If you’re planning a trip to the UK, you might have heard about a health declaration and wondered whether you need to fill one in. Since the end of the pandemic-era passenger locator forms in 2022, the UK has moved to a different system. For most visitors, the key step is now the Electronic Travel Authorisation (ETA), which costs £16 per person and is processed in minutes. The important thing to know is that the ETA application does not ask any health or vaccination questions. That means no health declaration is required for the vast majority of short-term visitors.

That said, the picture changes if you’re applying for a longer-term visa, planning to use the NHS, or buying travel insurance. Each of those situations involves its own kind of health information, and getting it wrong can cost you money or cause delays. Here’s what you actually need to know.
What the ETA Covers and What It Doesn’t
The central concept here is the health declaration — a formal statement about your medical history, current health, or vaccination status. In the UK travel context, this used to be part of the passenger locator form during the pandemic. That requirement ended in 2022, and the new ETA system deliberately excludes health screening.
What I tend to notice is that people confuse the ETA with older visa processes that did ask health questions. If you’re a short-term visitor from a visa-waiver country, you don’t need to prepare any medical documents for entry.
When You Actually Need to Declare Your Health
While the ETA doesn’t ask about health, other parts of your trip might. The most common situations are visa applications for stays longer than six months, private health insurance, and NHS treatment. Each has different rules and different consequences for getting it wrong.
For visa applications that do require health information, you’ll typically need to complete a medical questionnaire and may need a tuberculosis test depending on your country of residence. The Home Office uses this to assess whether you’re likely to place a significant burden on the NHS. The threshold is high — most routine conditions won’t trigger a refusal — but failing to declare something that later comes to light can lead to a visa being cancelled.
Private health insurance is a different matter. If you’re buying a policy for your trip, you’ll be asked about pre-existing conditions. The key distinction here is between conditions that are stable and those that require ongoing treatment. Most insurers will exclude pre-existing conditions unless you declare them and pay a higher premium. A health insurance policy for pre-existing conditions can cover you, but only if you’re upfront from the start.
NHS treatment for visitors is not free across the board. Some services, like A&E, are free to everyone. But planned treatment, hospital stays, and specialist care may incur charges. The NHS website makes clear that visitors are not automatically entitled to free care. If you need treatment, you’ll be asked about your immigration status and may be billed. This is where having travel insurance that covers medical expenses becomes important.
Common Mistakes People Make With Health Declarations
Assuming the ETA requires health information
The most common error is preparing medical documents for an ETA application that doesn’t ask for them. The form asks for your name, passport details, and a few suitability questions about criminal history and previous immigration breaches. That’s it. No vaccination records, no COVID test results, no medical history. If a website asks for health information during an ETA application, it’s either a scam or an unnecessary third-party service. The official UK government ETA guidance confirms this.
Not declaring pre-existing conditions on travel insurance
This is the most financially costly mistake. If you have a condition like asthma, diabetes, or high blood pressure and don’t declare it, your insurer can refuse to pay out if you need treatment related to that condition. A routine hospital visit for a diabetic episode could leave you with a bill running into thousands of pounds. The fix is straightforward: declare everything when you buy the policy. Some insurers specialise in covering pre-existing conditions, and the premium difference is often smaller than people expect.
Assuming NHS care is free for all visitors
Many visitors assume the NHS is free for everyone. It isn’t. While A&E and some GP services are free, hospital admissions, outpatient appointments, and surgeries can be charged. The NHS charges visitors at 150% of the standard NHS rate for most treatments. If you’re from a country without a reciprocal healthcare agreement, you could be billed for the full cost. The NHS visitor guidance explains what’s covered and what isn’t.
Using unofficial websites for the ETA
Scam sites often charge inflated fees and may ask for unnecessary health information. The official ETA costs £16 and is processed through gov.uk. Any site asking for more or requesting medical details should be treated with suspicion. If you’ve used a third-party site, you may have paid extra for no benefit and shared personal data unnecessarily.
How to Handle Health Information for Your UK Trip
Applying for the ETA
The process is straightforward and entirely online. You’ll need your passport, a credit or debit card, and access to email. The form takes about 10 minutes. You answer identity questions and a few suitability checks. No health information is requested. Once approved, the ETA is linked to your passport electronically for two years or until your passport expires. There’s no need to print anything.
Buying travel insurance
This is where health information matters most. When you apply for a policy, you’ll be asked about pre-existing conditions. Be honest and thorough. If you’re unsure whether a condition counts, declare it anyway. The insurer will tell you if it affects your cover. A good travel insurance policy should cover emergency medical treatment, repatriation, and cancellation due to illness. For those with ongoing conditions, it’s worth looking at whether private health insurance is worth it in the UK for longer stays.
Planning for NHS use
If you think you might need NHS treatment during your stay, check whether your home country has a reciprocal healthcare agreement with the UK. If it does, you may be entitled to some free treatment. If not, make sure your travel insurance covers medical expenses. For planned treatment, you’ll need to pay upfront or have private insurance that covers it. The NHS will ask for proof of your immigration status and may request payment before treatment begins for non-emergency care.
Future changes to watch
The UK government has indicated that the ETA system may expand in scope over time. As of 2026, no health declaration is planned, but the system is still relatively new — it launched for non-European nationals in January 2025 and for European nationals in April 2025. Any changes to health requirements would be announced on gov.uk. It’s worth checking the official guidance before each trip rather than assuming the rules haven’t changed.

What This Means for Your Next Trip
The absence of a health declaration from the UK ETA is a genuine simplification for most visitors. But it doesn’t remove the need to think about health cover. The gap between what the government asks and what you actually need for a safe trip is where people get caught out. Travel insurance, pre-existing condition declarations, and understanding NHS charging rules are all your responsibility, not the government’s.
