Certass is a Competent Person Scheme. CPS were introduced by the Government to allow individuals and enterprises to self-certify that their work complies with building regulations, as and alternative to submitting a building notice or using an approved inspector. Certass covers the installation of replacement windows, doors, and associated glazing products in domestic properties, and is licensed by the Department for Communities and Local Government. All Certass members are checked in a number of ways. Their trading record and financial status is checked, along with checks that estimates are provided in plain language, and that the “14 day cooling off” legislation is adhered to. Furthermore, checks are done to ensure that the guarantee wording is fair, that a complaints handling procedure is in operation, and that sample installations are annually inspected. Finally, these checks ensure that consumers are given an insurance backed guarantee, and that window installations meet current thermal rating regulations. We are part of this scheme.
