Yes, you can usually cancel private health insurance at any time, but what happens next depends on timing. Within the cooling-off period, normally the first 14 days from the start or renewal of your policy, you can cancel and get a full refund provided you haven’t made a claim. After that, you can still cancel mid-term, but refunds become policy-specific: annual payers may get a pro-rata refund minus an admin fee, while monthly payers often get little or nothing back because each month’s premium has already covered the time insured. There’s usually a notice period too, often around 30 days, so check your documents. The bigger consideration isn’t whether you can cancel, but whether it is wise, because cancelling outright can cost you continuity of cover for any conditions treated while insured.

It depends on when you cancel and whether you’ve claimed. If you cancel within the 14-day cooling-off period and haven’t made a claim, you’re legally entitled to a full refund of any premium paid. If you cancel mid-term after paying annually and haven’t claimed, you may get a pro-rata refund for the unused months, usually minus an admin fee or a charge for the time you were on risk. Monthly payers typically get little or no refund, because each month has already paid for the cover you had. If you’ve made a claim, a refund is usually unavailable, and the insurer may require you to continue the policy or deduct the claim cost. Always ask your insurer to confirm any refund figure and deductions in writing before finalising.

If you still want private cover, switching is almost always safer than cancelling outright, because cancelling can lose you continuity of cover. Any condition that developed while you were insured can be treated as pre-existing, and therefore excluded, by a new insurer if there’s a gap. Switching on CPME (Continued Personal Medical Exclusions) terms carries your existing underwriting across, so those conditions stay covered. Cancelling outright only really makes sense if you genuinely no longer want private cover, for example if you’re joining an employer scheme. If your reason for cancelling is cost, it’s usually worth comparing the market or negotiating your renewal first, since you can often reduce your premium, by raising the excess or trimming cover, while keeping protection rather than losing it entirely.

The biggest risk is losing continuous cover, which matters far more than any refund. While you’re insured, conditions you’re treated for are covered, but if you cancel and later take out a new policy, most insurers will treat anything that arose during the gap, or during your old policy, as a pre-existing condition and exclude it. The second major risk is cancelling mid-treatment: if you’re being investigated, have a referral, or are receiving ongoing treatment, cancelling can leave you paying for that care privately once cover ends. This is why switching on continuity terms, rather than cancelling, is usually the safer route if you still want cover, and why it’s crucial not to cancel while any claim or treatment is in progress.

Start by reviewing your policy documents to find the cancellation section, your notice period and contact details. Decide whether you’re cancelling outright or switching, as switching needs the new policy lined up first. Then contact your insurer or broker, by phone to start the process and in writing (email is fine) to confirm, stating clearly that you wish to cancel and the date you want cover to end. Ask them to confirm in writing the exact end date, any refund due and any fees. If you’re switching, set the new policy to start the day after the old one ends, or overlap by a day, and confirm it’s active before letting the old cover lapse. Keep the written confirmation as your proof. The cleanest time to leave is at renewal, avoiding mid-term fees.
