I don’t understand the point of this…
I don’t understand the point of this organisation. We installed the windows in Feb 2026 and used the company that had active membership with them at that time. In March we notified CERTASS that we hadn’t received the certificate. The response was that our installation was not registered. We chased both the company and CERTASS in March and April. According the their website all members need to record the installation within 21 days. In May we asked CERTASS to intervene again as our installation was still not recorded. The response was that our company doesn’t have an active membership with them any more so they couldn’t help. The advice was to contact local Council to obtain the certificate through them - additional cost of £600. We chose the installer that was CERTASS approved and had active membership on the day when installation took place and when we raised the issue in March and April.

Terrible Customer Service
For whatever reason, we never received their email containing certification for our new windows. I don't recall ever seeing their email & i have searched every email folder going (including deleted emails) and absolutely no trace of the email.
They say they issued them in June 25 & we noticed in April 26 that we hadn't received our certification. so less than a year.
They refuse to resend this without us paying a fee to retrieve our certification. And say they only give 6 months free of charge to retrieve docs.
Their customer Service was awful & they are adamant they want their petty £30 fee before they'll send us our certification.
I dealt with someone called Jaqueline & they really weren't very nice to deal with. She went over & beyond to prove that they'd sent email & had no interest in helping.

Hi Jamie,
We're sorry to hear you're disappointed with your experience, and we completely understand how frustrating it is when an important document can't be located.
Our records show that your Building Regulation Compliance Certificate was issued and sent to the email address provided at the time of registration. As with all certificates, we offer a six-month period during which they can be reissued free of charge. After this period, requests for replacement certificates are subject to our standard administrative fee, which is applied consistently to all customers.
We appreciate that this wasn't the outcome you were hoping for. Throughout our correspondence, our team provided the information available to us, including evidence that the certificate had been issued, and explained the replacement process in line with our published policy. We're sorry if this came across as unhelpful, as that was certainly never our intention.
Thank you for taking the time to share your feedback.
Best wishes,
The Certass Customer Experience Team

I requested a duplicate certificate from Certass - whilst they couldn't find any record of it (which was disappointing) their Customer Experience team responded to my questions really quickly and were very helpful (when they didn't need to be). It was quite refreshing to receive such a prompt and thorough response. Thank you

I received a certificate saying my new Windows had been installed in line with building regulations. I had experienced cold walls and cold air ingress since the Windows were fitted. When the installer took the trim off of the window sill I could see there was an unsealed gap between the new window and the wall which was unsealed. It was obvious this was causing the issues. Also the new balcony door was jammed into a worn timber base causing air leaks there. Certass were not willing to investigate without photographic evidence. This was not possible without taking the trim off again. The complaints system is loaded in favour of the installer and I have a meaningless certificate. The burden of proof should be On the installer to prove they have complied, not On the homeowner to be set unreasonable and impossible evidence demands

Hi David,
We’re sorry to hear that you remain unhappy with the outcome of your complaint.
Certass operates an evidence-based complaints process and can only investigate matters that fall within the scope of our government-authorised Competent Person Scheme. Our remit is limited to assessing compliance with Building Regulations for work that is permitted under our licence.
In order to review concerns about an installation, we require supporting evidence (such as photographs or inspection findings) so that our technical team can determine whether there has been a breach of Building Regulations within that scope. Without evidence, we are unable to progress a formal investigation.
In your case, the installer engaged with the process and provided information for assessment. Based on the evidence available and within the limits of our licensed remit, no breach of Building Regulations was identified and the complaint was closed accordingly.
If any aspect of the work falls outside the scope of our scheme, this would need to be pursued through the appropriate alternative routes (such as Building Control or other regulatory channels), as Certass can only act within the authority granted under our licence.
If further supporting information becomes available, you are welcome to submit it and we will review it in line with our procedures.
Best wishes,
The Certass Customer Experience Team
Quick response and issue of certificate
Very helpful in confirming the window installer hadn't submitted the necessary paperwork, copying in the installer in their response to me which prompted the installer to take immediate action.
The certificate was then issued immediately on receipt of the paperwork from the installer. 5 star service from CERTASS
