Direct Answer
A UK window fitter should hold FENSA Registered, CERTASS Approved and be a member of FENSA / CERTASS. Public liability insurance (typically £2M+ cover) is non-negotiable for any work in your home. TradeMatch verifies every one of these before the window fitter can accept work on the platform. Where a body publishes a public register (e.g. FENSA / CERTASS), TradeMatch links directly to it from the trade's profile so you can independently confirm.

Window Fitters vetted against UK accreditation bodies
Every tradesperson is verified against the UK accreditation bodies that matter for the work — before they can quote.
Three Things That Matter
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.
Escrow Protection
