Yes - a UK business can legally refuse cash. 'Legal tender' is one of the most misunderstood phrases in British life, and it does not force any shop to accept notes and coins. But whether you legally can go cashless and whether you commercially should are two different questions. Here are both answers.
The law: you can refuse cash
There is no UK law requiring a business to accept cash. A shop sale is a contract, and you're free to set the terms - including 'card only'. Refusing cash before a sale happens is entirely legal, the same way a vending machine legally refuses £50 notes.
'Legal tender' has a narrow technical meaning: it's about settling a court-recognised debt - if you owe money and offer legal tender, you can't then be sued for non-payment. Buying a coffee isn't a debt; you're negotiating a sale, and the seller sets the terms. That's why 'but it's legal tender!' has no force at the till.
Why businesses go card-only
The case for cashless is mostly about time and risk, and it's stronger than most owners expect once they cost it honestly:
- Cashing up, floats, change runs and banking visits: typically 3-5 hours a week for a busy counter. That's paid time.
- Banks increasingly charge small businesses to deposit cash - often 0.5%-1% of the amount. Cash has a processing fee too; it's just hidden.
- Theft and shrinkage risk drops to near zero - no till skimming, no closing-time walk to the bank.
- Every sale lands in reports automatically, which makes VAT, reconciliation and staffing decisions cleaner.
Why you might keep taking cash anyway
Cash still matters to real customers: older people, kids, anyone budgeting hard, and anyone whose bank is having a bad day. Roughly one in five UK payments is still cash, and it skews towards exactly the local, habitual customers a small business lives on. A pub or cafe that goes card-only is quietly telling some regulars they're not welcome.
There's also resilience: when the internet fails or a provider has an outage, cash is the payment method that still works. Plenty of card-only businesses discovered this the hard way during past outages. If you do go cashless, have an offline plan - even if it's just a notebook and trust.
If you go card-only, do it properly
Signage before the order, not at the till - 'Card payments only' at the door and on the menu removes the awkward moment entirely. Make sure your setup can actually carry the load: a reader with a backup, Tap to Pay on a phone as the emergency fallback, and payouts fast enough that going cashless doesn't create a cash-flow gap - see which providers pay out same-day.
And if the maths is the deciding factor, run it: cashless means every sale carries a card fee, so a business moving £3,000 of monthly cash sales onto cards adds roughly £50/month in fees at typical rates - against the hours and deposit charges saved. The fee calculator gives you your number in two minutes.
FAQs
Is it discrimination to refuse cash?
It's not unlawful discrimination in the legal sense - payment method isn't a protected characteristic. But it does exclude some customers in practice, which is a commercial decision worth making deliberately rather than by default.
Can a pub or restaurant refuse cash after I've eaten?
This is the interesting edge case - once you've consumed the meal, a debt arguably exists, and refusing legal tender for a debt gets murky. In practice businesses displaying 'card only' clearly before you order avoid the problem entirely.
Do market traders have to take cash?
No - same rules. Though in practice most market traders find refusing cash costs real sales; a £19 card reader alongside the cash tin covers both crowds.
Can I refuse £50 notes but take other cash?
Yes. You can set any payment terms you like before the sale - card only, no £50s, exact change after 9pm. Clarity beats confrontation: put it on a sign.
