The Federation of Master Builders (FMB) is the UK’s largest trade association for the construction industry. We have a proud history of supporting and promoting small and medium-sized building companies – including sole traders – across England, Northern Ireland, Scotland, and Wales, since we were established in 1941.

We are champions of quality construction work and we advocate for continuous improvement in building standards. Before they can join the FMB, our members must go through a strict vetting process and independent inspection of their work, to ensure they meet the high standards expected of a Master Builder company. Not all builders pass the test.  

We provide a wide range of business support services to help Master Builders to promote, protect and grow their business. We connect clients with professional, local builders they can trust. We build better as an industry through collaboration with government and industry partners.

We are a not-for-profit organisation run by members for members, which means membership fees are re-invested into supporting and promoting Master Builders.
