Switching health insurance: the details to compare
A new policy can change more than the premium. Before comparing options, it helps to understand the cover you already have and how the proposed policy would differ.
Where to start
Compare benefits, exclusions, existing conditions, qualifying periods, costs, service and confirmation of new cover before ending old cover.
Key points
Compare benefits
The new policy should be compared against the current one for benefits, limits, excesses, exclusions and claims process, not price alone.
Check waiting periods
A new policy can include stand-down, qualifying or waiting periods that affect when benefits can be used.
Check pre-existing conditions
Health history and underwriting terms may change when switching, so existing-condition treatment needs its own check.
Confirm new cover first
Ending old cover before the new policy is confirmed can create avoidable gaps or lost terms.
Compare cover, not just cost
Look at what changes in benefits, limits, exclusions, qualifying periods, excesses and pre-approval rules. A cheaper quote can still be less useful if important cover is lost.
Check existing-condition treatment
Health history can be treated differently under a new policy. Compare existing terms with proposed terms before assuming the switch is like-for-like.
Avoid a gap
Use insurer confirmation before cancelling existing cover, especially where pre-existing conditions, waiting periods or underwriting decisions could matter.
Ask what is not changing
A clear switching conversation should explain what stays the same, what changes, what is uncertain and what would need written confirmation before a decision is made.
What to check next
- Whether to switch depends on the old and new policy wording and personal circumstances.
- Policy and underwriting details can change the answer.
- Use authorised advice where the decision depends on your circumstances.
