20,000-cycle endurance test for “whole of life” performance

The British Board of Agrément (BBA) is the UK’s major authority offering approval and certification services to manufacturers and installers alike. They make sure we do as we claim, so you can rest assured knowing someone else is looking out for your interests.

BBA Approval is recognised by building control, government departments, architects, local authorities, specifiers and industry insurers like the NHBC. Because our manufacturing facility is BBA certified, you can be confident that every window we make, meets the highest standard.

Performance quaranteed

The BBA was set up on behalf of the Department for Communities and Local Government to provide independent testing. This validates claims made by manufacturers that their products conform to regulations and perform as expected. NHBC generally requires BBA certification for new build.

BBA Certificates have been providing authoritative and independent information on the performance of building products for over 35 years. Every Agrément Certificate contains important data on durability, installation and compliance with Building Regulations.

Complete approval

We are the only window company to exceed the BBA’s 20,000-cycle endurance testing for “whole of life” sash windows. This is an onerous test designed to recreate a 20-year lifetime of a product.

Our product range is fully BBA approved. That includes components, balances, hardware; even the Georgian bars get a BBA certificate for the sealed units’ lifetime.
