A British tourist in Florida fell off a kayak in 2024, hit her head on a submerged rock, and spent eleven days in a Miami hospital with a serious concussion and a broken arm. The bill, before insurance, was $186,000. The same incident in a UK hospital would have produced a bill of roughly £0, because that's how the NHS works. The same incident in Spain would have been mostly covered by the GHIC card with a small co-pay. The same incident in the United States produces a $186,000 bill because that's how American healthcare works.
Travel insurance in the UK is mostly genuinely cheap — £40-£100/year for an annual multi-trip policy that covers an unlimited number of trips. The reason it's so cheap is that most claims are small (lost luggage, delayed flight, a holiday cut short by a relative's illness). The reason it's worth buying anyway is that the rare big claim is so big that no household budget plausibly absorbs it.
What you're actually insuring against
Travel insurance bundles several things into one premium, and they're worth ranking by how much you'd actually miss them:
Medical cover abroad. This is the load-bearing reason for travel insurance. Cover limits are typically £5-£15 million, which sounds excessive until you read the Florida hospital story. For trips to the United States, Canada, or anywhere with private healthcare and no reciprocal arrangement with the UK, this single line is worth more than the entire premium.
Trip cancellation. If you have to cancel before travel — illness, bereavement, a family emergency — the policy pays back the non-refundable cost of the trip. For families with £4,000-£8,000 booked on a once-a-year holiday, this matters more than people anticipate. The policy needs to be in place from booking, not from departure.
Trip interruption / curtailment. If you have to come home mid-trip for a covered reason, the policy reimburses the cost of getting home and the lost portion of the holiday. Mostly relevant for longer trips.
Lost or stolen baggage. Capped at £1,000-£2,000 typically, with a per-item sub-limit (often £200-£300), which means a stolen camera or laptop is rarely fully covered. Useful but not the main event.
Trip delay and missed connections. Pays a small lump sum (£25-£50/hour or capped at £200-£500) for significant delays. Genuinely useful for getting through a long airport delay.
Personal liability cover. If you injure someone or damage their property abroad. Rarely used; cheap to include.
The pricing logic is: medical and cancellation cover drive the premium up, the rest are essentially included. Most arguments about which insurer to pick come down to the medical cover limit and how the policy treats pre-existing conditions.
Annual multi-trip vs single-trip
The split is about how many trips you actually take in a year.
For 2+ trips per year: annual multi-trip wins. £50-£100/year covers an unlimited number of trips of up to 30 days each, which suits the typical UK pattern of a summer holiday plus a couple of city breaks plus the occasional work trip. Comparing to single-trip coverage at £20-£40 each, you'd need only three trips for annual to pay off, and most years feature more.
For one big trip per year: single-trip is slightly cheaper, especially if it's a long trip where annual policies hit the per-trip duration limit.
For families: annual multi-trip family policies (one or two adults plus children up to 18 living at home, sometimes covered up to 23 if in full-time education) at £80-£180/year are excellent value compared to insuring four people separately for each trip.
For business travellers doing 10+ trips a year: a premium annual policy at £100-£200/year is the sensible answer; some employers cover this through corporate travel insurance.
The rule of thumb: book the trip first, then buy insurance the same day. Insurance bought from the airline or booking site at point of purchase is usually 2-3x more expensive than buying via a comparison site.
The £5m vs £10m vs £15m question
Most UK insurers offer medical cover at multiple tiers, and the right answer depends substantially on destination.
For Europe: £5 million is enough. The GHIC card covers state-provided care, the private supplement is mostly for repatriation, evacuation, and the occasional private hospital admission. Even severe scenarios rarely exceed £500,000.
For Asia, South America, Australia, New Zealand: £5-£10 million depending on country. Public healthcare is decent in most of these regions; the policy is mostly there for evacuation home and serious private treatment.
For the United States, Canada: never accept less than £10 million, and £15 million is sensibly conservative. The Florida case wasn't unusual; six-figure US hospital bills for routine admissions are normal. UK travellers underinsuring here have ended up with bills exceeding their cover and the difference falling on them personally.
For cruises: standard £5 million is fine for most cruises, but a cruise add-on is essential. It covers cabin confinement compensation, missed port reimbursement, and most importantly medical evacuation from a ship at sea, which is genuinely expensive (£10,000-£100,000 depending on location).
Pre-existing conditions, honestly
This is the area where most travel insurance claims get refused, and almost always because of non-disclosure rather than the conditions themselves.
The rule is simple: declare every diagnosed condition, every prescription medication, and every major medical event in the past several years (the lookback period varies; usually 2-5 years for most insurers, lifetime for some serious conditions). If the application asks, answer accurately, even at the cost of a higher premium or some specific exclusions.
Common conditions that need declaring: asthma, diabetes (type 1 or 2), heart conditions or events, high blood pressure (treated or untreated), cancer (current or in remission), stroke, mental health conditions on medication, anything hospital-treated in the lookback period.
Specialist insurers exist for declared conditions where mainstream insurers are punitive. AllClear, Saga, Insurance Choice, Staysure all underwrite for higher-risk medical histories at sensible premiums. The premium is typically 30-100% higher than mainstream cover, which is dramatic but not insurmountable.
The consequence of not declaring: full claim refusal at exactly the moment you need the policy. The £40 saved on the premium becomes a £40,000 medical bill paid out of pocket. This is the single most common preventable insurance failure in the UK travel market.
Where to buy
The pricing patterns are consistent: comparison sites (Compare the Market, MoneySupermarket, GoCompare, Confused) almost always beat both direct quotes and travel-agent or airline-add-on insurance. Quote three sites, take the cheapest comparable cover from a recognised insurer.
Names that turn up reliably in the cheapest competitive quotes: Direct Line, Aviva, Post Office, Saga (for over-50s), Coverwise (own-brand from comparison sites), Allianz, AIG. The brand differences are mostly about claims-handling reputation, which is hard to verify until you claim. The comparison-site approach surfaces the price floor; the brand reputation question is whether to pay £10-£20 more for an insurer with better claims-handling track record.
Premium credit cards (Amex Platinum, some Barclays Premier, some HSBC Premier) include travel insurance as a benefit. The cover is often genuine and worth using; the limits are sometimes lower than standalone policies and the pre-existing-condition treatment is sometimes worse. Verify before relying on it.
When you don't need it
The honest cases where travel insurance isn't worth buying:
Domestic UK trips: NHS coverage applies regardless, and the cancellation cover for a £200 weekend in Cornwall isn't worth a £30 policy. Some travellers buy it anyway for the baggage cover, but the maths is thin.
Very short, low-cost trips with no cancellation risk: a Saturday in Paris booked on a £40 Eurostar fare doesn't economically justify £20 of insurance for the medical cover that the GHIC card mostly provides anyway.
Trips covered by an existing premium credit card: verify the limits and exclusions match what you'd buy separately.
For everything else — international travel, high-value bookings, anyone with health conditions, anyone going to the United States — travel insurance is one of the most cost-effective insurance products in the UK. £60-£100/year covers risks that, uninsured, can be life-changing.
Specific scenarios that need add-ons
A few situations where standard travel insurance isn't quite enough:
Skiing or snowboarding. Standard policies typically exclude winter sports. Add-on at £15-£40 covers piste, off-piste in some cases, equipment hire, and lift pass refunds. Essential for any ski trip; medical evacuation off a mountain is otherwise punitively expensive.
Adventure activities. Diving, climbing, paragliding, bungee jumping. Each insurer has a specific list of activities included and excluded. Verify before participating; doing it without cover voids the medical cover for any related injury.
Long trips (over 30 days). Standard annual multi-trip policies typically cap at 30-60 days per trip. Long-stay specialists (True Traveller, World Nomads, Insure & Go) sell extended-trip policies for backpacking and gap years.
Cruises. Standard policies sometimes exclude cruises; cruise add-on is small (£10-£30 per trip) and worth it.
Pregnancy. Standard policies cover pregnancy-related medical care up to about 32 weeks; specifics vary. Declare pregnancy at booking if applicable.
What I'd actually do
For a UK adult with healthy medical history travelling 2-4 times a year: annual multi-trip at £60-£90, £10 million medical cover (£15 million if any USA trip is planned), declare nothing, take it for a few years, switch every 3-4 years for new-customer pricing.
For a family of 4: family annual multi-trip at £100-£180, same medical cover thresholds.
For travellers with declared medical conditions: specialist insurer (AllClear, Saga, Staysure, Insurance Choice), expect £80-£180 instead of £40-£80, take it as the cost of being properly covered.
For a single big trip (a 3-week US holiday, a 6-week trip to Asia): single-trip policy with £15 million medical cover for the US, £10 million elsewhere. Buy on the day of booking.
The one thing that consistently goes wrong is buying the cheapest policy without reading the medical cover limits or declaring conditions accurately. The £30 saved on a budget policy becomes a £40,000 hospital bill the one time it actually matters. Buy decent cover, declare honestly, take the receipt, get on the plane.
