UK card payments, contract traps
Card machine contract traps in 2026: termination fees, lock-ins and the "free" catch
Most card machine "deals" hide their real cost in the contract, not the headline rate. The three traps are long minimum terms (often 18 to 48 months), early termination fees that bill every remaining month if you leave, and "free" machines whose cost is recovered through higher transaction fees or a separate hardware-rental agreement. Kartapay is an independent introducer, not tied to any one provider, so this guide names the trap and the way out.
In one sentence
A card machine contract becomes a trap through three clauses: the minimum term that locks you in, the early termination fee that bills the remaining months if you leave early, and the "free" hardware whose cost is recovered through a higher blended rate or a separate rental. Read the term, renewal and ETF clauses before you sign, and compare total cost per £1,000 of turnover, not the headline rate.
The three traps
| Trap | What it looks like | The catch | What to check before signing |
|---|---|---|---|
| Long minimum term | "Just sign here, standard terms" | 18 to 48 month lock-in; auto-renews unless you give notice | Term length plus the renewal clause, in writing |
| Early termination fee | "Small admin fee if you leave" | Can bill every remaining month of the term at once | The exact ETF formula, in pounds |
| "Free" card machine | "£0 hardware" | Recovered via a higher percentage plus pence, or a separate rental agreement | The blended cost per £1,000 turnover, not the rate |
None of these clauses is illegal. They are legal, common, and conflicted sellers rarely highlight them because they sell the contract or earn the lead. The Payment Systems Regulator's card-acquiring market review found contract and switching friction across the UK market, which is exactly what these clauses create.
When a fixed contract actually wins
- High, stable monthly volume where a negotiated rate beats pay-as-you-go.
- You want integrated EPOS or till hardware bundled and supported under one agreement.
When no-contract wins
- Seasonal, low or unpredictable volume (market stall, mobile trade, pop-up).
- A new business unsure of its volume. Avoid the lock-in until turnover is known.
Decision matrix by situation
- Mid-contract and unhappy → request the early termination fee in writing, diarise the term-end date, and switch at renewal so you avoid the fee.
- Offered a "free" machine → ask for the cost per £1,000 of turnover, not the headline rate, and compare it against a no-monthly-fee reader.
- Being pressured to sign today → that pressure is the signal. A neutral introducer never needs a same-day signature.
How to leave a contract without paying twice
- Get your current minimum term plus renewal date in writing.
- Calculate the early termination fee (remaining months × monthly cost) and weigh it against staying to the term end.
- Line up the replacement before you give notice. Serve notice in the form and within the window the contract requires.

Frequently asked
Are free card machines really free?
No. The hardware is free; the cost is recovered through transaction fees or a separate rental agreement. Compare the total cost per £1,000 of turnover rather than the advertised rate.
How long are card machine contracts?
Commonly 18 to 48 months with auto-renewal. Pay-as-you-go readers (SumUp, Square, Zettle) have no minimum term.
Can I be charged for leaving early?
Yes. An early termination fee can bill every remaining month of the minimum term. Always get the formula in writing first.
Is a card machine deal a scam if it locks me in?
Long terms and early termination fees are legal, not a scam, but conflicted sellers rarely highlight them. Read the term, renewal and ETF clauses before signing.
