A chargeback can cost you the sale, the stock, and a hefty fee on top. Here is how the major UK payment providers handle disputes, and what that really costs your business.
A customer buys a £380 camera lens from your shop. It arrives safely, you have the signed delivery receipt, and the transaction was chip-and-PIN. Six weeks later, your payment provider emails you: the customer has filed a dispute claiming they never received it. You now owe the money back, you have a fee on top, and you have two weeks to gather evidence and submit it through a system you have never used before.
This is what a chargeback actually looks like in practice. Not a theoretical risk. Not fine print. A real event that happens to tens of thousands of UK merchants every year, often at the worst possible time.
According to the UK Finance Payment Markets Summary, card fraud and disputes represent a growing operational burden on smaller businesses, with friendly fraud (where a genuine customer disputes a legitimate transaction) now accounting for a significant and rising share of all chargebacks. Javelin Strategy estimates that for every £1 in actual fraud chargebacks, merchants lose an additional £2.40 in related costs including fees, operational time, and lost stock.
So how your payment provider handles chargebacks is not a minor footnote. It is a material business cost. Let us look at what you are actually getting from the major UK providers.
A chargeback is a forced reversal of a card transaction, initiated by the cardholder's bank. The customer contacts their bank, claims a problem with the transaction (fraud, non-delivery, item not as described, or simply a duplicated charge), and the bank pulls the funds back from you while the dispute is investigated.
Cardholders have significant protection under the rules set by Visa and Mastercard, as well as Section 75 of the Consumer Credit Act for purchases over £100 on credit cards. These protections exist for good reason. But they also create a system that merchants sometimes find heavily weighted against them, particularly smaller businesses without dedicated finance teams.
The result: UK merchants lost an estimated £1.3 billion to chargebacks in 2023, according to data referenced in the Chargebacks911 Global Disputes Index. And the administrative cost of fighting them eats further into already thin margins.
Worldpay is the largest payment processor in the UK by volume, handling transactions for roughly 400,000 merchants across the country. Its scale means it has established dispute management infrastructure, and for large enterprise clients, dedicated account support is part of the package.
For smaller merchants, the picture is different. Worldpay charges between £15 and £25 per chargeback, depending on your contract and merchant category. The dispute process is managed through its online merchant portal, and guidance is available, but human support for SME chargeback cases is inconsistent. Merchants on standard contracts frequently report being directed to self-serve resources rather than speaking with someone who can actively guide them through evidence submission.
Worldpay does provide some fraud prevention tools, including 3D Secure and risk scoring, which is genuinely useful at the prevention stage. But once a dispute is filed, the experience for a small business owner who does not deal with these regularly can feel opaque.
Honest assessment: Strong enterprise infrastructure, less consistent SME support. Fee range is similar to or slightly below Teya depending on your contract tier.
SumUp has built a substantial UK merchant base among micro-businesses and sole traders, largely because of its low entry cost and simple hardware. Its approach to chargebacks reflects that simplicity: the process is automated and largely self-serve.
SumUp does not publish a specific chargeback fee in its standard UK pricing page. Merchants report that disputes are handled via email notifications and a portal workflow. There is no clearly advertised dedicated dispute team, and the emphasis is on speed and automation rather than guided human support.
For a merchant selling £20 crafts at a market, this is probably fine. For a merchant with a £1,200 disputed transaction and a box of evidence to assemble correctly, the absence of guided support is a meaningful gap.
Honest assessment: Works adequately for low-value, low-volume disputes. Not built for businesses where chargebacks carry significant financial weight.
Square offers what it calls a Dispute Centre within its dashboard, and it deserves credit for making the interface genuinely clear. When a dispute is filed, Square notifies you, explains the reason code, and walks you through what evidence is acceptable. The Dispute Centre is probably the best self-serve interface in this comparison.
Square does not publicly list a specific chargeback fee for UK merchants (its fee structure in the UK is simpler than in the US market). However, the resolution process remains largely self-serve. Square does offer a chargeback protection programme in some markets, but this is not currently a standard feature for UK merchants in the same form as it exists in the United States.
For merchants comfortable with technology and organised with their documentation, Square's Dispute Centre is a reasonable tool. For merchants who want a human being to look at their case and tell them what to submit and how, it falls short.
Honest assessment: Best self-serve dispute interface among the challengers. Limited human support remains the gap.
Barclaycard occupies a different part of the market: it is primarily a bank-based acquiring relationship rather than a standalone payment technology provider. That brings certain advantages, including the backing of a major financial institution and established dispute processes that follow Visa and Mastercard scheme rules precisely.
The disadvantage is complexity. Barclaycard's dispute process involves multiple internal departments, and smaller merchants frequently describe it as slow and difficult to navigate without a dedicated finance contact. Chargeback fees vary by contract and are not transparently published for SME merchants. The process can involve phone calls, paper submissions, and waiting periods that are frustrating for businesses running on tight cash flow.
Barclaycard does offer fraud prevention tools including 3D Secure and, for larger merchants, risk management services. But the dispute resolution experience for an independent retailer or hospitality business is not where the product shines.
Honest assessment: Reliable and scheme-compliant, but process complexity and lack of transparent pricing make it harder to recommend for SMEs who need straightforward dispute support.
Teya charges a flat £20 per chargeback. That is the fee, stated clearly, with no range depending on your contract tier or merchant category.
More important than the fee is what happens after it. Teya operates a four-stage dispute process with a dedicated team that actively guides merchants through evidence submission. This is not a self-serve portal with a FAQ link. It means a team who reviews your case, tells you what documentation is needed, and helps you submit a dispute response that gives you the strongest possible chance of winning.
The dispute window is 120 days, which aligns with Visa and Mastercard scheme rules. Within that window, Teya's team works with you through each stage: the initial dispute notification, the evidence gathering phase, the formal response submission, and the resolution.
On the prevention side, Teya provides pre-authorisation capability (useful for deposits, holds, and high-value transactions), digital receipts, and proof of delivery documentation support. These are not afterthoughts. They are the evidence base you need if a dispute is ever filed, and having them in order before a dispute arises is the difference between winning and losing.
Refunds, when needed, can be issued directly from the Teya terminal, the Teya app, or the merchant portal. This operational flexibility matters when you need to process a refund quickly to prevent a dispute from escalating in the first place.
Let us return to our camera shop scenario. A customer disputes a £380 transaction, claiming non-receipt.
Without strong support: You receive an automated email, log into a portal, attempt to work out which evidence to submit from a dropdown list of categories, upload what you think is relevant, and wait. If you submit the wrong evidence or miss a procedural step, you lose by default, not on the merits of your case.
With Teya's approach: You receive the dispute notification, your dedicated team contacts you, reviews the transaction, and tells you specifically: you need the signed delivery confirmation, the transaction receipt showing chip-and-PIN authorisation, and any written communication from the customer acknowledging receipt. You submit the right evidence in the right format. Your chances of winning increase substantially.
The £20 fee is the same either way. The outcome is not.
| Provider | Chargeback Fee | Human Support | Prevention Tools | Self-Serve Interface |
|---|---|---|---|---|
| Teya | £20 flat | Dedicated team, 4-stage guided process | Pre-auth, receipts, proof of delivery | Yes, plus human guidance |
| Worldpay | £15-£25 | Inconsistent for SMEs | 3D Secure, risk scoring | Yes |
| SumUp | Not publicly listed | Automated, minimal human contact | Basic | Yes |
| Square | Not publicly listed (UK) | Self-serve Dispute Centre | 3D Secure | Yes, best in class |
| Barclaycard | Varies by contract | Multi-department, complex process | 3D Secure, enterprise risk tools | Limited |
Chargebacks are not a rare event for most merchants. If you process more than a few hundred card transactions per month, you will encounter them. The question is not whether you will face a dispute; it is whether you will be equipped to fight it.
A few practical steps regardless of which provider you use:
On fee alone, the difference between providers is relatively small. A £20 fee versus £22 is not a deciding factor for most businesses.
What matters is the support architecture around that fee. A chargeback you fight and lose costs you the transaction value, the fee, and in many cases the stock. A chargeback you fight and win costs you only the fee and some time. The quality of guidance you receive determines which outcome is more likely.
Square deserves genuine credit for building the most user-friendly self-serve dispute interface in this comparison. For organised merchants who are comfortable navigating these processes independently, it is a solid option.
But for most independent retailers, hospitality businesses, and service providers who deal with occasional disputes and need someone to actually help them through the process, the combination of a transparent flat fee and a dedicated human team represents a meaningfully different proposition. Not a marginal one.
Chargebacks are stressful. They should not also be confusing.
