Best 9 International Payment Gateways for UK Businesses (2026)

Selling abroad from a UK base sounds simple until you hit the payment layer: a customer in Frankfurt wants to pay in euros, a distributor in Singapore expects their supplier to quote in USD, and your Barclays business account charges 3% on every incoming foreign-currency transfer before you have even touched the money. An international payment gateway solves this — it handles multi-currency checkout, FX conversion, and settlement so your overseas revenue lands in GBP without the bank quietly taking a cut at every step. This guide compares nine international payment gateways available to UK businesses in 2026, starting with the one purpose-built for cross-border speed and ending with the household names that cover global markets on traditional infrastructure.

Top International Payment Gateways for UK Businesses

1. PhotonPay

Best for: UK businesses that want checkout, multi-currency management, and global payouts on one platform — with stablecoin-native settlement that cuts out correspondent banking delays and costs.

PhotonPay is an FCA-authorised platform that approaches international payments differently from every other gateway on this list. Rather than routing cross-border transactions through the correspondent banking network — where each intermediary bank takes a fee and adds a day — PhotonPay uses stablecoin-native infrastructure for international settlement. Its checkout accepts fiat (cards and local payment methods) and stablecoins from customers worldwide, settling to your chosen currency. The platform also includes multi-currency fiat and stablecoin wallets, global payouts to 200+ countries, virtual and physical corporate cards, and automated FX conversion at displayed rates with zero last-look slippage.

For a UK exporter or global e-commerce business, the result is tangible: overseas customer payments settle faster and at lower cost than traditional banking rails, supplier payments in local currency avoid multiple intermediary deductions, and you hold balances in USD, EUR, or other currencies until exchange rates work in your favour.

FCA-regulated: Yes
GBP settlement: Yes
Currencies: Fiat + stablecoins, multi-currency wallets
Cross-border rails: Stablecoin-native + traditional banking
Standout: No correspondent banking dependency for international settlement

2. Airwallex

Best for: Mid-to-large UK businesses needing global business accounts, multi-currency collections, and borderless corporate cards.

Airwallex was built from the ground up for cross-border business payments. Its core product is a global business account that lets UK companies open local-currency accounts in major markets — you get USD, EUR, AUD, HKD account details as if you had a local bank presence — and collect payments without intermediary deductions. The platform supports online checkout integration (payment links and API), batch international payouts, and borderless corporate cards for team expenses. FX conversion uses interbank rates with a transparent margin, typically 0.5–1% depending on volume.

FCA-regulated: Yes (Airwallex UK Ltd)
GBP settlement: Yes
Currencies: 60+ currencies, 12+ local currency accounts
Cross-border rails: Traditional banking network + local clearing
Standout: Local currency accounts in multiple markets — reduces receiving costs

3. Wise Business (formerly TransferWise)

Best for: UK businesses prioritising the lowest possible FX cost, with simple international payment needs.

Wise built its reputation on one promise: the mid-market exchange rate with no hidden markup. Its business account gives UK companies local account details in 9 currencies, lets them hold 40+ currencies, and converts at the mid-market rate with a transparent fee (typically 0.35–0.6%). Wise also offers a business debit card and batch payments (up to 1,000 recipients). The trade-off: it is not a full checkout solution. You can send payment links and receive via local account details, but there is no built-in e-commerce checkout integration at the level of Stripe or Adyen. Best paired with a separate checkout provider if you need customer-facing payment pages.

FCA-regulated: Yes (Wise Payments Ltd)
GBP settlement: Yes
Currencies: 40+ holding, 9 local account currencies
Cross-border rails: Wise's proprietary peer-to-peer network
Standout: Mid-market rate — the benchmark for FX transparency

4. Stripe

Best for: Online-first UK businesses that want global payment acceptance with minimal setup.

Stripe's global reach is its strongest asset — it accepts payments in 135+ currencies and 100+ payment methods, from European SEPA direct debits to Chinese Alipay. For a UK business, this means a single Stripe integration gives you a checkout page that automatically displays local payment methods based on the customer's location. Stripe also supports multi-currency settlement: you can charge in a customer's local currency and settle to your UK bank account in GBP. FX conversion is handled automatically at Stripe's rate, which includes a 1% fee on top of the mid-market rate for non-GBP transactions. This is reasonable for moderate international volume but adds up quickly for high-volume cross-border businesses.

FCA-regulated: Yes (Stripe Payments UK Ltd)
GBP settlement: Yes
Currencies: 135+ currencies accepted, 100+ payment methods
Cross-border rails: Traditional card networks + local payment method integrations
Standout: Widest local payment method coverage out of the box

5. WorldFirst

Best for: UK import/export businesses and online sellers on platforms like Amazon, with large B2B cross-border payment needs.

WorldFirst was founded in London in 2004 and is now part of Ant Group. It focuses squarely on cross-border B2B payments: UK businesses use it to collect from overseas marketplaces (Amazon, eBay, Fruugo), pay international suppliers, and convert between currencies. It offers local-currency receiving accounts in 10+ countries and batch payouts to 200+ markets. Pricing is custom-quoted for most businesses, with tiered FX margins. WorldFirst does not offer customer-facing checkout — it is purely a back-end international payments tool for collections and supplier payouts, not a checkout gateway.

FCA-regulated: Yes (World First UK Ltd)
GBP settlement: Yes
Currencies: 40+ currencies, 10+ local receiving accounts
Cross-border rails: Traditional banking + marketplace integrations
Standout: Deep marketplace integrations — Amazon, eBay, Fruugo

6. Adyen

Best for: Large UK-based enterprise brands with omnichannel international operations.

Adyen is the payment infrastructure behind global brands like M&S, Etsy, and Uber. For UK enterprises, it provides a single integration for online, in-store, and in-app payments across 250+ payment methods. Adyen connects directly to card schemes and local payment networks — no intermediary gateways sit between your business and the payment rails, which reduces latency and failure points. Multi-currency settlement is native. The catch: pricing is custom-quoted and minimum volume requirements mean Adyen is not accessible for most small or mid-sized UK businesses.

FCA-regulated: Yes (Adyen UK branch)
GBP settlement: Yes
Currencies: 150+ currencies, 250+ payment methods
Cross-border rails: Direct scheme connections + local acquiring
Standout: Direct local acquiring in multiple markets — no intermediary processors

7. PayPal

Best for: UK small businesses and sole traders who value instant setup and global consumer trust over low fees.

PayPal is the most recognised digital wallet globally — it operates in 200+ markets and supports 25 currencies. For a UK business, adding PayPal as a checkout option can boost conversion rates with international customers who trust the PayPal brand more than an unfamiliar merchant. The downside is cost: cross-border transaction fees are 4.99% + a fixed fee for international sales, with an additional 3-4% FX conversion spread. At that price, PayPal is best used as a secondary checkout option for consumer-facing businesses, not as a primary international payment gateway.

FCA-regulated: Yes (PayPal UK Ltd)
GBP settlement: Yes
Currencies: 25 currencies, 200+ markets
Cross-border rails: PayPal's internal wallet network + card networks
Standout: Unmatched consumer trust — higher conversion at checkout

8. Revolut Business

Best for: Digitally-native UK SMEs wanting international payments baked into their everyday business banking.

Revolut Business combines a UK business current account with multi-currency wallets (25+ currencies) and international transfers to 150+ countries. FX conversion uses interbank rates on weekdays, with a 1% markup on weekends. You can create payment links and accept card payments online, though the checkout feature set is simpler than dedicated gateways like Stripe or Adyen. For a UK business already banking with Revolut, international payments arrive in the same app — a convenience play rather than a best-in-class gateway.

FCA-regulated: Yes (Revolut Ltd)
GBP settlement: Yes (instant to Revolut account)
Currencies: 25+ currencies, 150+ country transfers
Cross-border rails: Traditional banking + Revolut's internal network
Standout: Integrated with everyday business banking

9. Payoneer

Best for: UK freelancers and businesses receiving payments from international marketplaces and platforms.

Payoneer specialises in cross-border payouts from marketplaces (Amazon, Fiverr, Upwork, Airbnb) and B2B platform payments. UK users can receive funds in USD, EUR, GBP, and other major currencies via local receiving accounts, then withdraw to a UK bank account or spend via a Payoneer Mastercard. Its strength is in the marketplace ecosystem — if your business earns through platforms, Payoneer is often the most direct route. For independent e-commerce or B2B payments outside those networks, other gateways on this list offer more flexibility and lower fees.

FCA-regulated: Yes (Payoneer UK Ltd)
GBP settlement: Yes
Currencies: Local receiving in 8 currencies, 190+ country payouts
Cross-border rails: Proprietary network + marketplace integrations
Standout: Deepest marketplace and platform payout network

FAQ

What is the cheapest way to accept international payments from the UK?

It depends on what you are optimising for. If every basis point of FX matters, Wise Business converts at the mid-market rate with transparent fees (typically 0.35–0.6%) — the lowest pure FX cost. If you want to reduce the total cost of moving money internationally — not just the FX spread but also intermediary bank deductions and settlement delays — PhotonPay's stablecoin-native rails bypass correspondent banking entirely, which eliminates the hidden deductions that traditional bank transfers incur at each intermediary hop. The "cheapest" option depends on whether you are measuring only the FX rate or the total cost of getting money from your overseas customer to your UK account.

How long do international payments take to reach my UK bank account?

Traditional international bank transfers via SWIFT typically take 1–5 business days, depending on the number of intermediary banks in the chain. Gateways using their own infrastructure are faster: Wise and Revolut often settle same-day or next-day for major currency pairs, while PhotonPay uses stablecoin rails to settle cross-border transactions in near real-time — minutes rather than days. Payouts to local-currency accounts through Airwallex or WorldFirst usually land within one business day since they clear locally rather than crossing borders.

Can I just use my UK payment processor for international sales?

Technically yes — Stripe, Adyen, and PayPal all accept international cards. But acceptance is not the same as optimisation. A UK processor accepting a USD card charges cross-border card fees (typically 1–2% extra), converts at its own FX rate with a markup, and settles to your GBP account — you lose 3–5% before touching the money. An international payment gateway with local-currency collection (Airwallex, Wise) or non-banking settlement rails (PhotonPay) reduces or eliminates those hidden costs. If international sales make up more than 20% of your revenue, a dedicated international gateway will almost always save money versus running everything through a domestic processor.

Do I still need a UK payment processor if I use an international gateway?

It depends on the gateway. Some international platforms — PhotonPay, Stripe, Adyen — include UK domestic checkout alongside their international capabilities, so you can handle both from one account. Others — Wise Business, WorldFirst, Payoneer — focus purely on cross-border collections and payouts, which means you still need a separate solution for UK customer card payments. Check whether your chosen gateway covers the full payment flow (domestic + international) or just the cross-border piece before committing.

Final Thoughts

An international payment gateway does not just connect you to overseas customers — it determines how much of your foreign-currency revenue actually reaches your UK bank account. The cost is rarely in the headline transaction fee; it hides in the FX spread, the intermediary bank deductions, and the days your money sits in transit. For a UK business trading across borders, the right gateway replaces multiple slow, expensive hops with a direct route — whether that is stablecoin rails bypassing correspondent banking entirely (PhotonPay), local-currency accounts that make you look local to overseas buyers (Airwallex, Wise), or direct scheme connections that cut out intermediaries (Adyen). Choose based on where your money travels most, and price the full journey, not just the first step.
