Transferring money abroad from the UK costs more than most people realise. UK banks charge 2–4% above the interbank rate on every conversion — on top of any transfer fee. On a £50,000 transfer that’s up to £2,000 in hidden costs. A currency specialist working with FCA-authorised partners typically charges 0.3–0.8%, saving thousands on larger transfers.
The Two Costs Nobody Tells You About
Every international transfer has two costs: the transfer fee (the amount shown upfront) and the exchange rate margin (the hidden markup applied to the rate). Banks are transparent about the first and quiet about the second — which is where most of the money is lost.
The interbank rate is the rate banks use when trading with each other. When you transfer money abroad, your bank quotes you a rate that’s worse than this — the difference is their margin. On a £100,000 transfer, a 3% margin costs £3,000. On a £300,000 property purchase, it’s £9,000. This is one of the core reasons banks consistently give worse exchange rates than currency specialists.

Why Banks Charge So Much
International transfers are not a core banking product — they’re a side service. Banks route payments through the SWIFT network, often passing through one or more correspondent banks, each of which can deduct their own fee. The sending bank adds a currency conversion margin on top. The result is a chain of costs, many invisible until the money arrives short at the other end. This is particularly common for transfers to the UAE, USA, Australia, or India.
SEPA vs SWIFT: Does the Route Change the Cost?
Yes — significantly. SEPA transfers (euro payments within the EEA) are typically free or very low cost at most UK banks. SWIFT — used for non-euro payments or transfers outside the EEA — is slower, can attract correspondent bank fees, and carries the full exchange rate margin. Sending euros to France, Spain, or Germany? SEPA is cheaper. Sending dollars, dirhams, or rupees? A specialist broker will almost always outperform a bank on rate.
What This Means for Property Buyers
Property transfers are where the cost gap is most stark. A bank completing a £250,000 purchase at a 3% margin costs £7,500 in hidden FX charges. A currency specialist at 0.5% costs £1,250. The difference — £6,250 — is real money that doesn’t need to leave your pocket. Beyond the margin, a forward contract lets you fix the rate weeks or months in advance. See our full guide to buying property abroad for more on managing currency risk during a purchase.
What This Means for Businesses
For businesses making regular international payments — importing goods, paying overseas suppliers, repatriating earnings — the margin compounds. Twenty transfers a month at 3% on £10,000 each adds £72,000 in unnecessary costs per year.

How to Get a Better Rate
- Use a currency specialist working with FCA-authorised partners for any transfer over £5,000
- Compare the rate, not just the fee — a £0 fee at 3% costs more than a £10 fee at 0.5%
- Ask for the interbank rate and compare it to what you’re quoted
- Consider a forward contract if you have a known transfer in the next 1–12 months
- Never transfer in-branch — bank branch rates are typically worse than online
- Batch transfers where possible — one larger transfer usually gets a better rate
What to Look for in a Currency Specialist
- FCA-authorised partners — ensure your specialist works exclusively with FCA-regulated payment providers, keeping your funds fully protected at every stage
- Client fund safeguarding — your money should be held in segregated client accounts, never mixed with company funds. Read more about how client funds are safeguarded
- A real person to speak to — for large transfers, you want a specialist, not a platform
- Transparent pricing — a reputable broker tells you the exact rate and margin upfront
