WE ARE THE SPECIALISTS IN
INSTALLER CERTIFICATION FOR THE
BUILDING FABRIC REFURBISHMENT INDUSTRY

Certass Limited is a UKAS approved certification body for the operation of a Competent Person Scheme under a Department of Communities and Local Government (DCLG) license and a Green Deal Certification Body under licence from the Department for Energy and Climate Change (DECC).

We also manage a product certification scheme called the Thermal Ratings Register, which ensures the thermal compliance of replacement windows and doors. This is an agreed standard for UK Building Regulation compliance.

We pride ourselves on delivering a fair, friendly and cost effective service to both the industry and homeowners. 

Membership of the Certass certification scheme is not automatic. Member companies are assessed inline with the standards laid down in EN17065 and specific license requirements of DCLG, TrustMark and/or DECC.

This means that Certass financially and technically assesses its members to ensure they meet required standards.

In addition to initially assessing every member each year, Certass will inspect a sample of work submitted by the member for scheme compliance. Where appropriate, Certass notifies the local authority and issues a Building Regulation Compliance Certificate to the homeowner.
