Which? Trusted Traders is the trades-directory branch of the consumer organisation Which?. It is the most genuinely vetted scheme on this site, with an in-person endorsement assessment and a credit-status check on top of the usual identity, insurance and qualification documentation. It is also a paid-membership scheme — but the badge is doing more work than most.
Applicants undergo a multi-step endorsement process: business documentation review, financial standing checks, customer reference checks and an in-person assessment by a Which?-trained assessor. Endorsement is then granted for a defined period, with annual renewal and ongoing monitoring of customer feedback and complaints.
Endorsed traders display the Which? Trusted Traders badge. Customer reviews are collected and moderated, and complaints can escalate to Which?'s alternative-dispute-resolution service.
Endorsement is a marketing asset. The badge is unusually credible because Which? has a long-standing consumer-protection reputation, and the assessment process is genuinely more rigorous than a standard directory. Endorsed traders use the badge in materials, on vehicles and on websites, and benefit from referrals through the Which? Trusted Traders site.
Which? Trusted Traders is the unusual case of a trade directory whose marketing is largely truthful. The assessment is in person, the references are checked, the financial-standing review is real, and the badge does not appear unless the trader has earned it. This is so refreshing that many consumers, on encountering the scheme, briefly assume there must be a catch they haven't yet spotted. The catch is that it costs more — and that there are fewer endorsed traders to choose from.
Which? Trusted Traders is the closest thing the UK has to a vetted, brand-backed national trade scheme. It is genuinely useful for higher-risk or longer-running jobs where you want vetting to sit alongside reviews. The trade-off is coverage: in some trades and postcodes, the endorsed list is short. Use it as a first port of call, supplement with Checkatrade or TrustATrader where coverage is thin, and always layer trade-specific regulator checks (Gas Safe, NICEIC, etc.) on top.

Yes — an assessment cost and an annual fee. The methodology and outcomes are independent; the funding model is paid.
Which? offers an alternative dispute resolution route as part of the scheme.
The endorsement process is more rigorous and costlier, which results in a smaller, more curated pool.
