Builders vetted against UK accreditation bodies
Every tradesperson is verified against the UK accreditation bodies that matter for the work — before they can quote.
When you read the answer above, watch for these three things
- Verified qualifications — accept platform claims only when backed by a public register link to the issuing body.
- Money-held-until-sign-off — escrow is the difference between recoverable and unrecoverable spend. Open directories don't offer it.
- Reviews tied to completed jobs — anonymous open-review platforms drift. Verified-job-only reviews don't.
