TrustMark (TrustMark)
Government-endorsed quality scheme covering 90+ trades. Last reviewed April 2026 by the TradeMatch editorial team.
TrustMark is the only government-endorsed quality scheme that covers tradespeople working in or around the home. It is operated by an industry-government body and accredits scheme operators across 90+ trades — building, decorating, gardening, glazing, heating, roofing and more. A TrustMark-registered trader has agreed to a code of conduct, a customer-charter, and complies with technical standards set by the relevant accreditation body. Crucially, TrustMark requires Insurance-Backed Guarantees (IBGs) for any deposit-protected work, meaning the warranty survives even if the trader ceases trading.

What does TrustMark cover?
TrustMark itself does not directly certify individuals — it endorses scheme operators (FMB, NICEIC, Gas Safe, MCS and others) who in turn vet their members. The scheme covers home repair, maintenance and improvement work but excludes building-control-only items like structural-survey work (RICS) or pure architectural design (ARB). TrustMark also operates the Retrofit scheme (TrustMark for Retrofit) which accredits installers under the PAS 2035 retrofit standard — relevant for grant-funded energy efficiency work.

TrustMark FAQ
Is TrustMark the same as a trade body?
No. TrustMark is a government-endorsed umbrella scheme that accredits scheme operators (such as FMB, NICEIC and Gas Safe). Each operator vets its own members. TrustMark adds a consistent code of conduct and consumer-protection layer over those operators.
What protection does TrustMark offer?
A formal Code of Conduct, a complaints route via the scheme operator, mandatory Insurance-Backed Guarantees on deposit work, and access to the TrustMark dispute team. Critically, the IBG means your warranty survives if the trader ceases trading.
Are TrustMark traders more expensive?
Marginally — accreditation has cost. But on a £5,000+ job, the IBG protection alone tends to be worth more than the price difference. For small jobs (sub-£500), TrustMark is less of a deciding factor; for any major work, it is one of the strongest UK consumer protections you can ask for.
Does TrustMark replace my Gas Safe / NICEIC check?
No. TrustMark sits on top of those legally-required schemes. You still need a Gas Safe engineer for gas, NICEIC/NAPIT for electrics. TrustMark adds the consumer-protection wrapper over those technical certifications.
Why TrustMark verification matters before any deposit
Lapsed accreditations are the most common silent failure on UK trade hires — registrations expire annually and not every trader updates their listing. Always verify the TrustMark number on the public register on the day you sign, not at first meeting. On TradeMatch, every TrustMark-registered tradesperson is independently re-checked before they can quote on your job, and the registration link is shown on their profile so you can confirm yourself.
