Neurodivergent travellers warned on insurance disclosures

Neurodivergent travellers are being urged to scrutinise their holiday insurance after a surge in medical disclosures and growing concern that confusion over what to declare could leave some trips effectively uninsured.

Rising medical disclosures put focus on neurodivergent travellers

Reports from UK comparison sites and specialist brokers indicate that the number of travellers declaring medical conditions for holiday cover has risen sharply over the past two years, with some operators reporting that completed medical questionnaires have more than doubled compared with pre‑pandemic levels. Industry commentary links the increase to longer NHS waiting lists, greater awareness of autism and ADHD, and a broader push for people to disclose mental health conditions when buying financial products.

For autistic travellers, those with ADHD or people awaiting assessment, this trend is creating fresh anxiety over how much information to share. Many fear that declaring a diagnosis, or even a suspected condition under investigation, could push up premiums or trigger exclusions, while non‑disclosure could invalidate a claim.

Travel insurers frame the issue in terms of risk. Guidance from the Association of British Insurers states that customers must always declare pre‑existing medical conditions and answer all questions fully and accurately, warning that failure to do so can mean policies will not pay out if illness occurs abroad as a result of the undeclared condition.

At the same time, publicly available policy wordings show that some international medical plans explicitly exclude treatment for conditions such as ADHD and autism spectrum disorder, or categorise them within broader mental and behavioural exclusions. This mix of mandatory disclosure and limited cover is at the heart of current concerns for neurodivergent travellers.

Confusion over what needs to be declared

A key challenge is that different insurers draw the line in different places. Some require customers to disclose any condition for which they have seen a medical professional within the last two to five years, while others focus on diagnoses, hospital admissions or changes in prescribed medication. One major UK travel brand, Admiral, states in its public guidance that customers should declare anything they have seen a medical expert for in the past two years, with longer look‑back periods for certain conditions.

For neurodivergent people, that can raise questions about whether an assessment referral, a screening appointment or a note on a GP file counts as a “condition” that must be declared. Online discussions show many travellers unsure whether simply being on a waiting list for an autism or ADHD assessment needs to be disclosed, particularly if they have no related medication or history of crisis care.

Current industry guidance does not provide a single, definitive answer. The ABI notes that insurers will set out which conditions, and over what timeframe, must be declared, and advises customers to check the wording carefully and contact the insurer if unsure. Consumer advocates stress that declarations must match the questions asked. If a policy only refers to diagnosed conditions or hospital treatment, a pending referral may not fall within that definition, but where questions cover any investigations, symptoms or specialist appointments, travellers may be expected to disclose more.

Legal and financial commentators caution that non‑disclosure can have consequences even when a later claim is unrelated to the undeclared condition, if the insurer can argue that the information would have changed its decision to offer cover or its price. That risk is pushing more neurodivergent travellers to err on the side of over‑disclosure, adding to the spike in declarations.

Access to cover and the role of specialist insurers

Despite the heightened scrutiny, current evidence does not show a blanket move by mainstream UK insurers to refuse cover to autistic or ADHD travellers. The UK travel insurance market remains highly competitive, and the ABI states that cover is generally available for many pre‑existing medical conditions, although some customers may be referred to specialist providers.

Several travel insurance brands now advertise products tailored for autism, ADHD and other mental health conditions. One UK‑based specialist, AllClear Travel, highlights that it will consider cover for autism, including cases where travellers also have ADHD, provided the conditions are disclosed during screening. In many instances, surcharges reflect the potential cost of medical treatment or trip cancellation if support needs mean a holiday has to be cut short.

Regulators have also sought to improve access. The Financial Conduct Authority has introduced “signposting” rules requiring firms that cannot offer affordable cover due to serious pre‑existing conditions to direct customers towards a directory of specialist providers. A review of these rules, published in April 2024, reported that most firms were complying, although awareness among consumers remained patchy.

Advocacy groups argue that, while these measures have helped some travellers secure cover, they do not fully address the practical barriers neurodivergent customers face, such as navigating complex online questionnaires or dealing with long telephone screenings that can be overwhelming for some autistic people.

Industry moves on autism and mental health

Parts of the insurance sector have begun to respond to these concerns. In April 2024, the ABI published a good practice guide on supporting autistic customers, developed in collaboration with autism organisations and industry members. The document highlights communication barriers, sensory issues and decision‑making challenges that autistic people may face when dealing with insurers, and encourages clearer language, flexible communication channels and staff training.

This work builds on earlier mental health initiatives. An implementation report on the industry’s Mental Health and Insurance Standards, released by the ABI, noted a shift over the past decade from blanket mental health exclusions in travel insurance towards more bespoke underwriting, although gaps in coverage and understanding remain, particularly for conditions that sit between mental health and neurodevelopmental categories.

Public policy reviews in the UK, including the Buckland Review of Autism Employment and a more recent interim review into mental health conditions, ADHD and autism, have also drawn attention to low disclosure rates in the workplace and in financial services more broadly. Analysts say similar dynamics are likely playing out in travel insurance, where fear of stigma or financial penalty may deter some people from declaring their neurodivergent status.

Campaigners are calling for clearer, standardised questions around neurodevelopmental conditions in travel insurance forms, alongside explicit explanations of what is and is not covered when such conditions are declared.

Practical steps for neurodivergent travellers

Health agencies and travel medicine specialists advise all travellers to consider both medical treatment cover and medical evacuation insurance when going abroad. Guidance from the US Centers for Disease Control and Prevention recommends that people check carefully whether policies include or exclude mental health and psychiatric emergencies, as well as any limits on cover linked to pre‑existing conditions.

For neurodivergent travellers, consumer advocates suggest several practical steps before booking. These include reading the medical declaration questions in full, confirming whether autism, ADHD or related conditions are classified as mental health or neurological for the purposes of the policy, and keeping written records of any disclosures made during telephone screenings or online forms.

Where mainstream providers decline to cover a disclosed condition or quote unaffordable premiums, travellers can use specialist medical travel insurance directories signposted by regulators or industry bodies. These services list insurers that are willing to underwrite higher‑risk or less common conditions, often with clearer wording around what support and treatment are included.

With summer booking season approaching and medical declarations on the rise, experts say the key message for neurodivergent travellers is that uncertainty should not be left unresolved. Clarity over what to declare, and how cover will respond if plans change due to a neurodivergent condition, is increasingly vital if holidays are to be protected rather than put at risk.
