The Federation of Master Builders

Join the FMB

Apply to become a Master Builder to access advice helplines, guidance documents and member resources to help get your business back on track at this difficult time.

The Federation of Master Builders (FMB) is the UK’s largest trade association for the construction industry. Since the FMB was established in 1941, we have been working hard to promote, support and represent small-to-medium builders - including sole contractors - and to champion continuous improvement in building standards.

We're more than just a job listing site; all of our members are professionally vetted and independently inspected on joining to ensure they rank amongst Britain's best builders. See our membership criteria for more information.

From lobbying for members’ interests to connecting homeowners with local Master Builders through marketing activities — we’re here to help you promote, protect and grow your business. We are also a not-for-profit organisation, which means every penny of your membership is re-invested into supporting and promoting you. 

Through the FMB consumers can find peace of mind in the knowledge that their building project is in safe hands - so, are you up for the challenge?

Benefits of FMB Membership include:


The ability to display the FMB logo enhances your credibility and helps you stand out from the competition. This shows consumers that you are a quality firm they can trust.

Exclusive member discounts and promotions

Business Protection

We offer business protection tools to help you in times of need, including contracts for use with clients and a mediation service to help you put things right when disagreements arise. 

A voice in government

The FMB was established to provide a voice for construction SMEs to policymakers and this is still a big part of what we do.

Here's what our members say:

“The FMB was the best option for my company. It enables more potential clients to connect with us through the Find a Builder service and it also helps our clients to feel at ease. When they see the FMB badge they know that it’s a sign of quality and that we have been vetted and checked by an independent body.”

Steve, FMB Member, Leicester

“The training opportunities that the FMB offer are fantastic. They have helped us and our team to develop our skills to take our business forward and to be bigger and better in the future. The fact that we also get job leads along the way is just an added bonus!”

Sarah, FMB Member, Nottingham
