Certass Registered Installer


CERTASS is a competent person scheme that regulates the double glazing industry. To be registered we have to demonstrate that we follow strict installation standards and building regulations and are routinely assessed and inspected on this.

The CERTASS seal of approval gives homeowners peace of mind that they are in good hands. As a certified company we give a certificate of compliance when the work has been completed meaning that you do not need to get an officer from the local authority to inspect the installation. Your certificate will be provided within 28 days of job completion.

This certificate is required when moving house. Most people are familiar with a FENSA certificate, a CERTASS certificate is completely equivalent to this and is all you will need when moving home. We simply chose to use CERTASS because of their efficiency and customer service.

"After trying to get someone local to repair our conservatory roof we found Will and his team via TrustATrader. He came in person to survey the work and discussed our options without any pressure. After we faffed about a bit in deciding what we wanted, Will agreed to remove and replace all the glazing and roof and, just as planned ,he arrived with his team and completed the job on time despite a Buxton blizzard half-way through the job! All the team were very friendly, polite and professional. The finished product has exceeded our expectations and we’re very happy with the results we just look forward to some sunny weather to enjoy our new conservatory (which feels more like an extension!) I thoroughly recommend Pristine PVC."
