GBP/EUR is the highest-volume cross-border currency corridor for UK businesses, yet the cost of executing this conversion is one of the least scrutinised line items in most finance functions. Businesses that would never accept a 1.5% fee on a supplier invoice routinely absorb a 1.2–1.8% spread on their GBP/EUR bank conversion without realising it — because the cost is embedded in the exchange rate applied rather than shown as a fee.
Post-Brexit, the structural cost of GBP/EUR payments has increased. The UK's exclusion from the SEPA zone changed the regulatory framework governing charges for cross-border EUR payments involving UK institutions, and several of the low-cost payment channels that UK businesses previously used have either become unavailable or more expensive. Understanding exactly where the cost sits and how to minimise it is now a material treasury management task.
The Post-Brexit SEPA Landscape
Before Brexit, UK banks and payment institutions were full participants in SEPA (Single Euro Payments Area), the EU's harmonised EUR payment system covering 36 countries. UK businesses sending EUR payments to European counterparties could use SEPA Credit Transfer (SCT) and SEPA Instant Credit Transfer (SCT Inst) — low-cost, fast settlement channels governed by the EU's Payment Services Directive (PSD2).
Post-Brexit, UK institutions are no longer full SEPA participants. Most UK banks and FCA-authorised payment firms maintain correspondent bank relationships with EU counterparties to access SEPA rails indirectly. This works in practice, but it adds at least one additional correspondent banking layer and associated fees compared to the pre-Brexit structure. The UK's PSR (Payment Systems Regulator) has no jurisdiction over SEPA charges applied by EU correspondents.
However — and this is the important nuance — some FCA-authorised firms, including several EMIs such as CCYFX, maintain EU subsidiary entities or EEA passported relationships that allow direct SEPA access. This means GBP/EUR payments through specialist payment firms can still achieve SEPA-level costs and settlement speeds, while the same payment through a UK clearing bank may take an extra day and cost significantly more.
Anatomy of a GBP/EUR Payment Cost
A business sending £100,000 to a German supplier incurs costs in several components, most of which are invisible:
FX Conversion Spread
If the mid-market GBP/EUR rate is 1.1850 and the bank applies 1.1680, the effective spread is 143 pips — approximately 1.2%. On £100,000, this is £1,200 extracted in the conversion before any fees are applied. Most business banking customers have no visibility into this spread unless they specifically request it and compare to the mid-market rate at the same moment.
Transfer Fees
Banks typically charge £15–50 for international transfers plus a lifting fee charged by the receiving bank (typically €10–30 on SEPA; higher on SWIFT). These are visible on the debit advice but rarely aggregated into a per-transaction cost analysis.
Cut-Off Time Risk
This is a hidden cost that finance teams rarely quantify. If a GBP/EUR SWIFT payment submitted at 2pm in London misses the bank's same-day processing cut-off, the conversion may be executed the following morning at a different rate. The exchange rate risk in this 12–18 hour window is a cost that sits in FX P&L, not in the payment fee line.
Benchmarking Your Current Costs
The simplest benchmarking exercise is to pull three months of GBP/EUR payment transactions, identify the rate applied to each, and compare to the ECB reference rate at the time of execution. The ECB publishes daily EUR reference rates for all major currencies, including GBP/EUR, on its website. The gap between the ECB reference rate and your bank's applied rate is your effective conversion cost. For most businesses using corporate banking FX services, this gap will be 0.8–2.0%.
The same exercise comparing to the rates available from specialist payment providers — which typically offer 0.10–0.35% spreads for GBP/EUR at business volumes above £100,000 per transaction — will quantify the annual saving available from switching. For a business converting £2 million per month in GBP/EUR, the saving from moving from 1.5% to 0.2% is approximately £26,000 per month.
Settlement Speed and Operational Risk
Beyond cost, GBP/EUR settlement speed matters operationally. Supplier payment terms are set in EUR but the UK business pays in GBP — a 2-day settlement window creates a timing mismatch that can result in early payment discounts being missed or late payment charges being incurred. SEPA Instant Credit Transfer (available 24/7, settlement within 10 seconds for amounts up to €100,000) has become increasingly available through specialist EMIs and dramatically reduces this operational risk.
For high-frequency GBP/EUR flows — such as iGaming operators paying out player winnings to European bank accounts — the operational benefit of near-instant EUR settlement is as significant as the cost saving, since player experience is directly tied to withdrawal speed.
