Best travel insurance from UK to USA – complete guide (2026)

If you're planning a trip to America, sorting out travel insurance from UK to USA should be the first thing on your list, before you book hotels, before you plan excursions, before anything. The reason is simple: the USA has the most expensive healthcare system in the world, and it has no reciprocal health agreement with the UK. Your NHS card does nothing there. A single night in an American hospital can cost more than your entire holiday budget.

This guide covers what you need to know to choose the right policy, what American healthcare actually costs tourists, and which UK insurers are worth considering for a US trip.

Do you need travel insurance for USA?

Travel insurance is not legally required to enter the USA on a tourist visa or under the Visa Waiver Program (ESTA). But the financial risk of going without it is genuinely alarming.

A broken leg requiring surgery and a 3-day hospital stay in New York can cost between $50,000 and $100,000. An air ambulance from a US hospital back to the UK can cost $80,000 to $150,000 on its own. These aren't edge cases. They happen to tourists every year, and without insurance, that bill lands directly on you.

Beyond medical emergencies, insurance also covers you if your flight gets cancelled, your luggage goes missing, or you need to cut your trip short because of a family emergency at home. For a 2-week US trip, a solid single-trip policy typically costs between £40 and £100 depending on your age and the level of cover. The maths isn't complicated.

What should USA travel insurance cover?

Emergency medical coverage

This is the non-negotiable one. For a US trip, you want at least £2 million in emergency medical cover. Many policies go up to £5 million or even £10 million for the USA specifically, because American hospitals bill at a scale that makes European healthcare costs look modest.

Check whether the policy covers emergency evacuation and repatriation. If you're seriously ill or injured in, say, rural Montana, getting airlifted to a major hospital and eventually back to the UK is where costs spiral fastest.

Trip cancellation

Good policies cover trip cancellation up to the full cost of your holiday if you have to cancel before departure because of illness, bereavement, redundancy, or other specified reasons. Check the exact list of covered reasons, as some budget policies have a very short list.

Lost luggage

Most policies cover lost, stolen, or damaged baggage up to a set limit, typically £1,500 to £3,000. Individual item limits often apply, so if you're travelling with expensive camera equipment or jewellery, check those sub-limits carefully.

Flight delays

Many policies pay a fixed amount (usually £20 to £50 per 12-hour delay period) if your flight is delayed beyond a certain threshold, typically 4 to 6 hours. It's a minor benefit compared to medical cover, but useful for long-haul delays.

Personal liability

Personal liability cover protects you if you accidentally injure someone or damage property and are sued. In the USA, where litigation is far more common than in the UK, this matters. Look for at least £1 million in personal liability cover.

Best travel insurance companies for USA trips

Allianz

Allianz is one of the most recognised names in travel insurance globally. Their USA-specific policies tend to have high medical limits and strong emergency assistance networks in America. Their claims process is generally reliable, and they have 24/7 emergency lines specifically for medical incidents abroad.

Aviva

Aviva's travel insurance for USA residents is sold as part of their broader international travel range. They're competitive on price for single-trip cover and have solid medical limits. If you already hold other Aviva products, it may be worth getting a quote from them first for any loyalty pricing.

AXA

AXA is a strong option for USA travel health insurance. Their policies typically include good medical evacuation cover and a clear 24-hour helpline. AXA also tend to be clear about what's excluded, which matters a lot more than people realise when it comes time to claim.

Staysure

Staysure is particularly well-regarded for travellers with pre-existing medical conditions. They're willing to cover a wider range of conditions than many standard insurers, which makes them a go-to for older travellers or those with ongoing health issues. Their premiums reflect this, but the access to cover can be worth it.

Coverwise

Coverwise is a comparison and direct insurer that often comes up well on price. They offer solid coverage limits for the USA at competitive rates. Worth getting a quote from them alongside the bigger names, particularly for single-trip cover.

When comparing any of these, use a comparison site like MoneySuperMarket or Compare the Market to see side-by-side quotes, then go directly to the insurer's site to read the policy wording before you buy.

How much does travel insurance cost?

For a healthy adult under 40 taking a 2-week single trip to the USA, expect to pay roughly £40 to £70. Prices go up with age, pre-existing conditions, and the level of cover you choose.

Family policies for 2 adults and 2 children typically run between £80 and £150 for a 2-week US trip.

Factors that push the price up include:

• Age (insurers charge significantly more once you're over 65)
• Pre-existing medical conditions
• Adding adventure sports or extreme activities cover
• High trip cost requiring generous cancellation cover
• Longer trip duration

Annual multi-trip policies are worth looking at if you travel more than twice a year. For regular UK travellers, an annual policy covering worldwide travel (including the USA) often works out cheaper than multiple single-trip policies. Prices for annual policies covering the USA start around £120 to £200 for a single adult.

USA healthcare costs tourists should know

American hospitals are not obliged to provide free emergency care beyond stabilisation. They will treat you in a life-threatening emergency, but the bill that follows is real and immediate.

Some concrete figures to put this in context:

• Emergency room visit (minor injury): $1,000 to $3,000
• Overnight hospital stay: $10,000 to $30,000
• Surgery (broken bone, appendix removal): $20,000 to $80,000
• Ground ambulance: $1,000 to $3,000
• Air ambulance (domestic): $30,000 to $70,000
• Medical repatriation flight to UK: $80,000 to $150,000

These are estimates, and costs vary widely by state and hospital. New York and California tend to be at the higher end. But even the lower end of these figures is enough to wipe out most people's savings entirely.

How to choose the right policy

Start with the medical limit. For the USA, don't accept anything under £2 million. Many good policies offer £5 million to £10 million for American destinations, and there's rarely much difference in price between those tiers.

Read the exclusions carefully. This is where people get caught out. Common exclusions include:

• Pre-existing medical conditions not declared at the time of purchase
• Incidents involving alcohol if deemed a contributing factor
• Adventure sports and activities (skiing, skydiving, hiking above certain altitudes)
• Travel to areas under Foreign Office advisory warnings

If you're planning any adventure activities, check whether they're covered or available as an add-on. Many standard policies exclude activities like white-water rafting, skiing, and even some hiking. Add-on costs are usually modest, around £10 to £30 extra, and well worth it.

Also check the claims process before you buy. Look for an insurer with a 24-hour emergency line that's staffed by actual humans, ideally with staff based in the USA who can liaise with American hospitals directly.

Tips for buying travel insurance

Buy as soon as you book your flights. Policies bought on the day of booking cover you for trip cancellation from that point forward. If you wait until the day before you fly, you've already lost that protection for the entire booking period.

Keep a digital copy of your policy documents saved somewhere you can access offline, like a downloaded PDF on your phone. Don't rely on email access abroad.

Know your policy number and the emergency claims line number before you travel. Write them down separately from your phone. If your phone is stolen or you're in hospital, you need to be able to give that information to medical staff or your travel companions without hunting through an inbox.

Declare all pre-existing conditions honestly. Failure to declare can void the entire policy, not just the claim related to that condition.

Common mistakes travellers make

Buying the cheapest policy available without checking the medical limit is the biggest one. A £25 policy that caps medical cover at £500,000 is genuinely inadequate for USA travel. That sounds like a lot of money until you see what an American hospital charges for a 5-day ICU stay.

Ignoring the trip cancellation terms is another. Some budget policies only cover cancellation if you're hospitalised. If you need to cancel because a close family member is seriously ill, that's covered under most standard policies but not all cheap ones.

Not reading the small print on activities is common. People book a trip to Vegas, end up doing a helicopter tour over the Grand Canyon, and discover after an incident that "aerial activities" were excluded.

Cheapest travel insurance for USA: is it worth it?

Cheap travel insurance for USA from UK comparison sites often looks appealing. A £20 to £30 policy sounds fine until you look at what it actually covers.

Budget policies typically have lower medical limits (sometimes as low as £500,000), higher excesses (meaning you pay the first £200 or £300 of any claim), shorter lists of covered cancellation reasons, and tighter restrictions on pre-existing conditions.

For a trip to Europe where the NHS covers much of your emergency care under reciprocal agreements, a cheap policy might be fine. For the USA, the risk profile is completely different. The gap between a £40 policy and a £70 policy for a US trip is often the difference between £500,000 and £5 million in medical cover. That gap matters.

Why is USA travel insurance so expensive?

UK to USA travel insurance costs more than cover for most other destinations because American healthcare is priced differently from anywhere else in the world. UK insurers are pricing in the real cost of a potential medical claim in America, and that cost is genuinely higher than in Europe, Asia, or most of the rest of the world.

A hospital stay in France might cost an insurer £3,000 to £10,000. The same stay in a US hospital can cost £30,000 to £100,000. Insurers price their premiums to reflect that liability.

Ambulance costs are a separate issue. In the UK, an ambulance is free. In the USA, a standard ground ambulance ride can cost $1,500 to $3,000, and those costs land on the insurer if you're covered or on you if you're not.

People also ask

Is travel insurance mandatory for USA?

No, the USA doesn't require tourists to have travel insurance to enter. But given the cost of American healthcare, travelling without it is a significant financial risk.

How much medical coverage is enough?

At minimum £2 million for USA travel. £5 million is more comfortable, and many UK insurers offer this without a significant price increase.

Which insurance is best for USA travel?

Allianz, AXA, and Staysure are consistently well-reviewed for USA trips. The "best" policy depends on your age, health, and what activities you're planning.

Can I buy insurance after booking flights?

Yes, but buy as soon as possible after booking. Buying on the day of booking means cancellation cover applies from that point. Waiting means you're unprotected for the gap between booking and purchase.

Conclusion

American healthcare costs are the main reason USA travel insurance for UK residents is non-negotiable. The NHS doesn't follow you across the Atlantic, and the financial exposure from even a moderate medical incident in the USA is serious enough to affect people for years.

Buy a policy with at least £2 million in medical cover, read the exclusions before you sign, declare your conditions honestly, and buy it on the same day you book your trip. That's the whole framework. The rest is detail.

If you're planning a broader US itinerary and want help thinking through the trip itself, a USA road trip planning guide is a good next step once your insurance is sorted.
