Health insurance
What affects the price of health insurance?
The short answer
Insurers price on age, postcode, cover level (especially outpatient limits), the excess you accept, the hospital list you choose, your underwriting basis and, on some policies, your claims history through a no-claims scale. Medical inflation pushes renewal prices up even without claims. Each lever is documented in the policy documents.

Thinking about what affects the price of health insurance
What works well
- Benefit-design levers let you trade cover for price deliberately.
- A higher excess can cut the premium meaningfully.
- Guided options reduce cost by using the insurer’s agreed networks.
What to watch
- Each price cut removes a specific piece of cover — know which.
- Postcode pricing reflects local private treatment costs.
- Medical inflation raises renewals even for claim-free years.
The levers you actually control
Age and postcode are fixed inputs — they reflect the cost of private treatment where you live and the statistical risk at your age. The levers you control are the benefit design: a lower outpatient limit or none at all, a higher excess, a narrower hospital list and guided consultant options all reduce the premium, because each one transfers cost or choice back to you. Claims history matters where the policy runs a no-claims scale. Medical inflation — the rate at which treatment costs rise — lifts the whole book at renewal regardless of your own claims: WTW measured UK medical cost trend at 10.6 per cent in 2025 and projected around 10 per cent for 2026 (source 5).
Ask for your renewal broken down by age, claims and book-level increase; an insurer operating under the Consumer Duty should be able to explain the composition. Whatever the specifics of what affects the price of health insurance, the discipline that protects you is always the same: get the insurer’s position in writing before treatment, keep the documents, and compare like with like. The CMA’s private healthcare market investigation imposed order-backed requirements on the private hospital market precisely because opacity on price and information harms patients. [2] The Private Healthcare Information Network exists to publish comparable performance and pricing information for private hospitals. [3]
What moves the price
Premiums are priced annually and re-rated at renewal. The inputs an insurer can use include your age, your postcode, the level of outpatient cover you choose, the excess you accept, the hospital list you select and, on some policies, a no-claims discount scale. Medical costs have historically risen faster than general inflation, which is why premiums can climb even when you do not claim: WTW measured UK medical cost trend at 10.6 per cent in 2025 and projected around 10 per cent for 2026. [5] Premiums carry Insurance Premium Tax at the standard rate of 12 per cent. [4]

The workplace share of the market matters when you think about price: if your employer already provides cover, the question shifts from “what would a policy cost me” to “what gaps does the scheme leave”. Average premium figures circulate widely online, but an average built from different ages, postcodes and benefit levels cannot predict your quote — treat any average without a named source and date as unusable.
How to compare two quotes
- Fix the cover first: outpatient limit, excess, hospital list and underwriting type.
- Ask for each quote in writing, with its date.
- Put the quotes side by side and mark every difference in cover before you look at price.
- Ask what happens to the price at renewal and after a claim.

Common questions
- Why do two people the same age sometimes get very different quotes?
- Age is only one input. Postcode reflects the cost of private treatment where you live, and the benefit design you choose — the outpatient limit, the excess, the hospital list and whether you accept guided consultant options — can move the price substantially in either direction. Claims history also matters on policies that run a no-claims scale. Two people of the same age with different combinations of these choices can end up with noticeably different premiums, which is why comparing quotes only makes sense once the specification is fixed and identical.
- Can I reduce my premium without giving up the cover I actually use?
- Often, yes, if you look at which levers match how you actually use a policy. A higher excess lowers the premium and only applies if you claim, so it can suit someone who rarely claims. A narrower hospital list or guided consultant options can cut cost without removing cover for treatment itself, provided the list still includes facilities you would realistically use. The discipline is to test each lever against a written quote and check exactly what cover is reduced, rather than assuming cheaper automatically means worse.
- Why does my premium rise even though I did not claim this year?
- Renewal pricing is not only about your own claims. Insurers also adjust for your age moving up a band and for medical inflation, which is the rate at which the cost of treatment, drugs and technology rises across the whole book of policyholders. This book-level movement applies whether or not you personally claimed, which is why a claim-free year does not guarantee a flat renewal. Asking the insurer to break the increase into its components can clarify how much is age, how much is claims and how much is the general book adjustment.
