How Compare Builders works
Three simple steps. Two minutes to submit your project. One trusted builder — never a flood of cold calls.
Tell us about your project
Trade, postcode, rough budget, timeline, readiness. Two minutes — no sign-up wall, no contact details until the end.
One verified builder bids
We send your brief to a shortlist of Verified Premium builders. They submit sealed bids; the winner gets exclusive access — no race to be first to call.
Pick with confidence
Review the builder's portfolio, ratings and references. Verification number is publicly addressable — anyone can independently check their status.

Most platforms measure visibility, not credibility. Pay-to-list directories favour spend, while review marketplaces favour volume. Both can be manipulated.

Why both sides win
The category problem in a sentence: Checkatrade is a directory, Bark is a lottery. We're the curated marketplace that does the heavy lifting on trust so you don't have to.
Verified builders only
Each one passed our eight-stage accreditation. Annual re-verification keeps it honest.
Free for homeowners
Always. We make money from builders winning leads, not from you submitting them.
Reviews are real
Every review on a Verified Premium profile is from a completed job, contacted by our verification team.
