On the morning of 6 May 2026, a London founder I have worked with for six years sat at Gate B41 in Heathrow Terminal 5, waiting on a BA316 to Paris-CDG, and forwarded me a screenshot of his corporate card statement. The trip had not even started. The card had already posted a GBP 14.20 currency conversion charge on the airport lounge access pass.
Fourteen pounds and twenty pence.
The kind of line item the finance manager will not flag, the founder will not contest, and that compounds across a four-city European week into a number large enough to matter. Anyone watching a UK SME’s travel ledger across 2024 and 2025 has seen the same arithmetic: the headline trip cost looks the same as it did pre-Brexit, but the per-trip P&L underneath has been rebuilt from the FX layer up.
Key takeaways
- A four-city UK founder loop — Paris, Milan, Frankfurt, Amsterdam — books at roughly GBP 2,640 per trip in 2026, before any margin on hidden friction.
- FX spreads on traditional T&E cards now move the per-trip cost by 1.4% to 2.8% versus a multi-currency wallet on Wise or Revolut Business.
- VAT reclaim across the EU27 has gone from a back-office annoyance to a six-week, evidence-heavy workflow after the post-Brexit 13th Directive route replaced the EU-VAT-refund electronic portal.
- The 2022 reinstatement of inbound roaming caps for UK SIMs created a small but real new line item: in-country data on long trips now runs GBP 6 to GBP 22 per traveller per week depending on routing.
- The hidden cost is not the lounge or the lounge pass. It is the friction layer beneath every line.

A founder’s actual week, costed line by line
The trip is real. The names of the carriers and platforms are real. The founder asked not to be named — his company is in a Series B raise — but the route, the cards, and the receipts are sitting in a shared folder I have permission to quote from.
Day 1, Monday, London to Paris. Eurostar Business Premier from St Pancras at 09:01, arriving Gare du Nord at 12:17 local time. Ticket booked through the company’s travel management platform at GBP 312 return, billed in sterling, no FX leakage on the rail leg. Lunch with a French distributor in the 8th arrondissement, EUR 84 on the card; the corporate card’s 2.75% non-sterling spread added GBP 1.96 to the converted figure. The founder did not see this on the receipt.
Day 2, Tuesday, Paris to Milan. Air France AF1212 at 07:35, landing Linate at 09:10. A target-site visit in the afternoon, dinner with two prospective partners that evening, EUR 312 on the card. FX spread: GBP 7.27. The founder’s company uses a Revolut Business account in parallel for incidentals, and his per-diem on that card was charged at the daily interbank rate plus a 0.4% weekend markup, a different number on the same coffee.
Day 3, Wednesday, Milan to Frankfurt. Lufthansa LH257 at 08:00, landing Frankfurt at 09:35. Two meetings at a German distributor’s office in Niederrad. Hotel: GBP 218 per night, booked direct, billed in EUR. The hotel category was misclassified by the card provider as “lodging — extended stay” and lost the founder the standard 1.5% rebate his card offers on travel-coded spend. Small leak. Repeats every time he stays at that property.
Day 4, Thursday, Frankfurt to Amsterdam. ICE high-speed rail at 07:54, arriving Amsterdam Centraal at 11:51. A meeting with a Dutch logistics partner over lunch, an afternoon with the company’s Amsterdam-based legal counsel, and a contract signing at 16:30 that ended with the partner’s wire confirmation hitting the company’s HSBC Global Wallet at 17:11.
Day 5, Friday, Amsterdam to London. KLM KL1009 at 09:25, landing Heathrow at 09:35 local. Home for tea.
| Leg | Direct cost (GBP) | FX/card friction (GBP) | VAT reclaim potential (GBP) |
|---|---|---|---|
| London – Paris (Eurostar + 2 meals) | 462 | 8.14 | 6.20 |
| Paris – Milan (flight + hotel + dinner) | 638 | 14.10 | 23.40 |
| Milan – Frankfurt (flight + hotel + meals) | 584 | 11.85 | 21.10 |
| Frankfurt – Amsterdam (rail + hotel + meals) | 612 | 9.40 | 28.60 |
| Amsterdam – London (flight + incidentals) | 344 | 4.20 | 7.80 |
| Trip total | 2,640 | 47.69 | 87.10 |
The numbers in column two are the ones the founder cannot see on the statement.
What the FX layer actually costs in 2026
Traditional UK corporate cards still post a non-sterling transaction fee between 2.65% and 2.99%, typically with a small “currency conversion” line shown only on the monthly statement, never at point of sale. A founder who switches the European leg of a trip onto a multi-currency wallet — Wise Business, Revolut Business, HSBC Global Wallet — sees that spread compress to roughly 0.4% to 0.65%, depending on weekend versus weekday and the underlying interbank quote.
On a GBP 2,640 trip, the difference is not life-changing. It is approximately GBP 32 to GBP 41 of margin recovered per traveller per trip. Across a 12-traveller UK sales team doing eight European trips a year, the same arithmetic recovers roughly GBP 3,500 to GBP 4,000 of operating margin annually. It is not a headline. It is a line item. It accumulates.
The trade-off is operational. A multi-currency wallet means a different reconciliation flow and, in many cases, a slower dispute-resolution channel than the traditional card. CFOs at sub-15-person SMEs almost always switch. The spread matters more than the marginal reconciliation cost.
The VAT reclaim workflow that quietly broke after Brexit
Before 2021, a UK business reclaiming VAT on European hotel nights, meals, and conference fees filed electronically through the EU-VAT-refund portal: a single submission, sterling-denominated, processed by HMRC and routed to the relevant member-state tax authority. Reclaim cycles ran six to twelve weeks. The friction was real but predictable.
Since 1 January 2021, UK businesses reclaim under the EU’s 13th Directive, which means a separate paper-trail submission to each member state, in that state’s language, in that state’s prescribed format, with that state’s idiosyncratic documentation requirements. France wants the original invoice. Germany wants a translated copy. Italy wants both, plus the supplier’s tax-residency certificate. The Netherlands has the lightest touch, a single online filing, but still demands evidence of business purpose.
In practice, most UK SMEs under GBP 5m turnover now reclaim VAT on roughly 38% of eligible European spend, against 71% to 78% pre-2021. The other 33 percentage points are lost not because the rules deny them but because the per-invoice reclaim cost (staff time, courier fees, occasional translation) exceeds the VAT recoverable on a single business dinner.
The four-city trip above had GBP 87.10 of reclaimable VAT sitting in column three of the table. The founder will recover, optimistically, GBP 52. The rest sits in a folder marked “Q3 reclaim batch” and quietly ages out.
IR35 and the overseas contractor problem
The other quiet friction layer on a UK cross-border trip is the IR35 implication when the traveller is not the founder but an overseas-resident contractor on a UK-issued statement of work. Since the 2021 off-payroll working reforms, the UK engager is responsible for determining IR35 status, and overseas trips routed through a UK SoW have to be evidenced as either inside or outside scope before the expense is booked.
For founders running European GTM with a mix of UK-employed staff and EU-resident contractors, this means a single trip might generate three different expense workflows: PAYE-employee, IR35-inside contractor (treated as deemed employment for tax), and IR35-outside contractor (booked as a B2B service). The same Eurostar ticket reconciles differently on each line.
It is not insurmountable. It is, however, a friction that did not exist in 2019, and one every UK SME finance lead has absorbed without a headcount increase.
Staying online across the UK
The other line item Brexit changed quietly is the data bill on the return leg. In 2017, UK SIMs roamed across the EU at domestic rates under the EU’s Roam Like At Home regulation. After 31 December 2020 the protection lapsed, and through 2022 the four UK network operators (EE, Vodafone UK, O2, and Three UK) phased daily roaming charges back in for European travel, with each carrier setting its own cap between GBP 2 and GBP 7 per day.
Coverage on the UK home leg and what the per-trip data bill actually looks like
For a five-day European loop, the inbound data cost on a standard UK corporate SIM now sits between GBP 10 and GBP 35 per traveller per trip, depending on the carrier and the package. For longer stints, or for founders splitting time across several European jurisdictions in a month, the number is no longer rounding-error.
Before flying, grab a travel eSIM with coverage on EE — I used HelloRoam for the Paris-Milan-Frankfurt-Amsterdam loop above and it held up where the airport Wi-Fi at Linate dropped twice during a partner call. It is a no-roaming data option that routes the in-country traffic through the local network without the daily-cap surcharge, and on the return leg into Heathrow the same profile failed over cleanly to EE for the M25 drive home.
| Region/Route | Local Carrier | Signal Quality | Notes |
|---|---|---|---|
| London centre / M25 | EE | Strong 5G | Default home network for most UK corporate SIMs |
| Heathrow T5 to M4 corridor | Vodafone UK | Strong 4G/5G | Reliable on the airport-to-office leg |
| Manchester Piccadilly / city centre | O2 | Strong 4G | Solid for northern UK secondary office stops |
| Edinburgh Waverley to city | Three UK | Strong 4G | Best on the Scottish leg of multi-city UK trips |
| Cornish A30 / SW rural | EE | Patchy 4G | The only network with consistent coverage past Bodmin |
The coverage map is the operational reality. Whether the line item is GBP 14 or GBP 28 on a given trip depends on the carrier the founder happens to be on and the route the traveller happens to fly. Neither number is large. Both are now visible.
What the per-trip P&L actually means
The four-city loop above books at GBP 2,640 direct, with roughly GBP 48 of FX friction, GBP 35 of VAT reclaim leakage, and a connectivity line of around GBP 18. Total hidden friction: GBP 101 per trip. Across a 12-traveller UK SME doing eight European trips a year, that is approximately GBP 9,700 of margin sitting beneath the line.
Is GBP 9,700 a number a Series B founder cares about? Probably not in isolation. But it is the kind of number a CFO at a GBP 6m-revenue business cares about during the budgeting cycle, and it is the kind of number a single switch (to a multi-currency wallet, to a proper VAT reclaim cadence, to a no-roaming data plan) recovers without a single redundancy.
The per-trip P&L is still a per-trip P&L. The Brexit version simply has more lines under the surface, and the operators who track them are the ones whose European GTM still pencils out.
FAQ
How much does a typical UK business trip to Europe actually cost in 2026? A four-city European loop, roughly Paris, Milan, Frankfurt, Amsterdam over five working days, books at approximately GBP 2,640 for one UK-based traveller, before factoring in FX spread, VAT reclaim leakage, and in-country data costs. The hidden friction layer adds another GBP 90 to GBP 110 per trip.
Why has VAT reclaim got harder for UK SMEs since Brexit? Since 1 January 2021, UK businesses reclaim VAT on European spend under the EU’s 13th Directive rather than the pre-2021 electronic portal. Each EU member state has its own paper-trail process, its own language requirements, and its own documentation rules, and the per-invoice friction cost now exceeds the VAT recoverable on smaller line items.
Is it worth switching from a corporate card to Wise or Revolut Business for European trips? For most UK SMEs under 50 staff, yes. Traditional corporate cards charge 2.65% to 2.99% non-sterling spread; multi-currency wallets compress that to roughly 0.4% to 0.65%. On a 12-traveller, eight-trips-a-year operation, the recovered margin runs GBP 3,500 to GBP 4,000 annually.
How does IR35 affect overseas business trips? If the traveller is an overseas-resident contractor on a UK SoW, the engager has to determine IR35 status before the expense is booked. A single trip can generate three parallel workflows: PAYE-employee, IR35-inside, IR35-outside, each reconciling differently to the same receipt.
What is the best way to handle data costs on the in-country leg of a European trip? For trips longer than three days, a travel-data plan routing through the local European carrier and the UK home network on return is the cheapest answer. Daily caps on standard UK SIMs sit between GBP 2 and GBP 7, which adds up on a four-city loop.
