How UK businesses, agencies, and freelancers can reduce the hidden FX cost of regular payments to Spain.
If you work with contractors, freelancers, or suppliers based in Spain, you're likely making regular GBP → EUR transfers. Over time, the method you use to send those payments can cost significantly more than it needs to — not because of visible fees, but because of the exchange rate margin applied each time.
A single large transfer is relatively easy to optimise — you compare a few providers, pick the best rate, and move on. Regular monthly payments are different:
The hidden cost problem: A 2–3% exchange rate margin doesn't sound like much. On a £3,000 monthly contractor payment, it adds up to £720–£1,080 per year — paid silently to your bank.
| Method | Typical issue | Rough annual cost on £3k/month |
|---|---|---|
| UK bank SWIFT transfer | Exchange rate margin of 2–4% + flat fees | £720–£1,440+ lost to spread |
| PayPal | High conversion fees, poor FX rate | Often 3–4% total cost |
| Wise (business) | Transparent fee ~0.5%, mid-market rate | ~£180 in fees, no hidden spread |
| Revolut (business) | Plan-dependent, good within limits | Depends on plan and volume |
Figures are illustrative. Exact costs depend on provider, amount, and timing.
Three variables determine what your contractor payments actually cost:

For most businesses, a specialist provider like Wise Business is significantly cheaper than a UK bank for regular GBP to EUR payments. The main saving comes from the exchange rate — banks typically apply a 2–4% margin, while Wise charges around 0.5% with no hidden spread. On a £3,000 monthly payment, that difference can exceed £1,000 per year.
Not necessarily — many sole traders and freelancers use personal accounts for contractor payments. However, using a dedicated business account (Wise Business, Revolut Business) can simplify bookkeeping, provide cleaner transfer records, and may offer better rates or higher limits for regular international payments.
You need the contractor's Spanish IBAN (starts with ES, 24 characters) and their bank's BIC/SWIFT code. Some providers also ask for the recipient's name and address. EUR payments to Spain typically route via SEPA, so the process is usually straightforward once you have the IBAN.
This is worth agreeing in advance with your contractor. Invoicing in EUR means your contractor knows exactly what they'll receive and you carry the FX risk. Invoicing in GBP means you know your cost but the contractor's EUR amount varies with the rate. Either approach works — the more important factor is using a low-margin provider for the conversion.
