British visitors to the United States face one of the biggest healthcare cost shocks in the world. At home, the NHS provides free care at the point of use. In America, there is no equivalent — every doctor visit, hospital admission, and ambulance ride carries a price tag. This guide explains why travel insurance for UK visitors to the USA is non-negotiable, and which plans provide the best coverage in 2026.
Quick Answer
UK visitors to the USA need dedicated US visitor insurance — the NHS provides zero coverage abroad. A single US emergency room visit can cost $5,000–$20,000; a hospitalization can run $100,000+. Look for plans with at least $100,000 in medical benefits. IMG Patriot America Plus and Trawick Safe Travels USA are the top picks for British travelers.
Why the NHS Doesn't Help in the USA
The National Health Service is funded by UK taxpayers and operates within UK borders only. The UK has reciprocal healthcare agreements with several countries — but the United States is not one of them. When a British citizen walks into a US hospital, they are treated as a private, uninsured patient and billed accordingly.
A common scenario: a 70-year-old British parent visiting their child in California experiences a heart attack. Emergency cardiology, a 4-day ICU stay, and follow-up care could total $150,000–$300,000. Without proper visitor insurance, the family pays every penny.
Even for younger visitors, a broken leg requiring surgery can cost $30,000–$80,000. A severe allergic reaction treated in an ER typically runs $5,000–$15,000. Standard travel insurance sold in the UK often excludes US coverage or caps it far below what US care actually costs.
What to Look for in a Plan for UK Visitors
- US-specific medical coverage: Many UK travel insurance products either exclude the USA or provide inadequate limits. Dedicated US visitor insurance is specifically designed for the American healthcare market.
- Pre-existing condition coverage: Heart disease, arthritis, diabetes, and respiratory conditions are common among older British visitors. Look for plans covering acute onset of pre-existing conditions.
- High coverage limits: Minimum $100,000 — $500,000+ is recommended for visitors over 60. US critical care is among the most expensive in the world.
- Emergency medical evacuation: If your parents need to be repatriated to the UK for ongoing care, evacuation coverage handles the cost. Look for at least $500,000.
- Trip duration: ESTA allows 90-day stays; B-2 visas allow up to 6 months. Make sure the policy covers the full trip.

ESTA vs B-2 Visa: Does It Affect Insurance?
Whether your family member travels on ESTA (90-day Visa Waiver) or a B-2 visitor visa (up to 6 months), the insurance need is identical. Neither entry type comes with any healthcare benefit. The only difference is trip length — make sure your policy matches the full duration of the stay.
For extended visits, some families purchase a 6-month policy upfront; others start with a 90-day policy and extend it. Most plans allow extensions as long as no claims have been filed.
Buy Before They Depart
Insurance must be purchased before your family member arrives in the USA. Coverage cannot start retroactively. Any medical event that occurs before the policy effective date will not be covered.
Frequently Asked Questions
Does travel insurance cover COVID-19 for UK visitors to the USA?
Many current plans treat COVID-19 like any other covered illness. Check the specific plan's certificate for any exclusions before purchasing.
Can UK visitors use any hospital in the USA?
Yes. Most visitor insurance plans are PPO-based, meaning you can visit any licensed US physician or hospital. In-network providers may have lower out-of-pocket costs, but out-of-network care is typically covered as well.
Can I extend the policy if I stay longer than planned?
Yes — most plans allow extensions before the current policy expires and before any claim is filed. Contact Tower Hill at support@towerhillcorp.com or call (832) 856-1704.
Is UK travel insurance from comparison sites enough for the USA?
Usually not. UK travel insurance policies frequently exclude the USA, cap US coverage at low limits (e.g., £500,000 which sounds like a lot but doesn't go far in US healthcare), or require you to pay upfront and claim back. Dedicated US visitor insurance pays US providers directly and is designed for the American system.
