Certass Approved

Best Choice are Certass Approved installers so you can rest assured that you are getting a professional and approved double glazing window installation with a 10 year guarantee.

Certass stands for Certification and Assessment and is one of the Government licensed Competent Person Schemes. Since April 2002 it has been a legal requirement that all domestic replacement window and/or door installations are registered with Local Authority Building Control (LABC). Installers had to register the installation with LABC or they could self certify the installation with only one scheme available at that time.

In April 2006 the Government recognised the need that the industry required more than one scheme and two other organisations were granted licences, one of which was for Certass.

  • Certass is user friendly for both the consumer and contractors.
  • All contractors registered with Certass are required to be vetted by both Certass and their registered Insurance Provider.
  • By using a Certass registered contractor, it saves the householder having to go through their Local Authority Building Control office, which can be time consuming and expensive.
  • Certificates are issued direct to the consumer noramlly within 14 days of notification of the installation by the contractor.
