Stripe is the best payment gateway for most UK businesses in 2026. It’s fully SCA-compliant, supports GBP natively, handles UK VAT via Stripe Tax, and has the best developer API in the industry. For businesses that rely heavily on direct debit, GoCardless is the UK-specific specialist worth considering.
UK Payment Gateway Comparison
Stripe (UK)
Fees: 1.5% + 20p for UK cards. 2.5% + 20p for European cards. Additional fees for international cards.
Stripe’s UK fees are lower than its US pricing (1.5% vs 2.9%) because European interchange rates are regulated. This makes Stripe even more attractive for UK-based SaaS and e-commerce.
SCA compliance: Stripe handles Strong Customer Authentication (SCA) automatically with 3D Secure 2. No manual implementation required — Stripe’s checkout and payment intents handle the authentication flow.
UK VAT: Enable Stripe Tax and it calculates and collects UK VAT (20% standard rate) on every eligible transaction automatically.
Best for: SaaS, e-commerce, service businesses, marketplaces.
GoCardless
Fees: 1% + 20p per transaction (capped at £4). Pro plans with lower rates available.
GoCardless specialises in direct debit — bank-to-bank payments via Bacs (UK) and SEPA (Europe). For subscription businesses with UK customers, direct debit has significantly lower failure rates than card payments (0.5% vs 5%+) because bank accounts don’t expire.
Best for: Subscription businesses, gyms, membership organisations, B2B recurring billing where customers prefer not to use cards.
Limitation: Card payment is not GoCardless’s strength — for one-time or card payments, you still need Stripe alongside it.
Square
Fees: 1.75% for in-person payments. 2.5% for online payments. No monthly fee.
Square is the easiest option for physical retail and in-person payments. The hardware (card reader, terminal) is well-designed and the dashboard is simple. Less suitable for online-only businesses.
Best for: Cafes, restaurants, market stalls, pop-ups, and retail businesses that primarily take in-person payments.
Checkout.com
Fees: Custom pricing. Typically negotiated for volume above £50K/month.
Checkout.com is an enterprise-grade payment processor with competitive rates at scale. Used by major UK businesses and fintechs. The onboarding process is more involved than Stripe.
Best for: High-volume UK businesses (£1M+ annual payment volume) where negotiated rates justify the complexity.
PayPal (UK)
Fees: 2.9% + 30p for online transactions. Higher for cross-border.
PayPal has strong brand recognition with UK consumers, particularly for older demographics. The API is significantly worse than Stripe. Chargeback rates are higher. We recommend PayPal as a secondary payment option only, not a primary gateway.
SCA (Strong Customer Authentication)
Since September 2021, UK regulations require SCA for most online card payments. This means two-factor authentication for card transactions.
Stripe, GoCardless, and Checkout.com all handle SCA natively. If you’re using an older or custom payment integration, SCA compliance is likely broken — which means declined payments, lost revenue, and regulatory risk.
UK Direct Debit vs Card Payments
For subscription businesses, the choice between direct debit and card payments significantly affects revenue:
| Metric | Card Payments | Direct Debit |
|---|---|---|
| Monthly failure rate | 5–8% | 0.5–1% |
| Processing time | Instant | 3 working days |
| Chargeback risk | High | Low |
| Best for | One-time, low-subscription | Recurring, high-value |
Many successful UK SaaS companies use Stripe for card payments plus GoCardless for UK direct debit, offering both options at checkout.
Frequently Asked Questions
Do I need to register for UK VAT to sell online? You must register for UK VAT once your taxable turnover exceeds £90,000 (2026 threshold). For digital services sold to UK consumers from outside the UK, different rules apply. Stripe Tax handles calculation and collection once you’re registered.
Which payment gateway is best for a UK SaaS startup? Stripe. Lower fees than US rates, full SCA compliance, Stripe Billing for subscriptions, and Stripe Tax for VAT. Start with Stripe and add GoCardless direct debit when you have enough UK subscribers to justify it.
Can I use Stripe if my business is registered in the UK? Yes. Stripe supports UK-registered businesses fully. Payouts go to your UK bank account in GBP.
What’s the cheapest UK payment gateway? GoCardless at 1% + 20p (capped at £4) is cheapest for direct debit. Stripe at 1.5% + 20p is competitive for card payments. For in-person, Square at 1.75% is hard to beat.
Do UK payment gateways support USD pricing? Yes. Stripe supports multi-currency pricing natively. You can show prices in USD, EUR, GBP, and auto-convert. Stripe settles to your GBP account at the mid-market exchange rate.
