The cheapest way to get foreign currency for a trip through Heathrow is almost never the airport bureau de change on the day you fly. The best-value route, in order, is usually: use a fee-free travel debit or credit card for spending and cash withdrawals abroad, top that up with a small amount of cash ordered online in advance for click & collect at Heathrow, and treat the airport counters as a last-resort, emergency-only option because their rates are consistently among the worst on the high street.
Why airport bureaux de change are usually the worst option
Airport currency desks know that a share of their customers are buying at the last minute, with no easy way to shop around once they are airside. That convenience comes at a price. Consumer sites including comparetravelcash.co.uk and thetravelmagazine.net report that walk-up airport rates are typically around 10–15% worse than the mid-market (interbank) exchange rate, and Which? has documented individual cases of travellers being charged well over the odds at airport currency counters and cash machines. Treat any single figure as illustrative rather than a promise — the practical takeaway is the same: compare live rates before you travel, and don't assume the desk at the airport is offering a fair deal simply because it's convenient.
Order online and collect at Heathrow (click & collect)
The better way to get cash at the airport, if you want notes in hand before you fly, is to order online in advance and collect at Heathrow rather than buying over the counter on the day. Ordering ahead typically locks in a rate that's noticeably better than the airport's walk-up rate, and many providers also waive collection fees for pre-orders.
Heathrow's on-site currency exchange provider changed in early 2026: Global Exchange took over as Heathrow's official currency services partner across all four terminals (T2, T3, T4 and T5) from January 2026, replacing the long-standing Travelex concession. Global Exchange's Heathrow service includes staffed bureaux at check-in and airside locations in each terminal, self-service and cash-to-cash ATMs, and an online click & collect option where you order currency in advance and pick it up at the airport. Other independent operators, such as No1 Currency, also offer click & collect services for Heathrow passengers. Because providers and locations can change, check current terminal-by-terminal counter locations and opening hours (broadly around 05:00–22:00) on the operator's own site shortly before you travel, and compare their pre-order rate against other online providers rather than assuming it's automatically the cheapest.
Typical click & collect steps:
- Compare rates across two or three currency providers online before ordering
- Place your order and pay in advance, specifying the currency and amount
- Choose a Heathrow collection point (or ATM click & collect, where offered) and a collection window
- Collect the cash airside or landside using your order confirmation, ID and payment card, depending on the provider's process
Fee-free travel cards: usually the cheapest way to spend abroad
For day-to-day spending and ATM withdrawals overseas, a fee-free travel debit or credit card is generally the cheapest option of all, cheaper than carrying a wallet full of pre-ordered cash for anything beyond incidental spending money. According to Which? and MoneySavingExpert's travel card comparisons, UK current accounts and dedicated travel cards such as Starling and Monzo are commonly cited as charging no foreign transaction fees on card purchases abroad, using close-to-mid-market exchange rates. Policies on cash machine withdrawals differ between providers, some cap fee-free withdrawals or charge for larger amounts, so check the current terms of your own bank or card before you travel, since providers change their fee structures from time to time.
The practical strategy most consumer money sites converge on is a combination:
- Spend on a fee-free card for the bulk of your holiday spending and cash machine withdrawals abroad
- Carry a modest amount of local cash for the moment you land, taxis, tips, or places that don't take cards, ordered online in advance rather than bought at the airport counter
- Avoid airport bureaux de change for anything beyond a genuine last-minute emergency, since they are reliably the most expensive way to buy currency
Getting to the terminal to collect your order
If you're flying from Heathrow and collecting a click & collect order airside, build in a little extra time to clear security first. Check our terminal guide and FAQs for what to expect at each terminal, and see our public transport page for the quickest way in if you're not driving. Drivers dropping off or collecting currency landside before travelling should check current parking options, since short-stay parking is usually the most convenient choice for a quick errand rather than long-stay or Park & Ride. If you're bringing cash back into the UK or carrying a large amount out, it's also worth checking the UK customs allowances for Heathrow, since cash declaration rules apply above certain thresholds.
FAQs
Is it cheaper to exchange currency at Heathrow Airport than at home?
Generally no. Airport bureaux de change, including those at Heathrow, typically offer worse rates than ordering online in advance or using a fee-free card abroad, because they price in the convenience of last-minute, no-alternative buyers. Compare live rates before you travel rather than assuming the airport is competitive.
Who currently runs the currency exchange desks at Heathrow?
Global Exchange became Heathrow's currency exchange partner across all four terminals from January 2026, replacing the previous long-term provider, Travelex. Always check the operator's own site close to your travel date, as concessions and locations can change.
What is click & collect currency and is it worth using at Heathrow?
Click & collect lets you order foreign currency online in advance at a locked-in rate, then pick it up at a Heathrow counter or dedicated ATM rather than buying on the day. It's usually worth it if you want cash in hand for arrival, since pre-order rates are typically better than walk-up airport rates and collection is often free.
Which terminals at Heathrow have currency exchange desks?
All four terminals, T2, T3, T4 and T5, have currency exchange counters, typically located in the check-in concourse and again after security in departures, with further desks in arrivals. Exact counter numbers and opening hours vary by terminal and are best checked with the current operator shortly before travel.
Do I need cash at all if I have a fee-free travel card?
Not always, but it's sensible to carry a small amount of local cash for the moment you land, tips, or vendors that don't accept cards. For everything else, a fee-free debit or credit card that doesn't charge for foreign purchases or ATM withdrawals is usually the cheapest way to spend abroad.
Can I exchange leftover foreign currency back at Heathrow when I return?
Most currency exchange operators at Heathrow, including desks in arrivals, will buy back unused foreign notes, though rates for buying back currency are generally worse than the rate you paid, and some currencies or coins may not be accepted at all. It's usually better to spend down cash before returning or exchange it with your bank or online provider instead.
