A private health insurance renewal can rise for several reasons, including medical costs, demand for care, claims, age-based pricing and Insurance Premium Tax (IPT). The mix varies by insurer and policy. Check the explanation for your own renewal, then compare ways to reduce the premium without overlooking what you would give up.
Key takeaways
- Treatment costs, claims experience, age-based pricing and IPT can all affect the amount you pay.
- Consider an affordable excess, a narrower hospital list, an NHS-wait option or fewer extras.
- Compare like-for-like at renewal and check the cover changes before agreeing to a lower premium.
- Do not cancel existing cover until replacement terms, start date and underwriting are confirmed.
Why health insurance premiums can rise
There is no single reason that explains every renewal. Insurers price policies differently, and the factors affecting one customer may not explain another’s increase. Ask your insurer to explain the change to your premium rather than treating a general market figure as a forecast for your policy.
Medical cost inflation
The cost of private treatment can rise as hospital facilities, specialist fees, medicines, equipment and newer treatments become more expensive. When eligible care costs more, insurers may pay more in claims across their policyholders. Aviva describes medical inflation and the cost of treatment and innovation as factors in health insurance premiums in its cost guide.
Demand and claims
More use of private healthcare can increase the number of claims insurers need to pay. The number and cost of your own claims may also affect your renewal, depending on the policy and any no-claims discount rules. Bupa says claims history, including claim count and cost, can affect renewal prices; Aviva also lists claims and wider pressure on healthcare services among its pricing factors. See their Bupa cost guide and Aviva cost guide.
This is one reason a renewal can rise even if you have not claimed: the insurer may also be responding to its wider claims costs, treatment prices or other pricing factors.
Age-based pricing and age bands
Age can affect health insurance pricing because the likelihood of needing treatment may change over time. Some policies may adjust prices as age changes; others may use age bands. The method and band boundaries are insurer-specific, so ask whether your renewal reflects your age, a move into another band, claims or general repricing. Aviva and Bupa both list age among the factors that can affect price.
Insurance Premium Tax (IPT)
IPT is a tax on premiums for taxable insurance contracts. HMRC lists the standard rate as 12% and says medical insurance is not included in the exemption for long-term insurance. Taxable private medical insurance premiums therefore fall under the standard rate. Where IPT applies, it contributes to the total premium; a change to the tax rate can affect what you pay even if the insurer’s underlying price is unchanged. See HMRC’s IPT guidance and Notice IPT1 for the rates and exemptions.
Ways to reduce your premium
Every saving changes either the amount you pay when claiming or the care you can access. Ask for revised terms in writing and weigh the trade-off against what matters to you.
Choose an affordable higher excess
Increasing your excess may lower the premium, but you would pay more yourself when making an eligible claim. Choose an amount you could afford and check whether the excess applies per person, per condition, per claim or per policy year under the specific policy. Read our guide to choosing a health insurance excess for more detail. Bupa’s premium guide also explains how excess choices affect premiums and claim costs.
Restrict your hospital list
A smaller hospital network can reduce the premium, but may limit where you can receive eligible treatment. Check that hospitals and specialists you would realistically use are included, and ask how referrals work if your preferred provider is outside the list. Aviva’s cover options describe less extensive hospital options as one way to reduce premiums.
Consider an NHS-wait option
Some health insurance policies offer a six-week NHS-wait option. Under Aviva Healthier Solutions, if you select this option, inpatient and day-patient treatment is not covered when the treatment is available on the NHS within six weeks of the date your specialist recommends it. Aviva’s terms say this includes accident and emergency admissions. This is specific to Healthier Solutions, not a rule for every policy. Check the Healthier Solutions terms and conditions and Aviva’s explanation of cover options.
Other insurers’ published terms use different triggers and benefit scopes:
- AXA Health: Its member FAQ says the six-week option can apply to inpatient and day-patient treatment and surgical procedures if the NHS cannot provide the treatment within six weeks of when it should take place. It does not apply to consultations or treatment with a therapist or practitioner. AXA says this is one type of cover a member might have, so check your own membership documents.
- Bupa Select SME: The 2026 policy guide measures the wait from when a consultant says treatment is needed. It includes eligible inpatient and day-patient treatment, including diagnostic procedures. The scheme does not apply to outpatient treatment, requires confirmation each time and removes the NHS inpatient cash benefit (CB1). However, Bupa’s 2026 change notice says the scheme is removed at renewals on or after 1 September 2026, except that it remains until the end of an existing two-year fixed-rate term. Check your current membership certificate before treating it as part of your cover.
Review optional extras
If you pay for optional cover you do not need, ask what happens if you remove or reduce it. Depending on the plan, this could include outpatient limits, therapies, dental or optical benefits. Check whether the benefit can be added back later and whether that would require new underwriting. Aviva’s cover options guide gives examples of options that can be adjusted.
Compare policies at renewal
Put the renewal offer beside your current schedule and any competing quotes. Match the people insured, underwriting basis, excess, outpatient cover, hospital access and optional benefits as closely as possible. A lower quote may reflect narrower cover or different exclusions, not simply a better price.
Ask your current insurer whether it can offer a different policy configuration or explain the renewal change. Get the new price, benefits, excess, network and exclusions in writing before you agree. Our renewal tips guide has a step-by-step review checklist.
If you are thinking about switching
The new premium is only part of the comparison. A new insurer may assess your medical history differently, apply exclusions or offer different benefits. Ask how any existing exclusions or underwriting terms will be handled and get the answer in writing. Do not cancel your current policy until the replacement cover, start date and terms are confirmed.
Renewal checklist
- Ask the insurer which factors changed your premium and separate price changes from changes to cover.
- Compare the renewal with alternatives on the same excess, hospital access, limits, benefits and underwriting basis.
- Check the price and claim-time trade-offs for any excess, hospital-list or NHS-wait change.
- Confirm new exclusions and the start date before switching; do not leave a gap in cover.
Frequently asked questions
Why did my premium rise if I did not claim?
Your own claims may be only one factor. Medical costs, wider claims experience, age-based pricing, tax or a change to your cover could also matter. Ask the insurer to explain your renewal specifically.
Will a higher excess always reduce my premium?
It may reduce the premium, but the amount depends on the policy. Compare the revised quote and make sure you could afford the excess if you claim.
Is the NHS-wait option available on every policy?
No. Availability, waiting-time rules and which treatments are affected depend on the insurer and plan. Check the policy wording before choosing it.
