Best card machine for Plumbers and heating engineers
The best card reader for a UK plumber in 2026 is Tap to Pay on iPhone or SumUp Solo: zero hardware, no contract, and payment taken at the door the moment the job is signed off. Typical plumber card payments run £90 to £2,500 across emergency callouts and bathroom installs, with emergency work skewing toward immediate same-visit payment. The no-contract, pay-as-you-go acquirers fit a mobile sole-trade better than a fixed Dojo contract, and a pay-by-link covers larger jobs the customer prefers to pay later.
Our pick
Tap to Pay on iPhone
Acquirer: SumUp or Square
Emergency callouts reward instant doorstep payment with no hardware to forget. No-contract acquirers suit the lumpy, one-person cashflow. Pay-by-link handles staged or larger bathroom-install balances.
Why this trade matters
- Cashflow shape
- Mixed: frequent small emergency callouts plus occasional large installs. Winter burst-pipe and heating-failure peaks.
- Average transaction
- £90 to £2,500
- Contactless share
- ~45%
Watch outs
- Emergency-callout customers expect to pay on the spot; carry a charged device.
- Larger install balances may need 3DS via pay-by-link.
- Avoid fixed monthly contracts for a single-van trade.
Alternatives
- SumUp Solo (free 4G SIM)
- Zettle Reader 2
- Square Reader
