Declaring pre-existing medical conditions when buying travel insurance is essential, yet it is something many travellers get wrong, sometimes with serious consequences. Failing to declare a condition can mean a claim is refused when you need it most. This guide explains how to declare pre-existing medical conditions for travel insurance and why it matters. It is general information, not financial or medical advice, so always follow your insurer's process and read the terms carefully.
What a pre-existing condition is
A pre-existing medical condition is generally a health condition you already have or have had, which insurers take into account when providing cover. This can include ongoing conditions, past serious illnesses, and conditions you are receiving treatment or medication for. The exact definition varies between insurers, so check how each defines it. Understanding that a wide range of past and current health matters may count as pre-existing is the first step to declaring correctly and ensuring you are properly covered.
Why you must declare them
You must declare pre-existing conditions because insurers base your cover and premium on the risk, and undeclared conditions can invalidate related claims. Travel insurance is provided on the understanding that you have given accurate information, so withholding a condition breaches that and can leave you unprotected. Declaring ensures the insurer can cover you properly, or tell you if they cannot. Being upfront about your health is not optional; it is fundamental to having insurance that will actually pay out when you need it.
What happens if you do not declare
The consequences of not declaring a pre-existing condition can be severe. If you make a claim related to an undeclared condition, the insurer may refuse to pay, leaving you facing potentially enormous medical bills abroad with no cover. They may even cancel the policy. This is precisely the situation insurance is meant to prevent, so failing to declare defeats the purpose entirely. The risk of a refused claim makes honest, full declaration essential, however tempting it might be to keep quiet to lower the premium.
How declaring works
When you buy travel insurance, you will usually go through a medical screening process, answering questions about your health and any conditions, often online. The insurer uses your answers to decide whether and how it can cover you and at what premium. It is important to answer fully and accurately, declaring everything asked about. Our guide on how to choose travel insurance covers the wider buying process. Completing the medical screening honestly and carefully is how you ensure your conditions are properly accounted for in the cover.
It may affect the premium
Declaring a pre-existing condition can increase the premium, because it may raise the insurer's assessment of risk, and in some cases an insurer may exclude a particular condition or decline to cover it. While a higher premium is unwelcome, it is far better than an unpaid claim. The increase reflects the genuine cover you are getting for your situation. Accepting that a medical condition may cost a little more to insure, rather than hiding it, is the sensible price of having protection that will actually work.
Where to find suitable cover
If a mainstream policy is expensive or will not cover your condition, specialist insurers focus on cover for people with medical conditions, including more serious ones, and can often provide suitable policies. It is worth shopping around, as premiums for the same condition can vary. Comparison tools and specialist providers can help. Our guide on travel insurance for over-65s and older travellers is relevant, as age and health often go together. Looking beyond standard policies can find affordable cover for declared conditions.
Do not avoid declaring to save money
It can be tempting to leave out a condition to get a cheaper premium, but this is a serious mistake that defeats the entire point of insurance. A cheaper policy that will not pay out when you need it is worthless, and you could be left facing huge costs. The small saving from not declaring is never worth the risk of a refused claim. Treating full declaration as non-negotiable, and accepting any extra cost it brings, is the only sensible approach to insuring with a medical condition.
Be honest and accurate
When declaring, be completely honest and accurate, answering all the medical questions fully and not glossing over or forgetting anything relevant. If you are unsure whether something counts, declare it or ask the insurer. Inaccurate or incomplete information, even if unintentional, can affect a claim. Taking care to provide a complete and truthful picture of your health, and checking you have not omitted anything, ensures the cover you buy is valid and that there will be no disputes if you need to claim.
Sort medical cover early
Arrange your insurance, including declaring conditions, as soon as you book your trip, so you have cover from the outset and time to find a suitable policy if your situation is complex. Leaving it late can mean rushing the screening or struggling to find cover. Our guide on when to buy travel insurance explains the timing. Sorting medical cover early, with conditions properly declared, means you are protected from booking and avoids a last-minute scramble for a policy that fits your needs.
Keep records
Keep a record of what you declared and the policy documents confirming your cover, so you have evidence of the information you provided if you ever need to claim. Having proof that you declared your conditions accurately protects you in any dispute. Keeping your policy paperwork and a note of the medical details you gave, both before and during your trip, is good practice. Good records make any claim involving a pre-existing condition smoother and support the validity of the cover you bought.
Declare conditions for everyone on the policy
If your policy covers more than one person, such as a couple or family policy, the medical conditions of everyone insured must be declared, not just the main policyholder. An undeclared condition affecting any covered traveller could lead to a refused claim. Our guide on family travel insurance covers cover for groups. Making sure every person on the policy has their conditions declared, rather than just the person buying it, ensures the cover is valid for the whole family or group, not only for one member.
If your health changes after buying
If your health changes after you buy a policy but before you travel, for example a new diagnosis or a change in treatment, tell your insurer, as they may need to update your cover. Failing to inform them of a relevant change could affect a claim. Policies usually require you to keep the insurer informed of significant health changes. Letting your insurer know promptly if your medical situation changes between buying the policy and travelling keeps your cover valid and avoids problems if you later need to claim.
In short
You must declare pre-existing medical conditions when buying travel insurance, as undeclared conditions can lead to refused claims and huge bills abroad. Declaring is done through a medical screening, and may raise the premium or require a specialist insurer, but that is far better than being uninsured. Be honest and accurate, do not omit conditions to save money, sort cover early and keep records. This is general information, not financial or medical advice, so follow your insurer's process.
