10–15% is the rough “Travelex tax” regulars complain about
Travelex at London Stansted (STN) sits prominently in the terminal and in pre-flight searches, but frequent flyers talk about it like an airport minibar: there if you’re desperate, pricey if you’re not. Forum posts peg the effective hit to the rate at roughly 10–15% compared with decent online FX or ATM withdrawals. Desks run long hours in the departure area and arrivals, so the temptation is always in your line of sight.
Rates at Stansted’s Travelex counters track the same pattern seen across UK airports: marked-up margins, extra fees hidden in the spread, plus sales pitches for prepaid currency cards. One TripAdvisor user flatly called airport bureaus “by far the worst” option, only using them as an absolute last resort. Buyback services for leftover euros or dollars are also called out for weak rates, so many people just keep small balances for their next trip instead of selling back at STN.
ATMs with Travelex branding around Stansted introduce another trap: dynamic currency conversion. A few travellers note that these machines may default to charging you in your home currency rather than GBP, quietly baking in another bad rate. If you must withdraw here, hit “charge in local currency” every time. Regulars say they walk straight past the desks, use fee-free or low-fee cards, and pull cash from destination ATMs instead.
Tip: Treat Travelex at STN as a true emergency-only option and cap yourself to £20–£40 worth of cash; sort the rest online or at an ATM once you land.
