A money exchange comparison weighs four things — the exchange rate (and the margin baked into it), any fees, the transfer speed, and the regulatory protection of the provider. For larger amounts (typically £10,000 and above), specialist currency brokers usually deliver materially more on the same transfer than high-street banks because their FX margins are tighter; for small, fast personal transfers, money transfer apps are often the more practical choice.
Who this guide is for
If you’re moving £10,000 or more — for a property abroad, an inheritance transfer, a business payment, a salary repatriation or selling an overseas asset — the cost of getting the comparison wrong is real. On a £100,000 transfer, the difference between a typical high-street bank and a specialist broker can run into thousands of pounds. This guide explains exactly what to compare, what to ignore, and how the main provider types stack up.
What “money exchange comparison” actually means
A money exchange comparison is the process of evaluating different currency providers — banks, specialist brokers, online money transfer apps and peer-to-peer services — across the four factors that determine the real cost of an international transfer: exchange rate margin, fees, settlement speed, and regulatory standing.
The single most common mistake is comparing fees alone. A “no fee” provider with a 2% margin built into the exchange rate will cost you far more on a large transfer than a broker charging a small fixed fee with a 0.3% margin. The headline fee is rarely the headline cost.
How money exchange providers compare
The market splits into four broad types. Each has a use case where it makes sense, and each has trade-offs.
| Provider type | Typical FX margin | Fees | Best suited to | Trade-offs |
|---|---|---|---|---|
| High-street banks(NatWest, Lloyds, Santander, Barclays, HSBC) | ~2–4% above interbank | Often £0–£25 per transfer | Convenience, very small transfers | Wide FX margins; rates often not shown until execution |
| Specialist currency brokers (Cambridge Currencies and similar) | ~0.2–0.7% above interbank on larger amounts | Typically £0 on large transfers | Property purchases, business FX, large personal transfers | Phone-based service rather than instant app; minimum transfer thresholds |
| Online money transfer apps (Wise, Revolut, OFX) | ~0.4–1.5% depending on currency and amount | Variable, often percentage-based | Small to medium personal transfers, frequent low-value transfers | Margins widen on less-liquid currencies; limits and costs scale poorly with size |
| Card and peer-to-peer services (PayPal, Western Union) | ~3–5%+ above interbank | Variable, sometimes high | Urgent cash pickup, very small transfers | Among the most expensive options for transfers above a few thousand pounds |
These ranges are indicative and reflect typical pricing patterns observed by Cambridge Currencies across the UK currency market. Actual margins vary by currency pair, transfer size, market conditions and individual provider policy.
A worked comparison: £25,000 GBP to USD
The chart below illustrates a single, indicative snapshot of what £25,000 converted to US dollars produced across five providers on the same day, at the same time, on the same GBP/USD interbank rate.
In this example:
- Cambridge Currencies delivered $31,045
- NatWest delivered $30,617 — a difference of $428
- Lloyds delivered $30,315 — a difference of $730
- Santander delivered $30,275 — a difference of $770
- PayPal delivered $29,812 — a difference of $1,233
This is a single point-in-time comparison and rates fluctuate continuously. The pattern, however, is consistent across most large-transfer corridors: high-street banks and card-based services apply wider FX margins than specialist brokers. As Anthony Bull, CEO of Cambridge Currencies, puts it: “Clients who’ve never compared their bank against a broker are usually surprised by the difference. On a property transfer, that gap is the difference between a new kitchen and no new kitchen.”
For the live interbank rate to compare against, the European Central Bank reference rates and Bank of England daily spot rates are the cleanest public benchmarks.
What to compare — the four factors that actually matter
1. The exchange rate (and the margin behind it)
The exchange rate you’re quoted is the interbank “mid-market” rate plus a margin. Most providers don’t disclose the margin directly; you have to infer it by comparing the quoted rate to the live interbank rate. A 0.3% margin on £100,000 is £300; a 2.5% margin is £2,500. This is almost always the largest single cost in any transfer.
2. Fees
Fees are usually the smallest cost — often £0 to £25 per transfer with most providers. Specialist brokers typically charge no transfer fee on amounts above a threshold (commonly £3,000–£10,000). Banks vary. Don’t let a “no fee” headline distract you from the margin.
3. Transfer speed
Most major-currency transfers settle the same day or next business day. Some providers can offer same-day settlement for time-critical transfers like property completions, but only if instructions are received before cut-off. Always check the cut-off time, particularly for SWIFT-routed payments.
4. Regulatory protection
For UK senders, the relevant regulator is the Financial Conduct Authority. Any reputable provider should be either FCA-authorised in their own right or operating through FCA-authorised partners with client funds safeguarded. Cambridge Currencies operates with FCA-authorised partners Currencycloud (FRN 900199) and ScioPay (FRN 927951), with all client funds held in safeguarded accounts.
When each provider type makes sense
Use a high-street bank if you’re sending a small one-off transfer, prioritise familiarity over cost, or your bank’s margin happens to be competitive on your specific corridor (rare but possible on major pairs).
Use a specialist currency broker if you’re transferring £10,000 or more, buying or selling property abroad, paying overseas suppliers as a business, repatriating funds, or you want forward contracts to lock in a rate ahead of a future transfer. The savings on margin compound at scale, and you get a named specialist who understands the corridor.
Use a money transfer app if you’re sending small amounts regularly, want app-based convenience, or are transferring between currencies and accounts you already manage in those apps.
Use a card or peer-to-peer service if the recipient needs cash pickup or you’re sending a very small amount where speed and convenience outweigh the cost.
Why specialist brokers are usually better for large transfers
For amounts above £10,000, three things shift the maths in favour of brokers:
- Margins compress at scale. A specialist quoting 0.3% above interbank on a £200,000 property purchase costs £600 in FX margin. The same transfer through a bank at 2.5% costs £5,000. The fee difference is rounding error against this.
- Forward contracts protect you. A forward contract locks today’s rate for a transfer up to 12 months in the future — useful when you’ve agreed a property price in euros but won’t complete for six months. Most banks don’t offer them to retail clients.
- You get a named specialist. International transfers are detail-heavy: SWIFT codes, intermediary banks, reference fields, beneficiary information, regulatory thresholds. Phone-based broker service catches errors before they cost you a settlement delay or a returned payment.
In Cambridge Currencies’ experience working with property buyers in Spain, France and Italy, the most common reason clients move from a bank to a broker isn’t the rate — it’s the realisation that nobody at the bank actually knows their transfer.
Common mistakes when comparing money exchange providers
- Comparing fees, not margins. As above — fees are usually the smaller cost. Always check the rate against the live interbank rate.
- Trusting Google’s exchange rate as a quote. The rate Google shows is the interbank mid-market rate. No provider gives you that rate; the question is how close they get to it.
- Choosing on speed when speed isn’t the constraint. Most non-urgent transfers are not time-critical to the hour. Paying 2% extra to save four hours rarely makes sense.
- Not asking about forward contracts. If your transfer is for a future commitment (property completion, tuition payment, business invoice), you can fix the rate now. Most clients don’t realise this is an option.
- Assuming all “regulated” providers are equivalent. Check what kind of authorisation the provider holds, and whether client funds are safeguarded.

Frequently asked questions
What’s the best way to compare money exchange providers?
Compare the all-in cost of moving a specific amount: the exchange rate quoted (against the live interbank rate), any fees, and the settlement speed. Margin is almost always the largest cost on transfers above £5,000.
How much can I save using a currency broker compared with a bank?
On a £100,000 transfer, the difference between a typical high-street bank and a specialist broker is commonly in the range of £1,500–£3,000, depending on the currency pair and market conditions. On smaller transfers the gap narrows.
Are currency brokers regulated in the UK?
Reputable currency brokers are either authorised by the Financial Conduct Authority directly or operate through FCA-authorised partners. Cambridge Currencies operates with Currencycloud (FRN 900199) and ScioPay (FRN 927951) and safeguards client funds.
Do specialist brokers charge fees on large transfers?
Most specialist brokers, including Cambridge Currencies, charge no transfer fee on amounts above a set threshold. The cost is built into the exchange rate margin, which is typically much tighter than a bank’s.
Can I get the same exchange rate I see on Google?
No. The rate on Google, Reuters or XE is the interbank mid-market rate — the rate banks lend to each other at. Every consumer-facing provider applies a margin. Specialist brokers typically get closer to the interbank rate than banks or card providers.
How long do international currency transfers take?
Major-currency SWIFT transfers usually settle the same day or next business day if instructions are received before cut-off. Same-day settlement is common for major pairs like GBP/USD and GBP/EUR; less-liquid currencies can take longer.
What’s a forward contract and when should I use one?
A forward contract is an agreement to buy currency now at today’s rate but settle on a future date — typically up to 12 months out. It’s used to fix the exchange rate on a known future transfer, such as a property completion or scheduled business payment.
Why is it worth speaking to a specialist for large transfers?
Large transfers have execution detail that affects the outcome — SWIFT routing, intermediary banks, reference fields, regulatory reporting thresholds. A named specialist catches errors before they cost a settlement delay and can structure the transfer (forward contract, market order, split execution) to manage rate risk.
Speak to a specialist about your transfer
If you’re planning a property purchase abroad, a business payment, or any transfer above £10,000, it’s worth comparing your bank’s quote against a specialist broker before you execute. Request a quote from Cambridge Currencies and a specialist will walk you through the live rate, the all-in cost, and the options for managing rate risk on the transfer. All transactions are completed by phone with a dedicated specialist who stays with you from first quote to settlement.
