Your first merchant statement lands, you find the fees column, and the obvious fix jumps straight out: add the card fee onto the bill. The straight answer on card payment surcharge UK rules is no. For consumer debit and credit cards it’s been banned since January 2018. There are legal alternatives though, and shrinking the fee itself is one of them.

The short answer: you can’t add a card fee to a consumer’s bill

No. If the person in front of you is a member of the public paying with a personal debit or credit card, you can’t charge them extra for using it. Not 50p. Not 1.5%. Nor a 30p charge on card payments under a tenner. It’s been off the table across the UK since 13 January 2018.

The rule lives in the Consumer Rights (Payment Surcharges) Regulations 2012, tightened in 2018. Before then you could add a fee, as long as it didn’t come to more than the payment genuinely cost you. That door is shut. For consumer cards you can’t add one at all.

It catches more than the obvious wording. A “card handling fee” is a surcharge. So is a “processing charge”, a “convenience fee”, or a booking fee that only appears once the customer picks card at the checkout. Giving it a friendlier name changes nothing. What counts is whether the customer ends up paying more because of how they chose to pay.

And no, a sign doesn’t fix it. Owners assume that being upfront makes the fee fair, so a laminated notice by the till must solve it. It doesn’t. Being open about something you’re not allowed to do only makes it easier to prove.

What the surcharging ban actually covers

The ban applies to you as the seller, not to your provider. Size doesn’t matter. Café with one countertop terminal, plumber taking payment on a phone, shop with a full till system: the rule is the same. If you’re selling to a consumer in the UK and they pay by personal debit or credit card, you can’t charge extra for the card.

It covers in-person sales, phone payments and online checkouts equally. A payment link you text to a customer is caught the same way a chip-and-pin sale at the counter is. The ban also reaches several electronic payment services beyond plain card payments, so a workaround built on a different rail usually isn’t the escape hatch it looks like.

A small number of payment types do sit outside it. Commercial cards are the main one. Where a charge is still permitted, it’s capped at what that payment genuinely costs your business, and you should make it clear before the customer commits. You can’t round it up to a neat 2% because the maths is easier that way.

The regulation itself is short and readable, and it’s the thing to check before you print anything: Regulation 6A of the Consumer Rights (Payment Surcharges) Regulations 2012. What follows here is how the rules land in a small shop, not legal advice. Planning anything unusual? Get someone qualified to look first.

The commercial card exception, and why it rarely helps a small shop

Here’s the carve-out everyone hears about. The ban is written around the card rather than the buyer, so commercial and corporate cards (the ones issued to a business rather than an individual) sit outside it. A sale to another business paid on an ordinary debit or credit card is still caught. In theory you can pass the cost on for a commercial card, capped at what that payment costs you.

In practice, it rarely earns its keep in a café or a salon. Three reasons.

First, you have to know it’s a commercial card before you take the payment, not after it settles. Check whether your terminal or till can flag the card type at the point of sale, because a customer standing at the counter with a queue behind them isn’t going to enjoy the delay while you work it out.

Second, the volume may not be there. If a handful of your sales a month are on company cards, you’re building a process for pennies.

Third, any charge you do apply still has to be capped at your actual cost for that transaction, and you should make it clear before the customer commits. Your merchant agreement may restrict it anyway. If most of your takings come from business customers on commercial cards, it’s worth a proper look. If you’re a takeaway on a Friday night, forget it.

Minimum spend: the route most small shops take

A minimum spend isn’t a surcharge. You’re not adding anything to the price. You’re setting a condition on when you’ll accept a card at all. The surcharge regulations don’t ban that, which is why some shops still ask for a minimum on card.

Two things to check before you print the sign. Your merchant agreement comes first: it may restrict a minimum card spend, so read yours or ask your provider directly. Second, the number should be visible before the customer orders, not sprung on them at the card machine. Put it at the door, at the counter and on the menu, and keep it the same number in all three places.

Set it against your real cost floor rather than a round number that feels right. On a £2 sale, a per-transaction fee of a few pence plus your percentage is a meaningful slice of a thin margin. On a £15 sale it’s noise. Work out where your break-even actually sits and set the threshold just above it.

Be honest about the cost too. Some customers may walk. Others may add something they didn’t want to reach the minimum. A minimum is a blunt tool, and it works best where your average spend already sits near the threshold.

Build the cost into your prices instead

This is the boring answer, and it’s the one that holds up. Card acceptance is a cost of trading, the same as your rent, your bin collection or your till roll. You don’t itemise those on the bill. You price so they’re covered.

Nothing stops you raising your prices. The regulations govern charging extra for a payment method, not what you charge for the thing you’re selling. A headline price that quietly absorbs your card cost is completely legitimate, and the customer sees one number they can actually pay.

One caution. Don’t advertise one price and charge another. If your menu says £3.00, the customer pays £3.00 whichever way they tap. Build the cost in before the price goes on the board, not after the order goes in.

The cash discount grey area

Offering a discount for paying a particular way is a grey area. It’s the opening people reach for when they hear surcharging is out.

The trouble is what usually gets built. Two prices go on the board, the card price is the price you were always going to charge, and the “cash discount” is a surcharge wearing a better jacket. If your card price is above your normal price, you’ve built a surcharge.

If you want to reward cash, do it properly. Set one genuine list price you’d honour for any customer, then discount from it, and keep the discount in proportion to what handling cash actually saves you. Dual pricing also causes friction at the till, and it invites the one conversation nobody in hospitality wants during a lunch rush. It’s one of the few areas here where the line depends on your exact setup, so get advice before you commit.

What happens if you charge it anyway

Two things, and the first one is refunds. A surcharge the regulations ban isn’t something you should hold on to, so expect to refund it, and that applies to every customer you charged, not only the one who complained.

The second is enforcement. Trading Standards handle these regulations and can take civil enforcement action against a business that keeps charging. A single complaint is enough for an enforcement authority to look at what you’ve been charging.

There’s a commercial cost on top. A “card fee” line on a receipt can end up in a one-star review. Your merchant agreement may prohibit surcharging outright too, separately from the law.

The honest summary: the upside is a percentage point or two, and the downside is refunds, an enforcement letter and a review you can’t delete. Not a good trade.

If you can’t pass the fee on, cut the fee

This is the part worth your afternoon. You can’t move the cost onto the customer, so the only lever left is the cost itself.

Run the numbers on your own takings. On £8,000 a month of card sales, a rate of 1.6% costs you £128. At 1.3% it’s £104. That 0.3% is £24 a month, £288 a year, if a switch gets you that rate.

The percentage is only half the story, mind. Authorisation fees, a minimum monthly service charge, PCI fees, terminal rental and a higher rate on commercial or rewards cards all sit underneath the headline number, and they’re where a cheap-looking deal often stops being cheap. We’ve broken those down in the hidden costs of card machines in the UK, and there’s a full price breakdown in how much a card machine actually costs.

Check your contract before you do anything else. If you signed a long term, you may not be able to switch yet. Rolling monthly deals with no long contract do exist. We’ve listed who still offers them in card machines with no long contract. If you’re out of contract or close to it, switching without downtime is worth a look.

FAQs

Can I apply a card payment surcharge in the UK if I display it clearly?

No. For consumer debit and credit cards the charge is banned outright, so displaying it doesn’t make it lawful. The 2018 ban replaced the old cost-based cap.

Can I charge a fee to a business paying on a company card?

Commercial and corporate cards sit outside the ban, so a charge is generally possible there. It still has to be capped at what that payment actually costs you, you should make it clear before the customer commits, and your merchant agreement may restrict it anyway.

Is a £5 minimum spend on card legal?

A minimum spend isn’t a surcharge, so the surcharge regulations don’t ban it. Check your merchant agreement and card scheme rules first, and make sure the sign is visible before the customer orders rather than at the card machine.

What about a service charge on a restaurant bill?

A service charge applied to every customer regardless of how they pay isn’t a payment surcharge, so it’s a different question entirely. It becomes a surcharge the moment it only lands on people paying by card.
