Best card machine for Gas engineers
The best card reader for a UK gas engineer in 2026 is Tap to Pay on iPhone (zero hardware, take payment on the doorstep) or SumUp Solo with its free 4G SIM for connectivity in plant rooms and rural calls. Typical gas-engineer card payments run £80 to £3,000, spanning a quick service through to a full boiler installation, so no-contract pay-as-you-go pricing fits the lumpy, job-by-job cashflow far better than a fixed Dojo or Tyl contract. Gas Safe registration does not affect card acceptance, but a pay-by-link is worth adding for larger installs the customer wants to settle by card.
Our pick
Tap to Pay on iPhone
Acquirer: SumUp or Square
A mobile sole-trade with no fixed location and lumpy job values is best served by no-contract, no-hardware acceptance. Tap to Pay on iPhone removes the device cost; SumUp Solo with the free 4G SIM covers black-spots in plant rooms and rural properties. Pair with a pay-by-link for larger installs.
Why this trade matters
- Cashflow shape
- Job-by-job and lumpy. Winter heating-failure peak (October to February). Installs are large and occasional; services are small and frequent.
- Average transaction
- £80 to £3,000
- Contactless share
- ~40% (larger installs go chip and PIN or pay-by-link)
Watch outs
- Connectivity black-spots in plant rooms and rural calls; choose 4G-capable hardware.
- Large install payments can trigger SCA / 3DS; pay-by-link handles this cleanly.
- No-contract acquirers avoid tying a one-person trade to a fixed monthly fee.
Alternatives
- SumUp Solo (free 4G SIM)
- Zettle Reader 2
- Square Reader
