Medical Questions When Buying a Policy
Answering medical questions travel insurance providers ask is a mandatory part of the application process for any UK resident. You must declare all pre-existing conditions, including chronic illnesses and recent surgeries, to ensure your policy remains valid for emergency treatment abroad. Failing to disclose your full medical history can result in a claim being rejected or your entire policy being voided. This guide explains how medical screening works, what constitutes a pre-existing condition, and how to answer insurer queries accurately to protect your holiday investment.

TL;DR

Why medical disclosure is essential
When you apply for travel insurance in the UK, the insurer needs to assess the risk of you requiring medical assistance while away. Medical costs in countries like the USA or Spain can reach tens of thousands of pounds for even minor procedures. By answering medical questions accurately, you establish a fair premium based on your health profile. If you omit details about a condition, the insurer is legally entitled to refuse payment for any related medical emergency, leaving you personally liable for the bills. Honesty is the only way to guarantee that your policy provides the financial safety net you expect.
- Ensures emergency medical expenses are fully covered
- Prevents the policy from being declared void
- Protects against the high cost of overseas repatriation
- Allows insurers to suggest specialist cover if needed
- Provides peace of mind for travellers with chronic illness
What counts as a pre-existing condition?
In the UK insurance market, a pre-existing condition is generally defined as any medical issue for which you have received treatment, medication, or a diagnosis within a specific timeframe - often the last two to five years. This includes chronic conditions like asthma or diabetes, as well as temporary issues like a broken bone or a recent bout of anxiety. You must also declare conditions that are currently under investigation, even if you have not yet received a formal diagnosis. Insurers use this data to determine if your health status increases the statistical likelihood of a claim during your trip.
- High blood pressure or cholesterol levels
- Heart-related conditions and strokes
- Respiratory issues including severe asthma or COPD
- Cancer, even if currently in remission
- Mental health conditions such as depression or PTSD
- Diabetes (Type 1 or Type 2)
- Joint or bone problems requiring ongoing care
What is typically excluded from cover?
Even with full disclosure, certain scenarios may be excluded from standard policies. Most insurers will not cover claims arising from a terminal prognosis where the life expectancy is less than six months at the time of travel. Additionally, you cannot usually claim for medical issues if you are travelling against the advice of a GP or a qualified medical professional. Routine check-ups, elective cosmetic surgeries, and non-emergency treatments are also standard exclusions. If you are waiting for an operation or a specialist consultation, many insurers will exclude that specific condition until the treatment is completed and you are discharged.
Factors that influence your premium
The price of your travel insurance is determined by several variables beyond just your age and destination. When you answer medical questions, the severity of the condition and the medication required will impact the cost. For example, well-controlled high blood pressure might result in a negligible price increase, whereas a recent heart attack will significantly raise the premium due to the higher risk of a complications. The destination also matters; medical inflation in the USA and Canada means that a pre-existing condition will cost more to insure for a trip to New York than it would for a trip to France.
- The specific type and severity of the condition
- The number of different medications prescribed
- How recently you were hospitalised for the illness
- The duration and location of your holiday
- The level of excess you agree to pay on a claim
Choosing the right cover for your health
If you have complex medical needs, a standard high-street policy might not be sufficient. You should look for specialist medical travel insurance providers who focus on higher-risk cases. These insurers use more detailed screening tools to offer tailored cover that may be unavailable elsewhere. It is also vital to check the 'repatriation' limits of a policy. This covers the cost of flying you back to the UK in an air ambulance if you are too unwell to travel on a commercial flight. Always compare the total medical limit, which should ideally be at least £2 million for Europe and £5 million for worldwide destinations.
Evidence required during a claim
If you need to make a claim for medical expenses, the insurer will require evidence to verify that your initial declarations were honest. They will often request access to your NHS medical records to see if the illness that caused the claim was linked to an undeclared pre-existing condition. You will also need to provide itemised bills from the hospital abroad and a medical report from the treating doctor. If the claim is due to a cancellation before you travel, you will need a certificate from your UK GP confirming that you are unfit to fly. Keeping a clear paper trail is essential for a successful settlement.
The role of the GHIC and FCDO
The Global Health Insurance Card (GHIC) allows UK residents to access state-provided healthcare in EU countries at a reduced cost or for free. However, the GHIC is not a substitute for travel insurance; it does not cover private medical costs or mountain rescue. The Foreign, Commonwealth and Development Office (FCDO) advises all travellers to take out comprehensive insurance that covers their specific medical needs. If you travel to a destination where the FCDO advises against 'all travel' or 'all but essential travel', your insurance policy - including medical cover - will likely be invalidated unless you have a specialist high-risk policy.
- GHIC covers state healthcare in the EU and Switzerland
- Insurance is still needed for repatriation to the UK
- FCDO advice must be checked before departure
- GHIC does not cover medical costs in the USA or Asia
- The ABI recommends declaring all health changes before travel
Practical checklist for medical screening
Before starting your insurance application, gather all necessary information to ensure your answers are precise. Having your medication names and dosages to hand will make the online screening process much smoother. Remember that the duty of disclosure continues even after you have purchased the policy; if your health changes or you are prescribed new medication before you depart, you must inform your insurer immediately. Taking fifteen minutes to double-check your medical history can prevent a financial disaster later. Always read the policy wording to understand exactly what is covered in relation to your specific health conditions.
