The question a customer asks at the counter is simple: refund to card, how long? UK shops can answer it better once they see that a card refund has two halves, the part the shop controls and the part the customer's bank controls.
The shop refunds today, and the bank shows it later.
That gap is built into the way a card refund travels between three firms, each with its own deadline under the card scheme rules. UK consumer law adds a separate deadline for the shop.
We read the Visa and Mastercard rulebooks, the refund sections of UK consumer law, and the published refund pages of one UK bank and one card acquirer. Those pages show the limits on a real statement.
The lesson for an owner and a bookkeeper is practical: a shop that knows each deadline can give a customer a real date, keep a dated receipt, and spot the rare refund that is genuinely stuck.
Refund to card: how long (UK) from till to statement?
A UK card refund passes through the shop's acquirer, the card scheme and the customer's card issuer, and the rules give each stage several days. The acquirer processes card payments for the shop.
The issuer is the bank behind the customer's card.
Mastercard's Transaction Processing Rules set the acquirer's clock. A refund must be submitted for clearing within five calendar days of the refund date, and clearing hands the transaction details on to the issuer.
Visa sets the issuer's clock for the UK. The UK sits in Visa's Europe Region, and the rules for that region say: “An Issuer must post a Credit Transaction Receipt to a Cardholder’s account within 5 calendar days from the Settlement date.”
Mastercard asks its issuers to move much faster: they must post the refund to the cardholder's account, or adjust the available balance, within one day of receiving the clearing message from the acquirer.
Published bank pages give a narrower range than the rules. Chase UK tells its customers: “Once a refund has been processed, it should take an average of 1-3 working days to reach your account.” The same page adds that some refunds take up to a week.
An acquirer's estimate for the whole trip runs longer. Square's UK help centre says Square typically takes two to seven working days to process a refund, and the customer's bank can take another two to seven to post it.
Square puts the total at up to fourteen working days.
Square also allows a long window for card refunds. Its sellers can refund a card payment within one year of the original transaction date, and after that the refund has to be made outside Square.
What happens to a card refund between the till and the bank?
A card refund now starts with a real-time question. Since 18 October 2024, Mastercard has required online authorisation for refunds by merchants in its Europe Region, so the customer's bank is asked while the customer is still at the counter.
Authorisation means the issuer approves the transaction as it happens. Mastercard's rule is specific about timing: “The Acquirer must forward each refund Transaction authorization request to the Issuer at the time of the Transaction, rather than in a batch”.
The online step protects the shop at the till. Mastercard wants the merchant to receive the issuer's answer before it hands the customer a refund receipt.
Visa asks issuers to be ready for this message. An issuer must be able to receive an authorisation request for a refund, and it must approve at least 99% of these credits.
Clearing comes next, and it is the step that passes the refund details from the acquirer, through the card scheme, to the issuer that holds the customer's account.
Settlement follows clearing in both of the card schemes. Visa's glossary describes it as the reporting and transfer of the amounts that members owe each other as a result of clearing, and the five-day posting deadline runs from that date.
Here is a hypothetical example built only on those limits. A Mastercard refund keyed on a Friday could be cleared as late as the Wednesday, and no rule is broken by that timing.
Why does the customer see a pending refund before the money?
A pending line is the refund authorisation showing early. Visa tells issuers to “Process the Credit Transaction so that Cardholder-facing applications are updated with the pending credit information in the same timeframe as a purchase Transaction”.
Mastercard sets a similar standard for how the line looks. Its rule states: “The pending refund information must be displayed in a manner similar to that used for a pending purchase Transaction.”
Until it clears, a pending refund is not money to spend.
Mastercard advises issuers to treat it as a pending credit until the clearing record arrives and matches the authorisation, and to hold back the funds until then.
Holding the money for longer is allowed in some cases. Mastercard lets an issuer place a temporary hold on refund funds, within the law, if the circumstances or account history warrant the delay.
Those two stages explain what a customer sees on a banking app. A pending refund with no change in the available balance is most likely a refund that sits between authorisation and clearing.
Square describes the same stage from the shop's side. A customer should see a pending transaction within one to three working days of the refund being started, it says, and the final posting depends on the card-issuing bank.
What does UK law require of the shop?
When the Consumer Rights Act 2015 gives a customer a right to a refund, it also gives the shop a fixed deadline that does not depend on the banks. Section 20 states: “A refund under this section must be given without undue delay, and in any event within 14 days beginning with the day on which the trader agrees that the consumer is entitled to a refund.”
The same section also sets the refund method. The trader “must give the refund using the same means of payment as the consumer used, unless the consumer expressly agrees otherwise”, and must not charge the consumer a fee for it.
These refund rules protect consumers, not business buyers.
In the Act, a consumer “means an individual acting for purposes that are wholly or mainly outside that individual's trade, business, craft or profession”. A company buying from the shop falls outside them.
Online, phone and mail sales have their own clock. Under the Consumer Contracts Regulations, the refund is due within 14 days after the trader receives the goods back, or after the customer supplies evidence of sending them, if that comes first.
The government's guidance for businesses puts the online rule plainly: “You must refund the customer within 14 days of receiving the item back.” A shop cannot deduct fees unless the item has been used or damaged.
Delivery charges come back to the customer too, within limits. A shop must refund the cost of standard delivery, but if the customer paid for a dearer option, only the standard amount is due.
Even a sign in the window cannot narrow those rights. The same guidance says it is illegal to restrict customers' rights or mislead them, for example with a sign saying the shop does not accept returns or give refunds.
Goods bought in person in the shop follow different rules. The same guidance says a shop does not have to refund a customer who simply no longer wants an item, unless it was bought without being seen.
Sale prices change nothing about these refund rights. The guidance says customers have exactly the same rights to refunds when they buy in a sale as at full price.
A shop can ask for proof of purchase before it agrees to a refund, and the guidance lists a receipt, a bank statement or the packaging as acceptable evidence. It also says a shop only has to accept returns from the person who bought the item.
Section 20 says nothing about how bank processing counts toward the 14 days, so a dated refund receipt is the shop's best record of when it actually acted.
What is the card refund processing time on the shop's own account?
The shop's side starts when the refund is keyed. Square, as one example, takes the refund from the seller's Square balance first, and if that balance cannot cover it, the seller's linked bank account is charged for the amount.
The card fee usually stays with the provider. Square's help page is direct: “When you refund a payment, the processing fees for the payment aren’t refunded back to you.”
Visa's rules then decide which card gets the money, saying that “To the extent possible, the Merchant must process a Credit Transaction” to the same card that paid for the original purchase.
Cash or store credit is allowed only in listed cases. Visa names a customer with no receipt, a gift returned by someone other than the cardholder, and a refund to the card that is declined, among others.
Those listed cases matter most for returned gifts. When the customer returning a present is not the cardholder who paid, Visa lets the shop refund in cash, in-store credit or on a prepaid card instead.
Mastercard's rules let a refund be reversed only to correct a clerical error, such as a duplicate or wrong data, and only within one calendar day of the refund itself.
A mistaken double refund is therefore hard to undo.
No PIN or signature is needed for a Mastercard refund, though if a PIN is used at a chip terminal, the merchant must still obtain a successful PIN check.
One refund and one receipt is the safest till habit. The amount should be checked before the card is presented, and Mastercard's rules say a transaction receipt must be offered for a refund just as for a purchase.
What can a shop do when a refund never seems to arrive?
The first step is to confirm the refund left the shop. The receipt and the provider's transaction record show it, and Chase UK asks its own customers to contact the merchant first, then call the bank if more than a week has passed.
UK Finance gives cardholders the same advice in its FAQ. It says “it might be helpful for you to first approach your supplier before making a chargeback or Section 75 claim through your card issuer”.
The customer's bank must wait before it can act. For a promised refund that never posts, Visa's rules say: “Before initiating a Dispute, an Issuer must wait 15 calendar days”, counted from the date on the refund receipt.
The window for raising that dispute is long. Visa allows it up to 120 calendar days after the receipt date, and UK Finance describes a typical limit of 120 days from purchase, or from expected delivery, for chargebacks in general.
A dated receipt helps the shop here too. It shows the issuer when the credit was created, and it gives the customer a date to quote.
Three facts make a short counter script that saves calls later: the refund date, the card it went to, and the posting range the customer's own bank publishes.
What do the rules and the bank pages leave out?
The scheme rules set maximum times, not averages, and the rulebooks we read give no figure for a typical UK refund. We found no UK-wide statistic either.
The bank and acquirer figures are single examples, since Chase UK and Square describe only their own processes, and another issuer or provider can be faster or slower within the scheme limits.
Visa's public rules also leave gaps for this region, because for some processing matters they point Europe Region members to a separate Visa Europe processing document that we did not read.
Card schemes other than Visa and Mastercard sit outside this lesson. Their refund rules may differ, and Square notes that its pending-transaction notices cover only some networks.
Closed card accounts are another blind spot here. Square says a refund to an account closed within the last two months may still post. If it was closed for longer, the credit will fail.
In that case the seller must refund another way, such as cash or a gift card.
A short note on your own case: the provider's merchant agreement and support team, or an accountant for the bookkeeping side, can confirm how refunds post on your account.
What comes next for card refunds?
Faster refunds are already written into the card rulebooks. From 18 April 2026, Visa's rules describe a Faster Refund that is sent as an Original Credit Transaction, the push message Visa also uses for payouts.
Visa's Fast Funds service can make qualifying incoming credits of that type available within 30 minutes at participating issuers. Whether a given shop can use it depends on its acquirer and on a Visa guide outside the public rulebook.
Our view at the school is that the refund wait is mostly a communication problem, not a money problem.
A shop that hands over a dated receipt and names the bank's own posting range will hear fewer complaints than one that only says the money is on its way.
Task for this lesson: take the last three card refunds from the provider's dashboard and note the date each was keyed, the date the customer saw it if known, and the card type. Then compare those dates with the five-day deadlines in the scheme rules.
