The best UK card machine for builders and tradespeople in 2026 is Pay-by-link + Tap to Pay on iPhone, on SumUp, Square or Stripe. Staged-payment, invoice-led cashflow is best served by a pay-by-link (Stripe or SumUp) for balances plus no-hardware Tap to Pay for on-site deposits and smaller jobs. A fixed terminal contract rarely pays off for a trade that mixes large bank-transfer balances with occasional card deposits. Typical builders and tradespeople card payments run £200 to £10,000+ (deposits and smaller jobs on card) per transaction with ~30% (larger balances go pay-by-link or transfer) contactless. Staged and invoice-led. Large balances often by bank transfer; cards used for deposits, snagging and smaller jobs. Lumpy across the year. Alternatives that fit lower-volume builders and tradespeople: SumUp Solo; Square Reader; Stripe pay-by-link.

How we rank

Rankings are built by desk research from each provider's published rates, upfront costs, contract lengths and settlement terms, held in a dated record per terminal (last-reviewed date shown on this page) and re-checked when published pricing changes. We do not hands-on test every device; specs are taken from provider documentation and cited. No provider pays for inclusion or position. MerchantHQ is an introducer: acquirers, including some brands ranked here, pay us commission on completed introductions. Commission never affects a ranking. See our methodology and how we are funded.

Sign through us, get all of this

Named UK account team for the life of the agreement. Acquirer pays our commission on completed introductions, so it costs you nothing on top.

24/7 dedicated support
Direct line to a named UK account manager, not a generic acquirer helpline. When your terminal goes down on a Saturday night you call us.
Quarterly rate reviews
As your card volume grows your rate should drop. We renegotiate against the 40+ UK acquirer panel every quarter, so you never overpay because you forgot to ask.
Chargeback and dispute help
UK chargeback fees vary by acquirer and are set out in your merchant agreement, and many disputes are friendly fraud that can be defended with the right evidence. We draft the response and escalate where the acquirer drags its feet.
Switching support when you outgrow
If a better acquirer fit emerges as you grow we manage the cutover. No exit-fee surprises, no dual-running gap. Same account team across acquirers.
