What to know about what affects the price of health insurance
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]
- All covered people6.5 million
- Through workplace schemes4.8 million
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.
