who had conducted work on my property last year. They were very quick to respond and incredibly helpful with the information they passed on. And I am very grateful for that!

I was looking for replacement certificates for a probate property. The general search on the Certass database showed multiple entries. I emailed the service team, and the next morning they replied with all the information. I was able to pay and have all the replacement certificates the same afternoon. The customer service was brilliant and fast. The correct certificates were found. Emails were responded to speedily. I was really impressed. Thank you so much.

I requested a CERTASS certificate through the automated system on the website. I have had to deduct a star because the system did not give me an option to choose which certificate I wanted, so I paid the £30 and recieved a previous CERTASS certificate relating to my property, rather than the most up to date one that I wanted. However, when I phoned they were very helpful and emailed the correct one straight away.

I have just had a very positive experience with Certass with regards my bifold doors installed in 2023. Jacqueline resolved my enquiry quickly and efficiently. Happy customer

Hi everyone I was a member of certass for 3 years, and I would like to let everyone that thinking of joining them to avoid them completely. All there staff are very incompetent and none of them have any experience in the glazing industry or any industry at all.
Avoid.Avoid.Avoid

I had missed our Certass guarantee documentation and yet Certass provided a replacement straight away. Superb service from Whiteny!

We have used Certass for many years. As a window and door installer we have had excellent back up from them and they always have someone friendly on hand to answer any questions.

We had missed our Certass guarantee documentation due to the fact that we did not check our e mails after having window renovations in April.
We telephoned Certass and even though we were just over 6 months deadline for a replacement certificate they kindly waivered the cost of the £30 fee. The team were extremely efficient and we were sent a replacement certificate almost immediately
after our contact.
An excellent company providing one of the best personal service we have experienced in quite some time

I've been a member of Certass the last 3 years and they have always been on hand to sort any problems I've needed help with.
Today James finner helped me out.
Cheers James.

Needed a replacement certificate but unable to do it online. Phone up and the staff sorted it out right away

We had an issue with the information that was given to Certass and needed amending. Jacqueline was most helpful and very efficient. Thank you for all your help, much appreciated.

Generally irrelevant and pointless.
Had some windows installed by somebody who was Certass not Fensa registered. I can see his registration on Certass. Certs for installation are not available via Certass as not in Database. With problems like this Certass says to contact installer which I did as I see him socially quite frequently. He says he would have registered the installation and we should have received an email confirming. He did comment that he's had this a lot with Certass. Oddly enough I can see every earlier installation with Fensa, which suggests that the Certass system is pretty pointless and no mandatory submission after installation as there is with Fensa which kind of defeats the purpose of Certass.

Update 9th Nov for those who may be in a similar predicament:
To provide a little more context. Like many people selling their house I needed the Certass window installation certificate to provide to solicitors. I had all the Fensa certs as paper copies of these had been posted to me and they're also available digitally as I can see these online anyway.
Though the installer mentions Certass 6 year compliance against building regs on his final correspondence the certs are not available via certass digital download as there is no registered installation at my address. So what value is there in the certs should the installer go out of business and certass has no knowledge of the installation?
In the end the lack of certs was causing the delay with the selling of my house and I simply didn't have time or enthusiasm to mess about sorting out the issues between certass and installer and opted for an easier route of having to pay indemnity insurance via my solicitor to cover any potential future issues with the installation.
I believe this could be avoided if it was mandatory for the certass registered installer to register the installation with certass as this provides some value.
Based on my experience I'd not regard an installer being registered with certass as having much value.

My installer did not apply for a certificate and after eight months of chasing, where the installer just ignores all correspondence from Certass and myself, Certass have said they cannot do anything. Certass has no power and could not care less about the customer and may as well not exist. Due to this I would never use a Certass approved installer again, which I am sure excludes some that are good.

I would recommend all legitimate installers move away from Certass as you are being dragged down by Certass themselves.

they send pre-loaded max score reviews for you to approve to get their BS certificate

I had new windows fitted all around my flat, done my Highview glazing and construction ltd. I was so happy. They arrived at 8am and was finished before 2.30pm.
The windows are amazing I’m so happy. The workers were polite and very tidy.
I would highly recommend

Thank you again 😊

it could not be poorer, my personal opinion, a haven for rogue traders, helping them to keep customers of their back, but hey, just my personal opinion.

We had a deeply disappointing experience with Certass, who claim to offer consumer protection and installer oversight. In our case, they did neither.

We paid over £21,000 to a Certass-accredited installer (Coulsons Conservatories, Windows and Doors Ltd) for a full-house replacement of windows and doors. The installation was severely flawed – including missing fire safety egress hinges, insufficient fixings, twisted and bowed frames, poor sealant application, no lintel support above one window and increased thermal bridging risk due to incorrect frame positioning. Trickle vents were glued in place, door sashes dropped or failed to close properly and no documentation was provided to confirm energy compliance.

Coulsons later admitted that the bifold doors they installed had no valid U-value certification, meaning they breached Building Regulations Part L. Certass had requested supporting documentation for thermal compliance, but to our knowledge, it was never supplied. Despite this, Certass took no enforcement action and ultimately closed the complaint once we refused to allow Coulsons back onto the property.

To get any response, we had to commission and pay for an independent 32-page RISA inspection report, which confirmed multiple serious breaches of Building Regulations. Certass accepted some of those findings – but only after months of chasing, missed deadlines, and repeated pressure.

Despite all of this, Certass:
• Took months to act, despite having clear evidence
• Missed or delayed replies, despite stated response timeframes
• Allowed the installer to remain listed as a “competent installer”, even after confirmed breaches
• Refused to publish our review, citing a timing technicality (submitted one day after they revoked the certificate)
• Rejected reviews that referenced Certass, despite Certass being central to the experience
• Closed the case purely because we refused to let the original installer return – after they’d already failed repeatedly

We were left to gather evidence ourselves, source replacement quotes and manage every part of the complaints process alone. Certass ultimately shielded their member and failed to protect us in any meaningful way.

To be clear – I do not believe all Certass-accredited installers are bad. There are likely many who are skilled and professional. But if something does go wrong, Certass will not support you, no matter how much evidence you have or how serious the breach. Their system appears built to protect member companies, not homeowners.

We’ve retained full documentation and have shared our experience to help others avoid going through the same.

Had Installation undertaken by a so called reg. Certass installer. Emailed them 3-4 times through their website, no response, called left a series of messages requesting a call, again no response. They do not act as a governing body or act on the behalf of consumers, in the event that some goes wrong with an installation that they will act as an intermediary, they don't. In short don't trust this organisation.

New windows and doors fitted 8 months ago.
Just having a clear out of all household documentation to realise I have no Certass certificate for work carried out.
I have fitters receipt and insurance policy ?but no certificate.
Contacted Certass who have sent a link ....£30 for duplicate is absolutely disgusting. I did not realise that you needed to download the original within 6 months .
Shocking

Unable to get the certificate for new installed windows for 6 months because their website didn't work and saying come back later!! and after this period they want additional charge 30 pounds which is ridiculous!! SCAM COMPANY AVOID !!!
