Who you're hiring

1941 founded

FMB is the most consumer-recognised builder badge. Customers shortlist on it.

The Federation of Master Builders has been the UK's largest construction trade association since 1941. Members are vetted by independent inspection. The badge is what nervous homeowners use to whittle down a longlist of builders to the three they'll get quotes from.

Most builder sites bury it in the footer. We put it in the hero, next to your TrustMark, your insurance figure, and any NHBC warranty status. The customer making a £25,000 decision picks the builder whose credentials are obvious.

The maths

If one extension lead lands a year at £8,000 margin, what's that worth across a decade of better local SEO?

Builders deal in £20k to £100k jobs. One extra lead per year covers a lifetime of Growth subscription. See what's in Growth.

Built for builders

What you get from a site built specifically for builder work.

01

Portfolio that closes, not a contact form that doesn't

Builder leads convert on photos. Before-and-afters per project type: extensions, lofts, renovations. Indexed for Google so each one ranks for "extension builder [town]."

02

FMB and TrustMark surfaced together

Customers shortlisting builders look for both badges. We put them in the hero with your insurance figure beside them. The shortlist becomes the call list.

03

Quote pages built for £25k+ decisions

A £25,000 extension isn't a "request a quote" button decision. We build a structured project enquiry page (rooms, scope, planning status, photos upload) that captures qualified leads, not tyre-kickers.

04

Found for "extension builder [town]"

Local SEO targeting the searches that produce shortlisted leads. Postcode coverage. LocalBusiness schema. Google Business Profile management on Growth.

Qualifications & trust signals

The badges UK building customers actually look for.

FMB is the recognisable badge. TrustMark is the government stamp. NHBC matters for new-build. Insurance figures matter most of all. We feature whichever you hold.

Questions builders ask us

Common questions, plain answers.

Do photos really matter that much for a builder website?
More than anywhere else in the trades. Customers buying £25k+ extensions decide on portfolio before they decide on price. We build a proper photo gallery indexed by project type: extensions, lofts, renovations, each one optimised for its own search.
Will the site work for new-build housing?
Yes. If you're NHBC-registered we surface the Buildmark warranty status prominently and link the public NHBC register. Without NHBC, most new-build sales fall through at mortgage stage, the badge does real selling work.
How do you handle quote requests for £50k jobs?
We build a structured project enquiry form (rooms, scope, planning status, budget range, photo upload) rather than a generic contact form. Pre-qualifies the lead so you're not spending Saturdays on tyre-kicker site visits.
I work alongside other trades. Can the site reference them?
Yes. We link to our roofer, electrician, plumber, and paving pages where relevant. Customers like seeing a coordinated team.
How fast can the site go live?
Seven days from the discovery call. Once we have your FMB number, accreditations, service area, and a folder of portfolio photos, we can usually get a first build over within 4 to 5 days.
