Is It Better to Exchange Currency Before Travelling or Abroad?

The currency exchange question feels like it should have a simple answer, but “it depends” is doing heavy lifting here. Airport kiosks, high street bureaus, foreign ATMs, prepaid cards, your debit card — the rate you get can vary by 10% or more between the best and worst options, which on a £1,000 holiday spend is £100 either way. I’ve used them all across 30+ countries. Here’s the definitive answer. So is it better to exchange currency before travelling or abroad? The short answer: neither — here’s what actually gets you the best rate.

Better Before Travelling or Abroad? The Short Answer

For most trips: don’t exchange much cash in advance at all. Use a fee-free debit card (Monzo, Starling, Chase) at foreign ATMs and for card payments — you’ll get near the interbank rate, which beats almost every cash exchange option. Take a small amount of local currency for arrival (taxi, first coffee), and get the rest as you go. The days of queuing at a bureau de change with a wad of pounds are over.

Option by Option, Ranked

1. Fee-free debit card abroad (best)

Monzo, Starling, Chase and similar give you the Mastercard/Visa wholesale rate with no markup on card payments and fee-free ATM withdrawals (up to monthly limits — Starling is unlimited, Monzo/Chase have caps). This is within a fraction of a percent of the best rate available to humans. Always pay in local currency when offered a choice — never pounds (dynamic currency conversion adds 3–8%).

2. Foreign ATMs with a good card (excellent)

Same great rate for cash. Watch for: local ATM operator fees (£2–£5 in some countries — try different banks), and always decline the ATM’s conversion offer. See our Turkey cash guide for a worked example.

3. Pre-ordered currency online (good)

Ordering euros/dollars online for collection or delivery (Travelex online, Post Office travel money online) beats walk-in bureau rates by 2–4%. Worth doing for the arrival cash float — £100–£200 in local currency.

4. High street bureaus (mediocre)

Post Office, M&S, Tesco travel money — convenient, rates 3–6% off the interbank. Fine for small amounts; expensive for large ones. Never use them for your main holiday funds.

5. Airport kiosks (bad)

Convenient and terrible — often 8–12% off the real rate. Only for emergencies (“I need taxi money and the ATMs are broken”). If you must, change the minimum.

6. Hotel exchange desks (worst)

Some of the worst rates in existence. Avoid entirely.

7. Your UK bank’s travel money (variable)

Usually poor rates plus fees. The same bank’s fee-free card abroad is excellent; their cash service is not. Funny how that works.

How Much Cash Should You Actually Take?

• Card-friendly destinations (most of Europe, USA, Australia): £50–£100 equivalent for arrival, then ATMs/cards.
• Mixed destinations (Turkey, Morocco, Southeast Asia): £150–£300 equivalent — see our Turkey guide.
• Cash-heavy destinations (Japan’s smaller towns, parts of Africa): more — research your specific destination.

Prepaid Travel Cards: Still Worth It?

Revolut, Wise and similar multi-currency cards let you hold and convert currencies in-app at near-interbank rates — excellent for budgeting (load £500, it’s ring-fenced) and for currencies your bank handles poorly. The catch: weekend markups (0.5–1% on Revolut) and ATM limits. They’re a great second card; I wouldn’t rely on one exclusively.

Traps to Avoid

• “0% commission” signs — the commission is hidden in a terrible rate. Compare the actual rate to the interbank rate on Google, not the commission claim.
• Dynamic currency conversion — “pay in pounds?” abroad. Always no. Always local currency.
• Buying back leftover currency at the airport — the buy-back rate is awful. Spend it, keep it for next time, or donate it.
• Exchanging at home for exotic currencies — rates for less common currencies in the UK are poor; get them at destination ATMs instead.
• Carrying huge cash amounts — loss/theft risk plus most travel insurance caps cash cover at £200–£500.

Currency Exchange for Specific Destinations

USA (dollars)

Dollars are the easiest foreign currency to get in the UK — decent rates from online pre-order, and US ATMs are plentiful. But America is increasingly card-only in cities; take $100–$200 for tips (America’s tipping culture is cash-friendly) and small vendors. Always pay in dollars, never accept “pay in pounds”.

Japan (yen)

Japan is still cash-heavy outside major cities — take more than you think (£300–£400 equivalent). Exchange in Japan (7-Eleven ATMs are the foreign-card gold standard) rather than the UK, where yen rates are poor. IC cards (Suica/Pasmo) for transport can be loaded with foreign cards at airports.

Turkey (lira)

Volatile currency — don’t buy large amounts in advance; the rate moves daily. Fee-free card at Turkish ATMs on arrival is the play. See our Turkey cash guide for the full breakdown.

Eurozone (euros)

The simplest case: pre-order €100–€200 online for arrival, then fee-free cards and ATMs. Euros from UK bureaus have the tightest spreads of any currency — even high-street rates aren’t terrible. But the card is still better.

Exotic currencies

For less common currencies (Vietnamese dong, Moroccan dirham, Egyptian pounds), UK rates are poor and availability is limited. Take US dollars or euros as backup and exchange locally, or just use ATMs on arrival. Research each destination — the gov.uk travel advice pages include money guidance per country.

The Fee-Free Card Stack: What to Carry

The optimal 2026 travel wallet:

• Primary: Chase or Starling debit — fee-free spending and ATM withdrawals, excellent app, instant notifications.
• Backup: a second fee-free card (Monzo) — cards get lost, blocked, or eaten by ATMs. Two is one, one is none.
• Credit card: Halifax Clarity or Barclaycard Rewards for Section 75 protection on purchases over £100 — use for hotels and car hire.
• Prepaid (optional): Revolut/Wise for holding specific currencies or budgeting a fixed holiday pot.

Keep them in different places (one in the hotel safe). Tell no one your PINs, obviously — but do tell your banks you’re travelling (most detect it automatically now, but the notification prevents blocks). And photograph both sides of every card, stored securely — losing your wallet abroad is solvable if you have the numbers.

When Cash Is King (Despite Everything)

The card-first strategy has exceptions:

• Markets and haggling: cash-only, everywhere in the world.
• Tips: many cultures tip in cash; card tips often don’t reach staff.
• Small towns and rural areas: card acceptance drops sharply outside cities in most countries.
• Emergencies: power cuts, network outages, lost cards — cash is the backup that always works.
• Budgeting: some people spend less with physical cash — the “envelope method” works because handing over notes hurts in a way tapping doesn’t.

The 2026 answer to “before or abroad?” is therefore: a little before (the arrival float), the rest abroad via fee-free cards and ATMs. The bureau de change is a legacy industry; your banking app ate it. For trip-specific money planning, see our Portugal spending guide and Turkey cash guide.

The Practical Takeaway

Get a fee-free card (Starling/Monzo/Chase), pre-order £100–£200 of local currency online for arrival, then use ATMs and card payments abroad — always in local currency, always declining conversion offers. Avoid airport kiosks and hotel desks entirely. The best exchange strategy in 2026 isn’t about finding the best bureau; it’s about barely needing one. Your phone’s banking app has replaced the travel money industry — let it. And if your flight’s delayed while you’re sorting all this, our delayed flight compensation guide might literally pay for the holiday.
