Chargeback Outsourcing for UK Merchants: Complete Guide 2026

Quick answer

UK merchants follow the same Visa/Mastercard chargeback rules as US merchants — rules are set by the card networks, not UK law. ChargeMate handles UK disputes in GBP, works with Revolut Business, Barclays, NatWest, Lloyds, Stripe UK, Worldpay, and all other UK processors without API integration. From £8/case equivalent.

The biggest challenge for UK merchants seeking chargeback outsourcing: most major services are US-centric and only support US processor APIs. Chargeflow and Disputifier don't support Revolut Business, Worldpay, or Barclays Merchant Services — the three most common UK processor setups. ChargeMate's no-integration approach covers every UK processor.

UK-Specific Chargeback Rules

Visa VAMP (UK merchants)

UK merchants are subject to Visa's VAMP monitoring program on the same 0.9% Excessive threshold as all Visa merchants globally. The calculation uses transactions processed by your UK acquirer. UK merchants with high eCommerce volume should track weekly to avoid threshold breach.

Mastercard MCMP (UK merchants)

UK Mastercard disputes follow the same 1.5% monitoring threshold. Mastercard is less dominant in the UK than Visa, so MCMP thresholds are less commonly hit by UK merchants.

Section 75 — CCA 1974

Section 75 of the Consumer Credit Act gives credit card holders the right to claim against the issuing bank for purchases between £100–£30,000 where there's a misrepresentation or breach of contract. Section 75 claims are separate from Visa/Mastercard chargebacks — they go directly through the issuing bank. Merchants have no formal response process for Section 75 — only the bank and merchant negotiate. Note: Visa/Mastercard debit cards are NOT covered by Section 75.

Response deadlines (same as US)

Visa: 30 days from dispute notification. Mastercard: 45 days. Amex: 20 days. Discover: 30 days. These deadlines are set by the card networks globally — UK merchants have the same response windows as US merchants.
