Parkinson's disease is a named condition on many critical illness policies, so critical illness cover can pay out for it, but the standard wording asks for permanent impairment of movement rather than a diagnosis alone. It also sets aside other conditions that look like Parkinson's.
Policies word Parkinson's differently, and an FCA-authorised broker can read each definition with you. There is no charge for the call-back, and the request is made on the form on this page.
What follows sets out what the standard wording asks for and where insurers' own versions differ. Someone who already has the diagnosis and wants life cover will find that on the page about life insurance with Parkinson's disease.
Does a Parkinson's diagnosis alone meet the definition?
Not under the model wording. The Association of British Insurers (ABI) sets it out at 4.2.16 of its minimum-standards guide (page 14 of 36):
Parkinson’s disease [before age x] – resulting in permanent symptoms A definite diagnosis of Parkinson’s disease [before age x] by a Consultant Neurologist or Consultant Geriatrician. There must be permanent clinical impairment of motor function with associated tremor and muscle rigidity. For the above definition, the following are not covered: • Parkinsonian syndromes/Parkinsonism.
Three tests apply together. A named kind of consultant has to make the diagnosis, the impairment of movement has to be permanent, and it has to come with tremor and muscle rigidity. Each is a condition of the claim, so a diagnosis on its own does not meet the wording.
The phrase "permanent symptoms" is part of the heading and the test, not a figure of speech. Parkinson's UK describes Parkinson's as "a progressive neurological condition", with tremor, slowness of movement and rigidity as its three main symptoms. In the ABI guide, permanent means "Expected to last throughout the insured person’s life, irrespective of when the cover ends or the insured person retires" (glossary, page 30 of 36), so the question is whether the loss of movement is expected to last, not only whether symptoms are present.
The same diagnosis can therefore be a different matter on the day it is made and some time later. A claim for permanent disability is a different benefit with its own test, and that is set out separately.
Tremor and rigidity, or tremor or rigidity?
Small word choices change what a claim has to show. These are the definitions as the documents print them, set against the ABI model.
| Document | Who diagnoses | What the impairment must come with |
|---|---|---|
| ABI model wording (2022, updated 2023) | Consultant neurologist or consultant geriatrician | Tremor and muscle rigidity |
| Legal & General policy terms (QGI14872, October 2026) | Consultant neurologist or consultant geriatrician | Tremor or muscle rigidity |
| Royal London plan details (July 2025) | Consultant neurologist or geriatrician | Either tremor or muscle rigidity |
| Aviva Life Insurance+ policy conditions (AL50002, February 2026) | Consultant neurologist or geriatrician | Tremor or muscle rigidity |
| Vitality plan provisions (February 2025), permanent-symptoms version | Consultant neurologist | Tremor and muscle rigidity |
A wording that needs either tremor or rigidity asks for less than one that needs both, so the same set of symptoms could sit differently against two policies. Whether a particular diagnosis would be accepted is for the insurer to decide on the claim.
Vitality's provisions also set out a second, plainer version: a definite diagnosis by a consultant neurologist "with evidence of current or previous symptoms (these symptoms do not need to be permanent)". Which version a given plan carries is something to check in that plan's own documents. Vitality arranges some of its conditions by severity level, which the page on severity-based cover describes.
Ask the broker who rings after the form on this page to set the Parkinson's wordings of the policies you are weighing up alongside each other, including how each would treat early symptoms.
Which policies list Parkinson's?
Parkinson's is not one of the three conditions, cancer, heart attack and stroke, that the ABI requires every policy to cover. It sits in a later chapter of the guide, which says insurers may leave out any of the conditions there, but where they include one they "must use that model wording" (page 11 of 36).
In practice, many insurers do list it. Legal & General's policy terms (October 2026), Royal London's plan details (July 2025), Vitality's plan provisions (February 2025 edition) and Aviva's Life Insurance+ conditions (February 2026) all contain a Parkinson's definition. Whether a policy you are looking at does is shown in its list of conditions; the page on which conditions policies cover explains how to read one, and the ABI minimum standards are covered in their own guide.
Parkinsonism, drug-induced parkinsonism and Parkinson-plus syndromes
Every definition above ends with the same carve-out: "Parkinsonian syndromes/Parkinsonism" in the ABI wording, with Legal & General adding "other". The ABI's glossary defines parkinsonian syndromes as "Conditions that are not primary Parkinson’s disease but which exhibit the same symptoms" (page 29 of 36).
Parkinson's UK explains that parkinsonism is a term covering "several conditions", Parkinson's among them, and names three main forms: idiopathic Parkinson's, vascular parkinsonism and drug-induced parkinsonism. None of the wordings quoted here names a cause or a form; they rely on the ABI's test of whether the condition is primary Parkinson's disease, and how that applies to a particular diagnosis is for the insurer to decide on the claim. Where the diagnosis is vascular or drug-induced parkinsonism, the broker who rings you can go through how a policy words this exclusion, at no cost.
Some policies give related conditions an entry of their own. Royal London's plan details list "Parkinson plus syndromes", naming multiple system atrophy, progressive supranuclear palsy, parkinsonism-dementia-amyotrophic lateral sclerosis complex, corticobasal ganglionic degeneration and diffuse Lewy body disease, with a separate test of permanent impairment. Vitality has a similar entry, and Aviva's Life Insurance+ conditions include Parkinson's plus syndromes only under upgraded critical illness benefit, chosen at extra cost. Aviva's older Critical Illness Plan conditions (May 2023 edition) differ: their Parkinson's definition needs both tremor and rigidity and itself takes in corticobasal degeneration and diffuse Lewy body disease.
Applying for cover once Parkinson's is diagnosed
If the diagnosis is recent, Parkinson's UK's helpline and advisers can answer questions about the condition itself on 0808 800 0303.
For cover, a diagnosis you already have is something an insurer asks about at application. Whether it can offer critical illness cover, and on what terms, differs by insurer. The page on pre-existing conditions explains the usual outcomes, the rules on disclosure cover what you must tell an insurer, and the guide to being declined covers next steps. Life insurance with medical conditions gives the wider picture.
A broker can approach specialist insurers about your case. If you want a broker to ask them, use the form on this page, although cover can never be promised.
Frequently asked questions
Is Parkinson's disease a critical illness?
On many policies, yes, but it depends on the list in the policy you hold or are looking at. It is not one of the three conditions every policy must include. Another neurological condition with its own wording is covered in the page on multiple sclerosis.
Do Parkinson's definitions carry an age limit?
Not in the Legal & General, Royal London, Aviva or Vitality wordings in the table, none of which prints an age. The ABI heading's "[before age x]" is optional: insurers may use model wordings with "specified optional age limits" included or left out (page 7 of 36). Aviva's Life Insurance+ extra care cover is a separate benefit that accepts a Parkinson's claim only for a life covered under age 55, set out on the page on dementia and critical illness.
What happens to an Aviva policy after a Parkinson's claim?
Aviva's Life Insurance+ conditions say that once a critical illness claim is accepted, the policy will end, unless extra care cover was chosen and the life covered can claim under it. Other insurers' terms differ, so the policy documents are the place to check, and how critical illness cover works sets out the general picture.
