Certass are a UKAS accredited certification body for building regulations and energy efficient measures as well as being a Trustmark scheme operator. Established in 2006 Certass is a Government approved Competent Person Scheme (CPS). Members of Certass are CQ Assured providing consumer protection for workmanship against industry standards. The Thermal Rating Register certifies thermal performance of windows and doors for building regulations.
The Certass scheme offers protection to homeowners for poor quality workmanship and that the windows and doors provide the level of energy efficiency that the manufacture claims. Benefits of using a Certass member include a 10 year installation guarantee and deposit protection.
Certass (Certification and Self Assessment) has grown in popularity in recent years and is an alternative to FENSA in the windows industry. Since 2002 it has been mandatory for windows in homes to be issued with a certificate. Using a Certass member means they can self certify the work carried out and register the work with relevant Local Authorities.
