How Do Chargebacks Work in the UK? A Merchant's Guide

A chargeback takes your money first and asks for your side of the story second. By the time the email arrives, the clock is already running.

This is how chargebacks work in the UK: a cardholder disputes a payment with their bank, the bank (the issuer) pulls the money back through your payment provider (the acquirer), and you get a short window to send evidence. The card company reviews both sides and its decision is final.

Last updated: 6 October 2026. Written by the ChargeFix team.

The 30-second answer (TL;DR)

The UK chargeback process involves five parties: the cardholder, their bank (the issuer), your payment provider (the acquirer), the card scheme and you. Only the issuer and the card company decide who wins.

The money leaves first. On Shopify Payments in the UK, the disputed amount and a £10 fee are taken when the chargeback opens, and both come back only if you win.

You usually get 7 to 21 days to respond. The card company can then take up to 75 days to rule.

An inquiry is the gentler version. Nothing is taken while it runs, but it can turn into a full chargeback.

A UK chargeback is not a refund and not a Section 75 claim. It is a card scheme process, and customers generally have 120 days to start one.

Winning does not wipe the dispute from your chargeback rate, so prevention is worth more than any single win.

Evidence decides cases. Lead with direct proof, label every item and file before the due date.

From dispute to decision at a glance

Stage	Who acts	What happens to your money	Your move
1. Customer disputes the payment	Cardholder and issuer	Nothing yet, or an inquiry with no debit	Check the order and watch for the notice
2. Chargeback is raised	Issuer, through the scheme and acquirer	Amount plus fee taken straight away	Open the dispute and note the due date
3. You respond	You	Still out of pocket	Submit labelled evidence on the response form
4. Review	Issuer and card company	Waiting	Leave it alone and keep records
5. Decision	Card company	Returned if you win, gone if you lose	Log the outcome and fix the cause

What is a chargeback, and how is it different from a refund?

A UK chargeback is a reversal of a card payment that the cardholder's bank starts, not you. The bank takes the money back under card scheme rules and leaves you to prove the sale was legitimate. A refund is the opposite: you choose to send the money back yourself.

The word sounds technical, but the idea is plain. Someone paid your store by card. Later they told their bank something was wrong with that payment, and the bank agreed to reverse it while the question gets looked at.

In the UK this is usually called the chargeback scheme. MoneyHelper describes it as an arrangement that Visa, Mastercard and American Express have signed up to, and not a law passed by Parliament. That explains why it feels so rigid. The rules are scheme rules, written for banks, and they apply the same way whether you sell candles from a spare room or ship from a warehouse.

Keep that in mind through the rest of this guide, because how chargebacks work in the UK depends on it: the customer's bank is in charge of the dispute, and you are the one answering it.

New merchants often mix the two up. If a customer emails you asking for their money back and you send it, that is a refund. If the customer skips you and goes to their bank, that is a dispute, and it follows a different path at a different cost. Getting the chargeback vs refund distinction clear early saves a lot of confusion later.

Chargeback vs refund: the practical differences

	Refund	Chargeback
Who starts it	You	The cardholder's bank, after the customer asks
Who decides	You	The issuer and the card company
When the money moves	When you issue it	As soon as the chargeback opens
Dispute fee	None	Applied when it opens, returned if you win
Can you contest it	Not relevant	Yes, with evidence before the due date
Effect on your chargeback rate	No dispute is filed, so nothing is counted	Counted, even if you win

The chargeback vs refund gap is widest on cost, because only one of them comes with a fee and a mark on your rate.

How a refund interacts with a dispute that is already open isn't covered in the sources reviewed for this guide, so check with Shopify Support before refunding an order that has an open chargeback.

Who are the five parties in the UK chargeback process?

Five parties take part in a UK chargeback: the cardholder, the issuer (the cardholder's bank), the acquirer (the bank or provider that processes your card payments), the card scheme such as Visa or Mastercard, and you. The scheme writes the rules, the issuer applies them on the customer's behalf, and the acquirer passes the claim on to you.

Party	Role	What it means for you
Cardholder	The person whose card was charged	Often your customer, but not always
Issuer	The bank or provider that issued the card	Raises the chargeback and reviews your evidence
Acquirer	The bank or provider processing your card payments	Passes the dispute on and collects the money back
Card scheme	Visa, Mastercard and others	Sets the rules, timelines and reason categories
You	The merchant	Prove the sale was genuine, or accept the loss

Seen from your side, the chain runs customer, issuer, scheme, acquirer, you. Each link passes the claim along, and none of them argues your case for you.

What is an issuer?

The issuer is the bank, building society or card company that gave the customer their card. It is the customer's side of the table. When someone says "I'm calling my bank about this charge", they mean the issuer.

What is an acquirer?

The acquirer is the other end of the payment. It is the bank or payment company that lets you accept cards and settles the money to you. Chargeback money flows back through it, and the issuer and acquirer settle between themselves, which is why disputes reach you as a deduction and not as a request. Think of the issuer and acquirer as the two banks that sit either side of the card scheme, with the money moving from one to the other.

Where does Shopify fit in?

Shopify's own help pages are clear on this point: Shopify isn't liable for a UK chargeback and isn't involved in deciding how it ends. If you take payments through Shopify Payments, you see the dispute in your admin and respond there, but the verdict belongs to the customer's bank and the card company.

The cardholder is also not always your customer. Shopify's chargebacks overview notes that the person disputing can be someone who believes their card was used on your store without permission. That matters later, when we look at what evidence helps.

How do chargebacks work step by step?

Every chargeback follows six steps: the customer disputes the payment, the issuer decides whether to raise a chargeback, the money leaves your account, you send evidence, the card company reviews it, and a final decision is made. The first three happen fast. The last three take weeks.

That is how chargebacks work in the UK in outline. The detail below shows where you can change the outcome, and where you can't.

Step 1: the customer contacts their bank

A UK chargeback often begins with a phone call or an app tap that you never see.

In the UK chargeback process, customers are expected to try you first. MoneyHelper tells shoppers to speak to the company before asking their bank to investigate, and Shopify says card networks expect the same. Plenty skip that step anyway, because calling the bank feels faster than waiting for an email reply.

When the customer does call the bank, the reason they give shapes everything that follows. Shopify groups disputes into seven categories, and the evidence that helps is different for each one.

Category	What the customer is saying	Evidence that usually helps most
Credit not processed	I was promised a refund and it never came	The refund record and the date it was sent
Duplicate charge	I was charged twice for one purchase	Transaction logs showing separate orders or one charge
Fraudulent transaction	I didn't make this payment	Address and security code matches, order history, delivery to a known address
Product not received	It never arrived	Carrier tracking and proof of delivery
Product unacceptable	It's faulty or not as described	Listing at purchase, dispatch records, messages
Subscription canceled	I cancelled and was still charged	Terms, cancellation records, usage after the charge
General	The amount is wrong or something else	Itemised receipt and checkout confirmation

Our Shopify chargebacks UK guide links to a full walkthrough for each category.

Step 2: the issuer chooses between a chargeback and an inquiry

The issuer reviews what the customer told it. If the claim fits the chargeback scheme rules, the bank can start either a chargeback or an inquiry. Every UK chargeback you receive passes through this fork. Shopify's help centre sets out the difference clearly.

	Chargeback	Inquiry
Your money	Disputed amount and fee withdrawn immediately	Nothing taken while it runs
If you win	Amount and fee returned	Closed, no action needed
If the customer wins	You lose both	It may escalate to a full chargeback

We cover the practical difference in more detail in Shopify chargeback vs inquiry.

Step 3: the money leaves your account

This is the part of a UK chargeback that surprises people. The debit happens before you have said a word, because the issuer and acquirer settle the money between themselves first. Shopify's guidance says the disputed amount and fee are withdrawn when a chargeback is opened, and that you are alerted with a deadline to respond.

If your Shopify Payments balance can't cover it, UK stores are debited from the bank account on file, outside the normal payout schedule. Shopify says a second attempt follows after three business days if the first one fails.

Step 4: you respond with evidence

This reply is called representment. It is your formal answer to the chargeback: a package of evidence that the issuer and acquirer pass along the same chain the claim came down, arguing that the sale was legitimate. What is representment in practice? It is the only point in the process where you get to speak, so it deserves most of your time.

On Shopify, you build the response on the order's chargeback form. Shopify structures good evidence in a particular order, and it is worth copying:

Direct proof, such as signed delivery, tracking showing delivered to the right address, a refund record or usage logs.
Customer acknowledgement, such as messages where they thank you, ask about the product or confirm receipt.
Policy documents they agreed to at checkout.
Supporting context, such as order history and address checks.

Our step-by-step guide to how to respond to a Shopify chargeback adds copy-paste templates for each stage.

Step 5: the card company reviews and decides

This is the part of how chargebacks work that merchants like least: the verdict is made without you in the room.

Once you submit, the issuer and card company review both sides. You don't get to join a call or argue your case live. The decision rests on what is on the page.

There are three possible outcomes: you win, you win in part, or the customer wins. Shopify says there is no appeal once the bank or card company has ruled, and Shopify can't overturn the result.

Step 6: what happens next

If you win, the disputed amount and the fee come back. The usual timing for the money and fee to return is something to check against your own payout line items. Shopify's help page also warns that a customer's bank can dispute the same transaction again after a win, so keep your evidence file.

If you lose a UK chargeback, the money stays gone. The useful part is what you do next: log the reason, find the cause and fix it, because a repeat cause is where chargebacks turn into a pattern.

How do chargebacks work on Shopify in the UK?

On Shopify Payments, a UK chargeback appears in your admin with a due date. Shopify pre-fills much of the evidence from your order records, you add what only you have, and Shopify submits the response to the card company. You see the status move from open to submitted to won or lost.

Shopify says the following is included automatically when it is available for the order:

Product details, with title, variant and quantity.
Customer name and email.
Billing and shipping addresses saved on the order.
The IP address used to place the order.
Shipping date, carrier and tracking number for each fulfilment.
A tracking PDF, which for some carriers can include the carrier's delivery photo.
Refund records for the order.
Previous undisputed orders from the same customer, and any earlier disputes they opened.

That is a solid start for a UK chargeback on Shopify Payments. It comes only from your Shopify admin, though. It won't include your emails with the customer, a signature the carrier holds, usage logs for digital goods or the listing as it looked on the day of purchase. Our guide to what Shopify submits for you breaks down what is and isn't filed automatically.

That is how chargebacks work on Shopify in the UK from your side of the screen. One more feature to know about is network dispute resolution. Shopify says that if your store is enrolled in such a programme, some disputes are resolved automatically before they become formal chargebacks, and there is no evidence window for them. Visa Rapid Dispute Resolution is the example Shopify gives. Those disputes still count towards the rate Shopify uses to monitor your account.

Shopify also notes that some Shop Pay orders are covered by Shopify Protect, which reimburses eligible fraud-related chargebacks. Check the order details to see whether a given order is covered. This guide doesn't assume that UK orders are.

Menu wording changes, so follow what your admin shows when you look for the dispute on the order.

How long does a UK chargeback take?

On Shopify, you usually have 7 to 21 days to respond. After you submit, the card company can take up to 75 days to decide. Add the time before the dispute reaches you, and a single UK chargeback can sit open for the better part of three months.

A UK chargeback rarely feels quick, because the response window and the review period run one after the other. Inquiries run on a slightly different clock. Shopify says the review of an inquiry usually takes 65 to 75 days and may take longer.

Stage	Example date	What is going on
Order delivered	Friday 2 October 2026	Carrier marks it delivered
Customer contacts bank	Monday 5 October 2026	Issuer starts looking at the claim
Chargeback opens in Shopify	Monday 12 October 2026	Money and fee leave, due date set
Due date	Monday 26 October 2026	A 14 day window in this illustration
You submit	Friday 23 October 2026	Three days before the due date
Latest decision	Wednesday 6 January 2027	75 days after submission

That table is an illustration, not a prediction. Your due date appears in your admin, and ours is only an example. How long a Shopify chargeback takes walks through how due dates are counted and the cash flow side.

The customer has a clock too. MoneyHelper tells UK cardholders they should be told the outcome of a claim within eight weeks. That is the consumer's side. The merchant's side on Shopify can run longer, so don't use the customer's timetable to plan your cash.

How much does a UK chargeback really cost a merchant?

The headline cost of a UK chargeback is the sale value plus the dispute fee. The real cost is the sale value, the fee, the goods and postage you already paid for, and the time you spend. On a small order, losing one dispute can wipe out the profit from several good ones.

Here is a worked illustration of a UK chargeback, with invented numbers, on a single order.

Line	No dispute	Dispute lost	Dispute won
Customer pays (including £4.00 postage)	£84.00	£0.00	£84.00
Stock cost	£31.00	£31.00	£31.00
Postage label	£3.20	£3.20	£3.20
Dispute fee	£0.00	£10.00	£0.00
Net result	£49.80	-£44.20	£49.80

The sums: £84.00 less £34.20 of costs gives £49.80 profit. When the dispute is lost, you keep none of the £84.00, still carry the £34.20 of costs and pay the £10.00 fee, which is a loss of £44.20. The swing between a clean sale and a lost dispute is £94.00, which is the £84.00 sale plus the £10.00 fee.

This example leaves out payment processing fees, because how those are treated on a disputed payment isn't covered in the sources reviewed. Your payout line items show what actually moved.

Two other costs can hit UK merchants. If the customer paid on a card from another country, Shopify says small currency adjustments can apply to the chargeback amount, separate from the fee. And your own time counts. Understanding how chargebacks work in practice means pricing the whole loss. Our true cost of a chargeback calculator lets you put an hourly figure on it, and the example above shows why the £10 rarely tells the whole story.

What does a UK chargeback do to your chargeback rate?

Your chargeback rate is the number of chargebacks in a month divided by the number of eligible transactions in that same month. Shopify uses it to judge your account, and card networks use their own versions. A rate that climbs can put your store under monitoring or restrict features.

Shopify's help page is blunt about one thing: winning a dispute doesn't remove it from your rate. The rate counts disputes filed, not outcomes. It is how the UK chargeback process shows up in your account standing.

Here is an illustration of how UK chargebacks are counted. Say you take 400 eligible transactions in a month and receive 3 chargebacks. Your rate is 3 divided by 400, which is 0.0075, or 0.75%. If you win 2 of the 3, the rate is still 0.75%, because all 3 were filed.

Shopify also publishes two versions of the rate. The standard rate leaves out disputes resolved automatically through network dispute resolution programmes. The version that includes them is the one Shopify uses for account warnings, reserves and standing. For thresholds, the Visa and Mastercard figures and when to act, see our chargeback rate calculator and thresholds guide.

Who decides who wins, and what do they look at?

The issuer and the card company decide, working from the evidence in front of them. Shopify's guidance says reviewers handle a high volume of disputes and may spend only a few minutes on each, which is why the first thing they see should be your strongest proof.

Anyone asking how chargebacks work in the UK ends up at this question sooner or later. The answer is a bank, not Shopify and not you, which is why the chargeback scheme rewards clear files over long ones.

Three habits from Shopify's guidance make a measurable difference to how a response reads:

Put direct proof first, and keep policy documents for later.
Use screenshots of tracking pages and messages instead of links, because reviewers can see a screenshot without opening another system.
Label each item. "Order confirmation email sent on 2 October 2026, showing a total of £84.00" beats "attached screenshot".

Shopify is also candid that strong evidence improves your odds but doesn't guarantee a win, and under the chargeback scheme banks keep their discretion. Banks can rule for the customer even when you provide delivery confirmation. One merchant on the Shopify Community lost a £1,747.25 dispute despite 3D Secure, a signature and tracking. That is one anecdote, not a rule, but it shows that a complete file can still lose.

If the customer never contacted you before going to their bank, say so. Shopify suggests including evidence that no support request was received, your contact details and a note that you would have fixed the issue if given the chance.

What's different for UK merchants?

How chargebacks work in the UK follows the same card scheme process as anywhere else, but several local rules shape the customer's side of it and the way you handle yours. This section is general information, not legal advice.

How does the UK fee compare with other countries?

Shopify lists the UK dispute fee at £10, returned if you win. That is lower than in several other Shopify Payments countries: the US and Canada are $15, the euro area is €15, Australia is A$25 and New Zealand is NZ$20. Ireland is €15 plus 23% VAT. Shopify's overview page words the fee refund slightly differently by country, so check your payout line items after a win.

Do debit cards have chargebacks in the UK, and what about credit cards?

For debit cards, MoneyHelper says the chargeback scheme covers all purchases, and the customer has 120 days from the purchase date to claim. If the purchase is for something in the future, such as event tickets, the 120 days start from the day the event would have taken place.

For credit cards, the route depends on the price. Either way, the issuer and acquirer follow the same scheme process behind the scenes; only the customer's protections differ. MoneyHelper says purchases over £100 and up to £30,000 can be claimed under Section 75 of the Consumer Credit Act, with no time limit. For other amounts, the customer has 120 days to claim a chargeback.

What is Section 75, and does it affect me?

Section 75 makes the credit card company equally responsible with the seller when something goes wrong, such as goods that never arrive or aren't as described. It covers a single item costing over £100 and up to £30,000, and a deposit paid on a credit card can bring the whole price within it.

It is a legal right, whereas chargeback is a scheme arrangement. The chargeback scheme itself is voluntary and sits on top of it. MoneyHelper also notes that Section 75 now extends to many third-party Buy Now Pay Later products taken out on or after 15 July 2026. That includes providers such as Klarna and Clearpay, but not a BNPL product offered directly by a retailer. How a Section 75 claim reaches you as a merchant, and how it differs from a chargeback in practice, is the subject of our Section 75 guide.

Which consumer rules shape refunds and returns?

GOV.UK says online sellers must tell customers they can cancel up to 14 days after delivery. If you don't tell them, they can cancel at any time for the next 12 months. Once a customer has told you they want to cancel, they have a further 14 days to send the goods back, and you refund within 14 days of receiving them, including standard delivery.

The rules are tighter than many stores realise, and a clear returns page prevents a lot of disputes. We cover them in our Consumer Contracts Regulations guide.

Do SCA and 3D Secure matter in the UK?

Yes. Strong Customer Authentication rules have applied under the Payment Services Regulations 2017 since 14 September 2019, according to the FCA. In practice, 3D Secure is the checkout step that delivers it. A successful 3D Secure check can move liability for fraud chargebacks to the issuer, but it doesn't cover other dispute types. UK and EU Shopify Payments has it built in, used when the issuing bank requires it. Our 3D Secure and chargebacks guide goes through the limits.

What proof of delivery do UK carriers give?

Royal Mail captures a photo on delivery for Tracked 24 and Tracked 48 where no signature is needed. Evri offers a Digital Signature add-on with photographic proof, priced at 60p at the time we checked, though prices change. We haven't verified what proof DPD provides, so check with the carrier before relying on it. Our UK carriers and proof guide has the detail.

Do UK bank holidays change the deadline?

How weekends and bank holidays affect a Shopify due date isn't covered in the sources reviewed. The safe approach is to treat the date in your admin as hard and file early, especially when a bank holiday sits inside your window.

Can a merchant stop a chargeback before it happens?

You can't stop every UK chargeback, because customers keep the right to dispute a payment whatever you do. You can make most of them less likely, and you can make the ones that arrive easier to win. The aim is fewer surprises and a better file.

The bank call comes first in the UK chargeback process, so prevention pays most before it, not after. Shopify's own prevention advice comes down to four habits: clear product descriptions, proactive shipping updates, quick replies to customer messages and a visible refund policy. Add these, which follow from the steps above:

Use tracked delivery on every parcel, and signature or photo proof on high-value orders.
Make your billing name recognisable, so customers don't mistake your charge for fraud.
Reply to complaints within a day, because an angry email today is a chargeback next week.
Keep every customer conversation in one place, so you can screenshot it later.
Show your returns and cancellation terms at checkout and in the confirmation email.
Review each lost dispute for a cause, not only a verdict.

Disputes where the customer has genuinely forgotten or is trying to keep the goods and the money are a separate topic, and our friendly fraud guide for UK stores deals with them.

A day-by-day plan for the first seven days after a UK chargeback

Treat the due date as a project deadline, not a sudden event. This plan uses a 14 day window from Monday 12 October 2026 as an illustration, and the days will shift with your own due date. The UK chargeback process rewards merchants who start early, because the money has already left.

Day	Date	What to do
0	Monday 12 October	Open the dispute. Note the reason, amount, order number and due date.
1	Tuesday 13 October	Screenshot the order, payment and tracking pages. Check for any refunds already sent.
2	Wednesday 14 October	Gather messages with the customer and your policies. Check whether they ever contacted you.
3	Thursday 15 October	Decide whether to fight or accept, using the true cost maths above.
4	Friday 16 October	Draft your cover note using the template below.
5 and 6	Weekend	Nothing due. Rest.
7	Monday 19 October	Label every exhibit and put the strongest first.
8 and 9	20 and 21 October	Read it once more as a stranger would. Fix gaps.
11	Friday 23 October	Submit. Three days of margin before Monday 26 October.

One caution, stated once: the time of day and time zone of the due date aren't covered in the sources reviewed. Don't plan to submit in the final hours. If you do nothing, Shopify submits whatever is on file for you on the due date, so a response goes in, but it may be thinner than yours would have been.

Copy-and-paste templates

These are starting points. Replace the square brackets with facts from your records, and leave out any line you can't support. A good response in the UK chargeback process is short, dated and easy to check.

Cover note for the response

Common mistakes

Most errors in the UK chargeback process are small and avoidable. These eight come up most.

Mixing up chargeback vs refund. A refund is your decision, but by the time a chargeback notice arrives the money has already moved, and a polite email to the customer doesn't stop the clock. Respond in the admin.
Assuming Shopify will win it for you. Shopify files a response on the due date if you add nothing, but it only contains what is already in your records, and it isn't involved in the decision.
Sending a pile of unlabelled screenshots. A reviewer with a few minutes can't work out what each one proves. Name every item and put the best one first.
Leading with policy when the dispute is about delivery. A returns policy doesn't prove a parcel arrived. Match the evidence to the reason.
Arguing with the customer in your response. State dated facts and let the exhibits do the work.
Refunding without checking. How a refund interacts with an open dispute isn't covered in the sources reviewed, so ask Shopify Support first.
Relying on 3D Secure alone. In UK chargebacks it covers fraud disputes only, and a merchant can still lose with it in place.
Never logging outcomes. Without a log you fight the same chargeback again and again.

FAQ

What is a chargeback?

A chargeback is a card payment reversed by the customer's bank after they dispute it. The bank takes the money back through the card scheme and you are left to prove the sale was genuine. It differs from a refund, which you choose to send yourself.

How do chargebacks work in the UK for Visa and Mastercard?

The overall path is the same: dispute, chargeback, response, review, decision. Reason categories, evidence needs and some timings can differ by scheme and dispute type. Shopify also notes that disputes from third-party payment providers may follow other processes and timelines, so check the provider's own guidance.

Who pays for a chargeback?

You do, unless you win. The disputed amount and a processing fee are taken from you when the chargeback opens. If you win, both come back. Shopify says it isn't liable for chargebacks that occur on its platform, so don't expect Shopify to cover a loss.

How long does a chargeback take in the UK?

Expect roughly 7 to 21 days to respond, then up to 75 days for the card company to rule once you have submitted. Add the time before the notice reaches you, and a single dispute can run for around three months. Inquiries tend to run 65 to 75 days.

Can a merchant stop a chargeback?

Not once the customer has disputed the payment. You can contest it with evidence, or accept it. What you can do is reduce the chance of one by delivering with proof, using a clear billing name and replying quickly to complaints. A fast refund before a dispute opens also avoids the process entirely.

What is representment?

Representment is your formal reply to a chargeback. You send evidence through your payment provider to the issuer, arguing that the transaction was valid. On Shopify, you do it on the order's chargeback form, ideally with labelled exhibits and the strongest proof first.

What happens if you lose a chargeback?

You lose the disputed amount and the fee, and there is no appeal. Shopify says its decision can't be overturned. The dispute also stays in your chargeback rate. Log the cause, fix what you can and use the case as a prompt to tighten your delivery proof or policy wording.

Is a chargeback the same as a refund?

No. In the chargeback vs refund comparison, a refund is your own decision to return money, while a chargeback is the customer's bank forcing the reversal under card scheme rules. It carries a fee and a mark on your chargeback rate, so if a refund is the right outcome, sending it early is usually cheaper than a dispute.

Do debit cards have chargebacks in the UK?

Yes. MoneyHelper says chargeback protects all debit card purchases, and a claim generally has to be made within 120 days. Section 75 is different: it covers credit cards only, for purchases over £100 and up to £30,000. Debit card customers rely on chargeback alone.

Does winning clear a dispute from your record?

Not from your chargeback rate. Shopify says the rate counts disputes filed, so a win returns the money and fee but the dispute still counts. Keep your evidence, because a customer's bank can dispute the same transaction again after you win.
