Installers of windows and doors can join Assure, an official Competent Persons Scheme, to self-certify window and door installations, instead of applying for Building Regulations approval for each individual installation.

Assure benefits everybody in the supply chain: fabricators, installers and homeowners.

Amongst other benefits, Assure-certified installers can access additional training while also proving the quality and energy efficiency of their work. Meanwhile, homeowners can be certain that their installation complies with Building Regulations, meets the specified energy rating and is covered by an insurance backed guarantee.

As an official certification body, Assure can also provide a host of other services for professional installers including help and support with energy rating certification.
