As of January 2013 NHBC require all Dormers and Chimneys to be tested and certified by a recognised organisation /body.


From January 2013, ensure that GRP Dormers and Chimneys have a third party assessment or CGMA certification. If you currently use GRP Dormer and Chimneys, check with you suppliers to see if they have third party assessment or are CGMA members who are putting their products through the testing regime.

Premier Building Products are able to supply you with CGMA certificated GRP Dormers and Chimneys through their supply chain.
