UK card chargebacks in 2026

A chargeback is a forced reversal of a card transaction initiated by the customer's card issuer, usually after the customer disputes the transaction. The customer gets their money back, the merchant loses the transaction value, and the merchant typically pays a non-refundable chargeback fee on top.

Chargeback fees in 2026 typically run £15 to £35 per case regardless of outcome. Stripe charges £15 (refunded if the merchant wins the dispute). Worldpay £20. Adyen £20 to £50 depending on plan. Dojo £25. SumUp £25. Square £25. The merchant pays the fee even when they win the dispute, except where the acquirer explicitly refunds it.

Stage 1: customer files dispute with their card issuer. Stage 2: issuer initiates chargeback via Visa or Mastercard rails, money is provisionally pulled from the merchant. Stage 3: merchant has 7 to 21 days (varies by reason code) to submit evidence challenging the dispute. Stage 4: acquirer reviews evidence and either accepts (merchant loses) or represents (challenges back). Stage 5: if represented, issuer can accept (merchant wins) or escalate to pre-arbitration. Stage 6: pre-arbitration to arbitration with Visa or Mastercard as final arbiter. Total elapsed time: 30 to 120 days typically.

Friendly fraud is when a legitimate customer disputes a transaction they actually authorised. Most common reasons: customer forgets the transaction, family member makes the transaction, customer regrets the purchase but cannot get a refund through normal channels, customer claims item not received when it was received. Friendly fraud is estimated at 60 to 80 percent of UK online chargebacks in 2026, up from 40 to 50 percent pre-pandemic.

For card-not-present (online) disputes: provide SCA / 3DS2 authentication evidence (this alone wins most "I did not authorise" disputes due to liability shift), delivery proof with signature, customer correspondence showing service delivery, IP address matching, billing-shipping match, and clear refund policy that the customer agreed to. For card-present (in-person): provide signed receipt, EMV chip-read evidence, and POS authorisation log. Cases with SCA completion are almost always winnable.

Visa monitors merchants exceeding 0.9 percent chargeback ratio or 100 chargebacks per month. Mastercard monitors at 1.5 percent or 100 monthly. Merchants in monitoring face higher fines (£25 to £100 per chargeback), mandatory remediation plans, and potential acquirer termination. High-risk verticals (CBD, vape, gambling, adult, dating) face lower thresholds and stricter monitoring.

Yes, mostly. Pre-emptive refunds (refund the customer before they dispute) cost less than chargebacks. Clear billing descriptors (so customers recognise the transaction on their statement) reduces "I do not recognise this" disputes. Proactive customer service (email confirmation, dispatch notification, delivery confirmation) reduces "item not received" disputes. Fraud prevention tools (Stripe Radar, Adyen RevenueProtect, Sift) intercept fraudulent transactions before authorisation. SCA enforcement removes most "I did not authorise" disputes.

A refund is voluntary, initiated by the merchant, with funds returned via the original transaction. A chargeback is forced, initiated by the issuer, with funds reversed via the card scheme rails. Refunds cost the merchant the original interchange (most acquirers do not refund their take); chargebacks cost the merchant the full transaction value plus a non-refundable fee. Refunds are always cheaper than chargebacks.
