UK Cross‑Border Card Fees: Cap Incoming?

What’s new — On 15 Jan 2026, the UK High Court upheld the Payment Systems Regulator’s authority to cap UK‑EEA online (card‑not‑present) interchange fees (now ~1.15% debit / 1.5% credit). The PSR earlier found limited competition and estimated £150m–£200m/year extra costs to UK merchants after post‑Brexit hikes. The regulator dropped an interim cap but is developing the long‑term cap methodology. [lawyer-monthly.com], [psr.org.uk], [hsfkramer.com]

Why it matters for SMBs — If you sell online to EU customers (or via EU‑issued cards), a cap would directly reduce your blended card costs—or strengthen your hand when negotiating acquirer markups and scheme fees. [psr.org.uk]

What to watch (next 1–2 quarters)

  • PSR consultation updates on the cap’s level (EU‑IFR‑like 0.2%/0.3% has been floated) and start date. [lexology.com]
  • Acquirer communications (pass‑through timing).
  • Networks’ potential non‑price changes (e.g., scheme fees) that could offset caps—scrutinise MDR statements. [psr.org.uk]

Suggested actions now

  1. Tag transactions by issuer region to quantify UK–EEA CNP volume and current effective interchange/MDR. (Sets your savings baseline.) [psr.org.uk]
  2. Add an A2A/Pay‑by‑Bank option for EU buyers where instant rails + VoP are mandated; compare acceptance cost vs cards. [finextra.com]
  3. Prepare a renegotiation pack with your acquirer to trigger pricing reviews upon cap announcement. [psr.org.uk]
