Best Way to Exchange Large Amounts of Currency
Specialist FX broker for UK clients transferring £25,000 to £5 million and above — for property abroad, inheritance, business sales, investments and family transfers. Stronger rates than UK high-street banks, no transfer fees, and a dedicated dealer who handles your transaction by phone from quote to settlement.
The best way to exchange large amounts of currency is through an FCA-authorised specialist currency broker, not a high-street bank. On a transfer of £500,000, a typical UK bank will charge 2–4% in built-in FX margin (£10,000–£20,000) plus fees. A specialist broker charges 0.15–0.5% on equivalent transfers, with no transfer fees over £5,000. The larger the transfer, the wider the gap. Cambridge Currencies handles UK large currency transfers in over 30 currencies through Currencycloud and ScioPay (both FCA-authorised), with every transaction completed by phone with a dedicated dealer.
Live mid-market rate from Frankfurter. Indicative tiered pricing — your actual quote is confirmed live by phone before any transfer is booked.
Exchange Rate History
When do people transfer large sums of money internationally?
Most large currency transfers cluster around five life and business events. The right approach — spot, forward contract or limit order — depends on which event you’re solving for and the timing involved.
Buying property abroad
UK buyers funding villas in Spain, farmhouses in Tuscany, second homes in Portugal or Florida, or chalets in the Alps. Typical lump sums £200,000–£1.5m. Forward contracts protect the GBP cost between offer accepted and completion.
Selling overseas property
Repatriating sale proceeds in EUR, USD, AUD or other currencies back to a UK account. Often six- or seven-figure single transfers, where every basis point of FX margin lands on the bottom line.
Inheritance and estate transfers
UK beneficiaries receiving inheritance from overseas estates, often in EUR or USD. Funds typically held in notary or executor accounts before release; specialist handling around documentation accelerates the process.
Investments and capital movements
International portfolio rebalancing, foreign property investment funding, capital injections into overseas subsidiaries, dividend repatriation. Where institutional rates and forward cover both matter.
Business sales and acquisitions
Cross-border M&A consideration, founder exit proceeds from foreign-domiciled companies, earn-out settlements. Often the single largest currency conversion of a founder’s career.
Family and emigration transfers
Funding emigration plans, transferring savings to retirement destinations, gifting capital to children abroad. Long-term horizons that benefit from rate-fixing tools rather than ad-hoc transfers.
How rates compare on large transfers: bank vs app vs specialist broker
For smaller payments under £5,000, money apps like Wise are usually fastest and cheapest. The picture changes sharply once the transfer size enters the £25,000+ territory. UK high-street banks routinely apply wider FX margins on larger transfers (not narrower), while specialist brokers do the reverse — the bigger the transfer, the better the rate.
| Feature | UK high-street bank | Money app | Specialist broker |
|---|---|---|---|
| FX margin (£25k+) | Poor (2–4%) | Fair (0.4–0.7%) | Strong (0.25–0.5%) |
| FX margin (£100k+) | Poor (2–4%) | Fair (0.4–0.7%) | Premium (0.15–0.25%) |
| Transfer fees | £15–£40 per payment | Variable, climbs over £20k | None over £5,000 |
| Forward contracts | Private banking only | Limited or none | Yes, up to 12 months |
| Limit & market orders | Not typical | Not available | Yes |
| Multi-currency | Major pairs only | 40+ currencies | 30+ currencies including emerging markets |
| Dedicated specialist | Branch staff | In-app support | One named dealer, by phone |
| Speed (major currencies) | 2–5 working days | Same day–48 hours | 1–2 working days |
| Best for | Convenience, small amounts | Single payments under £20k | Transfers over £25,000 |
How much can you save on a large currency transfer?
The maths is straightforward: FX margin scales with transfer size. The same percentage of margin produces a much larger absolute cost on a £1m transfer than on a £25k one — which is why the saving from using a specialist over a bank grows in line with the trade size.
The table below uses an illustrative interbank GBP/EUR rate of 1.165. Live rates differ — savings figures scale proportionally.
| Transfer size | Bank cost (3% margin) | Money app (0.6%) | Specialist broker |
|---|---|---|---|
| £25,000 | £750 | £150 | £125 (0.5%) |
| £100,000 | £3,000 | £600 | £250 (0.25%) |
| £250,000 | £7,500 | £1,500 | £500 (0.20%) |
| £500,000 | £15,000 | £3,000 | £750 (0.15%) |
| £1,000,000 | £30,000 | £6,000 | £1,500 (0.15%) |
| £2,500,000 | £75,000 | £15,000 | £3,750 (0.15%) |
Worked example: £500,000 Spanish property purchase
A UK buyer completing on a €500,000 villa in Marbella has been quoted GBP/EUR 1.165 mid-market. The completion is six weeks away.
Through a UK bank at a 3% margin (rate of 1.130), the buyer pays £442,478 plus a £25 wire fee — total £442,503.
Through a specialist broker at a 0.15% premium-tier margin (rate of 1.163), the buyer pays £429,923, no fee.
Currency tools for large transfers
The biggest difference between a bank and a specialist broker on large transfers isn’t just price — it’s access to the FX risk-management tools that make a known future payment predictable in GBP terms.
How a large transfer works with Cambridge Currencies
Account opening is free and most accounts are cleared within one working day. Once verified, every transfer follows the same process — with your dedicated dealer handling rate, timing and documentation throughout.
- Open a free accountRegister online or by phone — takes around 10 minutes. We need passport or driving licence, proof of UK address, and a brief outline of the transfer purpose. Most accounts are live within 1 working day.
- Confirm rate live by phoneSpeak to your named dealer with the GBP amount or the foreign-currency target. Rate quoted live against the interbank market — what’s quoted is what books. No rate changes between quote and execution.
- Choose spot or forwardFor transfers due in the next 48 hours, take spot. For transfers due in 1–12 months, consider a forward contract to lock in today’s rate. Your dealer will walk through both with realistic numbers for your situation.
- Provide source-of-funds documentationFor transfers above £100,000, expect to provide source-of-funds evidence — property completion statement, grant of probate, bank statements or business sale agreement. Your dealer flags exactly what’s needed before you send funds.
- Send GBP to the segregated client accountTransfer GBP via UK Faster Payments, BACS or CHAPS to the FCA-safeguarded client account provided. Funds typically land within hours.
- Currency delivered to the recipientWe convert and pay the foreign currency directly to the named beneficiary. Most major-currency payments arrive within 1–2 working days. You receive an MT103 confirmation as proof of payment.
Source-of-funds documentation: what to prepare
UK FCA-authorised payment institutions are required to verify source of funds on higher-value transfers. This isn’t a hurdle — it’s a regulatory standard that protects every party. Having the right documents ready accelerates onboarding and avoids settlement delays.
For property sale proceeds: the completion statement from the conveyancer or notary, plus the most recent bank statement showing the funds.
For inheritance: grant of probate or letters of administration, and the executor’s distribution statement.
For business sale proceeds: the share purchase agreement and a bank statement showing the funds received.
For accumulated savings or investments: 6–12 months of bank or investment account statements showing the build-up.
The regulatory background is published on GOV.UK and provider authorisations can be checked on the FCA Register.
Common mistakes on large currency transfers
- Defaulting to your bank without comparing. Most clients have never compared a bank rate against a specialist quote. On a six-figure transfer, that one-time comparison can be worth more than a year’s mortgage payments.
- Treating completion day as the FX moment. Property timelines give you 4–12 weeks of FX risk between offer-accepted and completion. A forward contract booked at offer-accepted removes that risk entirely — for the cost of a 5–10% deposit.
- Letting the receiving bank do the FX. Sending GBP to a foreign account and letting the recipient bank convert is the most expensive route. The receiving bank takes whatever margin it wants, and you have no visibility. Always convert at your end.
- Ignoring the SWIFT intermediary deduction. Bank wires routed via correspondent banks lose £15–£30 per payment in transit, sometimes more. Specialist brokers using local-payment networks avoid these deductions on major currencies.
- Splitting one transfer into many small ones. Some clients break a £200k transfer into ten £20k chunks thinking it’s safer. It’s actually more expensive (each transfer attracts standard-tier pricing) and often raises more compliance flags, not fewer.
- Waiting until the last minute. Onboarding plus source-of-funds verification can take 2–5 working days. Last-minute transfers force you to accept whatever rate is available and miss windows for forward booking. Engage your specialist as early as possible.
Tax considerations on large international transfers
Cambridge Currencies is not a tax adviser. The points below are general orientation only — always confirm your specific position with a qualified tax specialist before a material transfer.
Moving existing capital is generally not in itself taxable. Transferring savings, property sale proceeds or inherited funds across borders does not separately trigger UK tax simply because of the transfer. The underlying transaction may have tax consequences (capital gains on a property sale, for example), but the act of moving money internationally is not separately taxed.
The UK remittance basis was abolished in April 2025. The non-domiciled remittance basis was replaced by a residence-based foreign income and gains regime from 6 April 2025. UK residents are now generally taxed on worldwide income, with transitional relief in place. Official guidance is published on GOV.UK — Tax on foreign income.
Inheritance from overseas estates is typically not subject to UK inheritance tax in the beneficiary’s hands — UK IHT is paid by the estate, not the recipient. However, if the estate is UK-domiciled, IHT may apply at estate level. Foreign jurisdictions may have their own succession taxes.
Reporting: for UK residents, large international receipts are reported on self-assessment if there is a UK tax consequence. Banks and brokers separately make regulatory reports under anti-money-laundering rules — this isn’t a tax report, but it is a record.

Frequently asked questions about large international transfers
What is the best way to exchange large amounts of currency?
The best way to exchange large amounts of currency is through an FCA-authorised specialist currency broker rather than a high-street bank. Specialist brokers typically offer FX margins of 0.15–0.5% on transfers above £100,000, compared with 2–4% at UK banks. On a £500,000 transfer, that’s the difference between £750 and £15,000 of margin cost — recovered straight to your bottom line.
How much money can I transfer internationally?
There is no fixed cap on international transfers from the UK. Cambridge Currencies regularly handles transfers from £25,000 to £5 million and above. UK banks may impose their own daily limits — your specialist will help structure the transfer to work around these. For amounts above £100,000, enhanced source-of-funds documentation is typically required as part of FCA anti-money-laundering compliance.
Is it safe to transfer large sums of money internationally?
Yes — when using an FCA-authorised provider. Cambridge Currencies operates through Currencycloud (FRN 900199) and ScioPay (FRN 927951), both authorised by the UK Financial Conduct Authority. All client funds are held in segregated safeguarded accounts that are legally separate from the firm’s own money. You can verify any provider on the FCA Register at register.fca.org.uk.
How long does a large international transfer take?
Most large transfers in major currencies (USD, EUR, AUD, CAD, CHF, JPY) arrive in the recipient account within 1–2 working days from funding. Emerging-market currencies and complex SWIFT routing can take 2–5 working days. Forward contracts can be booked weeks or months ahead, with settlement on a future fixed date.
Can I lock in an exchange rate for a large transfer in advance?
Yes. A forward contract fixes today’s exchange rate for delivery up to 12 months ahead. You pay a 5–10% deposit at booking and the balance on the value date. Forward contracts are particularly valuable for property purchases (locking the rate between offer accepted and completion) and business contracts where the GBP value of foreign currency receipts or payments needs certainty.
Do banks charge more for large international transfers?
Counterintuitively, yes — UK high-street banks typically apply wider FX margins on larger transfers, often 2–4% versus the interbank rate. Specialist currency brokers do the opposite: margins narrow as the transfer size increases, falling to 0.15–0.25% on transfers over £100,000. On a £1 million transfer, that’s a £25,000+ difference between bank and broker.
What documents are required for large money transfers?
For transfers above £100,000, expect to provide proof of identity (passport or driving licence), proof of address (utility bill, bank statement), and proof of source of funds. Source-of-funds documents typically include property sale completion statements, inheritance documentation (grant of probate), business sale agreements, or savings/investment account statements. Your specialist will guide you through the exact requirements before any transfer.
What is a forward contract and when should I use one?
A forward contract is an agreement to buy currency at today’s exchange rate for delivery on a future date up to 12 months ahead. It removes exchange rate risk between today and the value date. Use one when you have a known future payment in foreign currency — an overseas property completion, a contract milestone, or a planned business payment — and you want certainty over the GBP cost or the foreign-currency receipt.
Will I pay UK tax on a large international transfer?
Transferring existing capital — savings, property sale proceeds, inheritance — across borders is not in itself taxable. The underlying transaction may have tax consequences (capital gains on a property sale, for example), but moving money internationally doesn’t separately trigger UK tax. From 6 April 2025, UK residents are taxed on worldwide income under the residence-based regime. Always confirm your specific position with a qualified tax adviser before a material transfer.

Cambridge Currencies is authorised by the Financial Conduct Authority (FCA reference 900170) and works exclusively with FCA-authorised payment partners — Currencycloud (FRN 900199) and ScioPay (FRN 927951).
