A third of travellers with pre-existing medical conditions admitted they will not declare all of them when buying travel insurance this summer, up from a quarter in the spring, according to research from travel insurer AllClear1. The findings were reported by Which? on 21 August 20241.
The research is based on surveys of travellers carried out every three months since 2021, and also identified large numbers of customers "cutting corners" in other ways to save money1. Half of those with conditions said they would not bother getting insurance at all for short-haul holidays, such as to France, Spain, Ireland or Italy1. AllClear says this forms part of a larger trend in which travellers are placing less emphasis on safety abroad and more on cutting costs, as the cost of living crisis replaced the pandemic in shaping priorities1.
Separate survey research commissioned by Multitrip.com found that 22% of holidaymakers have had to see a doctor while travelling and 15% have had to go to the hospital1. Where a medical condition is not declared, this can potentially invalidate any claim connected to that condition1.
Which? sets out eight points for buying travel insurance with medical conditions1. It says that if a condition is not stated explicitly as included in the policy documentation, it is typically excluded by default, and that where an insurer has not asked about medical history during the purchase, the customer will generally need to contact it separately to have conditions added1. It adds that most insurers require customers to report changes in health since taking out cover or booking the holiday, including new diagnoses, changes in medication, medical investigations or tests, and new symptoms; the insurer will then re-evaluate the cover, which can mean a changed premium, added exclusions or a decision to decline cover, and a failure to disclose a change may invalidate the cover1.
On finding cover, Which? says comparison websites do not give the full picture because not all insurers, including many medical specialists, are listed on them1. It names two accredited directories:
| Directory | Run by |
|---|---|
| Travel insurance directory | Moneyhelper |
| Travel medical directory | British Insurance Brokers' Association |
The British Insurance Brokers' Association also runs a "Find Insurance" service to help customers find brokers with expertise to track down suitable cover1.

Why it matters for households
Travellers who buy travel insurance with pre-existing medical conditions and leave a condition off the application risk having a related claim refused, which can mean meeting medical bills or cancellation costs themselves1. The same applies where a condition is not explicitly included in the policy wording, since it is typically excluded by default1.
The change in declared behaviour is measured between spring and summer 2024, so it describes intentions for this summer's trips rather than completed purchases1. The share saying they would not declare all conditions rose from a quarter to a third over that period1.
The rules on giving wrong information to an insurer and on answering an insurer's questions honestly cover non-disclosure and its effect on claims. For people who find cover hard to obtain, the two directories and the brokers' finder service are routes to specialist providers that do not appear on comparison sites1.
What happens next
No further dates have been reported. AllClear's surveys are conducted every three months, so a further set of findings would be expected after the summer1.
