Does holiday insurance cover pre existing conditions?
Standard holiday insurance policies generally do not cover pre-existing conditions unless you specifically declare them and pay any required additional premium. If you fail to disclose a medical condition, your insurer may refuse to pay any claims related to that illness or even cancel your policy entirely. To ensure coverage, you must complete a medical screening process during the application where you list all diagnosed conditions and ongoing treatments. This guide explains how the medical screening process works, the impact of the Global Health Insurance Card (GHIC) on your policy, and how to find specialist cover if a standard provider refuses your application.



Key facts
- Typical cost range
- £15-£85 per person for a typical 1-week trip depending on severity (UK-priced 2026)
- Repatriation cost
- Up to £50,000 for an air ambulance from the USA to the UK
- Disclosure period
- Usually the last 2 to 5 years of your medical history
- GHIC coverage
- Covers state-provided healthcare in the EU but 0% of repatriation costs
- Regulatory requirement
- Insurers must signpost to a specialist directory if they cannot offer cover

TL;DR
Yes, holiday insurance can cover pre-existing conditions, but you must declare them during the application. Standard policies often exclude undeclared illnesses. To be fully protected, complete a medical screening, pay any extra premium, and ensure you are not travelling against medical advice or awaiting test results.

Why declaring medical conditions is essential
When you apply for travel insurance in the UK, the provider assesses the risk of you needing medical treatment while abroad. If you have a pre-existing condition - defined as any illness, injury, or disease you have received treatment or advice for in a set period (usually 2 to 5 years) - the risk to the insurer is higher. Failing to declare these facts is considered non-disclosure. Under the Financial Ombudsman Service (FOS) guidelines, insurers can reject claims if they can prove that the traveller was not honest about their medical history, leading to significant out-of-pocket expenses for emergency care or repatriation.
- Ensures emergency medical expenses are fully covered
- Protects your cancellation cover if you become too ill to travel
- Prevents the policy from being declared void during a claim
- Allows the insurer to provide appropriate 24-hour medical assistance
- Provides peace of mind that your specific health needs are recognised
What is typically covered under medical policies
If you successfully declare your conditions and the insurer accepts them, your policy will cover emergency medical treatment related to those specific ailments. This includes hospital stays, surgery, and prescribed medication while abroad. Most importantly, it covers emergency medical repatriation back to the UK, which can cost tens of thousands of pounds from destinations like the USA or South East Asia. You are also covered for cancellation or curtailment if your pre-existing condition flares up unexpectedly before or during your trip, provided the condition was stable when you bought the policy.
Common exclusions for pre-existing conditions
Even with a medical policy, certain exclusions apply. Most insurers will not cover you if you are travelling against the advice of a doctor or if you are travelling specifically to seek medical treatment abroad. Conditions that are currently under investigation - where you are awaiting a diagnosis or test results - are often uninsurable until a final result is known. Additionally, if your health changes between the time you buy the policy and the date you depart, you must inform the insurer, or any new symptoms may be excluded from the cover.
- Travelling against professional medical advice
- Conditions where a terminal prognosis has been given
- Awaiting results from pending medical tests or scans
- Travelling for the purpose of cosmetic or elective surgery
- Symptoms that were known but not yet diagnosed by a GP
Factors that influence the cost of cover
The cost of holiday insurance for pre-existing conditions is calculated based on several risk factors. The severity of the condition is the primary driver; for example, well-controlled asthma will typically cost less to insure than a recent heart attack or complex diabetes. Age is another significant factor, as older travellers are statistically more likely to require medical intervention. Finally, the destination plays a huge role. Countries with high healthcare costs, such as the USA, Canada, and Spain, will see much higher premiums for medical cover compared to nations with lower costs or reciprocal agreements.
Choosing the right destination and policy type
If you have a serious medical condition, your choice of destination can affect your ability to get cover. Within the EU and Switzerland, the UK Global Health Insurance Card (GHIC) provides access to state-provided healthcare at a reduced cost, which some insurers view favourably. However, the GHIC is not a substitute for insurance as it does not cover repatriation. For those with complex histories, the MoneyHelper directory, recommended by the Financial Conduct Authority (FCA), lists specialist providers who focus exclusively on high-risk medical cases that standard high-street insurers might decline.
Evidence required for medical claims
To make a successful claim related to a pre-existing condition, you must provide comprehensive evidence to your insurer. This usually begins with a medical certificate from the treating doctor abroad detailing the nature of the emergency. You will also need to grant the insurer access to your UK GP records so they can verify that the condition was accurately declared at the time of purchase. Keeping a log of all communications with the insurer's 24-hour medical assistance line is vital, as they often need to pre-authorise expensive treatments or hospital admissions.
- A formal diagnosis from the attending physician abroad
- Receipts for all medications and hospital fees paid
- Contact details for the hospital and treating consultant
- Access to your UK medical history for verification
- Proof of any travel disruptions caused by the illness
The role of the GHIC and FCDO advice
The Foreign, Commonwealth and Development Office (FCDO) advises all UK travellers to have appropriate insurance, especially those with health issues. While the GHIC offers some protection in Europe, the FCDO website clarifies that it will not pay for your flight home if you are bedbound. Furthermore, if you travel to a country where the FCDO has advised against 'all' or 'all but essential' travel, your insurance policy, including medical cover, will likely be invalidated. Always check the current FCDO status for your destination before booking your trip or buying insurance.
Practical checklist for medical declarations
Before starting your insurance application, gather all necessary information to ensure your declaration is accurate. You should have a list of all medications, the dates of any surgeries or hospital admissions, and the specific names of your conditions. If you are unsure about a diagnosis, consult your GP first. Accuracy is more important than speed; even a small error in the name of a medication can lead to complications during a claim. Once the policy is issued, check the 'Medical Declaration' section of your policy schedule to confirm every condition is listed correctly.
