TL;DR: Multiple sclerosis (MS) is a pre-existing condition that must be declared on UK travel insurance applications. Cover outcomes depend on the type of MS, current disease activity, treatment complexity, and functional limitations. Relapsing-remitting MS that is well-controlled may be covered by specialist insurers with a loading; progressive or recently active MS more commonly results in exclusions or requires careful specialist underwriting. Non-disclosure is legally prohibited and can void any claim.

How UK Travel Insurers Assess Multiple Sclerosis
Multiple sclerosis is a chronic neurological condition in which the immune system attacks the myelin sheath surrounding nerve fibres, causing a range of physical and cognitive symptoms. The main types are relapsing-remitting MS (RRMS), which is characterised by periods of relapse and recovery; secondary progressive MS (SPMS), which develops in some people with RRMS over time; and primary progressive MS (PPMS), which involves a steady worsening of symptoms from onset without clear relapses. Each type carries a different underwriting profile. RRMS in full remission, managed on a disease-modifying therapy (DMT) with no recent relapse, is assessed differently from PPMS with significant functional disability or from RRMS with a relapse requiring high-dose steroid treatment in the recent past. The Association of British Insurers classifies all forms of MS as pre-existing conditions requiring disclosure (abi.org.uk). The underwriting assessment will focus on the type and stage of MS, the date and severity of the most recent relapse, current disability level, the DMT prescribed, and whether there are any complicating conditions such as bladder dysfunction, spasticity, or fatigue requiring additional management. The FCA's rules require that screening questions are clear and specific and that assessments are conducted fairly (fca.org.uk).
What to Declare When Applying for Travel Insurance With MS
Accurate and complete disclosure is essential when applying for travel insurance with MS. The Consumer Insurance (Disclosure and Representations) Act 2012 requires consumers to take reasonable care in answering all insurer questions, and misrepresentation can give an insurer grounds to reduce or reject a claim even if the omission was unintentional (legislation.gov.uk). When completing medical screening, applicants should be ready to identify the type of MS, provide the date of diagnosis, and describe the most recent relapse including its date, nature, and whether it required hospitalisation or steroid treatment. A full list of current medications must be provided, including any DMT such as interferon beta, dimethyl fumarate, natalizumab, or alemtuzumab. These treatments involve immunosuppression, which is itself an underwriting consideration. Questions about current functional status - whether the person uses a mobility aid, has bladder or bowel symptoms, or has any cognitive impairment - are standard and must be answered accurately. If there are any pending neurology appointments or MRI scans, these should also be disclosed. MoneyHelper recommends having a summary letter from a treating neurologist or MS nurse available when completing screening, to ensure all relevant clinical information is captured (moneyhelper.org.uk).
Cover Outcomes for People With MS
After declaring MS, the range of possible underwriting outcomes is wider than for many other conditions, reflecting the diversity of MS presentations. At one end, a person with well-controlled RRMS in sustained remission, on a stable first-line DMT with no recent relapses, may be offered cover by a specialist insurer - though rarely without some loading - with emergency medical cover that includes MS-related episodes. At the other end, someone with PPMS or SPMS who has significant disability, complex care needs, or who has experienced a severe relapse requiring hospitalisation in the recent past is more likely to face a specific exclusion for MS-related claims or a decline from mainstream providers. An MS exclusion in a policy typically means that emergency treatment abroad directly linked to an MS relapse, acute neurological event, or complication of MS treatment would not be covered. Unrelated medical emergencies would remain covered. The scope of exclusion wording matters: some policies exclude claims related to "any neurological condition," which is considerably broader than an MS-specific exclusion. Reading the full policy wording is essential. Consumers declined by mainstream providers should be directed to the MoneyHelper specialist directory by the insurer, as required under FCA rules (fca.org.uk).
Specialist Travel Insurers for MS and Finding the Right Policy
For most people with MS, specialist medical travel insurance providers will offer a more appropriate and reliable route to cover than standard comparison site insurers. These providers assess complex neurological profiles with more granular criteria and are more likely to offer cover that includes MS-related emergencies for stable presentations. The MoneyHelper travel insurance directory at moneyhelper.org.uk/en/everyday-money/insurance/travel-insurance-directory is the primary FCA-endorsed resource for locating these providers. When approaching a specialist insurer, applicants should be prepared to provide detailed clinical information and may be asked to submit a questionnaire or GP letter. Consumers on high-potency DMTs including natalizumab or alemtuzumab should confirm with any potential insurer whether complications or infections related to immunosuppression are covered. Annual multi-trip policies may be available from specialist providers for those who travel regularly. Comparing policies should involve not only the premium but also the maximum medical emergency cover level, whether repatriation to the UK is included, whether the policy provides a 24-hour emergency assistance line with neurological expertise, and whether any exclusion applies specifically to MS or more broadly to neurological conditions. The Financial Ombudsman Service at financial-ombudsman.org.uk is available to consumers who wish to challenge an underwriting or claims decision (financial-ombudsman.org.uk).
Practical Travel Preparation for People With MS
Beyond insurance, a number of practical considerations apply specifically to travellers with MS. Heat sensitivity (Uhthoff's phenomenon) affects many people with MS, causing a temporary worsening of symptoms in warm temperatures. Choosing cooler destinations or ensuring access to air conditioning is a relevant factor in destination planning. Long-haul air travel and fatigue management should be discussed with a treating neurologist or MS nurse before booking. A GP or specialist summary letter confirming the MS type, current treatment, and emergency contacts is advisable for all international travel, and should ideally be translated into the destination country's language. For EEA travel, a UK GHIC from nhsbsa.nhs.uk provides access to state healthcare at the local rate but does not cover all costs or repatriation. The FCDO's travel advice at gov.uk/foreign-travel-advice includes destination-specific healthcare information that may be relevant for assessing whether a country has adequate neurological care. Travellers on DMTs that require infusion or specialist administration abroad should liaise with their clinical team and the insurer's assistance line in advance to understand arrangements. Carrying sufficient medication and prescription documentation for the full trip is essential. Mobility aids and accessibility requirements should be communicated to airlines and accommodation providers in advance.

Frequently Asked Questions
Do I have to declare MS if I am currently in full remission?
Yes. Multiple sclerosis is a pre-existing condition and must be declared whenever an insurer asks about neurological or ongoing medical conditions, regardless of current remission status. The Consumer Insurance (Disclosure and Representations) Act 2012 requires consumers to answer insurer screening questions accurately. Non-disclosure can invalidate a claim even where the condition is well-controlled (legislation.gov.uk).
Will being on a high-potency disease-modifying therapy affect my ability to get cover?
It is likely to affect the underwriting assessment. High-potency DMTs such as natalizumab or alemtuzumab indicate a more active or complex disease course and involve significant immunosuppression, which is itself an underwriting risk factor. Specialist providers on the MoneyHelper directory are more likely to be equipped to assess these profiles than mainstream comparison site insurers (moneyhelper.org.uk).
What does an MS exclusion in a travel insurance policy actually mean in practice?
An MS exclusion means that emergency medical costs arising directly from an MS relapse, complication, or related treatment abroad would not be covered. Unrelated emergencies - such as a broken limb, appendicitis, or heart attack with no connection to MS - would typically still be covered. The scope of the exclusion can vary: some policies exclude all neurological conditions, which is significantly broader than an MS-specific exclusion.
I use a wheelchair due to MS - are there additional considerations for travel insurance?
Mobility aid use and functional disability level should be declared as part of the medical screening, as they are relevant to the underwriting assessment and to potential care costs abroad. Some specialist providers offer enhanced cover for mobility equipment. Airlines and accommodation providers should be notified of requirements in advance. The FCDO's travel advice at gov.uk/foreign-travel-advice may include destination-specific accessibility information.
Where should I turn if mainstream insurers have declined my MS application?
Under FCA rules, a regulated insurer that cannot offer suitable cover must direct the consumer to the MoneyHelper specialist travel insurance directory at moneyhelper.org.uk. Specialist providers there are experienced in assessing complex neurological conditions. If a claim is subsequently rejected and the consumer believes this was unfair, a complaint can be escalated to the Financial Ombudsman Service at financial-ombudsman.org.uk (fca.org.uk).
