CERTASSCERTASS Approved Member

Certass, is a Competent Person Scheme covering the installation of replacement windows, doors and associated glazing products in domestic properties, and is licensed by the Department for Communities and Local Government. Certass was established in 2006 and is dedicated to raising standards in the glazing industry. Membership of Certass enables contractors to self-certify installations as an alternative to submitting a building notice or using a local authority approved inspector.

In simple terms, this means that Certass financially and technically assesses its members to ensure they meet current UK building regulations. Once an installation is complete, Certass notifies the local authority and the Building Regulation Compliance Certificate is issued to the homeowner.

All Certass members are checked for the following:

  • Trading record and financial status
  • Estimates are provided in plain language and Guarantee wording is fair.
  • Consumers are given or offered an insurance backed guarantee and Adherance to the "7 day cooling off" legislation.
  • A complaints handling procedure is in operation.
  • Sample installations are annually inspected and Window installations meet current thermal rating regulations.

The Thermal Rating Register, also managed by Certass, ensures thermal compliance of replacement windows and doors.

Certass and the Thermal Rating Register pride themselves on delivering a fair, friendly and cost effective service to both the industry and homeowners.
