How to reduce card processing fees
Beyond picking a cheaper provider, there are concrete, sourced tactics that reduce what you actually pay — some save a few pounds a month, others meaningfully more at volume.
1. Switch pricing model once volume justifies it
Move from flat-rate to interchange-plus once you're processing roughly £10,000–£15,000/month — see our flat-rate vs interchange-plus guide for the full breakdown.
2. Negotiate the markup — the only negotiable line
Interchange and scheme fees are fixed by regulation and the card networks. Only the processor's own markup is up for discussion — businesses with rising or steady volume have real leverage here.
3. Avoid unnecessary monthly minimums and bundled fees
Statement fees, non-compliance penalties and "reporting access" charges can silently add £50-£150/month on some accounts. Many are waivable — ask directly.
4. Stay PCI DSS compliant
Non-compliance fees are a common add-on specifically to penalise merchants who haven't completed their PCI self-assessment questionnaire. Completing it (usually free or low-cost) removes the surcharge.
5. Use Level 2/3 data for B2B transactions
Supplying enhanced line-item data (tax amount, PO reference, item detail) on commercial-card transactions can qualify them for materially lower interchange — industry estimates suggest roughly 50-150 basis points lower. Note: Visa retired its standalone Level 2 programme on 18 April 2026 in favour of a newer Commercial Enhanced Data Program.
6. Avoid manual key-entry where possible
Keyed-in and card-not-present transactions carry higher fraud risk and sit in pricier interchange/scheme-fee tiers than chip/PIN or contactless. Use a proper card reader, not manual entry, whenever you can.
7. Settle batches promptly
Settling the same day avoids "downgrades" to non-qualified, higher-interchange tiers that some networks apply to late-settled transactions.
8. Actively reduce chargebacks
UK merchants typically pay £15-£25 per chargeback (up to £150 in some cases) on top of the lost sale. Crossing dispute-ratio thresholds (0.9% Visa, 1.5% Mastercard) triggers monitoring with higher fines. Use Address Verification, 3D Secure, and clear refund policies — friendly fraud accounts for an estimated 60-80% of UK online chargebacks.
9. You can't pass card fees on to consumers
Since 13 January 2018 (Payment Services Regulations 2017), UK businesses are legally barred from surcharging consumers for card or card-wallet payments. This is still permitted on business/commercial cards.
10. Consider Open Banking/Direct Debit for invoiced payments
For B2B or recurring invoiced payments where card acceptance isn't essential, account-to-account rails (via providers like GoCardless or TrueLayer) avoid interchange and scheme fees altogether.
11. Ask your acquirer for interchange transparency data
UK acquirers are required to give merchants data on the cost of accepting different card brands/categories — use it to see which card types actually drive your costs, and steer customers toward cheaper ones where you can (steering is allowed; surcharging consumers is not).
Frequently asked questions
