A bit about the British Board of Agrément (BBA)

Agrément Certificates are the Gold Standard of product or system approvals: a rigorous and thorough examination of the product, its manufacture and installation – much more than a simple statement at one point of time.  Agrément Certificate holders are subject to production surveillance throughout the life of their Certificate and you can always be sure that you will get the BBA-agreed specification of product.

BBA approval is an independent technical approval accepted by the NHBC, building control officers, architects, engineers and surveyors nationwide.

Rytons is proud to have the largest range of natural ventilation products of any UK ventilation manufacturer.  The BBA symbol and certificate number is displayed next to each approved product on our technical data sheets and product guides.
