You’ve booked the flights. The Virgin Atlantic or BA seats are secured, and you’re already dreaming about that first authentic burger in NYC or the humid, salty air of the Florida Keys. But then there's the boring bit. The bit everyone puts off until they’re sitting in the Gatwick departures lounge. Buying travel insurance UK to US isn't just a tick-box exercise like it is when you’re heading to Spain or France. It’s actually the most critical part of your prep. Seriously.
The US healthcare system is basically a different planet. There is no reciprocal agreement. Your GHIC or EHIC card is a useless piece of plastic once you cross the Atlantic. If you trip on a cracked sidewalk in Chicago or get a nasty bout of food poisoning in Vegas, the bill won't just be high—it will be life-altering. We are talking thousands of dollars for a simple X-ray and tens of thousands for an overnight stay.
I’ve seen people assume their bank’s "free" insurance covers them. Sometimes it does. Often, it doesn't cover the specific, eye-watering liability limits needed for the States. You need to know exactly what you’re paying for before you hit the Tarmac at JFK.
Why America is the "Special Case" in Your Policy
When you go to buy a policy, you’ll notice a very specific filter: "Worldwide excluding USA, Canada, and the Caribbean" or "Worldwide including USA." The price jump is usually significant. This isn't the insurance companies being greedy; it's a direct reflection of the cost of American medicine.
In the UK, we're used to the NHS. In much of Europe, costs are regulated. In the US, a single day in a California hospital can easily exceed $10,000. According to the International Federation of Health Plans, the average cost of an inpatient day in the US is remarkably higher than anywhere else on earth. If you need an air ambulance back to Heathrow? You’re looking at a £50,000 to £100,000 bill.
Your travel insurance UK to US needs a medical cover limit of at least £2 million, though most decent UK insurers like Aviva, Post Office, or Staysure now offer £5 million to £10 million as standard. It sounds like an insane amount of money, but in the context of American surgical fees and specialized repatriation, it’s actually just "adequate."

Don't skimp. Truly. Saving £20 on a premium by choosing a lower medical limit is the definition of "penny wise, pound foolish."
The "Hidden" Exclusions That Trip Up Brits
Most people think insurance is just for "big" things like plane crashes or heart attacks. But the reality of travel insurance UK to US is often found in the fine print regarding pre-existing conditions and alcohol.
Honesty is everything. If you have high blood pressure and you don't tell your insurer because "it's controlled by meds," you are effectively uninsured. If you have a flare-up in San Francisco, the insurer will check your medical records. If they find an undeclared condition, they will reject the claim. Period. You’ll be left holding a $40,000 bill.
Then there’s the "alcohol clause." We Brits love a drink on holiday. But nearly every UK travel policy has a clause that voids medical claims if you were "under the influence." The definition is often vague. If you fall down some stairs after three beers in a Nashville honky-tonk, the insurer might argue your "loss of faculties" led to the injury. It’s a harsh reality that catches out dozens of holidaymakers every year.
Cancellation and the "Shoulder" Costs
It isn't just about the doctor visits. What if your airline goes bust? What if a family member gets sick two days before you fly?

- Trip Cancellation: Make sure your cover matches the total cost of your trip (hotels, flights, car hire).
- Missed Connection: Crucial if you’re flying via Dublin or Reykjavik.
- Baggage: Check the "single item limit." If you’re carrying a £1,500 MacBook but your policy only covers £250 per item, you’re losing out.
Liability: The Part Nobody Reads
Americans love a lawsuit. That’s a bit of a stereotype, but legally, it holds water. Personal liability cover is a massive component of travel insurance UK to US.
Imagine you’re skiing in Aspen and you accidentally collide with someone. Or you’re cycling in Central Park and hit a pedestrian. In the UK, we might swap details and apologize. In the US, you could be sued for medical expenses, loss of earnings, and "pain and suffering."
Your policy should ideally have £1 million to £2 million in personal liability. This covers your legal fees and any settlements. Without it, a momentary lapse in concentration on a rental bike could bankrupt you.
Crucial Tips for Choosing Your Provider
Don't just go to a comparison site and click the cheapest one. Look at the "Excess." That’s the amount you pay toward a claim. A £0 excess policy is more expensive upfront but saves you a headache later.
- Check the 24/7 Assistance Line: Ensure they have a dedicated US-based team or a global team that understands how to issue "guarantees of payment" to American hospitals. Some hospitals won't even treat you beyond stabilization unless they have proof of insurance.
- Activity Cover: Planning to drive a Mustang? Riding a horse in Texas? Check if those specific activities are covered. Often, "extreme" sports—which can include things as simple as jet-skiing—require an extra premium.
- Duration Matters: If you’re doing a 3-month road trip across Route 66, a standard "single trip" policy might have a 31-day limit. Read the "max trip duration" carefully.
Realities of the Claim Process
If something goes wrong, you can't just wait until you get home to deal with it. You must call your insurer's emergency assistance number immediately. They act as the intermediary between you and the hospital's billing department.

Keep every single receipt. Every Uber to the pharmacy, every bottle of water bought while waiting for a prescription, and every medical report. The paper trail is your best friend. UK insurers are notoriously pedantic about documentation. If you don't have the "Proof of Loss" or the official medical coding (called ICD-10 codes in the US), your claim might be delayed for months.
Actionable Steps Before You Fly
First, check your existing cover. Look at your bank account benefits and your home insurance. Sometimes they have "hidden" travel perks, but check if they exclude the USA. They often do.
Second, use a specialist broker if you have complex medical needs. Companies like AllClear or Staysure specialize in "difficult" cases that big-name banks won't touch.
Third, buy your insurance the second you book your flights. If you wait until the day before you fly, you aren't covered for anything that happens in the meantime. If your hotel burns down or you lose your job three weeks before the trip, only an active policy can help you get your money back.
Finally, download the insurer’s app or save their emergency number in your phone as "INSURANCE EMERGENCY." You don't want to be scrambling through emails while standing in an ER in New Orleans.
Check the FCDO (Foreign, Commonwealth & Development Office) website for the latest travel advice to the US. It’s the gold standard for knowing what’s happening on the ground. Once the paperwork is sorted, go enjoy that road trip. The peace of mind is worth every penny of the premium.
