- Standard UK travel policies require cover to start before you leave home. The FCDO guidance advises buying insurance as soon as a trip is booked, not after departure.
- A small number of specialist insurers sell cover to travellers already abroad, but each applies a waiting period before medical cover activates: two days at Globelink, 48 hours at True Traveller and the day after purchase at Voyager Plus.
- Age caps are tighter once you have left home. True Traveller caps already-travelling cover at 65, Globelink at 74, while standard pre-departure policies often run higher.
- Anything that happened before you bought the policy, including known injuries, incurred medical bills or lost baggage, is excluded.
- The ABI reported members paid 472 million pounds across more than 500,000 travel claims in 2024, with medical claims averaging 1,528 pounds.
Buying travel insurance after a trip has already started is the exception, not the norm. The default position across the UK market is that a policy must be in force before departure, and the gov.uk foreign travel insurance guidance frames cover as something to arrange at the point of booking. Travellers who left home uninsured, or whose policy lapsed mid-trip, face a narrower set of options, higher exclusions and a short list of providers willing to write the risk at all.
How cover for travellers already abroad differs
A conventional single-trip or annual policy is priced on the assumption that the insurer takes on the risk from a known start date, with the traveller still at home and nothing yet gone wrong. Selling cover to someone already overseas removes that certainty. The insurer cannot verify the traveller's current health, cannot confirm that no claimable event has already occurred, and is exposed to people who only seek cover once a problem appears.
To manage that exposure, already-travelling policies attach conditions that standard pre-departure policies do not. The most consistent is a waiting period, also described as an exclusion window, during which illness-related medical cover does not apply. Globelink states a two-day waiting period before cover activates. True Traveller applies a 48-hour exclusion period described as an anti-fraud measure. Voyager Plus states cover starts the day after the purchase date, with a further 14-day waiting period for illness-related medical expenses. In each case, an accidental injury that is independently witnessed during the window may still be considered, but illness is the main thing the window is designed to exclude.
What to look for before buying after departure
The first thing to confirm is whether a provider sells this cover at all, because most do not. Among those that do, the practical detail that matters is when medical cover genuinely begins. A policy that activates the day after purchase, then withholds illness cover for a further period, leaves a real gap for anyone who is unwell when they buy.
Age is the next constraint. True Traveller caps its already-travelling cover at age 65 and notes that cover for those 66 and over, once abroad, is not generally available. Globelink extends to 74, with a maximum trip length of 18 months for under-65s and six months for ages 66 to 74. Residency rules also tighten: Globelink restricts already-travelling cover to UK residents, while True Traveller accepts residents of the UK and a defined list of European countries.
One further point separates this cover from a normal policy: the cooling-off period usually disappears. True Traveller states there is no 14-day cooling-off period when already travelling and no premium refund on cancellation. Voyager Plus states the same 14-day cancellation window does not apply once a trip has started. A buyer therefore commits without the usual right to change their mind.
Cover limits and exclusions
Despite the extra conditions, the headline medical limits on already-travelling policies can match standard products. True Traveller advertises 10 million pounds of medical cover on this basis, and Voyager Plus advertises emergency medical expenses up to 10 million pounds alongside curtailment up to 10,000 pounds and baggage up to 3,500 pounds. Globelink describes emergency medical, repatriation and curtailment cover but does not publish a fixed premium, noting price depends on location, age and trip length.
The exclusions are where these policies diverge most sharply from pre-departure cover. Anything that occurred before the policy was bought is excluded outright: a pre-existing injury, medical expenses already incurred, or baggage already lost cannot be claimed. Pre-existing medical conditions are also treated cautiously. Globelink will not accept claims arising from pre-existing conditions unless they fall within its declared no-screen list. Voyager Plus states any medical condition held before taking out the policy is not covered. Trip cancellation, a core benefit of a pre-departure policy, is generally absent because the trip has already begun: Voyager Plus confirms its already-departed policies do not include cancellation cover.
The FCDO guidance is direct about why declaration still matters even mid-trip. Failing to declare existing conditions or pending treatment can invalidate a policy, and the cover should run for the full length of the trip and include emergency transport such as an ambulance, which is often charged separately. The ABI's 2024 claims data underlines the stakes: medical claims reached 262 million pounds, made up 34 per cent of all travel claims, and one member paid over one million pounds for a single hospitalisation and repatriation in the United States.
Providers offering cover in this segment
Three UK-regulated specialists were verified as selling cover to travellers who have already left home, each with distinct rules.
Globelink markets an Already Travelling policy for UK residents up to age 74, with a two-day waiting period and no cover for incidents that occurred before purchase. It trades as Globelink Travel Insurance Consultants Limited and states it is authorised and regulated by the FCA under firm reference 300144.
True Traveller sells already-travelling cover to residents of the UK and listed European countries up to age 65, advertising 10 million pounds of medical cover with a 48-hour exclusion window and no cooling-off period. Its cover is underwritten by Inter Partner Assistance S.A., part of the AXA group, and it states FCA authorisation under FRN 756107.
Voyager Plus offers an already-departed policy with emergency medical cover up to 10 million pounds, cover starting the day after purchase and a 14-day waiting period for illness-related medical expenses, with no trip cancellation benefit. The page identifies the arranging firm as Caledon MGA Ltd, authorised and regulated by the FCA under firm reference 305814.
Beyond these named providers, the category is thin, and offers seen through unsolicited calls or messages should be treated with caution. The safest check is the FCA register, which lists whether a firm is authorised to arrange insurance.
Common pitfalls
The recurring mistake is assuming already-travelling cover behaves like a normal policy bought a day late. It does not. The waiting period means a traveller who falls ill before cover fully activates may have no claim, and the loss of the cooling-off period means there is no refund if the purchase is reconsidered. Buying after a symptom or incident has already appeared will not work, because pre-purchase events are excluded by design.
Age and residency cut-offs catch travellers out too. Someone aged 66 or over who left home uninsured may find no provider will cover them once abroad, which is why the FCDO and ABI both stress arranging cover at the point of booking rather than relying on a fix after departure. A free GHIC is not a substitute: the NHS confirms it covers medically necessary state healthcare in the EEA and some countries but does not cover repatriation, private treatment, or ski and mountain rescue.
