You can sometimes get life insurance on a sick parent, but not on your own: Legal & General, for one, says you need an insurable interest in your parent and their consent, and has the parent fill in the application. A diagnosis can change what an insurer offers, though it does not always rule cover out.
If your parent is living with a terminal illness, Marie Curie offers free information and support on terminal illness, dying and bereavement; its number is 0800 090 2309. For cancer, Macmillan's Support Line (free and confidential, for people living with cancer, family and friends) is 0808 808 00 00, 8am to 8pm, 7 days a week.
Some over-50s plans ask no health questions at all, though a death from illness in their first year returns only the premiums paid; the three compared further down set out those terms.
If you and your parent want to know what might be open to them, an FCA-authorised broker could go through it by phone. Arranging that call takes a short form on this page, and neither of you pays anything for it.
What do insurable interest and consent mean when a parent is unwell?
Legal & General's guide (9 March 2026) says you can insure a parent only where you have an insurable interest in them: you would have to show an insurer that their death would leave you in financial hardship, struggling to meet their financial obligations. Two of its examples fit a parent who is unwell: debts or medical bills that the children must repay, and care costs that fall on a surviving parent.
On consent, the same guide says "the parents must consent before life insurance can be taken out on their behalf", and Legal & General's own application has to be completed by the person being insured. That puts the health questions in your parent's hands, and it is there that an illness counts. Other insurers set their own application process, so ask each one how it handles a parent's consent. The law behind insurable interest, and what happens if you buy on someone without one, are on life insurance for parents; other relationships are on life insurance on someone else.
How does a serious diagnosis change a new application?
Aviva's guide to pre-existing conditions (last updated 7 January 2025) says a pre-existing condition need not stop someone getting cover, but the insurer may want more evidence before deciding: Aviva lists a doctor's report, a phone call with a nurse, a mini screening or an examination. A serious, long-term condition may lift the premium, and in some cases cover is not offered at all, in which case Aviva says you may find it elsewhere.
On its own pre-existing conditions page (16 March 2026), Legal & General says every individual is different, that it needs the applicant's consent before it asks their doctor for a report, and warns that a future claim may not be paid if the health information given when applying was not full and accurate. For a parent, that means the answers have to be theirs, and complete. What you must tell a life insurer is on pre-existing conditions and non-disclosure, and the wider picture is on life insurance with medical conditions.
Which over-50s plans ask no health questions, and what are the waiting terms?
Guaranteed-acceptance plans skip the health questions, which is why they come up when a parent is unwell. Each insurer states its own terms:
| Plan | Who is accepted | Death in the first year | Premiums stop |
|---|---|---|---|
| Legal & General Over 50s Fixed Life Insurance (QGI12836 11/2025, direct) | Ages 50 to 80, UK resident, no medical questions | Premiums refunded; full cover if the death is accidental | At age 90 |
| SunLife Guaranteed Over 50 Plan (S-G050T12.25.V3) | Ages 49-85, UK resident | All premiums refunded, unless the death is the result of an accident as the terms define it | Policy anniversary on or after the 95th birthday |
| Aviva Over 50s Life Insurance (WC05649 09/2026) | Ages 50 to 80, UK resident, no health questions or medical | A sum equal to the premiums paid, unless the death is an accident, when the cover amount is paid | After 30 years or the anniversary after the 90th birthday, whichever comes first |
Put plainly, at all three a death from illness in the first year returns the premiums paid, not the cover amount. All three also say the cash sum is fixed and that inflation will reduce what it buys, and they say you could pay more in total than the payout: Aviva puts it as the payout possibly being lower than the premiums paid, depending on how long you live. Because each plan is aimed at funeral-sized sums, how much they pay is on funeral cover limits, and the plan-by-plan detail is on the best life insurance over 50.
If it would help to weigh one of these against your parent's situation, the broker who rings back after the form on this page can talk it through, free of charge.
What about a parent who is terminally ill, or who already has a policy?
Where there is no policy yet, the question for a new application is whether the insurer would consider someone with a terminal diagnosis at all, and on what terms. That is worth asking an insurer, or a broker, before your parent applies; life insurance with a terminal illness covers that case.
If your parent already holds a policy, its terms may pay something now. Aviva's cancer guide (last updated 12 May 2026) says that with Aviva, "if you’re diagnosed with a terminal illness that meets our policy definition, and you’re not expected to live longer than 12 months we’ll pay out the value of your policy", but "we won't be able to pay out if your doctor thinks you might live longer or there is treatment that could extend your life". That is one insurer's wording; another policy may differ, so the insurer that issued it is the one to ask. Terminal illness benefit explains how the feature usually works.
Cancer, dementia, HIV or a disability: does the condition matter?
Keep the stages of cancer apart. Macmillan says people usually have to tell insurers about cancer, and that during tests or treatment an insurer might refuse cover straight away, though it may agree to look at the application again once the diagnosis is known or treatment has finished. After treatment, Aviva says, many providers won't offer cover until at least a year has passed since the last treatment. Macmillan adds that an insurer may turn an application down or charge more because of cancer, but only where it has evidence the person is more likely to claim. Cover during treatment, after treatment and for terminal cancer are three different questions; see life insurance while you have cancer and life insurance after cancer.
For HIV, there is a page of its own on life insurance with HIV, and dementia as a critical illness is on critical illness cover and dementia. How an insurer would treat dementia, a disability or any other condition on a parent's application depends on the insurer and the details, and a broker can talk that through with you, free of charge, on the call-back.
Frequently asked questions
Can a parent with dementia take out life insurance?
Legal & General's application must be completed by the person being insured. Whether another person could act for a parent who cannot manage this is for the insurer to say, and a broker can ask on your behalf.
Would an over-50s plan pay if my parent died of an illness they already had?
After the first 12 months, Aviva says it pays the cover amount if the policyholder dies for any reason, and Legal & General's summary describes a cash sum paid on death once the first year is over. Within the first year, a death that is not an accident returns the premiums paid instead, as the table above shows.
What if my parent is turned down for cover?
A decline from one insurer does not always end the options, since Aviva says you may be able to get life insurance elsewhere. Life insurance declined or postponed sets out the next steps.
Whatever you decide, the choice stays with you and your parent. Should you want a broker to look at cover for them, filling in the form here is the first step, and the conversation that follows costs nothing.
