Installer Information

The Thermal Rating Register can certify the thermal performance of your window products for Building Regulation compliance. The Thermal Rating Register is part of Certass Limited, as such; we provide a cost effective, streamlined alternative to existing 'Window Energy Rating' registration services.

Windows registered with us will receive an A-C rating and we provide you with certificates of compliance. In addition your services will be listed on our website as conforming to Building Regulations; consumers are able to search local installers by window rating, and framing material.

Becoming a TRR Accredited Installer© not only allows you to demonstrate Building Regulation compliance but also provides marketing advantage. Consumers are becoming more aware of energy savings and are familiar with the A-G rating already in place on white goods. Using a Window Energy Rating gives you a marketing edge, and can help differentiate product lines based on rating; 'A' rated windows are usually sold at a premium price.

If you are already a Certass member the Thermal Rating Register is operated by Certass staff you already know and trust our tightly integrated service allows us to offer Certass member's significant savings over other Window Energy Rating services.

Even if you are not a Certass member we offer excellent customer service and cost savings.
