TL;DR: Travellers with pre-existing medical conditions must declare all conditions honestly when applying for UK travel insurance. Insurers assess stability, recent treatment, and medication before offering cover, loading premiums, applying exclusions, or declining. Specialist insurers exist for complex cases. The Consumer Insurance (Disclosure and Representations) Act 2012 makes accurate declaration a legal requirement, and non-disclosure can void any claim.

How UK Insurers Assess Pre-Existing Medical Conditions
When a traveller declares a pre-existing medical condition on a travel insurance application, the insurer uses a medical screening process to assess the risk. This process typically involves a structured questionnaire covering the type of condition, the date of diagnosis, the current treatment and medication, whether the condition has been stable in the past 12 to 24 months, and whether the applicant has been hospitalised or attended an accident and emergency department recently. The definition of a pre-existing medical condition varies between policies. Some define it as any condition for which the applicant has received treatment, medication, or medical advice in the past two years. Others apply a five-year or lifetime look-back window. Conditions that are chronic by nature, such as diabetes, heart disease, asthma, or cancer, will almost always fall within any look-back period and must be declared regardless of how long they have been diagnosed. The outcome of the assessment falls into one of four categories: the condition is accepted at standard pricing, the condition is accepted with a premium loading reflecting the additional risk, the condition is accepted but excluded from the cover so that claims arising from it will not be paid, or the insurer declines to offer any cover at all. The outcome depends on the insurer's underwriting rules and the specific clinical picture presented by the applicant. Stability is one of the most important factors: a condition that has been unchanged for 12 months or more with no medication adjustments is typically assessed more favourably than a condition that has recently changed or deteriorated.
What You Are Legally Required to Declare
The Consumer Insurance (Disclosure and Representations) Act 2012 sets out the standard of care required of consumers when completing insurance applications. Applicants must take reasonable care not to make a misrepresentation in answer to the insurer's questions. In practice, this means answering all medical screening questions honestly and completely, declaring all known conditions whether or not the applicant considers them relevant to travel. A common mistake is to omit a condition on the grounds that it seems minor, is well-controlled, or has not caused recent symptoms. This approach carries significant risk. If a claim arises and the insurer investigates, it may discover the undisclosed condition through medical records obtained with the applicant's consent during the claims process. Where a material connection between the undisclosed condition and the claim is established, the insurer may reduce or void the settlement. The Financial Ombudsman Service has published guidance confirming that for an insurer to fully repudiate a claim on non-disclosure grounds, it must typically show the non-disclosure was deliberate or reckless. For innocent non-disclosure, the insurer is entitled to treat the claim as it would have done had full disclosure been made, which in practice may mean a proportional reduction. Neither outcome is desirable. The same declaration obligations apply at annual renewal: if a condition has changed, worsened, or a new diagnosis has been made since the policy was last taken out, the updated information must be provided at renewal.
Cover Outcomes: From Full Cover to Specialist Referral
The range of outcomes following medical declaration is broader than many applicants realise. At the favourable end of the spectrum, a condition that is mild, stable, and well-managed may be accepted at standard pricing by mainstream insurers, meaning no additional cost compared with a traveller without the condition. Moving along the spectrum, a condition that carries a higher risk of emergency treatment abroad may attract a premium loading: the insurer accepts the risk but charges more for doing so. A further outcome is the application of a medical exclusion: the insurer offers a policy at standard or slightly elevated pricing, but includes a specific exclusion for claims arising from the declared condition. This means the traveller has cover for all other travel risks, including cancellation, baggage, and unrelated medical emergencies, but will not be reimbursed for costs directly attributable to the excluded condition. This type of cover may be suitable for travellers who are willing to self-fund the risk of a condition-related incident, or who are travelling to an EU or EEA destination where a GHIC provides a degree of state healthcare safety net. At the least favourable end of the spectrum, an insurer may decline to offer any cover. In this case, the ABI's signposting requirement means the insurer or platform must direct the applicant to specialist providers. The MoneyHelper directory at moneyhelper.org.uk and the BIBA find-a-broker tool are the primary routes to finding specialist medical travel insurance in the UK.
Specialist Insurers and the MoneyHelper Directory
Specialist medical travel insurers occupy a distinct segment of the UK market, focused on providing cover to travellers who have been declined or offered only exclusionary cover by mainstream providers. These insurers typically conduct more detailed underwriting, involving longer medical questionnaires and in some cases requiring a letter from the applicant's GP or consultant before a quote is provided. This additional rigour allows specialist insurers to price complex risks more accurately and, in many cases, to include pre-existing condition-related emergency claims within the policy rather than excluding them. The MoneyHelper travel insurance directory at moneyhelper.org.uk is a government-backed, free-to-use resource listing specialist providers who cover a wide range of medical conditions. The British Insurance Brokers Association (BIBA) operates a find-a-broker service at biba.org.uk that connects applicants with experienced medical travel insurance brokers who can search across multiple specialist providers. When approaching specialist insurers, applicants should prepare a full summary of each condition, including the diagnosis date, current treatment and medication, the date of any hospitalisation or surgery, and the outcome of the most recent medical review. Accurate and complete information at the application stage reduces the risk of a disputed claim and speeds the underwriting process. Premium loadings from specialist providers reflect the actual risk assessed after detailed underwriting and may be lower than applicants expect, particularly for conditions that are stable and well-managed.
Practical Considerations: GHIC, Medication and FCDO Advice
Beyond the insurance policy itself, travellers with pre-existing conditions should take several practical steps before travelling. The UK Global Health Insurance Card (GHIC), available free from the NHS Business Services Authority at nhsbsa.nhs.uk, provides access to medically necessary state-provided healthcare in EU and EEA countries at the same cost as a local resident. For travellers whose condition might require hospital treatment in Europe, the GHIC provides a valuable supplementary safety net. However, it does not cover repatriation, private hospitals, cancellation, or care outside the state system, and it is not a substitute for a travel insurance policy that includes the declared condition. Travellers carrying prescription medication abroad should obtain a GP letter confirming the diagnosis and prescription, carry sufficient medication for the entire trip plus a buffer in case of delays, and keep medication in hand luggage where appropriate. Some medications, particularly controlled drugs such as pregabalin, opioids, and certain anxiolytics, are subject to import restrictions in various countries. The UK Government's foreign travel advice pages at gov.uk/foreign-travel-advice carry country-specific health and entry information, and gov.uk/travelling-controlled-drugs provides guidance on controlled drug export licences. The Foreign, Commonwealth and Development Office (FCDO) advice pages also carry health recommendations for individual destinations, which may be relevant for conditions that are sensitive to altitude, heat, or local air quality.

Frequently Asked Questions
What counts as a pre-existing medical condition for travel insurance?
Most UK travel insurance policies define a pre-existing medical condition as any illness, injury, or medical condition for which the applicant has received a diagnosis, treatment, medication, or medical advice within a defined look-back period, typically two to five years. Chronic or lifelong conditions such as diabetes, heart disease, and asthma are almost always covered by this definition regardless of the look-back window, and must be declared on every application. The exact definition varies between policies and should be read carefully in the policy wording before purchase.
What happens if I do not declare a pre-existing condition?
Under the Consumer Insurance (Disclosure and Representations) Act 2012, failing to declare a material pre-existing condition is a misrepresentation. If a related claim arises, the insurer may reduce or void the claim. For deliberate or reckless non-disclosure, the insurer can void the policy entirely. The Financial Ombudsman Service at financial-ombudsman.org.uk can adjudicate on disputed non-disclosure cases, but the process is time-consuming and outcomes are not guaranteed. Accurate declaration at the outset is strongly preferable.
Can I still get cover if my condition is serious?
Yes, in most cases. Specialist medical travel insurers are able to offer cover for a wide range of serious conditions, often including cancer, recent cardiac events, and chronic autoimmune diseases. The MoneyHelper travel insurance directory at moneyhelper.org.uk and the BIBA find-a-broker service at biba.org.uk are the primary UK resources for finding specialist cover. The ABI's signposting requirement means any mainstream insurer that cannot offer suitable cover must direct applicants to these resources.
Does a GHIC replace travel insurance for people with pre-existing conditions?
No. A UK Global Health Insurance Card, available free from nhsbsa.nhs.uk, provides access to state-provided healthcare in EU and EEA countries. It does not cover repatriation, cancellation, private hospital care, or treatment in countries outside the EU and EEA. For travellers with pre-existing conditions whose treatment abroad could involve repatriation or extended hospitalisation, a travel insurance policy that includes the declared condition is essential alongside the GHIC.
Where can I complain if a claim related to a pre-existing condition is refused?
If a travel insurance claim is refused and the insurer's internal complaints process has not resolved the matter within eight weeks, the complaint can be taken to the Financial Ombudsman Service at financial-ombudsman.org.uk at no cost to the consumer. The FOS can direct insurers to pay claims where the decision is found to be unfair. Complaints must be submitted within six months of receiving the insurer's final response letter.
