Buying US Dollars in the UK: Today's Best Rate and Where to Get It

Heading to the States? You'll need dollars, and the gap between the best UK provider and the worst can easily be £20 to £40 on a typical holiday spend, more if you accidentally end up at an airport bureau.

This is your complete guide to buying US dollars in the UK. We compare every UK provider in real time so you can see today's best rate at a glance, plus the practical answers most travel-money pages skip: how much to take, which loyalty schemes genuinely boost your rate, where USD actually works outside America (it's more places than you'd think), and what to do with whatever you bring home.

Start with today's live rates below, refreshed hourly across all 10 UK providers we track. Or use the on-this-page menu to jump straight to a section.

💱Today's GBP → USD rates (live, tiered by spend)

Today's rate is 1.3287 USD per £1 at mid-market, refreshed at 14:23 today from the Bank of England reference. What you actually get depends on who you buy from and how much you're buying.

The bigger the order, the better the rate. That's true across the market — every provider works this way, because the per-pound overhead drops as the order size grows.

Online rate vs high-street rate

Online travel-money providers consistently beat high-street counters by 1–2%, sometimes more on small amounts. Lower overheads, smaller markup. Travelex's USA page hedges this with "Online rates vary from in-store"; we'll just show you both side by side and let you decide.

For a £500 order, the typical online-vs-high-street gap is about £8 in your favour. Worth it for the click.

How rates work: mid-market vs retail markup

The mid-market rate is what banks charge each other to swap currency — the wholesale price. Today that's 1.3358. When you buy from any travel-money provider, they add a markup on top. That markup is how they make their money.

Here's how the markups stack up today, roughly:

• Online specialists: 0.3–0.6% over mid-market
• Supermarkets: 0.8–1.5%
• Post Office, Travelex high-street: 1.5–2.5%
• Banks (HSBC, Barclays etc.): 2–4%
• Airport bureaux: 8–12% (avoid)

The maths is simple: a £500 trade at a 0.4% markup gets you about $665. The same £500 at airport rates gets you about $590. Same money, $75 difference.

🏆Best place to buy US dollars (provider comparison)

There's no single best place to buy US dollars — it depends on how much you're buying, when you need it, and whether you've got a loyalty scheme that boosts your rate. Below: today's rates across every UK provider we track, refreshed hourly. We send you to whoever's winning right now.

Online travel-money specialists

Online specialists (Wise, Currensea) typically lead on rate because they don't carry the cost of physical branches. The trade-off is planning: most need 1–2 days to deliver cash, so they're not for last-minute travellers. Minimums vary — some start at £100, some at £300.

Supermarkets — Tesco, Sainsbury's, Asda, Morrisons

UK supermarkets have quietly become serious competitors in travel money. Tesco Bank, Asda Money, Sainsbury's Bank, M&S Bank all sell foreign currency in-store and online. Rates are usually close to high-street travel-money specialists but with one big lever: loyalty schemes (more on those below).

Post Office and Travelex (high-street)

The Post Office has about 11,500 branches, so for sheer reach nothing comes close. Travelex has fewer branches but a strong airport presence. Neither typically wins on rate — but if you need cash the same day, walk-in availability beats a 2% rate advantage.

Banks (HSBC, Barclays, NatWest, Lloyds, RBS)

Most high-street banks sell travel money to existing customers, often with delivery to your branch. Rates are usually the weakest in the category — banks treat travel money as a convenience product, not a profit centre. Worth checking if you already bank with them; not worth opening an account for.

Airport bureaux de change — why to avoid them

Universal worst rates, every time. If you exchange £500 at Heathrow vs ordering the same amount online ahead of your flight, you typically lose £25–40 on a $700 trade. The exception: you've genuinely forgotten cash and you'd rather pay a premium than land without dollars. Even then, take the absolute minimum and use cards once you're there.

Do supermarket loyalty schemes get you a better rate?

Yes — and the maths matters more than people realise. Tesco Clubcard, Asda Rewards, and Sainsbury's Nectar all offer preferential travel-money rates to scheme members. The exact rate boost varies by provider and changes from time to time, so check today's like-for-like comparison above. As a rough guide:

• Tesco Clubcard members get a discount on Tesco's standard travel-money rate when buying through Tesco Bank. At £500 spend with Clubcard, the rate is often competitive with online specialists.
• Asda Rewards members access Asda Money's Preferential Pricing, with a similar mechanism — Rewards-tier rates that beat Asda's standard counter rate.
• Nectar at Sainsbury's — a smaller effect than Tesco or Asda, but still worth checking if you're already a Nectar collector.

For amounts above about £1,000, online specialists usually beat all three even with loyalty boosts. For smaller orders (£100–500) where you can collect from a local store, the loyalty schemes can come out ahead. Today's comparison above shows the actual numbers — no need to guess.

📦How to buy USD (online, click & collect, in-store)

Three ways to buy, each suiting a different timeline. Pick the one that fits.

Buying online — best rates, longer planning window

Online wins on rate (typically 1–2% better than counter) but needs lead time. Most online specialists deliver next working day with Royal Mail Special Delivery; remote areas can take 2–3 days. Free home delivery usually kicks in above £500; under that you'll pay £4–6 for postage. Best for travellers who've booked the trip 7+ days out and don't mind being home for the signature.

Click & collect — best of both, lock the rate

Order online (lock today's rate), collect in-branch when it's convenient. Post Office offers 2-hour click & collect for USD specifically at participating branches — order by 2pm, pick up the same afternoon. Travelex has 17+ store locations plus airport collection. Best for travellers who want the online rate but need cash in hand within 24 hours.

In-store / branch — same-day, walk-in

Walk in, buy on the spot. USD is one of the most-stocked currencies, so most branches that sell travel money will have dollars. Bring photo ID (passport or driving licence) plus proof of address (utility bill or bank statement dated within 90 days) — that's a regulatory requirement, not a provider quirk. Best for last-minute travellers; you'll pay a small premium for the convenience.

💳USD cash + travel money card — choose the right mix for your trip

Most travellers use both cash and a travel money card. Here's when each makes sense — we're not selling you a card; we'll tell you when one helps and when cash alone is fine.

When cash makes sense

Tipping is the big one. American tipping culture expects cash in a way the UK doesn't — housekeeping ($2–5/night left daily), small-vendor tips ($1–2 per drink at a bar), valets, doormen, tour guides. Cash is also king for food trucks, festivals, rural diners, and the small-town businesses that don't always accept cards. Plus a safety reserve if your card has issues. Take a mix of denominations — $1s and $5s are gold for tipping; $10s and $20s for everyday spend. Avoid $50s and $100s, which some smaller US businesses refuse.

When a travel money card makes sense

Larger purchases (hotels, car rentals, tickets) and security (capped balance, freeze from app if lost). Loading USD onto a prepaid card locks today's exchange rate, so you don't sweat rate movement between booking and travel. Look for cards with no fees on spend, no ATM withdrawal fees, mobile-app management, and multi-currency support if you'll travel beyond the US. We don't sell our own card, so we'd point you to MoneySavingExpert's travel-card comparison or search "best travel money cards UK" to find one that fits.

The blend most travellers use

For a 7-day urban trip (NYC, LA, Vegas, Miami), think $300–500 in cash + the rest on card. For a 14-day road trip or rural travel, lean more cash — $700–1,000. For all-inclusive resort stays, less cash is needed because most spend is pre-paid. The mental model that holds up: cash for tips, taxis, and little treats; card for hotels, restaurants, and anything over $50.

🕐Is now a good time to buy US dollars?

Honest answer: nobody can time the market perfectly. What we can do is show you where today's rate sits versus the last 12 months, what's moving it, and how to spread your timing risk if you've got the budget to.

GBP/USD historical rate (12-month chart)

Today's rate of 1.3287 is about [2%] above the 12-month average of 1.3015 — meaning your pound is going further than usual right now. Whether that holds depends on what the next month brings, which nobody knows.

What moves the GBP/USD rate

Plain English on the big movers:

• Fed rate decisions — when the US Federal Reserve raises interest rates, the dollar usually strengthens (you get fewer dollars per pound). When it cuts, dollar weakens.
• Bank of England rate decisions — the mirror effect. Higher UK rates = stronger pound = more dollars per pound.
• US economic data surprises — strong jobs reports or hot inflation data strengthens the dollar.
• Political and risk events — election years, geopolitical tension, fiscal-cliff moments. The dollar tends to strengthen when global markets get nervous (the "flight to safety" effect).

Splitting your purchase to average the rate

If you've got 2–3 months before your trip and a decent-sized order, splitting it into two or three tranches removes some of the timing risk. Buy a third now, a third next month, a third a week before the trip. You'll average across three rates rather than betting on one moment. Works well for trips over £1,000; below that the admin isn't worth it.

Outlook for the dollar — what economists are currently saying

Forecasts change month by month and analysts disagree. The IMF's latest World Economic Outlook expects the dollar to soften modestly against major currencies over the next 12 months as Fed rate cuts come through. Major-bank consensus forecasts for GBP/USD year-end have ranged between 1.28 and 1.40 in recent quarters. Treat all of this as scenario-planning, not prediction — even the people whose job is forecasting get it wrong half the time.

Locking today's rate

If you'd rather not risk waiting, you can lock today's rate today by:

• Buying physical USD now and holding for the trip
• Loading USD onto a prepaid travel money card now
• Setting a rate alert (free) and being notified if GBP/USD hits your target

So — buy now or wait?

For most travellers: buy when you commit to the trip, not when you're hoping for a better rate. Decision-paralysis costs more time than rate-watching saves money. Even a generous 2% rate improvement on £1,000 = £20; the average rate-watcher spends 3+ hours over weeks chasing that £20. If you're going, get on with it. If you've got a flexible timeline and a big order (£2,000+), splitting the purchase across a couple of months is the sensible middle ground.

⚙️How much USD should I take?

Depends on where you're going, how long, and your travel style. Average US daily costs vary enormously by region — a day in NYC isn't a day in rural Tennessee.

Average daily costs in the USA by region

Rough mid-range daily budgets (one person, mid-range hotel, mix of cooking and eating out, mid-tier activities):

• East coast cities (NYC, Boston, DC, Miami): $200–300/day
• West coast (LA, San Francisco, Seattle): $200–300/day
• Texas + Florida (outside Miami): $130–180/day
• Mountain / South / Midwest (Denver, Nashville, Memphis, Minneapolis): $80–130/day
• National parks (Yellowstone, Grand Canyon, Yosemite): $50–100/day if you're camping and self-catering; $200+/day if you're staying in lodges

The Nasdaq "real value of $100" data is a useful sanity-check: $100 in Arkansas has the buying power of about $113, but in California it's only $87. East-coast and west-coast cities feel expensive because they actually are.

Tipping in the USA — what's expected and where

US tipping is genuinely confusing for Brits. Here's a cheat sheet:

Service	Tip
Restaurants (sit-down)	18–22%
Bartenders	$1–2 per drink, or 20% per round
Coffee shop counter	Optional, $1 if friendly service
Hotel housekeeping	$2–5 per night, left daily
Taxi / Uber	15–20%
Hairdresser / spa	15–20%
Tour guides	$5–10 per person per half-day
Doormen, valets	$1–5 per service

The numbers are above UK norms because in many US service jobs the tip is the wage. Skipping it isn't perceived as protest — it's perceived as rudeness. Build it into your daily budget rather than treating it as extra.

How much cash vs. card for a typical trip

A few worked scenarios for a single traveller:

• 7-day NYC trip, mid-range: $300–500 cash + $1,500–2,000 on card
• 14-day road trip (rural US): $700–1,000 cash + $2,500 on card
• 5-day Vegas or Florida resort: $200–400 cash + $1,500–2,500 on card (most spend pre-paid)
• 2-week national parks tour: $400–800 cash + $1,500–2,500 on card

These are starting points, not gospel. Double them for couples, scale them for budget travellers, and add 20–30% if you're a generous tipper or planning to eat out twice a day.

🌍Countries that accept US Dollars

USD is the world's most-traded currency and accepted in far more places than just the United States.

Official USD countries (USA + territories)

The US dollar is the official currency of:

• United States of America (continental + DC)
• Puerto Rico, US Virgin Islands, Guam, American Samoa, Northern Mariana Islands
• Ecuador (since 2000), El Salvador (since 2001) — both ditched their own currencies
• Marshall Islands, Federated States of Micronesia, Palau — small Pacific nations that use USD as official tender

Widely accepted unofficially

Plenty of countries accept dollars as a parallel currency even though they have their own:

• Caribbean: Bahamas (BSD pegged 1:1 to USD), Barbados (BBD pegged), Bermuda (BMD pegged), Turks & Caicos (officially USD), Cayman Islands (KYD pegged), British Virgin Islands (officially USD). Tourist areas almost universally take USD.
• Latin America: Panama (Balboa pegged + USD legal tender), parts of Honduras, parts of Costa Rica
• Southeast Asia: Cambodia (Riel + USD parallel, especially in tourist areas), parts of Vietnam
• Africa: Zimbabwe (multi-currency including USD), Liberia (USD alongside Liberian dollar)

Different-dollar warning — not every "dollar" is USD

This catches Brits out a lot. Several countries have a currency called "dollar" but it's not US dollar:

• CAD — Canadian Dollar — link to /buying/canadian-dollars
• AUD — Australian Dollar — link to /buying/australian-dollars
• NZD — New Zealand Dollar
• HKD — Hong Kong Dollar (USD-pegged but spendable only in Hong Kong)
• SGD — Singapore Dollar
• TWD — Taiwan Dollar
• Caribbean dollars — Bahamas/Barbados/Bermuda each have their own, usually USD-pegged

If your trip mixes USD-using countries with one of the look-alikes, plan accordingly. Showing up to Toronto with American dollars is awkward.

🔁Leftover USD when you return

Came home with leftover dollars? Three options. Here's the maths on each.

Selling unused currency back

Bring leftover notes home and most UK travel-money providers will buy them back. The buy-back rate sits alongside the buy rate at the top of this page — the comparison routes you to whichever provider is offering the best sell-back rate today.

A few rules apply industry-wide:

• Notes only. Coins aren't accepted by any UK provider — the logistics don't work.
• £500 cap per transaction at most providers. Larger amounts need to be split or sent through a bureau in person.
• Buy-back promises. Many providers waive the fee if you bought from them within a set window (typically 28-90 days) — worth checking the provider you bought from first.
• Spreads between the buy rate and sell rate are typically 1–4% for stable currencies, wider for volatile ones.

Keep for next trip vs. sell back

Quick decision framework:

• Keep if you'll travel to a USD country within 12–18 months. Skip the buy-sell spread loss; spend the dollars next trip at the same value.
• Sell back if no USD trip likely. Recovering ~95% of the value beats holding £0 of utility forever.
• Notes never expire — US Treasury policy. Even very old notes are technically legal tender, though some businesses get cautious about pre-1996 "small head" $100 notes. Standard modern notes are fine indefinitely.

What to do with US dollar coins

Coins are universally not accepted for buy-back (every provider in the UK — the logistics don't work). Three options:

• Airport donation — most major UK airports have UNICEF "Change for Good" currency bins for unwanted foreign coins
• Souvenir keepers — state quarters are surprisingly collectible
• Spend on the next trip — coins keep their value forever; just throw them in the next holiday wallet

❓Frequently asked questions

Top questions UK travellers ask about buying US dollars.

What's the best place to buy US dollars in the UK?

Honest answer: it depends on the amount, your timing, and whether you've got a supermarket loyalty card. For larger online orders (£500+) ordered a few days ahead, online specialists usually beat everyone. For small same-day cash, the Post Office's branch network is hard to argue with despite the slightly worse rate. For £200–500 with a Tesco Clubcard or Asda Rewards card, the supermarket loyalty rates often win. The comparison table at the top of this page shows today's actual rates across every UK provider — so you can see who wins right now.

Is it cheaper to buy US dollars in the UK or in the US?

UK in most cases. US ATMs typically charge $2.50–$3 per withdrawal on top of your bank's foreign-transaction fee, which often runs another 2–3% per transaction. For typical holiday-sized amounts, buying ahead in the UK at a competitive rate beats US ATM withdrawals on price. The exception: large amounts (£5,000+) where a US-based bank wire might come out cheaper — but that's not a typical holidaymaker scenario.

Do Tesco Clubcard holders get a better US dollar exchange rate?

Yes — Tesco Bank's travel money service offers Clubcard members a preferential rate that's typically better than its standard counter rate. The exact rate boost changes from time to time, so check the live comparison at the top of this page for today's actual Clubcard rate vs others. Parallel loyalty schemes exist at Asda (Asda Rewards Preferential Pricing) and Sainsbury's (Nectar). For amounts above £1,000, online specialists usually still win even with loyalty rates; below that, supermarket loyalty can come out ahead.

What is the buying rate of US dollars today?

Today's mid-market rate is 1.3358 USD per £1 (BoE reference, refreshed at 14:23 today). See the tiered rate table at the top of the page for rates at other spend amounts, and the provider comparison for what every other UK provider is offering right now.

Is now a good time to buy US dollars?

Nobody can time the market perfectly. Today's rate of 1.3287 is about 2% above the 12-month average, so your pound is currently going further than usual. Whether that holds depends on what comes next, which nobody knows. For most travellers the practical answer is: buy when you commit to the trip, not when you're hoping for a better rate. If you've got a big order and a flexible timeline (over £2,000, more than two months out), splitting the purchase across a couple of months is the sensible middle ground.

Can I buy US dollars with a credit card?

Yes, but most credit card issuers treat travel-money purchases as cash advances, which usually means a cash-advance fee (typically 3% of the amount) and interest charged from day one (typically 25–35% APR, no interest-free period). A debit card or bank transfer is almost always cheaper. If you only have a credit card, check your issuer's terms first — a few cards do treat travel money as a normal purchase.

Will US dollars work in Canada, Mexico, or the Caribbean?

Mixed answer. Caribbean: USD is widely accepted in resort areas — often as the de facto currency, sometimes officially. Bahamas, Bermuda, Turks & Caicos, BVI all take USD without issue. Mexico: USD is accepted in border towns and major tourist areas at a noticeable markup; further inland, pesos are essential. Canada: not reliably — some border-town businesses and high-tourist spots will take USD but you'll get a poor exchange. For a Canadian trip, get Canadian dollars. Always carry the local currency for primary destinations; USD as a backup is fine.

What do I do with leftover US dollar notes when I return?

Three options: sell back to a UK travel-money provider (recover ~95% of the value), keep for the next trip (USD notes don't expire, so no rush), or use online with US-based merchants if you've got a PayPal or similar account that handles USD. See the Leftover USD when you return section for the buy-back terms of whichever provider is winning today.

How long do US dollar notes stay valid?

Indefinitely. US Treasury policy: all genuine US currency ever issued remains legal tender, with no expiry date. The practical caveat: pre-1996 "small head" $100 notes occasionally get refused outside the US because they're easier to forge and many cashiers haven't seen one. Standard post-2013 notes (with the bigger portraits and blue ribbon on the $100) are accepted everywhere. If you've got pre-1996 notes, swap them at a bank before travelling.
