For most UK policyholders, private health insurance renewal premiums rise by around 6 to 12% a year, though your individual increase can be higher or lower. This is driven by two main things: medical inflation, which has been running at roughly 8 to 10% a year, and age-band increases as you get older. On top of that, your insurer’s own costs and claims experience feed in. Industry forecasts suggest annual rises in this range will continue through 2026 and 2027. So a modest single-digit rise is normal, but repeated large increases well above this, with no change to your cover, are worth challenging by comparing the market.

A bigger-than-expected jump usually comes from several things stacking up at once. Age-band step-changes are a common cause: premiums step up more sharply at certain ages, often around 35, 45, 55 and 65, so you can see a leap even if nothing else changed. Medical inflation adds a general rise across the whole market. If you’ve made a claim, you may also lose some or all of your no-claims discount, which combined with the annual rises can make a premium feel like it has jumped a lot in one go. Insurance Premium Tax at 12% amplifies every increase too, since it’s charged on top of the higher premium.

Yes. Almost all UK private health insurance policies rise at renewal each year, even if you’ve made no claims, because you move into an older age band and medical inflation pushes up the underlying cost of care across the whole market. This applies to essentially all mainstream insurers, so a yearly increase itself isn’t a sign anything is wrong. What’s worth questioning is the size: single-digit percentage rises are typical, whereas repeated increases of 20% or more, with no change to your cover, are a red flag that it’s time to review and compare the market rather than auto-renew.

Aviva, like other UK insurers, typically increases renewal premiums by a single-digit to low-double-digit percentage each year, reflecting medical inflation of around 8 to 10% plus any age-band step-change, though your exact figure depends on your age, claims and cover. Aviva doesn’t publish a fixed annual increase, and your renewal letter, usually sent four to six weeks before your anniversary, will show the new premium. Aviva also offers wellness-linked discounts that can reduce the rise if you engage with them. As with any insurer, the most reliable way to judge whether an Aviva renewal is fair is to compare it against equivalent cover from other insurers before accepting.

Several levers genuinely help. Raising your excess is the quickest, often cutting 15 to 25% off the premium. Trimming your cover, such as reducing outpatient limits or the hospital list, lowers it further while keeping core protection. Comparing the market at renewal is the single most effective step, because the same person is quoted very differently between insurers, and loyalty rarely pays. Switching on continued personal medical exclusions terms keeps cover for existing conditions. And engaging with wellness or no-claims schemes, where offered, can reduce future rises. What doesn’t work is simply accepting the renewal letter without checking whether a better deal exists elsewhere.

Switching can genuinely reduce your premium, because a new insurer may offer a fresh no-claims discount and a more competitive starting price, but it isn’t automatically the answer. The main thing to check is how pre-existing conditions will be treated: moving on continued personal medical exclusions terms preserves cover for conditions already recognised, whereas fresh underwriting could newly exclude them. So switching tends to suit healthier policyholders most. Even if you don’t move, getting comparison quotes gives you leverage to negotiate with your current insurer’s retention team. The sensible habit is to review and compare at every renewal, then switch only when it clearly leaves you better off overall.
