Exclusive Rates From as Low as 0.26%
An interchange fee is the charge that flows from your payment provider to your customer's card-issuing bank every time a card payment is processed, and it typically makes up 60-80% of the total cost of accepting card payments in the UK. Interchange rates are set by Visa and Mastercard, not by your acquirer or payment service provider, and they are regulated by law for UK consumer cards, currently capped at 0.2% for debit cards and 0.3% for credit cards. Understanding interchange is the single most useful thing a UK business owner can do before negotiating processing fees, because it reveals what is fixed by regulation and what your provider is actually marking up.
Key Takeaways
- Interchange fees are set by Visa and Mastercard and paid to the customer's card-issuing bank, not to your payment provider.
- UK-regulated consumer debit cards are capped at 0.2% and consumer credit cards at 0.3% under the EU Interchange Fee Regulation, retained in UK law post-Brexit.
- Commercial cards, corporate cards and non-UK/EEA issued cards are exempt from the cap and can cost 1.5-2.5% or more per transaction.
- Interchange typically accounts for 60-80% of total card processing costs, meaning most "provider margin" claims focus on the smaller remaining portion.
- Interchange++ pricing shows interchange as a separate, transparent line item, while blended pricing hides it inside a single flat percentage.
- UK businesses cannot negotiate interchange itself, but they can negotiate the markup their provider adds on top of it.
- Choosing the right pricing model and provider can save thousands of pounds a year even though interchange itself stays the same.
What Is an Interchange Fee?
An interchange fee is the charge paid to your customer's bank every time a card payment is made at your business. It is not set by your payment provider. It is set by Visa and Mastercard, and it flows from the "acquiring" side of the transaction (your bank or payment processor) to the "issuing" side (the bank that gave your customer their card). Interchange exists to compensate the issuing bank for the risk, fraud liability, and funding costs involved in extending credit or guaranteeing funds to the cardholder.
Every card transaction involves several parties: the cardholder, the merchant, the acquirer (your payment provider), the issuer (your customer's bank), and the card scheme (Visa or Mastercard) that sets the rules and routes the transaction. Interchange is the fee paid between the acquiring and issuing banks, and it is baked into the overall rate you are charged, whether you can see it broken out or not.
Why Interchange Exists
Card schemes designed interchange fees to balance incentives across the payment ecosystem. Issuing banks need a reason to issue cards, offer rewards, and absorb fraud losses, while merchants need a reliable, instant payment guarantee. Interchange is the mechanism that funds the issuing side of that arrangement, and it has existed in some form since card networks began in the 1960s and 1970s.
Who Sets Interchange Fees in the UK?
Interchange rates are set by the card schemes, Visa and Mastercard, not by individual banks or payment providers. However, in the UK and EU, interchange fees on consumer cards are capped by regulation. The Interchange Fee Regulation (IFR), originally an EU regulation, was retained in UK law following Brexit and continues to be enforced by the Payment Systems Regulator (PSR).
| Card Type | UK Regulated Cap | Applies To |
|---|---|---|
| Consumer Debit Card | 0.2% | UK-issued personal debit cards (Visa Debit, Mastercard Debit) |
| Consumer Credit Card | 0.3% | UK-issued personal credit cards |
| Commercial/Business Debit Card | Uncapped | Business debit cards issued to companies |
| Commercial/Business Credit Card | Uncapped | Corporate credit and charge cards |
| Non-UK/EEA Issued Cards | Uncapped | Cards issued outside the UK and EEA, including many US cards |
This distinction matters enormously. A business that takes a high proportion of payments from commercial cards or international visitors will see a materially higher blended interchange cost than a business whose customers pay almost exclusively with UK personal debit cards.
What UK Businesses Actually Pay
The regulated caps set a ceiling for consumer cards, but actual interchange rates vary by card type, transaction channel, and whether the card is present or not. Below is a realistic breakdown of typical UK interchange rates across common categories.
| Transaction Type | Typical UK Interchange Rate | Notes |
|---|---|---|
| UK Consumer Debit (chip & PIN/contactless) | Up to 0.2% | Lowest cost category, most common in UK retail |
| UK Consumer Credit | Up to 0.3% | Slightly higher than debit due to credit risk |
| UK Commercial Debit/Credit | 0.9% - 1.8% | Uncapped; common for B2B suppliers |
| EEA-issued Consumer Cards | 0.2% - 0.3% | Same caps apply within EEA reciprocal arrangements |
| Non-EEA Issued Cards (e.g. US, Asia) | 1.5% - 2.5%+ | Uncapped; significant for tourism and e-commerce businesses |
| Card-Not-Present (online) Transactions | Slightly higher than card-present | Reflects higher fraud risk in remote transactions |
For a typical UK retailer or hospitality business taking mostly UK consumer debit and credit cards, blended interchange cost often lands somewhere between 0.2% and 0.4% of turnover. Businesses with significant B2B, corporate card, or international customer volume can see blended interchange costs closer to 0.8% to 1.2%, even before scheme fees and provider markup are added.
How Interchange Fits Into Your Total Processing Cost
Interchange is only one of three components that make up the total rate you pay to accept card payments. Understanding all three is essential to spotting whether your provider's pricing is competitive.
The Three Layers of Card Processing Cost
- Interchange fee - paid to the card-issuing bank, set by Visa/Mastercard, capped for consumer cards.
- Scheme fee - paid to Visa or Mastercard directly for running the network, typically 0.01%-0.1% depending on transaction type. See our full breakdown in Authorisation, Scheme and Minimum Fees Explained for UK Merchants.
- Acquirer/provider markup - the margin your payment provider or merchant acquirer adds on top, which is the only genuinely negotiable part of the fee.
When you see a headline rate like "1.75% per transaction" from a provider, that figure is a blend of all three layers. If you are on a blended pricing plan, you often cannot see how much is interchange, how much is scheme fee, and how much is pure markup. This is precisely why interchange transparency matters so much for cost control.
Blended Pricing vs Interchange++ Pricing
How your provider structures your pricing determines whether you can actually see the interchange fee at all. This is one of the most consequential decisions a UK business makes when choosing a payment provider.
Blended Pricing
Under blended pricing, you pay a single flat percentage per transaction (for example, 1.5%) regardless of the card type used. Your provider absorbs the variation between low-cost UK debit cards and high-cost commercial or international cards, and prices in a margin to cover the average. This is simple to understand but usually more expensive over time, particularly for businesses whose customers mostly pay with low-cost UK debit cards, because you are effectively subsidising the provider's exposure to higher-cost card types.
Interchange++ Pricing
Under interchange++ (sometimes called "interchange plus" or "cost-plus") pricing, you are charged the exact interchange fee for each transaction, plus the exact scheme fee, plus a fixed, transparent markup agreed with your provider. This structure reveals precisely how much of your cost is genuinely fixed by Visa/Mastercard and how much is your provider's margin. For businesses processing more than roughly £15,000-£20,000 a month, interchange++ pricing is almost always cheaper and gives far greater negotiating leverage.
| Pricing Model | Transparency | Best Suited To | Typical Cost Impact |
|---|---|---|---|
| Blended Pricing | Low - interchange hidden inside one rate | Very small businesses, low transaction volumes | Often 0.2%-0.5% more expensive overall |
| Interchange++ Pricing | High - each fee itemised separately | Medium to large businesses, higher volumes | Lower cost, easier to audit and negotiate |
If you are unsure which model you are currently on, check your monthly statement. A statement listing "interchange," "scheme fee," and "markup" as separate lines confirms you are on interchange++. A single combined percentage per transaction confirms blended pricing. For a full breakdown of every term you might encounter, see our Card Processing Fees Glossary.
Why Interchange Rates Differ Between Businesses
Two UK businesses of similar size and turnover can have meaningfully different blended interchange costs, and the reasons are entirely predictable once you know what to look for.
Customer Card Mix
A café where 95% of customers tap a UK personal debit card will have a much lower blended interchange cost than a B2B wholesaler whose customers frequently pay with commercial or corporate cards, which sit outside the regulated cap.
Card Present vs Card Not Present
In-person transactions using chip and PIN or contactless typically attract slightly lower interchange than online, phone, or card-not-present transactions, because the fraud risk profile is different. E-commerce businesses should expect a modest premium on interchange compared with equivalent in-store transactions.
International Customers
Tourism-facing businesses, hotels, and online retailers selling internationally will see a higher blended interchange rate whenever a customer pays with a non-UK/EEA issued card, since those fall outside the regulated cap and can run at 1.5% to 2.5% or more.
Debit vs Credit Usage
Even within the regulated categories, credit cards cost slightly more in interchange than debit cards. Businesses that see a high proportion of credit card spend, such as luxury retailers or travel businesses, will naturally carry a higher blended interchange cost than a grocery store. We cover this distinction in detail in Debit vs Credit Card Fees UK: Why You Pay Different Rates.
Can UK Businesses Negotiate Interchange Fees?
No. Interchange fees are set centrally by Visa and Mastercard and, for consumer cards, capped by UK regulation. No payment provider, however large, can negotiate a lower interchange rate on your behalf, because it is not their fee to set. What is negotiable is the markup your provider adds on top of interchange and scheme fees, along with any fixed monthly fees, PCI compliance charges, terminal rental costs, and minimum monthly service charges.
This is why understanding interchange is so valuable: it lets you identify exactly which part of your quote is fixed and which part is your provider's margin, so you know precisely what to push back on. For a step-by-step approach with real scripts and benchmark figures, see our guide on How to Negotiate Lower Card Processing Fees: Scripts and Benchmarks.
Practical Steps to Reduce Your Total Card Processing Cost
- Request an itemised statement. Ask your current provider to show interchange, scheme fees, and markup as separate lines. If they cannot or will not, that is a signal you are on an opaque blended rate.
- Compare like-for-like. When getting quotes from new providers, ask specifically whether the quoted rate is interchange++ or blended, and request the exact markup percentage on top of interchange.
- Review your card mix. If a large share of your transactions come from commercial cards or international customers, factor this into any quote, since a "low headline rate" quoted for average UK debit cards may not reflect your real cost base.
- Check for hidden minimum fees. Some providers charge a minimum monthly service fee regardless of volume, which can distort your effective rate on quieter months.
- Review your contract term. Understand any early termination costs before switching providers, particularly if you are locked into a multi-year agreement. See Early Termination Fees: What UK Merchant Contracts Actually Cost to Exit for details.
- Benchmark against your sector. Typical costs vary significantly between retail, hospitality, e-commerce and B2B. Our guide to Card Processing Fees by Business Type UK gives sector-specific benchmarks.
Interchange Fee Regulation: A Brief History
Interchange fees were largely unregulated across Europe until the early 2010s, when regulators concluded that opaque, high interchange rates were being passed on to consumers through higher retail prices without merchants having any real ability to negotiate. The EU Interchange Fee Regulation came into force in 2015, capping consumer debit interchange at 0.2% and consumer credit interchange at 0.3% across the EU, including the UK at the time.
Following Brexit, the UK retained these caps in domestic law, and they continue to be enforced by the Payment Systems Regulator. However, a notable divergence occurred in 2021 and 2022, when Mastercard and Visa significantly increased interchange fees on UK consumers' card payments made to EU-based merchants, and vice versa, because reciprocal EEA arrangements no longer applied automatically post-Brexit. The PSR has since investigated these increases, and the long-term regulatory picture for cross-border UK-EU interchange remains an active area of scrutiny.
Frequently Asked Questions
What is the difference between an interchange fee and a scheme fee?
An interchange fee is paid to the customer's card-issuing bank to compensate for risk and funding costs, while a scheme fee is paid directly to Visa or Mastercard for operating the payment network itself. Both are separate from the markup your payment provider charges, and together the three make up your total processing cost.
Are interchange fees the same for every UK business?
No. Interchange rates are capped for UK consumer debit (0.2%) and credit (0.3%) cards, but commercial cards, corporate cards and cards issued outside the UK and EEA are uncapped and can cost significantly more, often 1% to 2.5%. Your actual blended interchange cost depends heavily on your customer mix.
Can my payment provider reduce my interchange fee?
No, interchange fees are set by Visa and Mastercard, not by individual acquirers or payment providers, so no provider can negotiate a lower interchange rate on your behalf. What you can negotiate is the markup your provider adds on top of interchange and scheme fees.
Why do online businesses often pay more in interchange than physical shops?
Card-not-present transactions, which cover online, phone and mail order payments, generally carry a slightly higher interchange rate than in-person chip and PIN or contactless payments because the fraud risk is considered higher when the card and cardholder cannot be physically verified.
Does interchange++ pricing always work out cheaper than blended pricing?
For most businesses processing meaningful volume, interchange++ pricing tends to be cheaper because it removes the buffer that providers build into blended rates to cover riskier or costlier card types. However, very small or low-volume businesses may find a straightforward blended rate easier to manage and occasionally comparable in cost.
How can I check whether I am currently paying a fair rate?
Request a detailed statement from your current provider showing interchange, scheme fees, and markup as separate line items, then compare your effective blended rate against typical UK benchmarks for your sector and card mix. Using a free, independent comparison service is the fastest way to establish whether your current markup is competitive.
Will interchange fees in the UK change again in future?
The regulated caps on UK consumer debit and credit interchange have remained stable since 2015, but cross-border UK-EU interchange rates increased sharply after Brexit and remain under active review by the Payment Systems Regulator. Businesses with significant EU customer bases should keep an eye on regulatory updates in this area.
