Credit card processing fees UK — what you're actually paying in 2026

If you run a UK business and you take card payments, the rate quoted to you on day one is almost never the rate you actually pay. The headline number on a sales call is one component of seven, and the gap between what you think you pay and what you actually pay has cost UK businesses billions over the last decade. The Payment Systems Regulator estimates that since Brexit, just the cross-border interchange increase alone has cost UK businesses £150–200 million per year, with 95 per cent of the increase passed straight through to merchants.

This guide breaks down every component of a UK card processing fee in plain English, walks through a worked example for a £100,000-turnover business, and shows you how to read the three pricing models providers use so you can spot what you are actually being charged for.

What you are actually paying — the seven layers

A merchant service charge (MSC) is a stack of seven things, not one rate. Six of them are real fees that always apply, and the seventh is the surprise charge most providers do not advertise.

1. Interchange

The largest single line. Paid by the acquirer (your card processor) to the card-issuing bank. For UK domestic transactions, capped at 0.20 per cent for debit cards and 0.30 per cent for credit cards under the retained EU Interchange Fee Regulation. For cross-border UK-EEA transactions, fees had risen to 1.15 per cent on debit and 1.50 per cent on credit until the PSR's January 2026 cap brought them back down. Visa, Mastercard and Revolut challenged the PSR's authority at the High Court in January 2026 and lost.

2. Scheme fee

Paid by the acquirer to Visa or Mastercard. Typically around 0.05 per cent of the transaction value plus a fixed component per authorisation. It rarely appears as a separate line on a small business quote — it is bundled into the headline rate — but it is there.

3. Acquirer markup (the provider's slice)

This is the part your provider actually keeps. It is also the only part where competition does any real work. Typically 0.20–0.80 per cent depending on your monthly card volume, average transaction size, and how aggressively you negotiated. A new salon doing £8,000 of card sales a month will pay a wider markup than a busy pub doing £80,000.

4. Authorisation fee

A flat fee charged every time a card is presented to the network for approval — typically 1–3 pence per transaction. This one matters more than it looks: a coffee shop taking 400 contactless transactions a day at £4 average will pay more in authorisation fees over a year than a fine-dining restaurant doing 80 transactions at £85 average, even though the restaurant processes more revenue.

5. PCI compliance fee

Payment Card Industry Data Security Standard compliance is mandatory if you accept cards. Providers either include it in your contract or bill it separately (typically £5–10 a month). If they bill it separately, check whether they auto-charge a "non-compliance" surcharge if you miss the annual self-assessment questionnaire deadline. Many do.

6. Terminal rental

Monthly hardware cost. Wireless terminals like a Dojo Go or Dojo Wired typically rent for £15–30 a month. Some providers separate this into a base rental plus a connectivity fee for the 4G SIM card; check both numbers before you sign.

7. The "non-compliance" charge

The surprise fee. Triggered when a provider decides you missed a PCI deadline, sent too many chargebacks, or fell below a minimum monthly volume threshold buried in the contract. £30 a month is typical; some providers charge it indefinitely once it kicks in. This is the line you want to ask about explicitly before you sign anything.

A worked example — the £100k turnover salon

Let us walk through what a real UK independent business actually pays. Take a beauty salon doing £100,000 a year in card sales, average transaction size £45, 60 per cent contactless (in line with the UK Finance figure of over 60 per cent of card transactions being contactless in early 2026), with a standard Dojo Wired counter terminal.

That salon was probably quoted "0.6 per cent" by a salesperson. The 0.6 per cent was real — for the markup line only. The other six lines add another 0.55 per cent in real money.

The point is not that the salesperson lied. It is that "the rate" is shorthand for a stack of seven things, and the only number that matters to your bank account is the blended rate you actually pay at the bottom.

The three pricing models — and which one you are actually on

Every UK provider sells one of these. Knowing which one you are on tells you exactly what to negotiate.

Blended pricing

You pay one headline rate (say, 0.79 per cent) on every transaction. Simple to understand, easy to budget, but you are paying the same rate for a 50p contactless coffee as for a £450 split-bill dinner. Best for low-volume businesses with simple transaction patterns. This is what most cafés, salons, and small retailers end up on.

Interchange-plus

You pay interchange (the variable cost) plus a fixed markup. Transparent — you can see what is going to the bank and what is going to your provider. Better for higher-volume businesses where the markup matters more than the headline simplicity. Standard for mid-market hospitality and retail. If your provider offers it and your monthly card turnover is over £40,000, switch to it.

Interchange-plus-plus (IC++ or IC+++)

Interchange plus scheme fee plus acquirer markup, all separated. Maximum transparency, maximum negotiating room. Mostly seen in larger businesses (£250k+ monthly turnover) because the additional reporting complexity is not worth it below that.

Most UK independents end up on blended pricing because it is what gets offered. Nothing says it has to stay that way.

What the PSR cap actually means for you

The cap that came into force in January 2026 — and was confirmed by the High Court after Visa, Mastercard and Revolut lost their challenge — limits cross-border UK-EEA interchange to 0.20 per cent on debit and 0.30 per cent on credit. That returns these fees to the pre-Brexit position.

In practice, if most of your card sales are from UK customers paying with UK cards, you will not see a dramatic change. If you sell online to EEA customers, or you are a tourist-heavy business in a destination city like London, Edinburgh, or York, you should see the interchange line on your statement drop noticeably from your second statement of 2026 onwards.

Critically, the PSR cap is only on interchange. Your acquirer's markup, scheme fees, PCI charges, and terminal rental are not affected. If your provider does not pass through the interchange reduction, that is on them, not on the regulator.

How to read your next merchant statement

Six questions to ask of any statement you get from any UK provider.

1. What is my blended rate you actually pay? Add up every fee on the statement, divide by your total card turnover for the month. That number is what you actually pay. Anything more than 1.5 per cent on a sub-£20k month or 1.2 per cent on a £50k+ month is high.

2. Is interchange listed separately? If yes, you are on interchange-plus or IC++. If no, you are on blended.

3. Is there an "ancillary fees" or "other charges" line you cannot explain? That is almost always non-compliance or out-of-contract surcharges. Ask in writing what triggered it.

4. Is my PCI compliance status shown? It should be. If you are not compliant, you are either being surcharged already or about to be.

5. What does my contract say about volume tiers? Many providers automatically raise your rate if you fall below a minimum monthly card volume. Below-tier surcharges are the most common surprise fee small businesses see.

6. When is my contract renewal date? Most UK card processing contracts auto-renew. The window to renegotiate is typically 60–90 days before renewal.

What a fair UK rate looks like in 2026

For a typical UK independent doing £30k–£100k a month in card sales, on standard contactless and chip-and-PIN with no e-commerce, here is what reasonable looks like:

• Effective blended rate: 0.6 per cent–1.2 per cent including all per-transaction fees
• Authorisation fee: 1–2p per transaction (not 5p+)
• PCI compliance: £0–8 a month (some good providers include it)
• Terminal rental: £15–25 a month for a single wireless terminal
• Non-compliance and minimum-volume surcharges: zero, with no minimum monthly card volume clause buried in the contract

If your statement shows worse than this, you are paying a tax on inattention. Nothing in the underlying technology forces a UK small business onto 1.7 per cent in 2026. The rates have come down. Most providers just do not tell you.
