Whether you can cancel, and what leaving costs you, is set by your own policy wording. Aviva's and Vitality's cancellation clauses both let a policyholder end cover before the year is out, each on its own terms. Most of what people want settled first, such as how long the cooling off period lasts, how much notice to give, whether any premium comes back and what happens to treatment under way, depends on the policy, so this page sets those out as questions for your insurer, in the order they arise. If another policy is to replace this one, settle it before you give notice, because a new insurer may assess your medical history afresh. Before that, an FCA-authorised broker can show your current terms to a number of insurers; asking for that introduction through the enquiry form here is free, and going straight to an insurer is the other route.
Cancel private health insurance: what two insurers' wording says
Notice, fees and refunds can differ between insurers and between products, and each of the two clauses below is one rule from a long document, not the whole picture. The first is from Aviva's terms:
"After the cooling off period The policyholder may cancel the policy after the cooling off period, but we will not refund any premiums that have been paid for cover up to the cancellation date"
— Aviva, Healthier Solutions Terms and conditions (April 2025 issue), page 33 of the PDF (numbered 31 in print), read 4 September 2026. Aviva has since published a March 2026 issue, so read this as the April 2025 version, check the edition in your own pack, or put the question to the broker when they call.
Two things follow from the words. The clause names a cooling off period and treats cancelling after it as a separate case; its length depends on the policy, so look for it in your own documents. And on money it settles one point: premiums for cover already received are not refunded. The sentence does not deal with premiums paid for a period still to come, which matters if you pay annually in one sum, so that is a question to put to Aviva rather than an answer either way.
The second clause is Vitality's. Its Membership Guide for the Personal Healthcare plan (August 2024 issue, page 37, captured 10 October 2026 from a copy published by a third party) reserves the right to charge an administration fee of £40 if you cancel before the end of the 12 month term the plan covers. The exact sentence, and what it leaves open, are on the page on cancelling Vitality health insurance.
Neither clause is a rule about the market. Each belongs to one insurer's wording and tells you nothing about what Bupa, AXA, The Exeter or anyone else would do: a fee in one policy may be absent from another, and the reverse. If your insurer is not one of these two, the questions further down are how you fill the gap.
Cancelling part-way through the year, or at renewal
Cover on a personal policy is normally bought a policy year at a time, and the two exits are not alike.
At renewal. The year has ended, nothing is half-used, and the next year's price is in front of you, so this is the usual exit. Whether cover carries on unless you say otherwise, and by when you must say so, are for your own wording or your insurer to confirm. Where to find that date, and what to ask about it, are on the renewal period page. If the reason you are thinking of leaving is the price, the renewal price page covers what you could change while staying.
Part-way through. This is where the two clauses bite. Both contemplate a policyholder leaving early, and each attaches a cost: Aviva's keeps premiums for cover already provided, and Vitality's reserves a fee. For any other insurer the cost, if there is one, is set by its own wording. Find your policy start and end dates on the schedule, then ask whether leaving on a given day would cost you a fee, a refund you will not see, or paid-for cover you will not use; a broker can talk you through those terms on a free call-back.
What happens if you cancel: refunds, fees and claims
On refunds, the Aviva clause says what is not returned, not what is, and whether unused months come back pro rata depends on the policy. So do not budget for one, and do not rule it out: ask. Whether a monthly payer's cover ends with the last payment, and what an annual payer gets back, are both for your insurer to say.
Three further matters turn on the policy, and each is a question to put before giving notice:
- Can I cancel my health insurance after a claim? Whether a past claim changes anything depends on the policy. What matters more is treatment already authorised or under way: does cover for it stop on the cancellation date, or is it finished? Ask before the date, not after.
- Is stopping the direct debit the same as giving notice? A bank instruction is not necessarily notice of cancellation. Whether your insurer accepts it as such, and how it treats a premium that goes unpaid, is its to say.
- What if I want cover again later? Buying again is a new application, and how an insurer treats a returning customer is its own call, so assume your history would be assessed again.
That last point is why "should I cancel my private health insurance" rarely has a one-line answer. Going without leaves you to the NHS for anything that arises, and a fresh policy later may exclude conditions that arose in the meantime. What you give up depends on your health, your budget and the policy in question, and your insurer or a broker can set out the facts for yours.
How to cancel private medical insurance, in order
If anything is to follow the old policy, the sequence matters more than the speed. Moving without a gap, and what carries across to a new insurer, are covered on the page on switching insurer; these are the steps for the policy you are leaving.
- Find the dates. Your schedule or membership certificate shows when the year started and when it ends. Everything else is measured from those.
- Read the cancellation section of your wording. It may be headed cancellation, ending cover or policy term. If you cannot find it, ask which clause applies and request the answer in writing.
- Ask about the cooling off period if you took the policy out recently: how long it is, and whether it still applies to you.
- If a replacement is coming, have its terms and start date agreed in writing first. A new insurer that reads your history from scratch may leave out the condition you most wanted covered; the page on pre-existing conditions sets out how insurers' wordings treat them.
- Give notice in the way your wording or your insurer requires, and keep a copy of what you sent and when.
Step four is where a broker earns its place. It can ask the insurers on its panel, in one round, whether each would carry your existing terms across, while your current policy is still running. That panel is not the whole market, and no lower price is promised.
Cancelling group or company health insurance
If your cover comes through an employer, the policy is in general the employer's, and you are a member of the scheme rather than the policyholder. Whether a member may leave a scheme, when, and what happens to their cover if they do, depends on the scheme. Ask whoever administers the scheme at work whether membership is optional and how it is ended.
Before acting, check what you could buy afterwards. A policy of your own is written on its own terms, and the basis you are leaving may be kinder than what an individual is offered; once they ring, a broker can explain, at no charge, how a personal policy would treat your history. How tax applies to employer-paid cover is a separate subject from cancelling, and is set out on the page on health insurance and tax.
A group health insurance cancellation letter, if one is needed, takes whatever form your employer's scheme asks for. For a personal policy, your insurer will say whether it accepts notice by letter, phone or online, and what details it needs, such as your policy number and the date you want cover to end.
Cancelling private health insurance: short answers
Can I cancel private health insurance at any time?
That depends on your wording. Aviva's April 2025 clause and Vitality's August 2024 clause both allow cancelling before the year is out, on the terms described above; for any other insurer, ask what notice is needed and what you would lose.
Can you cancel health insurance online?
How notice is given is up to each insurer. Ask yours which methods count, a letter, a call or an online request, and keep its reply, so that your notice reaches it in a form it acts on.
Can health insurance cancel you?
Whether an insurer can end a policy, or decline to renew it, depends on that policy's terms, so do not rule it out. If your insurer says cover is ending, ask it to put the reason and the last day of cover in writing, and start looking at alternatives while the policy is still in force.
Is there a penalty for cancelling health insurance?
On Vitality's August 2024 wording, leaving before the 12 month term is up may mean a £40 administration fee. Aviva's April 2025 clause names no fee, but premiums paid for cover up to the cancellation date are not refunded. For any other insurer, your own wording is where to look.
What is the cooling off period for health insurance?
The length varies by insurer and policy, and Aviva's April 2025 wording refers to one. Your policy documents or your insurer will say how long yours is, or the broker who phones back can explain it free, so do not assume a particular number of days.
Can I cancel a policy after it has renewed?
Whether renewing starts a new cooling off period, and what leaving soon after would cost, depend on the policy. Treat a renewed policy as one that may carry terms like those above, and ask your insurer in writing before agreeing a start date elsewhere.
If cancelling is the first half of a switch, get the replacement agreed and written down before the old policy is touched. The enquiry form here takes a few minutes with your renewal date and current schedule to hand, and the first thing to ask is whether your existing terms would be honoured by a new insurer.
