TL;DR: Last minute travel insurance is available to purchase up to and including the day of departure, but the later you buy, the fewer benefits are active. Cancellation cover only begins from the purchase date - events that occur between booking the trip and purchasing the policy are not covered. The 14-day FCA cooling-off period still applies but is practically limited close to departure. Retrospective cover for incidents that have already occurred is not available.
KEY FACTS

What last minute travel insurance covers and when cover starts
Last minute travel insurance is standard travel insurance purchased close to the departure date rather than at the time of trip booking. It is available from most travel insurance providers up to and including the day of departure, and in some cases at the airport itself. The policy provides the same scope of cover as a standard travel insurance policy - medical expenses, emergency assistance, baggage, personal liability, and cancellation for covered reasons. The critical distinction from a policy purchased at the time of booking is the effective date of cancellation cover. Cancellation cover starts from the date the policy is purchased, not from the date the trip was booked. If you book a holiday in January, purchase travel insurance in February three weeks before departure, and fall ill in the period between January and February, any cancellation claim arising from that illness is not covered - it predates the policy. The practical consequence of late purchase is a shorter window of cancellation protection, which for most travellers represents the loss of the main financial benefit of purchasing insurance at all.
The purchase date gap - what is not covered
The gap between trip booking and policy purchase is the most significant financial risk of last minute insurance buying. Cancellation claims are the most common type of travel insurance claim submitted by UK travellers (ABI, abi.org.uk). The majority of cancellation events - illness of the traveller or a close family member, bereavement, redundancy - can occur at any point between booking and departure. A traveller who books a holiday six months in advance and purchases travel insurance one week before departure has six months of uninsured cancellation exposure. If a parent is diagnosed with a serious illness two months before the trip and the traveller needs to cancel, no cancellation claim is available because the diagnosis predates the policy. The ABI's guidance on travel insurance recommends purchasing at the time of booking precisely to eliminate this gap. The later the purchase, the more certain it is that any pre-existing circumstances known at the purchase date - a family member's deteriorating health, a known industrial dispute at the destination airport, a named storm already publicised - will be excluded from cover as a known risk at the inception date.
The 14-day cooling-off period and its practical limits
Under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 (legislation.gov.uk), consumers who purchase travel insurance online have a statutory 14-day right to cancel the contract and receive a full refund, provided they have made no claim. This cooling-off right is standard across FCA-regulated insurance products and is not conditional on the reason for cancellation. For last minute travel insurance purchased close to departure, this right exists in law but has limited practical value. If a policy is purchased three days before departure and the consumer wishes to exercise their cooling-off right, the 14-day cancellation window extends beyond the return date of the trip. In these circumstances, most consumers will either travel with the cover or forgo the trip - the cooling-off right is not relevant to the immediate situation. The FCA's Consumer Duty guidance requires insurers to disclose the cooling-off right clearly at the point of sale even where it is of limited practical utility for last-minute purchasers.
Known risks at the time of purchase - the foreseeability exclusion
A fundamental principle of insurance is that cover is available for unforeseen events - not for circumstances already known at the time the policy is entered into. When purchasing last minute travel insurance, any risk that has already materialised or that is publicly known at the purchase date is not insurable. Specific examples include: a named hurricane or tropical storm that has been publicly identified and tracked before the purchase date - insurers typically suspend sales of new policies to affected destinations once a named storm is publicised; industrial action at an airport or by an airline that has been announced before the purchase date; FCDO travel advisories advising against travel that were in force before purchase; and a medical condition that has already manifested symptoms before the policy was purchased and for which the traveller has sought or is seeking treatment. The ABI confirms that travel insurance is not designed to cover risks that are already known at the time of purchase (abi.org.uk). Purchasing a policy after a risk has materialised does not create cover for that risk.
Trips booked after the policy purchase date
Annual multi-trip travel insurance creates a specific last minute scenario that operates in reverse: a consumer holds an annual policy and books a trip after the policy was purchased. In this case, the cancellation cover for the new trip runs from the date the trip was booked - the policy was already in force, so any cancellation event occurring between the booking date and the departure date is within the policy period and potentially claimable. This is one of the practical advantages of purchasing an annual policy at the start of the travel year rather than single-trip policies for each booking. For consumers who book trips spontaneously and frequently, an annual policy provides cancellation cover from the booking date of each trip without any purchase-date gap. Single-trip policies purchased after the booking date carry the gap described above. If a trip is booked and a single-trip policy purchased on the same day, the gap is eliminated and full cancellation cover runs from booking and purchase date simultaneously.
Medical cover - available regardless of purchase timing
While cancellation cover is significantly affected by last minute purchase timing, medical cover under a travel insurance policy is available from the moment the policy is purchased and applies for the duration of the trip regardless of when the policy was bought. A traveller who purchases insurance at the airport on departure day has full medical expenses cover, emergency assistance, and repatriation cover for the trip. These benefits are not diminished by the late purchase - they respond to events that occur during travel, not before it. The practical limitation for last minute medical cover is the pre-existing condition declaration. Any condition for which the traveller is already under investigation, treatment, or awaiting a diagnosis at the time of purchase must be declared. A condition that has been symptomatic but undiagnosed before purchase - and that is subsequently diagnosed and treated abroad - may be treated as a known circumstance at inception if the pre-purchase symptoms were material. Declare any ongoing medical concern at the time of purchase regardless of diagnostic status.

Frequently Asked Questions
Can I buy travel insurance on the day of departure?
Yes. Most UK travel insurance providers allow purchase up to and including the departure date, and some airport outlets sell policies at the terminal. Medical cover, baggage cover, and liability cover are active from the moment of purchase. Cancellation cover is active from purchase but covers only events occurring after the purchase date.
If I buy travel insurance after booking my holiday, am I covered for cancellation?
Cancellation cover runs from the policy purchase date. Any event that occurs between the booking date and the purchase date - illness, bereavement, redundancy - is not covered as a cancellation claim because it predates the policy. The ABI recommends purchasing travel insurance at the same time as booking the trip to eliminate this gap entirely.
Does the 14-day cooling-off period apply to last minute travel insurance?
Yes. Under the Consumer Contracts Regulations 2013, the 14-day right to cancel for a full refund applies to all online travel insurance purchases provided no claim has been made. For policies purchased close to departure, this right exists in law but is of limited practical use as the trip typically falls within the cooling-off window.
Can I get travel insurance that covers a risk I already know about?
No. Insurance covers unforeseen events. Known risks at the time of purchase - a named storm, an announced airline strike, a diagnosed medical condition - are not insurable under a policy purchased after the risk became known. Any product purporting to offer retrospective cover for a known risk is not a genuine FCA-regulated insurance contract.
Does an annual policy provide better last minute cover than a single-trip policy?
For spontaneous or frequent travellers, yes. An annual policy already in force covers each new trip from the booking date rather than from a separate purchase date. This eliminates the gap between trip booking and policy purchase that affects single-trip last minute purchases. If a trip is booked and a single-trip policy purchased on the same day, the gap is also eliminated.
