Key Takeaways

  • ✓ The cost of a currency transfer is mostly the spread, the margin baked into the rate, not the advertised fee. "Zero commission" tells you almost nothing.
  • ✓ A one per cent difference in the rate on a €229,000 purchase is €2,290, more than the notary and land registry combined.
  • ✓ Your price is fixed in euros at the arras. Your money is not, and completion is typically weeks or months later.
  • ✓ A forward contract fixes the rate for a future date. It is insurance against movement, not a bet: you must complete the trade either way.
  • ✓ At the median of our 400k–600k band (€483,000, 529 live properties) a three per cent swing is €14,490.

If your money is in pounds, kronor, krone or dollars and your purchase is in euros, currency is a real line item in the cost of buying, and it is the only one nobody itemises for you. On a €229,000 property, the median of the band where we hold 104 live listings, a one per cent difference between two providers is €2,290. That is more than the notary and land registry fees put together. This article explains how the pricing works so you can compare quotes properly. It is general information about how the market operates, not financial advice, and we do not recommend a provider.

Spread versus fee: where the cost actually is

There is a wholesale exchange rate, the interbank or mid-market rate, that you will see quoted on any news site. Nobody offers it to retail customers. Every provider adds a margin, and that margin is the spread. It is invisible, because it is expressed as a slightly worse rate rather than as a charge.

On top of that, some providers add a transparent transfer fee. Here is the trap: a provider advertising "no fees, no commission" may have a wider spread than one charging a flat fee with a tight spread, and end up considerably more expensive. The fee is the small number you can see. The spread is the large number you cannot.

The fix is simple and it works every time. Ignore the fee, ignore the headline rate, and ask one question: "For exactly £X, how many euros will land in the destination account, after everything?" Get that figure from two or three providers within the same few minutes, because the market moves. The largest number wins. There is no other comparison worth making.

Two details to include in that question. Ask whether the receiving bank will deduct anything at the other end: charges can be shared or paid wholly by the sender, and the difference matters. And ask whether they can send to a Spanish notary or lawyer client account, which is where the money often needs to go.

What a rate move is worth at our price points

Currency movement is proportional, so the exposure scales directly with the purchase. Using the median of each of our live price bands:

Band (live properties)Band medianA 1% moveA 3% move
€200k–€250k (104)€229,000€2,290€6,870
€250k–€300k (156)€275,000€2,750€8,250
€300k–€400k (361)€349,900€3,499€10,497
€400k–€600k (529)€483,000€4,830€14,490
€600k–€1m (423)€782,700€7,827€23,481

The percentages above are illustrative, not forecasts. We have no idea what the rate will do, and neither does anyone selling you a rate. The point is only the scale. On a €483,000 purchase, a three per cent move is roughly the cost of furnishing the property.

The exposure window nobody plans for

Here is the sequence that creates the risk. You agree a price in euros. You sign the arras and pay a deposit, customarily around 10%, converting that portion at today's rate. Then you wait: typically weeks for a resale, and potentially many months for an off-plan new build with staged payments. At completion you convert the remaining 90% at whatever the rate happens to be that week.

Nothing about that is unusual and it is not a disaster. But it means the sterling cost of your Spanish house is not known on the day you agree it. If your budget has no headroom, that is a problem you should solve deliberately rather than discover at the notary. See the arras contract guide for what fixes the euro price and when.

Forward contracts, in plain language

A forward contract is an agreement to exchange a set amount at a rate fixed today, for settlement on a future date. Currency brokers offer them routinely for property purchases, typically out to twelve months or so. The mechanics:

  • You lock the rate now for a stated amount and a stated settlement window.
  • You pay a deposit up front, a margin that is usually a percentage of the total, and the balance on or before maturity.
  • You must complete the trade. A forward is an obligation, not an option. If the rate moves in your favour, you do not benefit.
  • The provider may ask for more margin if the market moves substantially against your locked position before settlement. Ask what would trigger that and how much notice you would get, before you sign.

The honest framing: a forward is not a way to make money on currency. It is a way to convert an unknown cost into a known one, so that the price you agreed is the price you pay. Whether that certainty is worth giving up a possible favourable move is a judgement about your own budget, not a market call. If a three per cent move would genuinely hurt you, certainty is probably worth having. If it would not, the flexibility may be.

Two related tools you may be offered: a limit order, which executes automatically if the rate reaches a level you specify, and a stop-loss, which executes if it falls to a floor you set. Both are ways of automating a decision you have already made. Neither predicts anything.

Choosing a provider, without us naming one

We are not going to recommend a company, and you should be wary of any agency that does. Referral arrangements are common in this industry and they are not always disclosed. Judge for yourself against this list:

CheckWhy it matters
Properly regulated in your countryPayment institutions and e-money firms are authorised and listed on a public register. Look them up yourself
Client funds safeguarded or segregatedYour money should not sit in the firm's working capital
A written quote showing euros deliveredThe only number that allows a real comparison
Clear on receiving-bank chargesAsk who pays them and how much lands at the far end
Can pay a Spanish notary or lawyer client accountNot every provider will send to a third-party account
No pressure to time the marketA "relationship manager" urging you to move today is a sales tactic
Source-of-funds process explained up frontAnti-money-laundering checks are mandatory. Start them early

That last one causes more delayed completions than the exchange rate ever does. Spanish banks and notaries must document where the money came from. Assemble the evidence (sale of a property, pension release, savings history, inheritance documentation) at the start of the process, not the week before completion.

The fraud that actually costs buyers money

Currency risk is a cost. Payment redirection is a loss. The pattern is consistent: an email arrives, apparently from your lawyer or the agency, saying the bank details have changed and giving new ones. The buyer transfers. The money is gone within the hour and is very rarely recovered.

The defence is boring and absolute. Verify every set of bank details by voice, on a number you already had, before every transfer, including the second and third ones. Never accept details that arrive only by email, never call a number contained in that email, and be suspicious of any change of account at short notice. This and the other patterns are in Spanish property scams.

Getting the money there on the day

Spanish notaries record the means of payment in the deed, and for the balance at completion a bank cheque (cheque bancario) drawn on a Spanish account is what many will expect. That means the funds need to be in a Spanish account, cleared, several days before the appointment, not in transit on the morning. Ask your lawyer what the specific notary requires, then work backwards and add a buffer. A transfer stuck in compliance checks is the classic reason a completion date slips.

Where the numbers get big enough to matter

These four sit in the bands where a few per cent of currency movement is a serious sum: between roughly €320,000 and €445,000, where a three per cent swing is around €10,000 to €13,000.

What we would do

Get three all-in quotes on the same morning and take the biggest euro figure. Decide consciously whether to fix the rate for completion or accept the movement, based on how much headroom your budget has, not on anyone's forecast. Start the source-of-funds paperwork the week you agree a price. And verify every account number by voice, every time.

None of that is sophisticated, and together it is worth more than most of the other cost savings in a purchase. The rest of the arithmetic is in the true cost of buying property in Spain, and if you are buying from Britain, the post-Brexit guide covers what else changed.
