Federation of Master Builders

What Federation of Master Builders does

The Federation of Master Builders (FMB) is the UK's largest trade association for the construction industry, founded in 1941 and led by CEO Brian Berry. It serves small and medium-sized builders, sole traders, and a network of associate (supplier) members across the United Kingdom, with an 11–50 employee operating footprint. The FMB's core offering is a subscription-based membership (around £62.69 per month plus VAT) that bundles a vetted Find a Builder directory, dispute-resolution services, insurance-backed guarantees, member helplines, legal and contractual templates, and a Business Resilience Hub.

Its commercial engine combines membership subscriptions, associate-member fees, advertising and sponsorship through Master Builder Magazine and its podcast slate (Build Up Podcast, From the Basement), flagship events such as the Master Builder Awards and the annual National Conference, and increasingly training revenue via the Build Academy initiative with the CITB. The FMB also operates a long-running Primary Authority Partnership with Hertfordshire Trading Standards and a sustained advocacy campaign pushing for mandatory licensing of UK construction firms, positioning its vetting standard as a potential regulatory benchmark. Geographic reach is UK-wide, with no disclosed international operations.

A complementary Find a Builder online directory connects vetted members with UK homeowners seeking building work.

Direct peers

• Checkatrade: Consumer-facing vetted-trades directory. Competes directly with FMB's "Find a Builder" directory on homeowner discovery of vetted builders, with a broader trade scope and strong consumer brand.
• Federation of Small Businesses (FSB): UK membership body for small businesses across sectors, including construction. Competes for the same SME segment on subscriptions, advice helplines, and advocacy - same GTM playbook, broader vertical focus.
• NHBC (National House Building Council): UK's leading new-home warranty and quality assurance provider. Operates in the same construction quality-vetting space, particularly for residential builds, and is closely aligned with FMB's inspection and consumer-protection remit.
• National Federation of Builders: UK trade association representing construction contractors and specialists, with similar SME-builder membership model, advocacy remit, and regional branch structure. Most direct peer for FMB's core member constituency.
• TrustMark: Government-endorsed quality scheme for tradespeople. FMB is already a Scheme Provider for TrustMark, creating direct overlap on quality-vetted builder status and competition for consumer trust signals.
• Which? Trusted Traders: Consumer-protection brand endorsement scheme from Which? for vetted tradespeople. Competes with FMB's Find a Builder on consumer-facing trust signals, leveraging Which?'s stronger consumer brand recognition.

Broad incumbents

• Chartered Institute of Building (CIOB): Larger chartered body for construction professionals and managers. Overlaps with FMB on training/credentialing and policy advocacy, but serves individuals and corporate members across the broader construction profession.
• Home Builders Federation (HBF): UK trade association for larger-volume housebuilders. Operates in the same residential construction advocacy space but represents the opposite end of the SME-vs-large-builder spectrum from FMB.

Emerging players

• Rated People: Online marketplace connecting homeowners with tradespeople. Partial overlap with FMB's directory offering - more transactional lead-generation model versus FMB's vetting-led trust model.

Regional players

• Scottish Building Federation: Regional trade body equivalent to FMB for Scotland, representing SME builders with the same vetting, advocacy, and member-services structure but limited to a single UK nation.
