Does critical illness cover stroke? Yes: stroke is one of the three conditions the Association of British Insurers (ABI) requires every critical illness policy to include, though a claim is paid only when the stroke fits the policy's written definition, and the ABI's model wording, like every insurer wording on this page, leaves out a mini-stroke (TIA).
An FCA-authorised broker can check how the policies you are considering word stroke, and what each would pay; send your details using the short form and they will ring you back, free of charge.
Two tests run through every wording below: brain tissue must have died, and the effects must last, either permanently or for at least 24 hours depending on the insurer. One insurer, Vitality, also measures how disabling the stroke was and pays a share of the cover to match.
For support with a stroke or TIA, your own or a relative's, the Stroke Association runs a Stroke Support Helpline on 0303 3033 100; its lines are open 9am to 5pm on weekdays and 10am to 1pm on Saturdays.
What has to happen for a stroke claim to be paid?
The starting point is the ABI's minimum-standards guide for critical illness cover, dated 16 September 2022 and revised in April 2023. Offering cover "no less generous than the minimum standards" in it is a condition of ABI membership for members that sell critical illness insurance. Its model wording for stroke, headed "Stroke – resulting in permanent symptoms", reads (page 10):
Death of brain tissue due to inadequate blood supply or haemorrhage within the skull resulting in permanent neurological deficit with persisting clinical symptoms. For the above definition, the following are not covered: Transient ischaemic attack. Traumatic injury to brain tissue or blood vessels. Death of tissue of the optic nerve or retina / eye stroke.
Put simply, the stroke must have killed brain tissue, through a blocked blood supply or a bleed inside the skull, and left a deficit that will not go away. Head injuries, and strokes affecting the eye's optic nerve or retina, fall outside it. An ABI member may word its cover more generously than this but not less; the guide to the ABI minimum standards, one of our critical illness and income guides, explains how that works.
Two further conditions sit in the policy terms rather than the definition. Legal & General's terms (QGI14872, October 2026) require the person to survive 14 days from diagnosis, with the diagnosis made by a verified UK medical consultant whose specialism it considers appropriate; Aviva's Life Insurance+ conditions (AL50002, February 2026) set a survival period of at least 10 days. Where a wording demands permanent effects, the ABI guide says the assessment period will not normally run past 12 months once all the evidence is available.
Does critical illness cover a mini-stroke (TIA)?
Not under any wording on this page. The ABI model and the stroke definitions of Legal & General, Aviva, Royal London and Vitality each list the transient ischaemic attack as not covered. The NHS calls a TIA a "mini stroke": a brief interruption of blood flow to part of the brain whose effects fully resolve within 24 hours, so it falls short of a test of permanent symptoms or of symptoms lasting at least 24 hours.
Doctors sometimes call an event a possible TIA before tests settle what it was. If that has happened to you or a relative, the broker can talk through, free on the call-back, how a particular policy's wording would apply.
How do four insurers word their stroke definitions?
Insurers may depart from the ABI model provided they are no less generous, and the four below have.
| Insurer and document | What the stroke must leave behind |
|---|---|
| Legal & General, Policy Terms and Conditions (QGI14872, October 2026), page 31 | Symptoms that persist for at least 24 hours; no requirement that they be permanent |
| Aviva, Life Insurance+ Policy Conditions (AL50002, February 2026), page 36 | A permanent deficit, or a scan showing tissue death or a bleed together with symptoms lasting 24 hours or more |
| Royal London, definitions tool on its website for financial advisers (wording dated November 2015), read October 2026 | A scan showing tissue death or a bleed, and symptoms lasting 24 hours or more |
| Vitality, Personal Protection Plan Provisions (February 2025, from its adviser literature library, archived 21 February 2026), page 117 | Symptoms that persist for at least 24 hours, with the payment then graded by severity |
So Legal & General, Royal London and Vitality set a 24-hour test in place of the model's permanent one, and Aviva accepts either route. Royal London also requires scan evidence; its wording is dated November 2015 and comes from a site meant for advisers, so a policy document may phrase it differently. The full list of conditions is on the pages for Legal & General's critical illness policy, Royal London's critical illness policy and Vitality's Serious Illness Cover.
A wording read here shows how insurers differ, not what your own policy or an offer in front of you says. If you are weighing two or three policies, a broker can set their stroke wordings side by side for you on a free call-back; just leave your details in the form.
Is a critical illness payout for stroke the full sum, or part of it?
Usually the full sum. Under Legal & General's terms a qualifying diagnosis pays the amount of cover and the policy then ends, and Aviva's Life Insurance+ summary (AL50001, February 2026) promises "your full cover amount" after a 10-day survival. How large that sum should be is a separate decision, covered in how much critical illness cover you need.
Vitality's Serious Illness Cover is built differently. Its provisions pay "a percentage of your Serious Illness Cover between 5% and 100%" according to severity, and for stroke the severity is judged on the Modified Rankin Scale, which "is scored from 0 to 5, with 5 being the most severe", under a consultant neurologist's supervision. The stroke levels are:
- Level A (100% of cover): a residual deficit of 4 or more on the scale.
- Level B (75%): a score of at least 3.
- Level C (50%): a score of at least 2.
- Level D (25%): any stroke meeting the definition, with symptoms lasting at least 24 hours.
With 1X cover, levels A to D apply. With 2X or 3X cover the provisions say the payment for listed conditions is "increased to 100% of your cover amount", and stroke is among them. A stroke can also be re-assessed if its effects worsen. Whether other insurers make smaller payments for a less severe stroke, and the conditions attached, is a point the broker can cover for free when they phone.
Why might a stroke claim be turned down?
Because the event did not match the definition in the policy. Going by the wordings above, a claim falls outside them when the event is diagnosed as a TIA, when the damage is confined to the eye, when brain injury came from trauma (excluded in the ABI model), when symptoms did not last as long as the wording requires, when Royal London's scan evidence is missing, or when the person does not survive the 14- or 10-day period.
The answers given on the application matter too. Under the Consumer Insurance (Disclosure and Representations) Act 2012, an applicant owes the insurer reasonable care to avoid giving it a misleading answer. What to disclose when you apply explains how that works, and why critical illness claims are declined covers refusals across all conditions.
What if the stroke happened before the policy started?
Then it belongs to the application, not to a claim. Aviva's article on life insurance after a stroke (June 2026) ties a stroke claim to the policy being in force before the stroke and to the insurer's definitions being met, and says a stroke is "considered a pre-existing medical condition". Legal & General's page on pre-existing conditions says some conditions mean it cannot offer critical illness cover, while others may lead to an extra premium or to the condition being excluded, so a new policy could come with stroke left out.
Life cover has its own page, life insurance after a stroke, and critical illness cover with pre-existing conditions takes the wider question. If you would like to see what might be open to you, a broker can approach insurers, specialist ones included, once you have sent the form; nothing is promised and there is no obligation. Where an insurer has already turned you down, getting cover with a medical condition sets out other routes.
Frequently asked questions
Is a stroke considered a critical illness?
It is one of the ABI's three core conditions, with cancer and heart attack, which every critical illness policy must cover to at least the model wording. Whether a particular stroke qualifies still turns on your policy's definition. Separate pages take heart attack and cancer.
Is an eye stroke covered?
Not under the ABI model or the Legal & General, Aviva, Royal London or Vitality wordings above. Each lists death of tissue in the optic nerve or retina, the so-called eye stroke, among what its stroke definition does not cover.
Does the policy carry on after a stroke payout?
Legal & General's terms end the policy once the amount of cover is paid, and Aviva's summary says the same apart from its extra care cover. Vitality's graded system differs: each claim reduces the share of cover remaining by the percentage paid, so a 25% or 50% payment can leave cover in place.
Do insurers need a brain scan to pay a stroke claim?
Some wordings do. Royal London's asks for "definite evidence of death of tissue or haemorrhage on a brain scan", Aviva's has a route that relies on a scan, and Vitality's claim evidence may include "CT scan or MRI imaging".
When you are ready, and only if it helps, send your details through the form and a broker will go through how the policies they deal with define stroke and what each would pay, without charge.
