FAQs
What is the best card machine for a UK plumber, electrician or builder?
Tap to Pay on iPhone wins overall: zero hardware, no contract, supports Apple Pay, Google Pay and contactless card. SumUp Solo at £99 wins as a dedicated reader for tradesmen who do not want to use their personal phone. For builders running website-quote sign-offs, Stripe Checkout for the online deposit plus Tap to Pay for the balance.
How do UK tradesmen handle staged payments (deposit + balance)?
Card-on-file via Stripe Billing or Adyen Subscriptions: customer SCA-authenticates at job sign-off, deposit charges immediately, balance charges automatically on a set date or after completion confirmation. MerchantHQ wires this up. Avoid asking for full payment upfront unless you are running the trade on a deposit-only basis (uncommon).
What about emergency callout charges for plumbers and electricians?
Emergency callouts can be charged on the spot via Tap to Pay or hardware reader. Many tradesmen charge a standard callout fee (£60 to £150) plus parts and labour. Card acceptance at the door reduces unpaid-callout risk on customer-defaulting cases.
Can a UK tradesman charge a card fee on top of the bill?
No. UK card surcharging on consumer transactions has been illegal since January 2018. The card-acceptance cost has to be built into your quoted rate, not added at point-of-sale. Surcharging risks a Trading Standards complaint.
