How Much Does Health Insurance Go Up Each Year in the UK? (Renewal Inflation Guide 2026)

Got a renewal letter that jumped more than you expected? You’re not alone. Many people in the UK see their private health insurance premium go up each year – sometimes by more than inflation – and aren’t sure if it’s “normal” or if they’re being ripped off.

This 2026 guide explains why health insurance goes up each year, what’s typical, what’s not, and the levers you can pull to bring the price back down without throwing away good cover.

How UK Health Insurance Renewals Work

With most UK health insurers, your policy runs for 12 months at an agreed price. Towards the end of that year, the insurer recalculates your premium for the next year based on:

• Your new age (you’re a year older).
• Medical inflation – how much hospitals, consultants and drugs now cost them.
• Your claims history (on some policies).
• Changes to your benefits (e.g. outpatient, mental health, hospital lists).
• The insurer’s overall book of business (how profitable your group of similar customers is).

That’s why two people the same age can see very different increases – even with the same insurer.

If your renewal is higher than you’d like, you don’t have to either blindly accept it or cancel everything. There’s a whole middle ground: tweaking cover, adjusting excess, or switching to a better-fit insurer. Our guide to negotiating health insurance renewals covers this in more detail.

What’s a “Normal” Health Insurance Increase Each Year?

There’s no single “standard” increase – and insurers rarely publish simple averages – but in broad terms, many customers see annual rises:

These are illustrative ranges only. Your own renewal may be higher or lower than these examples.

7 Main Reasons Your Premium Goes Up

Most renewal letters boil down to some mix of these seven factors:

1. Your age: health insurance is age-rated. As you move into higher age bands (40s, 50s, 60s, 70s), your risk of needing treatment goes up – and premiums follow.
2. Medical inflation: the cost of consultants, theatres, drugs and diagnostics often rises faster than general inflation. We’ve got a separate guide on why health insurance premiums are rising.
3. Your claims history: some insurers and products load premiums more heavily if you or your family have made significant claims.
4. Benefit level: policies with unlimited outpatient, full mental health, rich cancer cover and big hospital lists are naturally more exposed to cost increases.
5. Hospital list changes: upgrading to a more expensive hospital list (for example to include central London hospitals) can push premiums up both at the time and at renewal.
6. Underwriting type: some switch deals (like CPME – Continued Personal Medical Exclusions) can become expensive over time if the insurer’s risk pool is small or high-claim.
7. Insurer repricing: occasionally insurers reprice entire books of business – particularly older products – leading to steeper-than-normal jumps in a single year.

Age Bands: The Hidden Jumps at 50, 60, 65 and 70

One of the most confusing parts of health insurance pricing is age bands. You don’t just pay a little more because you’re one year older – premiums can jump more noticeably when you cross certain age thresholds.

While each insurer has its own structure, increases tend to be more pronounced when moving through age ranges like:

• 40 → 50s (more diagnostics, joint issues, early chronic conditions).
• 50 → early 60s (higher probability of surgery and cancer treatment).
• Mid-60s → 70s+ (more complex, costly claims).

That’s one reason many people explore cover in their 50s or early 60s – before hitting the steeper parts of the curve. See our guides to health insurance for over 50s, over 60s and seniors over 70.

How to Tame a Painful Renewal (Without Losing Good Cover)

Before you cancel your policy entirely, it’s worth seeing how much you can shave off by adjusting the dials:

• Review your hospital list: moving from a full national list with all top London hospitals to a slightly more restricted list can save a surprising amount. See Bupa hospital list, Aviva, AXA and Vitality.
• Set a sensible excess: increasing your health insurance excess from £100 to £250 or £500 can reduce premiums, especially on rich policies.
• Adjust outpatient cover: moving from unlimited outpatient to a £1,000 or £500 limit – or even diagnosis-only in some cases – can reduce cost whilst still giving you fast answers. See outpatient limits and best low-outpatient plans.
• Check optional extras: dental, optical and certain lifestyle add-ons can be trimmed if you’re not using them.
• Ask for a review: some insurers will offer alternative configurations or plan levels if you say you are considering leaving.

Should You Switch Insurer or Stay Put?

When renewal increases feel unfair, switching insurer can be tempting – and sometimes it’s the right call. But there are trade-offs:

Reasons to stay with your current insurer

• You’ve built up cover for certain conditions under moratorium underwriting.
• You’re happy with how claims are handled and which hospitals you can use.
• You’ve recently had treatment and don’t want to rock the boat.

Reasons to consider switching

• You’ve had repeated double-digit increases and the benefits no longer feel worth it.
• Your insurer is pushing you onto a newer, more expensive product.
• You can get similar or better cover elsewhere for significantly less.

If you do switch, look carefully at:

• Underwriting basis: new moratorium vs CPMe vs fully underwritten.
• Hospital lists: are your preferred hospitals still included?
• Outpatient and cancer cover: are there any new caps or limits?

Our main best health insurance UK comparison and switching health insurance guide are good starting points if you’re thinking of moving.

What About Business & Employee Health Insurance?

If your cover is paid through a limited company or employer, renewal works slightly differently:

• Pricing is often based on the claims experience of the whole group, not just you.
• Smaller SME schemes (2–50 employees) can see sharp rises after heavy claims – but there are levers, such as higher excesses or guided options.
• Larger schemes can sometimes choose different underwriting approaches or add claims cost controls.

FAQs – Health Insurance Renewal Increases in the UK

Why did my health insurance go up when I didn’t claim?

Even with no claims, your premium is still affected by age and medical inflation, plus the claims made by other people on the same plan or in the same risk pool. That said, a clean claims history can still help keep increases more manageable than they might otherwise be.

Can I refuse the renewal increase?

You can always refuse and cancel – but that leaves you uninsured. A better starting point is to ask your insurer or a broker to model alternative configurations (excess, outpatient limit, hospital list) and compare with new-customer quotes from other providers before deciding.

Is it cheaper to cancel and restart later?

Often not. You’ll be older when you restart, may have new health conditions, and might face more exclusions. In many cases, shaping your existing policy is a better long-term strategy than stopping and starting.

Does switching insurer reset my exclusions?

It depends on the underwriting type you move to. On some switch terms (like CPMe), you carry your existing exclusions across; on others, new exclusions may be applied. Always get this explained in plain English before you switch.

Can I spread the cost to make increases easier to manage?

Many insurers offer monthly payments at no extra cost. If you’re self-employed or a director, paying through your business may also change the overall picture – see private healthcare through your business.

If you’ve had a renewal that doesn’t feel right, the most helpful next step is usually to see what else is out there at your age and cover level, then decide whether to stay, reshape or switch.
