We are also registered with CERTASS and IWA which means you’ll get complete peace of mind throughout your installation.

What is Certass and what does it cover?

Certass is a UKAS approved certification scheme that checks individual contractors and companies competence against set standards.

What protection does IWA give me?

Let’s say you paid a deposit to secure home improvement work. Then the worst happened – for whatever reason the trader ceases trading before starting the work. The good news is that at St. Clement Double Glazing, we are registered with IWA who will protect that deposit and will arrange the completion of your contract or refund your deposit.
