Moving a large sum overseas — for a property purchase, business acquisition, inheritance, or supplier payment — is one of those moments where tiny pricing differences and small admin mistakes can turn into big costs or delays. The good news: there is a “best way” for most high-value transfers — and it usually isn’t your high-street bank. In most cases, the best option is a specialist currency broker using bank-grade payment rails, with clear pricing, proper compliance support, and tools to manage rate risk.
Quick Answer
For £25,000+ (and especially £100,000+), the best all-round approach is: a specialist currency broker for the conversion and rate strategy, working with FCA-authorised payment partners for processing, and a named account manager to avoid expensive errors. See why banks give worse exchange rates to understand what you’re currently paying.

What Counts as a “Large” International Transfer?
- £10,000+: typically triggers source of funds checks. See documents needed for large transfers.
- £50,000–£250,000: where rate quality and specialist guidance start to matter a lot. See what international transfers actually cost.
- £250,000–£1,000,000+: where timing, documentation, and risk management become central
On £100,000, a 1% pricing difference means £1,000 more or less received. Use our exchange rate comparison tool to see how we compare to your bank.
Why Specialist Brokers Often Win for Large Transfers
1. Pricing usually improves at larger amounts
Banks bundle costs into the exchange rate. With a specialist broker, you’re typically looking at tighter pricing, especially on six-figure transfers. The rate difference is often 2–3% at a bank versus 0.3–0.8% at a specialist.
2. You get tools to manage rate risk
If you have a completion date in 4–12 weeks, you can reduce uncertainty using: a forward contract to lock a rate for a future date, a limit order to target a better rate automatically, or staged transfers to split timing risk. See our forward contracts guide and our guide on timing your exchange.
3. Fewer avoidable delays
High-value transfers often slow down due to missing paperwork, beneficiary detail errors, or payment screening questions. Having your documentation ready and using a broker-led process avoids most delays. If a payment is delayed, an MT103 lets you trace it through the SWIFT chain.

The Best Way to Transfer a Large Amount: Step-by-Step
Step 1: Get a quote and confirm the true total cost
Ask for the exchange rate you’ll receive, any transfer fees, and the net amount the recipient will receive. Compare against the mid-market rate to understand the all-in margin. Use our exchange rate comparison tool or live currency converter.
Step 2: Prepare documents early
For large transfers, you’ll typically need proof of ID, proof of address, and proof of source of funds. See the full documents checklist for large transfers.
Step 3: Choose your timing plan
Fixed deadline? Consider locking a rate with a forward contract. Flexible? Consider a limit order or set a rate alert. See our guide on whether now is a good time to exchange.
Step 4: Confirm beneficiary details carefully
Double-check account name, IBAN/account number, SWIFT/BIC, bank name and address, and the purpose/reference. Errors cause the most common delays.
Step 5: Book, send, and track
Once booked, funds are sent on the agreed rails. See our guide on how long international transfers take. Use an MT103 if any payment is delayed.

FAQs
Does the UK limit how much money you can send abroad?
No single cap, but large transfers are subject to standard AML checks. See our guide on how much you can send abroad from the UK.
What’s the cheapest way to transfer £100,000+ internationally?
A specialist broker — because the exchange rate margin is the main cost driver, not the visible transfer fee. Use our rate comparison tool to see the difference.
Should I lock a rate for a property completion?
Yes, if you have a fixed deadline. A forward contract removes rate uncertainty between exchange of contracts and completion.
