Why does health insurance cost more as you get older?

Health insurance costs more as you get older because the risk of illness and injury rises with age, and the conditions that become more common, such as cancer, are expensive to treat. Insurers either raise your premium a little at each renewal as you age or price by age band, so you may see a bigger jump when you move into a new band.

In our March 2026 research, comprehensive cover for one adult averaged £42.69 a month at 20 and £207.27 at 70.

Claims, medical inflation and insurance premium tax push prices up too. You can keep the cost down by choosing only the cover you need, raising your excess, looking after your health and limiting your hospital and consultant choice.

How much are health insurance premiums?

What you pay for health insurance depends on several factors. However, to give you an idea of the cost, we conducted extensive research in March 2026 that revealed that the average health insurance premium for one adult in the UK is £82.53 per month (or £990.36 per year), averaged across all ages.

What affects the cost of health insurance premiums?

As with other types of insurance, health insurance companies will consider your risk profile, in other words, how likely you are to make a claim. The greater the chance, the more you can expect your insurance to cost. Considerations include:

  • Your age - is a hugely important factor in calculating health insurance premiums, and you’ll usually find policies increase as you age.
  • Your lifestyle - smoking can increase health insurance premiums as there are greater associated health risks.
  • Your medical history - if you’ve suffered from ill health or have some pre-existing medical conditions, it could mean you pay more for health insurance or have more exclusions than someone who hasn’t.
  • The policy you choose - the more features your policy includes, the more you can expect to pay.
  • Where you live - some regions are more expensive than others when it comes to the cost of medical treatment. Also, some areas affect health negatively, for example, densely populated places with heavy infrastructure and higher pollution levels. So, if you live in a large city, you can expect to pay more than someone the same age living in a rural or less stressful environment.

Why do health insurance premiums increase with age?

So, why does age affect health insurance premiums significantly? Fundamentally, the older we get, the higher the risk of injury or developing an illness. Also, the illnesses that could develop tend to be expensive to treat, for instance, cancer. In fact, according to Cancer Research UK, almost two-fifths (37%) of all new cancer cases in the UK are diagnosed in people aged 75 and over. Nearly one in two of us is also likely to develop cancer in our lifetime.

Some health insurance companies will increase prices gradually as you age - for example, rising health insurance costs each time you renew your policy. Others will charge premiums based on age bands, so you might notice a sudden price rise when you move up to a new band (for instance, from 20-30 years up to 31-40 years).

Why else do health insurance premiums increase?

As well as your circumstances (age, lifestyle and where you live), health insurance costs are also affected by:

Your claims history

If you’ve made a recent claim, you can expect your health insurance premiums to increase at renewal unless your policy is set up using a community rating or pooled risk. If you don’t claim, some insurance companies will give you a no claims discount (similar to car insurance).

Population trends

While it’s good news that most of us are living longer, an ageing population places greater strain on all medical services and provision. Insurance providers must factor this in when determining health insurance rates, which could mean higher premiums for all policyholders.

Inflation

Inflation increases the price of everyday items. This can affect the cost of all hospital services, even if they’re not health-related expenses. For example, increases in the price of food and energy can lead to higher premiums.

Medical inflation

As well as general inflation, healthcare insurance premiums are also affected by medical inflation. This has an impact on healthcare-related costs, such as medical technology, treatments, procedures and even prescription drugs.

It’s worth noting that medical inflation is particularly sensitive to technological improvements. So, while breakthroughs can help cure illnesses and improve overall medical care, the cost of providing those services can increase your health insurance rate.

Insurance premium tax (IPT)

IPT is charged on most insurance products, including private medical cover. It’s currently set at 12% and is usually passed on to you as the policyholder. It means your insurance provider will add 12% to your premium.

Although IPT has stayed the same since 2017, it could rise anytime. Remember that if your base premium rises, adding IPT will increase the overall cost even further.

How can I cut the cost of health insurance premiums as I age?

If you’ve started to notice the cost of private health coverage slowly increasing or you’re thinking about buying a health insurance policy for the first time, here are just a few of the things that you can do to help keep costs down:

1. Consider your policy level and optional extras

Only buy the policy you’re most likely to use. It sounds obvious, but getting carried away with extras is easy. Compare what health insurance options each provider offers and weigh what you’re most likely to need.

2. Increase your excess

Increasing your excess can help reduce your overall insurance premium, but it’s worth checking how your provider charges excess in the first place.

Some insurance providers will only charge you the excess once, no matter how many times you claim within 12 months. Others will charge you for every claim you make, which can add up if you need to make several claims in one year.

It’s also worth checking what happens if your policy’s up for renewal while you’re still having treatment; you may have to claim on your new policy to continue treatment. As this would technically be a new claim under a new policy, you may have to pay the excess again.

3. Maintain good health

You can keep premiums down by maintaining your health, for instance, stopping smoking or cutting down on alcohol. Some providers will even offer discounts if you stay within a healthy weight range.

Other incentives include gym discounts and step monitors with points awarded for meeting goals, which trigger a discount in your premium. Ultimately, the healthier you are, the less likely you are to claim.

4. Choose hospital networks you’ll use

When you choose a health insurance policy, you’ll usually have access to a national network of hospitals, but unrestricted access can be expensive.

Instead, you can limit which hospital network you want any treatment to take place in. For example, if you’d prefer to be treated close to home, you can select your regional network and remove all others.

5. Limit consultant choice

Some providers will let you choose which consultants you see, but this usually comes at a cost. If you don’t mind who you see and simply want to be treated quickly, you can avoid paying more by letting your provider choose for you (you may also be given a list to choose from).

Our guide to reducing health insurance premiums explains more ways to cut the cost of cover, including examples of how much money each method could save you.

How do I choose the right health insurance for me?

The right policy is the one that covers the treatment you’re most likely to need at a price you can keep paying as you get older, so compare the level of cover, the excess, the hospital list and the way each policy is underwritten before you buy.

Health insurance can provide peace of mind, knowing you can avoid lengthy waiting lists should you develop health issues. With so many policies and health insurers, deciding which policy is right for you can take time and effort.

Frequently Asked Questions

What age can you buy private healthcare insurance?

You must be 18 years old to buy a health insurance policy. If you have children, you can add them to your existing plan (which usually means it becomes a family policy).

If you don't already have health cover, you can buy a family health insurance policy. Most insurers cover children until they're 18, or up to 21 if they're in full-time education, and some go further for students.

Is there a maximum age for health insurance?

There's no single maximum age, because several leading insurers, including Aviva, Bupa and Saga, take new members at any age, while others set a limit for new members of between 70 and 85. If you already have a policy, you can usually keep renewing it whatever your age.

Can I buy health insurance if I'm over 65?

You can buy health insurance over 65, although your choice of insurer may be narrower than for someone younger. Several leading insurers, including Aviva, Bupa and Saga, have no upper age limit for new members, while others stop between 70 and 85.

Is a private health insurance plan worth it?

Deciding whether to buy private health insurance is a personal choice, but while medical care is free under the NHS, health insurance provides convenience and offers peace of mind. Not only can you avoid long waiting lists (at the end of August 2026, about 6.2 million people in England were waiting for NHS treatment, according to NHS England), you can decide where you're treated and who by (depending on the level of cover you have).

When you weigh up the pros and cons, it's important to remember that private health insurance policies don't cover emergency treatment, chronic illness or pregnancy (unless there are complications and a risk to the mother's health).
