Quick Answer
You can switch private health insurance at any renewal (or mid-policy with notice), and the single most important thing is to switch on a CPME basis — Continued Personal Medical Exclusions. CPME means your new insurer mirrors your old policy’s terms instead of re-assessing your medical history, so conditions covered before stay covered and you don’t pick up new exclusions. Always line up and start the new policy before cancelling the old one, and never switch mid-treatment.
Done right, switching health insurance can cut a premium that’s jumped at renewal, or get you better cancer, mental health or outpatient cover for a similar price — without losing any cover you already have.
What this guide covers
Thinking of changing your private health insurance provider — for cheaper premiums, better coverage, or different benefits? Switching health insurance in the UK can be straightforward if you understand one crucial concept (CPME) and follow the right order. This guide walks you through how to switch health insurance without losing cover or making costly mistakes. Going Private UK is editorially independent; we may earn commission when readers compare cover through our links, which funds our research but doesn’t affect our advice.
Why people switch health insurance
- Premiums have jumped at renewal — the number-one reason. Increases of 10–25%+ a year are common as you age and with medical inflation.
- Your plan doesn’t cover something you now need — a treatment, hospital or higher limit.
- You want better cancer or mental health cover.
- You’re now eligible for a better deal — through work, a group scheme, or an age-based policy.
Before switching just for price, it’s often worth trying to negotiate your renewal first — but if that fails, switching is your lever.
Can You Switch From One Health Insurance to Another?
Yes — you can switch from one health insurance provider to another whenever you like, and you don’t have to stay with the same insurer for life. There’s no penalty for moving, and you’re free to change provider at renewal or, in most cases, mid-policy with notice. The thing that makes switching safe rather than risky is how you move across — specifically, switching on CPME so your medical history transfers with you.
The short version
- Can you switch from one insurer to another? Yes — freely, and as often as you like.
- Will you lose cover? Not if you switch on CPME (see below). You only risk it with fresh underwriting.
- Best time? Renewal is cleanest, but mid-policy switching is usually allowed with notice.
- Does it cost anything? No switching fee — but your no-claims discount usually doesn’t transfer.
The same principles apply whether you’re switching health insurance as an individual or switching medical insurance for a family or couple — the mechanism (CPME) is what protects you in every case.
CPME: the key to switching without losing cover
This is the most important part of the whole guide, and the thing most people don’t know about when they switch medical insurance.
💡 What is CPME?
Continued Personal Medical Exclusions (CPME) — sometimes called “switch underwriting” — is a method where your new insurer accepts you on the same terms as your old policy, rather than re-underwriting you from scratch. Conditions that were covered stay covered; conditions that were excluded stay excluded. Crucially, you don’t pick up new exclusions for conditions that developed while you were insured. It’s the mechanism that makes switching safe.
Here’s why it matters so much. If you instead switch on new full medical underwriting (FMU) or a new moratorium, any condition you’ve developed since your original policy started can be treated as “pre-existing” by the new insurer — and newly excluded. That’s how people accidentally lose cover by chasing a cheaper price.
- Switch on CPME → your medical history transfers, cover stays intact, no new waiting period.
- Switch on new FMU/moratorium → conditions from the last few years may be re-excluded.
- Ask every new provider specifically about CPME, and get a written statement of transferred exclusions before you commit.

What to check before switching health insurance
- Pre-existing conditions: will they still be covered? (This is where CPME is essential — see pre-existing conditions explained.)
- Underwriting basis: confirm you’re switching on CPME, not new FMU/moratorium.
- Waiting periods: CPME means no new waiting period; new underwriting may reset them.
- Excess & policy tier: are you genuinely getting better cover, or just cheaper? Check the excess and compare comprehensive vs basic cover.
- Hospital list: make sure the hospitals you want are included.
- No-claims discount: this usually does not transfer between insurers — see how no-claims discounts work.
- Cancellation terms on your current policy.
How to Switch Health Insurance: Step-by-Step
- Review your current policy documents — note your underwriting basis, exclusions, excess and renewal date.
- Compare new quotes and benefits — on a like-for-like cover basis, not just price.
- Ask the new insurer about CPME — confirm they’ll accept you on continued personal medical exclusions, and get the transferred exclusions in writing.
- Get written confirmation of your new cover and its start date.
- Only cancel your old policy once the new one has started — never leave a gap in cover.
When you’re ready to cancel the old policy, see our provider guides: cancel Bupa, AXA, Aviva, Vitality and WPA.
Can you switch health insurance anytime?
Most people switch at renewal, which is the natural break point. You can usually also cancel mid-policy with notice (often 30 days — check your contract). New policies generally come with a 14-day cooling-off period, so you can change your mind shortly after starting. A cooling-off period gives useful breathing room, but switching at renewal is usually cleanest.
When you should NOT switch
⚠️ Hold off switching if…
You’re currently undergoing private treatment — switching mid-treatment risks the new insurer treating it as pre-existing and not covering the rest. Finish the episode first.
You’ve recently developed a condition and can’t get CPME — if a new insurer will only offer fresh underwriting, you could lose cover for that condition. Stay put or insist on CPME.
You’re switching jobs and cover is involved — the rules differ; see health insurance when changing jobs.
Who typically switches?
- Self-employed professionals optimising cover and cost.
- Families reviewing joint cover or adding children.
- Over-50s and over-60s seeking better cancer or outpatient cover — see health insurance over 50.
- Businesses re-broking group schemes — see switching business/SME cover and medical history disregarded (MHD).
The bottom line
Switching health insurance isn’t difficult — but it must be done on CPME to protect your cover. Compare on a like-for-like basis, confirm continued personal medical exclusions in writing, line up the new policy before cancelling the old one, and never switch mid-treatment. Done properly, you can cut a rising premium or get better cover without losing anything you already have.

Frequently Asked Questions
Can I switch from one health insurance to another?
Yes — you can switch from one health insurance provider to another freely, at renewal or usually mid-policy with notice, and as often as you like. There’s no penalty for moving. The important thing is to switch on CPME (Continued Personal Medical Exclusions) so your medical history transfers and you don’t lose cover for conditions that developed while you were insured.
Can I switch health insurance with a pre-existing condition?
Yes — this is exactly what CPME (Continued Personal Medical Exclusions) is for. If your condition was covered by your old policy, it stays covered; if it was excluded, it stays excluded. The key is switching on CPME (not fresh underwriting) without a break in cover, so you don’t gain new exclusions for conditions that developed while you were insured.
Can I switch health insurance at any time?
Most people switch at renewal, but you can usually cancel mid-policy with notice (often 30 days — check your contract). New policies generally include a 14-day cooling-off period. Switching at renewal is usually the cleanest option.
Will I lose cover if I switch insurers?
Not if you switch on CPME, which mirrors your old policy’s terms. You risk losing cover only if you switch on new full medical underwriting or a new moratorium, which can re-exclude conditions developed since your original policy started. Always confirm CPME in writing first.
How do I switch medical insurance without a gap in cover?
Get written confirmation of your new policy’s start date, make sure it begins before your old one ends, and only cancel the old policy once the new one is live. Never leave a gap, as it can affect continuity of cover.
Does my no-claims discount transfer when I switch?
Usually not — no-claims discounts generally don’t transfer between insurers, so factor that into the price comparison. Your underwriting history can transfer via CPME, but the discount typically resets.
When should I not switch health insurance?
Avoid switching while you’re undergoing private treatment, if you can’t secure CPME after developing a new condition, or without first checking job-change implications. In these cases switching could leave you worse off — staying put or insisting on CPME is safer.
