Neurodivergent travellers face new warning on insurance

Neurodivergent travellers are being urged to review their holiday cover after fresh UK data and consumer research indicated a sharp rise in medical declarations for conditions such as ADHD and autism, alongside growing confusion over what must be disclosed to keep travel insurance valid.

Declarations surge as more conditions are disclosed

Recent data and insurer commentary in the UK indicate that medical declarations linked to neurodivergent conditions and broader mental health issues have risen significantly over the past year, with some providers reporting that disclosures for ADHD and autism have at least doubled compared with pre‑pandemic levels. While individual insurers publish figures in different formats, consumer research released by major providers shows many more travellers now listing mental health and neurodevelopmental diagnoses when buying cover, rather than limiting declarations to physical illnesses.

At the same time, industry surveys highlight a persistent gap in awareness. Research cited by Co‑op Insurance in late 2025 suggested that more than 16 million UK adults did not realise that failing to disclose an undiagnosed but investigated health issue could invalidate their travel insurance, potentially leaving them exposed to medical bills abroad. The findings are particularly relevant for neurodivergent people on long NHS waiting lists for ADHD or autism assessments, or those undergoing wider mental health investigations.

Reports from mainstream providers such as Admiral underline how far confusion extends. In a 2024 survey of UK holidaymakers, a notable share of respondents said they would not declare antidepressant use or ADHD medication when taking out a policy, despite both being treated as medical conditions by most insurers. Consumer advocates say this mismatch between traveller assumptions and policy wording raises the risk that neurodivergent holidaymakers will either pay for cover that does not protect them as expected or travel without any effective medical protection at all.

Specialist insurers serving neurodivergent customers report that more travellers are seeking tailored policies that explicitly list conditions such as autism and ADHD. These products often require detailed medical screening but aim to provide clarity on what is covered if a diagnosis contributes to a claim, for example if a change in treatment affects the ability to travel or a behavioural episode leads to emergency care abroad.

Undiagnosed and “awaiting assessment” cases create grey areas

One of the fastest‑growing pressure points involves travellers who have not yet received a formal diagnosis but are on waiting lists or undergoing investigations. Guidance from UK financial and consumer bodies indicates that many insurers treat “awaiting investigation” status as a material fact that must be disclosed, even if the suspected condition is neurodevelopmental rather than physical. This includes people awaiting assessment for ADHD or autism, where the outcome may not alter day‑to‑day health risks but is still considered relevant by underwriters.

Consumer advice organisations note that this can leave neurodivergent travellers in a difficult position. Some mainstream insurers decline to cover anyone awaiting investigation for a mental health or neurological condition, or will only quote via a referral to a specialist medical insurer. In other cases, cover is offered but with explicit exclusions for any claim linked to the undiagnosed issue, which can be hard to interpret in real‑world situations.

Publicly available information from MoneyHelper and disability charities explains that policyholders are usually required to declare both confirmed diagnoses and ongoing investigations. If a traveller answers “no” to medical questions while on a waiting list, an insurer may later argue that the non‑disclosure was significant, even if the eventual claim is not obviously connected to the suspected condition. For neurodivergent people whose assessments have been delayed for months or years, that risk is increasingly hard to ignore.

Meanwhile, travel insurance complaints to the UK Financial Ombudsman Service have climbed to their highest level since the pandemic, with a portion of disputes relating to medical disclosure. Case summaries published by the ombudsman stress that policies can be voided where an insurer can show that a reasonable person would have considered a non‑disclosed investigation or diagnosis important when buying cover.

Rules and signposting for travellers with complex conditions

Regulators have tried to improve access to travel cover for people with pre‑existing medical conditions, including mental health and neurological issues. The UK Financial Conduct Authority introduced “signposting” rules requiring insurers to direct customers with serious medical conditions to a specialist directory if they cannot offer affordable cover themselves, or if a quote includes a high medical loading. A post‑implementation review published in 2024 found that these measures have helped some vulnerable customers find suitable policies, but also that travellers with complex health profiles still face higher premiums and refusals.

Industry standards developed through the Association of British Insurers have also pushed insurers to be clearer about how mental health and related conditions are assessed. Implementation reports suggest progress in areas such as making application questions easier to understand and avoiding blanket exclusions for all mental health diagnoses. However, campaigners for neurodivergent people argue that assessment tools still tend to group diverse conditions together, and may not reflect the different risk profiles of, for example, a stable autism diagnosis compared with a recently hospitalised psychiatric condition.

Government travel guidance issued via official channels in the UK advises all travellers to declare any existing physical or mental health condition and to read policy terms closely, including sections on exclusions and medical screening. The guidance emphasises that treatment for undeclared pre‑existing conditions is a common area of dispute when holiday plans go wrong, and that travellers with serious or complex health needs may benefit from specialist providers listed on regulated directories.

For insurers, neurodivergent travellers are part of a wider push to recalibrate how risk is priced for non‑standard customers. Industry reviews highlight that consumers with one or more vulnerability characteristics, such as long‑term mental health problems or cognitive conditions, are still less likely to obtain cover that fully reflects their medical needs. The rapid growth in declarations of ADHD and autism is prompting some providers to develop more granular underwriting models, though these approaches remain uneven across the market.

Practical implications for neurodivergent holidaymakers

For travellers, the immediate concern is what the shift in declarations means in practice. Consumer advocates say the first step is to assume that neurodivergent and mental health conditions must be disclosed if asked about medical history, whether or not they are actively causing problems. This includes long‑standing diagnoses of autism or ADHD, as well as related issues such as anxiety or depression that might be recorded with a general practitioner.

Where a traveller is awaiting assessment or recently referred for investigation, publicly available guidance recommends stating this clearly during medical screening, even if it increases the premium or leads to a referral to specialist insurers. While this can mean higher up‑front costs, it substantially reduces the risk of a claim being rejected on the basis of non‑disclosure. Specialist providers offering autism or ADHD travel insurance typically allow customers to list multiple conditions and medications, and then specify in writing what is covered.

Neurodivergent travellers are also encouraged by advice agencies to consider how their condition might interact with the logistics of their trip. For example, sudden changes in routine, sensory overload or difficulties with executive functioning can affect the likelihood of missed flights, lost medication or the need for support services abroad. Choosing a policy with robust cover for missed departures, medical emergencies and repatriation can be particularly important for those who know that travel environments can exacerbate stress or overwhelm.

At the same time, UK disability and money guidance sites stress that the European or UK Global Health Insurance Card is not a substitute for travel insurance, as it does not cover private treatment, repatriation or non‑medical losses such as cancellation. For neurodivergent holidaymakers, relying solely on public healthcare access overseas can leave significant gaps if, for example, a behavioural crisis results in private clinic involvement or extended accommodation costs.

Calls for clearer language and fairer pricing

As declarations of neurodivergent conditions rise, advocacy groups and financial campaigners are calling for simpler policy language and more consistent treatment of mental and neurological health across the travel insurance market. They argue that current medical questionnaires often blur distinctions between developmental conditions and acute psychiatric episodes, and that travellers are left guessing whether stable neurodivergent diagnoses really increase risk or are being used as a blunt pricing tool.

Regulatory reviews already under way are examining how insurers communicate with customers who may have cognitive differences, including autistic people or those with ADHD who struggle with long, densely worded documents. Proposals discussed in public documents include shorter medical questionnaires, clearer examples of what counts as a pre‑existing condition and more use of signposting to regulated advice services where customers are unsure how to answer.

For now, publicly available guidance converges on a cautious approach: declare more rather than less, keep written records of information given to insurers, and seek out providers willing to give explicit confirmation of cover for specified neurodivergent and mental health conditions. With medical declarations for these conditions growing rapidly, the way insurers respond is likely to shape whether future holidaymakers on the autism and ADHD spectrums feel confident that their trips are properly protected.
