Introduction
Travelling with a pre-existing medical condition does not mean you cannot get travel insurance, but it does mean the process usually looks different from a standard policy purchase. Insurers need to understand your condition to price and structure cover appropriately, and getting this step wrong is one of the most common reasons claims are later rejected.
This guide builds on the medical conditions section in our main Travel Insurance UK guide, focusing specifically on how declaration, screening and specialist cover work.
What Counts as a Pre-Existing Condition?
Insurers generally define a pre-existing condition as any diagnosed illness or condition you have received treatment, medication, advice or investigation for within a set period before you buy the policy, commonly the previous 12 to 24 months, though the exact window varies by insurer.
Conditions Are Often Broadly Defined
Even conditions that feel minor or well-controlled, such as high blood pressure managed with medication, are typically still classed as pre-existing and must be declared during screening.
The Medical Screening Process
Most insurers that accept pre-existing conditions use a medical screening process, either online or by phone, where you answer specific questions about each condition, including diagnosis date, current treatment and any recent changes.
Be Accurate and Complete
Screening questions are designed to build an accurate risk picture. Answering vaguely or omitting a condition you consider unimportant can affect your cover later, even if that specific condition seems unrelated to your eventual claim.
Why Undeclared Conditions Invalidate Claims
Travel insurance pricing and terms are based on the information you provide. If a condition is not declared, the insurer has not had the opportunity to assess or price that risk, which is why undisclosed conditions are treated seriously.
Changes in Health Before You Travel
If your health changes, or you receive a new diagnosis, after buying your policy but before you travel, check whether you need to inform your insurer, as some policies require this.
Specialist Medical Travel Insurers
Where a mainstream insurer declines cover or applies restrictive terms, specialist medical travel insurers who focus specifically on higher-risk or complex conditions may be able to offer more suitable cover.
What to Expect
Specialist insurers often ask more detailed medical questions and may charge higher premiums, but can provide cover, and sometimes cover for the declared condition itself, where a general insurer would exclude it entirely.
Comparing Specialist Quotes
Because pricing and willingness to cover specific conditions varies significantly between specialist insurers, it is worth obtaining more than one quote rather than accepting the first offer.
If your condition affects a pet rather than yourself, our Pre-Existing Conditions and Pet Insurance UK guide explains how a similar principle applies to pet cover.
Reducing Cost While Staying Covered
Compare Annual and Single Trip Options
If you travel more than once a year, compare whether an annual multi-trip policy that accepts your condition works out cheaper than buying single trip cover repeatedly. See our Annual Multi-Trip Travel Insurance UK guide.
Review Cover Annually
Your condition, treatment and risk profile can change over time, so it is worth re-screening and comparing cover at each renewal rather than automatically accepting the same insurer's renewal price.
Frequently Asked Questions About Travel Insurance and Medical Conditions
Can I get travel insurance with a pre-existing medical condition?
In most cases yes, though you will usually need to declare the condition during a medical screening, and cover may come with a higher premium or, in some cases, specific exclusions.
What counts as a pre-existing medical condition for travel insurance?
Generally any diagnosed condition you have received treatment, medication or advice for within a period defined by the insurer, often the past 12 to 24 months, though definitions vary.
What happens if I don't declare a medical condition?
Undeclared pre-existing conditions are one of the most common reasons travel insurance claims are rejected, and can invalidate cover for related and sometimes unrelated claims.
Are specialist medical travel insurers more expensive?
Premiums are often higher than standard policies to reflect the increased risk, but specialist insurers may still offer cover where a mainstream insurer would decline or heavily restrict it.
Does a GHIC replace the need for travel insurance with a medical condition?
No, a Global Health Insurance Card provides access to state healthcare in the EU but does not cover repatriation, private treatment or many other costs that travel insurance addresses.
Conclusion
A pre-existing medical condition should not stop you travelling, but it does mean taking the declaration and screening process seriously. Being accurate and complete when declaring conditions, and comparing specialist insurers where needed, gives you a far better chance of having a valid claim accepted if you need medical treatment abroad.
