How to Pay an Overseas Supplier from the UK: Fastest and Cheapest Options

Paying a supplier overseas should be routine, yet many UK businesses lose money on every transfer without noticing. The fastest and cheapest route for most firms is a specialist FX provider or a multi-currency account, not a high street bank wire. Banks often build a margin into the exchange rate and add transfer fees on top, so the true cost can be well above the headline fee.

## The short answer Paying a supplier overseas should be routine, yet many UK businesses lose money on every transfer without noticing. The fastest and cheapest route for most firms is a specialist FX provider or a multi-currency account, not a high street bank wire.

This guide compares the main ways to pay an overseas supplier from the UK, shows where the hidden costs sit, and gives you a simple process to follow on your next payment.

The short answer

• Fastest: a local-currency payment from a multi-currency account, or an FX provider that pays out through local rails. Same-day or next-day settlement is common for major currencies, but timing depends on the currency, cut-off times and compliance checks.
• Cheapest: the lowest total cost, meaning the exchange rate plus all fees. Compare the amount your supplier actually receives, not the fee shown.
• Best for repeat payments: a dedicated account manager, forward contracts to fix the rate, and bulk payments for several suppliers at once.

Four ways to pay an overseas supplier from the UK

There is no single best method. The right choice depends on how often you pay, how much, and in which currency. Speed and cost vary by provider and currency, so treat this as a general guide and always get a quote.

1. Bank SWIFT transfer

Typical speed: 1 to 5 working days. Cost: a transfer fee plus a margin in the exchange rate, and intermediary bank charges are possible. Best for one-off payments if you want to stay with your bank. It is familiar and widely accepted, but the exchange rate often includes a margin, and a payment can pass through intermediary banks that each take a fee. That makes the final amount harder to predict.

2. Specialist FX provider

Typical speed: often same day to 2 working days. Cost: usually a tighter exchange-rate margin and fewer fees, so ask for the all-in rate. Best for regular or larger supplier payments. Providers focused on currency can offer sharper rates, clearer pricing and a named contact. A regulated provider will also complete identity and source-of-funds checks before the first payment.

3. Multi-currency account

Typical speed: fast when paying from a balance you already hold. Cost: avoids repeated conversions and can pay in local currency. Best for businesses that pay and receive in the same currency. Holding balances in the currencies you use lets you pay suppliers without converting each time, and you can receive customer payments in the same currency. Read more about currency accounts.

4. Card or online wallet

Typical speed: instant to a few days. Cost: often higher percentage fees and weaker rates on larger amounts. Best for small, urgent or sample orders. Convenient, but rarely the cheapest for repeat or high-value supplier payments.

What an overseas payment really costs

The biggest cost is usually not the transfer fee. It is the gap between the mid-market exchange rate and the rate you are given. Three costs can apply to a single payment:

• Exchange-rate margin: the markup on the mid-market rate. It is built into the rate, so it rarely appears as a line item.
• Transfer fee: a flat or percentage charge for sending the payment.
• Intermediary and receiving-bank fees: charges taken along the SWIFT route, which can reduce what your supplier receives.

An illustrative example. Suppose you pay a supplier the equivalent of £10,000 in euros, and the mid-market rate is 1.15. The figures below are illustrative only, not a quote or a real rate.

• Mid-market rate (benchmark), 0% margin: €11,500.00
• Provider with a tight margin, 0.5%: €11,442.50
• Provider with a wide margin, 3%: €11,155.00

In this example the gap between the two margins is €287.50 on one payment. Paid monthly, that adds up quickly. The takeaway: always ask for the all-in rate and the exact amount the supplier will receive, then compare quotes on that number.

How to pay an overseas supplier: step by step

1. Confirm the invoice details. Check the amount, currency, due date and who bears the fees. Ask whether the supplier prefers payment in their local currency or yours.
2. Verify the bank details. Get the IBAN or account number and the SWIFT/BIC code in writing, then confirm them by phone using a number you already trust. This protects you against invoice and payment fraud.
3. Get quotes. Ask each provider for the all-in rate and the exact amount the supplier will receive. Compare on that figure.
4. Choose your timing. If the due date is weeks away and the rate matters, consider a forward contract to fix today's rate for a future payment.
5. Complete onboarding checks. A regulated provider will ask for company and director identity documents and, for larger payments, the source of funds. Doing this before you need to pay avoids delays.
6. Send the payment and keep the confirmation. Share the payment reference or proof of payment with your supplier so they can match it quickly.
7. Reconcile. Record the rate and fees against the invoice for your accounts, and review them against your next quote.

Six ways to cut cost and speed things up

• Pay in the supplier's currency where you can. Avoiding an extra conversion on their side can reduce friction, and it makes your cost easier to forecast.
• Send before cut-off times. Payments made late in the day or near weekends and bank holidays in either country may settle a day or more later.
• Batch supplier payments. If you pay several suppliers, mass payments can save admin time and repeated effort.
• Hold balances in your main currencies. If you also sell overseas, a multi-currency account lets you reuse incoming funds to pay suppliers.
• Fix the rate on large or regular payments. Forward contracts and limit orders give you certainty on cost, which helps with pricing and margins.
• Get set up before the first invoice is due. Account opening and compliance checks are the most common cause of avoidable delay.

Frequently asked questions

What is the cheapest way to pay an overseas supplier from the UK?

The cheapest option is the one with the lowest total cost: exchange rate plus all fees. For regular or larger payments, a specialist FX provider or multi-currency account is often cheaper than a bank transfer. Compare quotes on the amount your supplier receives.

How long does an international supplier payment take?

It varies by currency, route and provider. Major-currency payments can arrive the same day or within a few working days, while payments through multiple intermediary banks can take longer. Compliance checks and cut-off times also affect timing.

Do I pay fees to receive money from overseas, and does the supplier?

Possibly. Intermediary and receiving banks can deduct fees on SWIFT payments, so your supplier may receive less than you sent. Ask your provider how fees are shared and whether you can cover them so the supplier receives the full invoice amount.

Can I lock in an exchange rate for a future supplier invoice?

Yes. A forward contract lets you agree a rate today for a payment on a future date, which helps with budgeting and margin protection.

Is it safe to use a specialist provider instead of my bank?

Check that the provider is authorised by the FCA, and read their regulatory and safeguarding information before you transfer funds.
