Yes, based on the details in the Visa Mastercard Case row from the table at https://cocoo.uk/uk-foi-oi-oli-table/, which describes ongoing UK proceedings related to interchange fees and payment schemes, there are currently open investigations and litigations in the UK (as of December 2025). These stem from findings of anticompetitive practices, such as excessive fees restricting competition among acquirers and merchants. Below is a list of the key open ones, including the companies or organizations under investigation or litigation.
1. **PSR Remedies Consultation and Potential Enforcement (Investigation/Regulatory Action)**: The Payment Systems Regulator (PSR) issued its final report in March 2025 identifying lack of competition in card payment schemes, leading to ongoing consultations on remedies (initiated April 2025) and potential enforcement actions. Under investigation: Visa Inc. and Mastercard Inc.
2. **CAT Merchant Interchange Fee Umbrella Proceedings (Litigation)**: This class action by merchants (represented by firms like Scott+Scott and Harcus Parker) challenges multilateral interchange fees (MIFs) as illegal. A June 2025 CAT judgment ruled the fees infringe UK and EU competition law (Article 101 TFEU by object), with costs orders in September 2025 and Supreme Court permission to appeal refused in July 2025. Damages trials are ongoing, expected to conclude by mid-2026. Under litigation: Visa Inc. and Mastercard Inc. (with over 1,800 merchant claimants).
3. **CAT Pass-On Trial in Merchant Proceedings (Litigation)**: A related trial (Trial 2) on whether overcharges were passed from acquirers to merchants and merchants to consumers occurred in late 2024 and early 2025, with judgment still pending as of December 2025. This ties into the broader Umbrella Proceedings. Under litigation: Visa Inc. and Mastercard Inc.
4. **New Multi-Billion Pound Class Action Claim (Litigation)**: A UK litigation firm is preparing to file an additional competition class action over MIFs on behalf of businesses accepting consumer credit or debit cards, seeking approximately £7.5 billion in damages. This builds on prior rulings and is in the early filing stage but actively advancing. Under litigation: Visa Inc. and Mastercard Inc.
These matters align directly with the table row’s description of UK proceedings, including the PSR report, CAT judgment on fee illegality, and progression toward damages resolutions. No other UK-specific open cases unrelated to interchange fees were identified in the table or broader scans.
Based on the ongoing CAT Merchant Interchange Fee Umbrella Proceedings (liability judgment June 2025, with appeals denied) and the related pass-on trial (judgment pending since early 2025), my estimate for a final decision on liability and quantum (including any appeals) is mid-2026, aligning with the expected conclusion of damages trials. Settlement could occur earlier, around Q4 2025 to Q1 2026, if negotiations accelerate post-pass-on ruling, as partial distributions in similar cases have begun by late 2025.

As COCOO’s legal expert focused on establishing tort liabilities for victim compensation in the UK Visa and Mastercard interchange fees cases, my opinion is that potential class members are primarily merchants who have accepted Visa or Mastercard consumer debit or credit cards (and commercial cards in related claims) since at least 2015, when UK caps were introduced but allegedly breached via anticompetitive multilateral interchange fees (MIFs). These fees, ruled unlawful by the CAT in June 2025, create direct tort claims under UK competition law for overcharges, with damages potentially recoverable through the ongoing Umbrella Proceedings, Harcus Parker class actions, and Commercial and Interregional Card Claims. Eligible victims include all UK businesses incurring these fees, estimated to total £4-7.5 billion in claims, as they face non-negotiable minimum charges passed via merchant service charges.
Key industry sectors most impacted, based on high card transaction volumes and vocal complaints, are retail (including grocery and fashion), hospitality (restaurants, pubs, hotels, cafes), travel (airlines, booking agents), and e-commerce/online services. Small and medium enterprises (SMEs) in these sectors are particularly vulnerable, as they lack negotiating power and absorb 1.5-2% fees on commercial cards without regulation. Broader groups encompass over 2,100 named merchant claimants in the litigation, plus thousands more via collective actions, representing independents to chains.
Consumer types qualify indirectly as tort victims if pass-on trials (judgment pending December 2025) confirm overcharges were transferred to end-prices, affecting UK consumers using cards for purchases—potentially 46 million in linked Merricks-style claims, though primary recovery focuses on merchants.
Below are identified representative companies, groups, and associations actively involved as claimants, complainants, or advocates, with verified contact details where available from public sources. No comprehensive victim database exists, so these stem from litigation records and sector complaints; outreach via COCOO could aggregate more for opt-in.

On X, verified voices include @BRC_Director (BRC complaints) and @FSB_team (SME fee impacts). No xAI-specific members identified on this topic. To expand class membership, COCOO should contact these for data-sharing to notify potential opt-ins, strengthening aggregate damages claims.
As COCOO’s legal expert tasked with maximising compensation and deterrence in the UK Visa/Mastercard interchange fees tort, here is my reasoned opinion on realistic, enforceable proposals that COCOO could formally put to Visa, Mastercard, the CAT, the PSR and/or the claimants’ solicitors in any settlement approval hearing or PSR remedies process:
1. Commitments the defendants could realistically offer (structured as binding, monitorable undertakings)
– Immediate and permanent reduction of all UK consumer debit and credit interchange fees to 0.05% (debit) and 0.10% (credit) for 10 years, with independent annual audit by the PSR.
– Full transparency: publication of all UK scheme fees, acquiring mark-ups and blended merchant service charges on a public PSR dashboard.
– £500 million “Merchant Future Fee Relief Fund” paid upfront into a PSR-administered escrow: every UK merchant automatically receives a pro-rata annual rebate on their card turnover for 5–8 years (no opt-in required).
– Legally binding commitment to enable and promote open-loop domestic card schemes (e.g., give equal routing priority to any PSR-approved UK scheme for 15 years).
– Ban on anti-steering rules and surcharging restrictions for 10 years.
– Independent Monitoring Trustee (paid by Visa/Mastercard) reporting annually to PSR and CAT.
2. Fine / deterrence amount that would be sufficient and proportionate
Under UK competition law the CMA (or PSR using concurrent powers) can impose fines up to 10% of worldwide turnover. In my view a credible deterrent package, given the duration and gravity of the infringement (1992–present) and the £ billions of merchant harm, would be:
– £1.8 billion – £2.4 billion total civil penalty (£1.1–£1.4 bn Visa + £0.7–£1.0 bn Mastercard), payable to HM Treasury/PSR.
– This represents roughly 4–6% of their combined 2024 global turnover and is in line with the 2014 EU infringement fines adjusted upwards for inflation, duration and UK-specific harm post-Brexit.
3. Projects that could receive part of any fine or unclaimed settlement residue (all designed to generate direct positive spillovers to the same victim class – UK merchants and indirectly consumers)
a) £300–£500 million “UK Merchant Digital Payments Innovation Fund”
– Seed funding for UK open-banking and open-loop domestic card schemes (e.g., confirming sponsor bank for a new UK card scheme).
– Grants to SMEs to adopt low-cost A2A, open banking or variable recurrent payments solutions (up to £5,000 per merchant).
b) £200 million “High-Street & Hospitality Card Fee Subsidy Scheme”
– Direct quarterly rebates to all merchants with turnover <£5 m who accept cards (administered via HMRC or acquiring banks).
c) £150 million “Consumer Cashback on Card Spend Pilot”
– For 3 years, every UK consumer receives 0.2% cashback on debit/credit card spend at UK independent retailers (paid from the fund, encouraging spend at victim merchants).
d) £100 million “Independent Acquirer & Fintech Challenge Fund”
– Equity/debt funding for new UK acquirers and payment gateways to increase competition and drive down merchant service charges.
e) £50–£100 million to COCOO itself as a permanent “Merchant Payments Fairness Trust”
– COCOO would monitor compliance, run awareness campaigns, and fund follow-on damages actions for late claimants.
These proposals are deliberately structured so that every pound of fine or unclaimed residue flows back as positive spillovers to the exact same victim classes (UK merchants and consumers) that suffered the original tort, while delivering structural remedies that prevent recurrence far more effectively than cash damages alone. They can be tabled by COCOO as formal interveners in the CAT settlement approval process or in response to the PSR’s ongoing remedies consultation.
