Trusted Payments is a private company endorsed by the government, not a government service, and it says itself that it isn't FCA-authorised (its payment provider and its insurer are). It works only with trades vetted through a scheme: TrustMark, the Federation of Master Builders, Book a Builder UK, Buy with Confidence, BALI or Scottish Trusted Traders. Registration is free for the trade. The homeowner pays by bank (Open Banking), not by card, and pays the fee: on 25 October 2026 the site said 1% per payment, capped at £4 (partner pages have described a project fee, so check the current figure on their site). Each stage is released to the trade at 6pm the day after the homeowner signs it off, and 10% of the price is held until the whole job is finished, snagging included. If there's a dispute, the two sides get 45 days to sort it, then the Dispute Resolution Ombudsman decides and both are bound. The homeowner gets an insurance-backed warranty of up to £20,000, 3 months during the work and up to 24 months after.
WorkPaid is open to any sole trader or limited company, vetted or not, with your accreditations shown on the quote if you have them. The customer pays from a link by card, Apple Pay, Google Pay or bank, and the money goes to your own bank account without a sign-off step, usually in about 3 working days. You pay the fee, 2.5% capped at £500 a quote, or pass it on. There's no warranty and no ombudsman: your customer has their rights under the Consumer Rights Act, and on a card payment, their bank's chargeback process.
