Common Triggers

Reasons People Switch At Renewal

There's rarely just one reason. Here are the most common triggers we see.

1

A Bigger Increase Than Expected

The number one trigger, a renewal price that's risen well beyond age and general medical inflation.

2

Better Benefits Elsewhere

Another insurer may offer stronger mental health support, cancer cover, diagnostics, or a wider hospital list.

3

Poor Service Or Claims

Long call waits, a complicated claims process, or unhelpful support when you needed it most.

4

Your Circumstances Changed

Marriage, a new child, employer-funded cover ending, or your priorities simply shifting.

One caveat worth flagging

If you have a pending or ongoing claim, it's generally not advisable to switch until it's resolved, see "When You Probably Shouldn't Switch" further down this guide.

Your Options

Stay, Negotiate, Or Switch?

A renewal increase doesn't mean you only have one option. Here's how to think about it.

Weighing up whether to stay, negotiate or switch health insurance at renewal

Stay

  • You're mid-claim or recently treated
  • You value cover already accepted for a condition
  • Your increase is small and in line with the market

Negotiate

  • You've been with your insurer 5+ years
  • Retention teams sometimes offer a discount to keep you
  • Costs nothing to ask before you switch

Switch

  • Your increase feels disproportionate
  • You're not mid-claim, with no active condition tied to your current plan
  • Another insurer offers better value for similar cover

Why It Happens

Why Does Health Insurance Go Up At Renewal?

Nobody enjoys a renewal increase, but understanding why it happens helps you judge whether yours is reasonable. See our cost guide for how prices typically compare by age.

Age

Premiums naturally rise each year as the statistical likelihood of claiming increases with age.

Medical Inflation

The cost of treatments, drugs and technology often rises 8-10% a year, well above general inflation.

Your Claims History

Making a claim can increase your renewal price, sometimes significantly, depending on your insurer's pricing model.

The Biggest Concern

Will I Lose Cover For A Condition I've Already Been Accepted For?

This is the single biggest reason people stay put even when they're unhappy with their renewal price. The good news: in most cases, you don't have to choose between switching and keeping that cover.

Continued Personal Medical Exclusions (CPME), sometimes called switch underwriting, is the mechanism that allows this. If a new insurer agrees to match your existing terms, conditions already accepted and covered under your current policy can continue to be covered under the new one, without restarting underwriting from scratch.

1

Your new insurer reviews your current policy's terms and accepted conditions.

2

If they agree to match them, those conditions transfer across under CPME.

3

Anything not previously covered is medically underwritten as normal.

How Does Your Insurer Handle Renewals?

Renewal behaviour varies a lot between insurers. Here's what to expect from each of the UK's leading providers.

InsurerRenewal BehaviourWorth Knowing
BupaAuto-renews unless cancelled in writing.Retention teams sometimes offer a modest discount for long-standing (5+ year) customers, worth asking before you switch.
AvivaStandard annual renewal.The "My Healthy Discount" applied in year one may not repeat at renewal, check whether it's still reflected in your price.
AXA HealthStandard annual renewal.Offers both a 3-year and the standard 5-year moratorium look-back product.
VitalityUses ABC pricing (Age, Base inflation, Claims) rather than a traditional no-claims discount.Disengaging from the rewards programme can push your renewal price up, staying active can help offset the increase.
The ExeterStandard annual renewal, mutual insurer.£300 small-claims no-claims-discount protection can soften the impact of a minor claim on your renewal.
WPAStandard annual renewal.The optional Shared Responsibility (coinsurance) structure can be adjusted at renewal to help manage cost.
SagaStandard annual renewal.The no-claims discount applies policy-wide, not per person, so one family member's claim can affect everyone's renewal.
Freedom Health InsuranceMoved from community-rated to performance-based renewals following a 2024 ownership change.Several recent reviews describe steep renewal increases following a claim, worth comparing carefully each year.
HMCAStandard annual renewal via your qualifying membership group.Cover is generally fixed-benefit rather than full treatment cost, worth checking your specific benefit schedule hasn't changed at renewal.

Be Careful

When You Probably Shouldn't Switch

Switching isn't always the right call. Here's when it's worth staying put, at least for now.

You're Mid-Claim

It's very difficult, and generally not advisable, to switch insurers while you have an active or ongoing claim.

Recently Treated

If you've just had treatment for a condition, switching could mean starting underwriting from scratch for anything related to it.

Condition Won't Transfer

If a prospective new insurer won't offer CPME for a condition you're currently covered for, staying put may protect more valuable cover.

Increase Is Reasonable

A small increase in line with age and medical inflation may not be worth the hassle of switching for a marginal saving.

Try This First

Negotiate Before You Switch

Before you compare the wider market, it's worth a quick call to your existing insurer, it costs nothing and sometimes pays off.

Ask About Loyalty

Long-standing customers (5+ years) can sometimes access a retention discount not offered upfront.

Query The Increase

Ask exactly why your premium rose, age, claims, or general repricing, and whether it can be reviewed.

Compare Regardless

Even if you negotiate a better price, it's worth knowing what the wider market offers before you commit.

Compare While You Decide
Staying Put?

Ways To Reduce Your Premium Without Switching

If you've decided to stay with your current insurer, a few simple changes can still bring your renewal price down.

Up to 25% cheaper

Raise Your Excess

Raising your excess from £100 to £500 typically cuts your premium by 15-25%, provided you can afford that amount at claim time.

Up to 30% cheaper

Add The 6-Week NHS Option

Agree to use the NHS if it can treat you within 6 weeks, cutting many plans by 20-30%.

Review Your Hospital List

A wider hospital list, especially one including Central London, usually costs more, ask about a more focused list.

Reassess Optional Extras

Dental, optical, therapies or travel add-ons are useful, but only if you'll actually use them.

How To Actually Switch

If you've decided switching is right for you, here's how the process typically works.

1

Compare Quotes Elsewhere

Get quotes from leading UK insurers based on your current cover level.

2

Check CPME Eligibility

Ask whether the new insurer will match cover for any existing conditions.

3

Apply For New Policy

Set cover to start the day your old policy ends, avoiding any gap.

4

Send Your Policy Certificate

Your new provider needs your current underwriting terms to continue them over.

5

Cancel Your Old Policy

Most insurers require written confirmation before your renewal date.

FAQs

Health Insurance Renewal FAQs

Why has my health insurance renewal price gone up?

Usually a combination of your age, medical inflation (often 8-10% a year), and your claims history. Some increases are reasonable and market-wide, others are worth challenging or comparing elsewhere.

Can I switch health insurance without losing cover for an existing condition?

Often, yes, through Continued Personal Medical Exclusions (CPME), also called switch underwriting. If your new insurer agrees to match your current terms, conditions already accepted can transfer across.

How much could I save by switching at renewal?

Independent market research suggests £250 to £500 a year on average, though this is an indicative estimate rather than a guarantee, your own saving depends on your current premium, age, cover level and claims history.

When should I start comparing before my renewal?

As soon as you receive your renewal notice, typically 3-6 weeks before your policy anniversary, giving you time to compare and switch without a gap in cover.

Should I negotiate with my current insurer first?

It's worth a try, particularly if you've been with them 5 or more years. Retention teams sometimes offer a discount to keep long-standing customers, though it's still worth comparing the wider market regardless.

Is it ever a bad idea to switch?

Yes, if you're mid-claim, have recently been treated for a condition, or a prospective new insurer won't match your existing accepted conditions under CPME. In these cases, staying put may protect more valuable cover.
