Do you need to declare health conditions for travel insurance

Yes. If you buy travel insurance in the UK, you must declare any pre-existing medical conditions your insurer asks about. Getting this wrong is one of the most common reasons travel insurance claims are rejected.

Whether you are booking a family holiday to Spain, a city break in Europe or a long-haul trip, it pays to understand how medical declarations work before you fly. In this guide we explain what counts as a pre-existing condition, what happens if you don't declare it, and how travel insurance differs from the flight delay compensation you may be owed under UK261 and EU261.

Why you must declare pre-existing medical conditions

UK travel insurance is priced on risk. If you have a medical condition, there is a higher chance you may need treatment abroad, cut your trip short or cancel altogether. Insurers ask health questions so they can price your policy fairly.

Under the Consumer Insurance (Disclosure and Representations) Act 2012, you have a duty to take reasonable care not to make a misrepresentation. In plain English, that means answering the insurer's medical screening questions honestly and fully. You don't have to volunteer information they don't ask about, but you must not give false or misleading answers.

Declaring a condition does not automatically mean a higher premium. Many well-controlled conditions add little or nothing to the cost of cover, and some insurers specialise in medical travel insurance.

What counts as a pre-existing medical condition?

Each insurer defines it slightly differently, so always read the wording carefully. As a rule of thumb, you are likely to need to declare:

• Any ongoing condition you take prescribed medication for, such as diabetes, asthma, high blood pressure or epilepsy
• Heart conditions, strokes, cancer or respiratory illnesses, past or present
• Mental health conditions, including anxiety and depression
• Anything you are waiting for tests, treatment or a diagnosis for
• Surgery, hospital stays or outpatient treatment within the period the insurer asks about (often the last two to five years)
• Pregnancy complications, if the policy asks

If you are unsure whether something counts, declare it or call the insurer. It is far better to ask the question before you travel than to have a claim refused afterwards.

Remember that your duty can continue after you buy. If your health changes between buying your policy and travelling, tell your insurer straight away.

What happens if you don't declare a medical condition?

If you fail to declare a relevant condition, your insurer may refuse to pay a claim, even if the claim seems unrelated to your health. Depending on whether the mistake was careless or deliberate, the insurer can:

• Reduce the amount it pays out
• Refuse the claim entirely
• Cancel your policy and keep your premium (for deliberate or reckless non-disclosure)

The financial risk is real. Emergency medical treatment, hospital stays and repatriation flights abroad can run into thousands or even tens of thousands of pounds, particularly in countries such as the USA. An undeclared condition could leave you paying that bill yourself.

If you think a claim has been unfairly refused, you can complain to your insurer and then escalate to the Financial Ombudsman Service, which is free to use.

How to declare a condition and find the right travel insurance

Most UK insurers use an online medical screening questionnaire when you get a quote. Follow these steps to get it right:

• Gather your details first: diagnoses, medication names and doses, and dates of recent treatment or hospital visits.
• Answer every question honestly and completely, for everyone named on the policy.
• Keep a copy of your answers and the insurer's confirmation of what is covered.
• Check the policy documents to make sure your conditions are listed as covered, not excluded.
• Update your insurer if anything changes before you travel.

If a mainstream insurer refuses cover or quotes a very high premium, don't give up. FCA rules require insurers to point customers with serious medical conditions towards specialist providers in certain situations. The government-backed MoneyHelper travel insurance directory lists firms that cover more serious conditions.

For trips to the EU, also carry a free UK Global Health Insurance Card (GHIC), or a valid EHIC. It gives you access to state healthcare on the same basis as local residents. It is not a replacement for travel insurance, as it won't cover repatriation, private treatment or cancellations.

Travel insurance vs flight delay compensation: what's the difference?

Travel insurance and flight delay compensation are two separate things, and you may be entitled to both. Your insurer pays out under the terms of your policy. Your airline owes compensation by law under UK261 (for UK flights) or EU261 (for EU flights), whatever your health or insurance situation.

You may be able to claim compensation from the airline if your flight was:

• Delayed by three hours or more on arrival at your final destination
• Cancelled with less than 14 days' notice
• Overbooked, and you were denied boarding against your will

The rules usually apply to flights departing from the UK or EU on any airline, and to flights arriving in the UK or EU on a UK or EU airline. Compensation is fixed by flight distance:

Airlines don't have to pay if the disruption was caused by extraordinary circumstances, such as severe weather or air traffic control strikes. Technical faults and staff shortages are generally not extraordinary circumstances, so many rejected claims are worth challenging.

In England and Wales you can claim for flights up to six years old (five years in Scotland), so it is worth checking past trips too.

Travelling with a health condition when your flight is delayed or cancelled

A long delay or last-minute cancellation is stressful for anyone, but it can be harder if you manage a medical condition. A few simple habits can help:

• Pack all essential medication in your hand luggage, with a few days' extra supply in case you are stuck overnight.
• Carry a copy of your prescription or a GP letter, especially for injectable or controlled medicines.
• Request special assistance from your airline at least 48 hours before you fly if you need help at the airport.
• Keep receipts for any extra costs caused by the disruption.

During a long delay, the airline also has a duty of care. Depending on the length of the delay and the flight distance, it must provide food and drink, a means of communication and, if you are delayed overnight, hotel accommodation and transfers. If your flight is cancelled, you are entitled to a full refund or a replacement flight. These rights apply on top of any compensation you are owed.

Frequently asked questions

Do I need to declare high blood pressure for travel insurance?

Usually, yes. Most UK insurers ask about high blood pressure, especially if you take medication for it. Well-controlled blood pressure often has little effect on the price.

Do I need to declare anxiety or depression?

If the insurer asks about mental health conditions, you must answer honestly. Many policies now cover mental health conditions once declared.

Does a medical condition affect my flight delay compensation?

No. UK261 and EU261 compensation depends on the flight disruption, not on your health or whether you have travel insurance.

Can I claim from my travel insurer and the airline?

Often, yes. Compensation from the airline and a travel insurance payout are separate. Check your policy, as some insurers reduce a travel delay payout if the airline has already paid you.

What if my travel insurer refuses to cover my condition?
