The safest way to send a large sum of money overseas is through a currency provider whose payment partners are authorised by a financial regulator such as the FCA, which keeps client funds in segregated, safeguarded accounts. Independently verify every bank detail before you transfer, lock your exchange rate where the timing matters, and move funds in a way you can trace end to end. This guide explains how to do that for any currency and any corridor — whether you are sending pounds, dollars, euros, naira, rand or cedi, and whether the money is leaving the UK or arriving into it.
Sending £100,000, $250,000 or the equivalent for a property purchase, a business settlement or family support is not the same as sending £200 to a friend. The rate matters, but security matters more: a large transfer that goes to the wrong account, or sits with an unprotected provider that fails, can be unrecoverable. This is a Your Money or Your Life decision, and it deserves a deliberate process rather than a quick app tap.
Who this guide is for
This guide is for anyone moving a high-value sum across borders: property buyers settling on a home abroad, expats repatriating savings or a pension, businesses paying overseas suppliers or receiving large client payments, and families sending or receiving inheritance and support. It applies to outbound transfers from the UK and to inbound transfers into the UK from markets including the United States, Nigeria, South Africa, Ghana, Kenya, Australia and the eurozone — our send money to the UK corridor hub covers the major routes. The principles are universal; only the corridor and currency change.
What counts as a “large” transfer, and why it changes the rules
There is no single legal threshold, but in practice anything from around £10,000 upwards behaves differently from a small payment. Banks apply tiered margins, brokers waive transfer fees, compliance checks become mandatory, and the cost of a poor exchange rate scales with the amount. On a £500,000 transfer, a 2% bank margin is £10,000 — and the reason banks give worse rates is structural, not incidental. That difference is no longer trivial; it is the price of a small car or a year of school fees.
Large sums also attract fraud. According to UK Finance, authorised push payment (APP) fraud losses reached £257.5 million in the first half of 2025, a 12% rise year on year, with investment scams — which typically involve larger amounts — up 55%. APP fraud, where a victim is tricked into authorising a payment to a criminal, is hard to reverse precisely because the customer authorised it. High-value international transfers are a prime target.
Key principles for sending large sums securely
- Use a provider whose payment partners are regulated. In the UK, that means FCA-authorised. Regulated firms must keep client funds in segregated accounts, follow strict auditing, and safeguard money so it can be returned if the firm fails.
- Independently confirm all bank details before sending — by phone to a known number or in person, never from an email alone.
- Secure your accounts and communications with strong, unique passwords and two-factor authentication.
- Watch for red flags: urgency, last-minute changes to account details, and unusual payment requests.
- Work with a provider that offers direct, personal support — a named human you can call to confirm a payment is far harder for a fraudster to impersonate than a faceless online form.
How should I choose a provider for a large international transfer?
The single most important decision is who handles your money. Your options fall into three broad categories, each with honest trade-offs.
| Feature | High-street bank | Money transfer app | Specialist currency broker |
|---|---|---|---|
| Exchange rate margin | Often 2–4% above interbank | ~0.4–1% | Typically 0.3–0.8% |
| Transfer fees | Per-transfer charges common | Low, sometimes capped | Usually none on large sums |
| Speed | Several days | Minutes to days | Same or next day for major currencies |
| Personal support | Generic call centre | App-based, limited | Named, 1-to-1 specialist |
| Rate tools | Limited | Some | Forward contracts, market orders, rate alerts |
| Best suited to | Existing customers prioritising familiarity | Smaller, frequent transfers | High-value and time-sensitive transfers |
For very large or time-sensitive sums, a specialist broker usually combines the keenest rate with the most hands-on security — and the ability to lock a rate in advance, which an app generally cannot offer. Our exchange rate comparison tool shows how broker rates stack up against the high street. As Anthony Bull, CEO of Cambridge Currencies, puts it: for a six-figure transfer, the rate gets you in the door, but it is the human verification and the safeguarded client account that actually protect the money.
Why a specialist broker matters for high-value transfers
A bank treats a £500,000 transfer the same way it treats a £500 one — same generic process, same wide margin, same call-centre queue. A specialist applies a tighter margin, confirms the beneficiary details with you directly, and stays on the line through settlement. For property and business deadlines, that combination of price and personal oversight is the differentiator. Cambridge Currencies operates entirely by phone, with a dedicated specialist on every transfer — a deliberate security feature, not a limitation.
What does “FCA authorised” and “safeguarding” actually mean?
Safeguarding is the regulatory requirement for a payment firm to keep customer money separate from its own funds, in a segregated account, so the money can be returned if the firm fails. It is the core protection behind any large transfer made through a regulated provider.
Unlike a UK bank deposit, money held by a payment or e-money firm is not covered by the Financial Services Compensation Scheme (FSCS). Instead, the firm must safeguard it. That distinction matters: with safeguarding, your funds are ring-fenced from the firm’s creditors, but the protection depends entirely on the firm following the rules correctly. Our guide to what FCA regulation means for FX clients explains how this works in practice.
This regime has just become significantly stronger. From 7 May 2026, the FCA’s new safeguarding rules (set out in Policy Statement PS25/12) require payment and e-money firms to carry out daily reconciliations of safeguarded funds, file monthly returns to the regulator, undergo annual audits, and maintain a resolution pack so client money can be returned quickly if the firm fails. The reforms followed evidence that, when firms failed historically, customers recovered on average only around 35 pence in the pound — which is exactly why checking your provider’s regulatory standing is not box-ticking.
Cambridge Currencies is not itself an FCA-authorised institution. It arranges transfers through FCA-authorised payment partners — Currencycloud (FRN 900199) and ScioPay (FRN 927951) — and it is through those partners that client funds are safeguarded. You can read exactly how fund safeguarding works at Cambridge Currencies, or verify any firm’s authorisation directly on the FCA Financial Services Register. For a real-world reminder of why this matters, our analysis of the Argentex administration shows what can happen when an FX provider fails.
How to check a provider yourself: Search the firm (or its named payment partner) on the FCA Register, confirm the Firm Reference Number matches, and check that “safeguarding” appiles to its permissions. If a provider cannot tell you who safeguards your money, treat that as a red flag.
How do I avoid fraud on a large transfer?
Most high-value losses are not technical hacks — they are social engineering. The two scenarios below account for the bulk of large-transfer fraud.
Payment diversion (invoice and conveyancing fraud)
A criminal impersonates your solicitor, supplier or estate agent and supplies different account details, usually by email, often close to a deadline. You believe you are paying the right party. This is the dominant risk in overseas property purchases, where a large sum moves to a fixed completion date.
Defence: Always verify account details using a phone number you already have — from a signed contract or an official website — never a number or link in the email itself. Confirm any change in details by voice before paying a penny.
Phishing and provider impersonation
Scammers send emails posing as your transfer provider, prompting you to “confirm” details or log in via a fake link.
Defence: Never click links in unexpected emails. Type the provider’s address yourself, enable two-factor authentication, and use a unique password for each financial service. A provider that confirms instructions by phone with a known specialist removes most of this risk.
Red flags to watch for
| Warning sign | What to do |
|---|---|
| Sudden change in bank details | Stop. Verify by phone to a known number or in person |
| Pressure to transfer urgently | Step back; legitimate deadlines survive a verification call |
| Request for unusual payment methods | Decline — no genuine firm asks for gift cards or crypto to “hold” a property |
| Vague or evasive communication | Choose a provider offering direct, named support |
| Email-only contact, no phone option | Be cautious of any large transfer you cannot confirm by voice |

Step-by-step: how a large international transfer works
Genuinely step-by-step, this is the process for moving a high-value sum safely through a specialist:
- Open an account with a regulated specialist currency broker and complete identity and source-of-funds checks. Having documentation ready up front prevents compliance delays at settlement.
- Agree your rate. Lock it with a spot deal for an immediate transfer, or a forward contract if you are paying on a future date and want to fix the rate now.
- Verify the beneficiary details independently — directly with your solicitor, supplier or recipient, by phone to a known number.
- Send your funds to the provider’s segregated, safeguarded client account.
- The provider converts and sends the money to the recipient’s bank via SWIFT (for most currencies) or SEPA (within the eurozone).
- Track the transfer. Request an MT103 — the SWIFT confirmation document — to trace the payment through the banking chain if it has not arrived on time.
Costs, exchange rates and hidden charges to watch for
On a large transfer, the exchange rate margin dwarfs every other cost. Providers rarely advertise the margin; it is built into the rate you are quoted versus the “interbank” or mid-market rate. The table below shows why this is where your attention belongs.
| Sum transferred | At 2.5% bank margin | At 0.5% broker margin | Difference |
|---|---|---|---|
| £50,000 | £1,250 | £250 | £1,000 |
| £250,000 | £6,250 | £1,250 | £5,000 |
| £500,000 | £12,500 | £2,500 | £10,000 |
Other costs to check: per-transfer fees (often waived by brokers on large sums but charged by banks), intermediary or correspondent bank charges on SWIFT payments, and the receiving bank’s own fees. Always ask whether your quote is “all-in” and whether the recipient will receive the full amount or a sum reduced by intermediary deductions.
Timing and currency risk on large transfers
Exchange rates move constantly. On a £500,000 transfer, a 2% swing between agreeing a price and settling is £10,000 — gained or lost on timing alone. For any large sum with a future date attached, the risk is real and worth managing rather than ignoring. If your transfer involves the most-traded routes, our live GBP/EUR and GBP/USD pages track the rate and the drivers behind it.
Three tools help, and a specialist can explain how each fits your situation:
- Spot contract — convert at today’s rate for near-immediate transfer. Simple, best when you are ready to move now.
- Forward contract — fix today’s rate for a transfer up to many months ahead, useful when you know a completion or invoice date but want certainty on cost.
- Market order — target a specific rate; the transfer executes automatically if the market reaches it.
The right approach depends on your deadline and your tolerance for movement. A specialist offers guidance on the trade-offs; the decision remains yours.
Common mistakes to avoid
- Chasing the rate and ignoring the provider’s protection. A marginally better rate from an unregulated firm is a false economy if the money is at risk.
- Trusting emailed account details. The single most expensive mistake in property transfers. Verify by voice, every time.
- Leaving currency conversion to the last minute on a fixed deadline, with no rate locked.
- Assuming FSCS covers the transfer. It does not — safeguarding is the relevant protection, and it depends on the firm’s regulatory standing.
- Not requesting an MT103 when a transfer is delayed, leaving you unable to trace it.
FAQs
Is it safe to transfer £100,000 or more internationally?
Yes, provided you use a provider whose payment partners are regulated (FCA-authorised in the UK), keep funds safeguarded in segregated accounts, and you independently verify all beneficiary details before sending.
What is the safest way to send money for a property purchase abroad?
Use a regulated specialist and verify the receiving account directly with your solicitor by phone to a known number. Consider a forward contract to fix your rate ahead of completion so the cost cannot move against you. Our guide to buying property abroad covers the currency side in full.
Are large international transfers protected by the FSCS?
No. Money held by payment and e-money firms is not covered by the Financial Services Compensation Scheme. Instead it must be safeguarded — kept in segregated accounts so it can be returned if the firm fails. From 7 May 2026, FCA safeguarding rules require daily reconciliation, monthly reporting and annual audits.
Can I track a large international transfer?
Yes. Request an MT103 reference, which is the SWIFT confirmation that lets you trace the payment through the correspondent banking chain if it does not arrive on time.
How much can I save using a broker instead of a bank?
On a £250,000 transfer, the difference between a typical 2.5% bank margin and a 0.5% broker margin is around £5,000. The larger the sum, the larger the saving.
Is there a limit on how much money I can send overseas?
There is no legal cap on personal international transfers from the UK, but large sums trigger mandatory identity and source-of-funds checks, and amounts may be reported to authorities for anti-money-laundering purposes. Having documentation ready prevents delays.
How do I check a provider is genuinely regulated?
Search the firm or its named payment partner on the FCA Financial Services Register, confirm the Firm Reference Number matches, and verify safeguarding is within its permissions. A provider that cannot name who safeguards your money is a warning sign.
Can I send money into the UK from abroad the same way?
Yes. The same principles apply to inbound transfers from the US, Nigeria, South Africa, Ghana, Kenya, Australia and elsewhere — use a regulated provider, verify details, and lock your rate where timing matters.
