Certass is really a not-for-profit organisation created in 2006 to enhance standards within the double glazed industry and offers a method which enables approved companies to self-approve installations. What this means is, the Member company won’t have to submit a building notice or make use of an approved inspector, every time they install home windows, doorways or conservatories to adhere to building rules, costing you less along the way.

Certass is licensed through the Department for Communities and Local Government to Certify that approve installaters of double glazed items in your home adhere to current rules.

Prior to becoming Members, all applicants are evaluated by Certass to make sure their double glazed work meets United kingdom building regulations. After a Member completes an installation, Certass notifies the local Building Regulations authority who will issue a Building Regulation Compliance certificate for that homeowner to make use of later on and may provide value along the way of promoting your home if selling.
