Can I cancel part-way through the year?

Usually yes, subject to the notice period in your policy. Check your policy documents, as some premiums are payable for the full year.

Will I lose cover for a condition if I switch insurer?

Possibly. New policies often exclude pre-existing conditions, so ask the new insurer in writing what will be covered before you cancel.

Re: Cancellation of health insurance policy

Dear Sir or Madam,

I am writing to cancel my private health insurance policy with policy number with effect from the earliest date allowed by the notice period in my policy. This cancellation covers the main policy and any add-ons, such as dental or optical cover, held under the same policy number.

Please confirm the following to me in writing: - that you have received and actioned this cancellation; - the date on which the cover ends; - whether any claims are still outstanding.

I am also cancelling the Direct Debit for this policy with my bank with effect from the end date. Please do not present any further collections after that date, and please refund any premium already paid for the period after the end date.

Yours faithfully,

What to look out for

If you are taking out a new policy, start it before this one ends — a gap in cover can mean existing conditions are excluded from the new policy.
If you are part-way through treatment, ask in writing what will and will not be covered after the end date.
Have an outstanding claim? Submit it before the end date and keep a copy.
Cancel any add-ons such as dental or travel cover separately if they are held under a different policy number.
