How to Send Money Internationally: A UK Business Guide (2026)

For a UK business, "send money internationally" usually means paying an overseas supplier, a foreign contractor, a subsidiary, or a marketplace fee — not a personal remittance. The mechanics resemble a domestic transfer, but currency conversion, intermediary banks, and compliance add cost and delay. This guide covers the main ways UK businesses send money abroad, walks through the steps, shows where the hidden cost sits, and points to a global pay-out option for regular cross-market payments.

The main ways to send money internationally

Bank SWIFT wire

Your bank sends instructions over the SWIFT network; funds may pass through intermediary banks. Typically 3–6 business days. Cost is usually a flat fee (often ~$20–50) plus a 1–3% FX markup above mid-market. Secure and relationship-backed, but weak on transparency and speed. Best for large, infrequent transfers.

Multi-currency / payment-institution account

Provides local bank details in multiple currencies so you can pay and get paid like a local, settling via local rails instead of SWIFT (often same-day). Best for businesses transacting in several currencies regularly — it removes forced conversions.

Online money transfer services

Digital platforms with upfront rates and fees (commonly ~0.4–1.5% of the amount), arriving in 1–2 days. Transparent and simple, but may cap business volume or restrict some countries.

Business cards

For online supplier, ad, and SaaS spend, a virtual business card with set limits spends in the local currency directly — no wire needed for many recurring payments; a physical card covers in-store or wallet-bound spend.

These are categories, not a provider scorecard; the cost figures are typical industry ranges — verify each provider's live pricing. Most businesses use more than one method depending on the payment.

Step-by-step: sending money abroad as a UK business

Pick the method by amount, currency, and frequency (see categories above).
Gather payee details — for international: beneficiary name, IBAN, SWIFT/BIC; for UK: account number and sort code. A transposed digit bounces a payment back days later.
Prepare source-of-funds documents if the amount is large or the payee is new (invoices, contracts).
Check the all-in cost — exchange rate plus fees plus any intermediary deductions.
Authorise — large amounts often need 2FA or biometrics and may trigger a compliance review.
Track to confirmation, and confirm receipt with the payee through an independent channel.

The real cost — and how to avoid hidden FX charges

The flat fee is the small, visible number; the FX markup is the killer. A 1–3% markup on a meaningful transfer dwarfs any wire fee. Save by:

Comparing the all-in cost, not the headline fee.
Using the mid-market rate where possible.
Settling via local rails that bypass intermediary banks.
For regular multi-currency payments, using a multi-currency account that removes forced conversions entirely.

How long does it take?

SWIFT wire: 3–6 business days.
Online transfer service: 1–2 days.
Local-rail / multi-currency: often same-day.

Let urgency drive the method, not the other way around — and build in lead time for a possible compliance review on large or first-time payments.

Staying safe

Verify new payee details through an independent channel — invoice-redirect fraud is common on business payments.
Double-check account details character by character.
Beware deadline pressure — scammers manufacture urgency.
Never rush a large payment; authorise with enough lead time to absorb a check.

Choosing a method for your business

Regular multi-currency payments → a multi-currency / payment-institution account (local rails, no forced FX).
One-off large transfer → weigh a bank wire or a pay-out provider on cost vs speed.
Recurring ad / SaaS / supplier spend → virtual business cards with per-transaction limits.

A global pay-out option for UK businesses: PhotonPay

For UK businesses that pay suppliers, contractors, and subsidiaries across markets, the question isn't just "how do I send this" but "how do I do it repeatedly, cheaply, and safely." PhotonPay is built as a global pay-in/pay-out solution rather than a UK high-street account.

What that means in practice for international payments:

Pay out globally. Global payout reaches 200+ countries/regions in 60+ currencies, as fast as 1 business day, with smart routing that avoids intermediary banks and their fees. FX is at transparent interbank rates with no hidden fees.
Spend with PhotonPay business cards. Issued on the Mastercard + Discover® Global Network in both virtual and physical form, they let you set per-transaction, daily, and monthly limits and freeze cards instantly. Use a virtual card for online ad, SaaS, and subscription spend, and a physical card for in-store payments or to bind it to Google Pay or Apple Pay.
Settle with stablecoins as an optimisation layer. You can fund your PhotonPay account with stablecoins (USDC or USDT); stablecoins act as a settlement layer and the PhotonPay Card makes the actual merchant payment.

PhotonPay is positioned as a next-generation Payment Operating System serving 200,000+ businesses across 200+ countries/regions, FCA-authorised in the UK, with a UK office and global local presence. It complements a UK business account where international pay-out is the priority.

Frequently Asked Questions

What's the cheapest way to send money internationally for a business?

Usually a multi-currency or payment-institution account settling via local rails, or an online transfer service for mid-sized amounts — both avoid SWIFT intermediary fees and tight FX markups. Always compare the all-in cost, not the headline fee.

How long does an international transfer take?

SWIFT: 3–6 business days. Online services: 1–2 days. Local-rail / multi-currency: often same-day. Speed depends on the method and any compliance review.

What details do I need to send money abroad?

Beneficiary name, IBAN, SWIFT/BIC, amount, currency, and reason. For UK domestic, the account number and sort code. Accuracy matters more on large sums because a bounce is costlier and slower.

Why is my transfer more expensive than the fee suggests?

The FX markup (commonly 1–3% above mid-market) usually exceeds the flat fee. Check the all-in cost — rate plus fees plus any intermediary deductions.

Bank vs payment institution for international payments?

A bank offers relationships and FSCS on eligible deposits but higher FX and SWIFT routing; a payment institution offers safeguarded funds, often better FX, and local rails, with no FSCS backstop. Weigh protection against cost and reach.
