Average Cost of Life Insurance in the UK: What Affects It?
Published Updated
How much does life insurance cost per month in the UK? It depends on the person, the policy and the cover requested. Two people asking for £200,000 of life insurance could be quoted very different monthly premiums because they have different ages, health histories, nicotine use, policy terms or benefits.
You’ll see adverts for life insurance starting from a few pounds a month. Those are examples of cover available under particular conditions, not a typical price you can assume you will qualify for. A personalised quotation is much more useful than a single national “average”.
What makes life insurance cheaper or more expensive?
| Factor | Why it affects the price |
|---|---|
| Age when the policy starts | The premium offered for new cover will normally reflect the applicant’s age and the insurer’s risk assessment. |
| Health and medical history | Some conditions require additional evidence, a different premium or other terms. Insurers do not all make identical decisions. |
| Smoking and nicotine use | Insurers ask about smoking and often other nicotine products. Their definitions and eligibility rules vary. |
| Amount of cover | A larger insured benefit will generally cost more, everything else being equal. |
| Length of term | Longer protection can cost more than a shorter policy, although actual insurer pricing varies. |
| Type of policy | Level term, decreasing term, family income benefit and whole-of-life insurance serve different needs and are not directly comparable on price alone. |
| Additional benefits | Critical illness, premium waiver and other features may affect the cost and conditions. |
MoneyHelper’s life insurance guide identifies the main factors affecting price and recommends comparing suitable quotations.
Illustrative life insurance costs over 20 years
It helps to understand how even a small premium difference adds up. The figures below are arithmetic examples only, not insurer quotations. They assume the monthly payment stays exactly the same for 20 years, with no premiums missed and no mid-term changes.
| Illustrative monthly premium | Total over 10 years | Total over 20 years |
|---|---|---|
| £10 | £1,200 | £2,400 |
| £15 | £1,800 | £3,600 |
| £20 | £2,400 | £4,800 |
| £30 | £3,600 | £7,200 |
These totals don’t tell you whether any particular person can obtain that premium—or whether the cover would be suitable. For example, a £15 monthly policy with weaker or different protection may be poorer value than a £20 policy that addresses the actual risk you want to insure.
Is a £100,000 policy cheaper than £250,000 of cover?
Often, yes. The amount insured is one of the core price factors, but the relationship isn’t a simple fixed price per £1,000. Insurers use their own premium calculations, minimum premiums and underwriting rules. It is better to request illustrations for several sensible amounts on the same basis than rely on a generic table.
Work out your starting figure by considering the outstanding mortgage, household bills, childcare or dependent family costs, and existing savings or protection. Our guide to choosing a cover amount explains that process with an example.
How does age affect the monthly premium?
New cover is generally more expensive to arrange as you get older, all other things being equal. But a 40-year-old with one set of health and cover requirements cannot be compared directly with a 35-year-old requesting a different policy.
If you already have an appropriate fixed-premium policy, don’t assume that taking out a new one will save money. Reapplying means your current age and health are assessed. Never cancel existing cover just because a new indicative price looks cheaper; make sure suitable replacement cover is in force first.
How much does smoking change the price?
Smoking is a meaningful underwriting factor, but there is no universal smoker surcharge across all providers. The questions can include cigarettes, vaping and other nicotine products, and there may be rules for former smokers. Answer the insurer’s questions fully and accurately; what counts as a non-smoker for one company may not match another company’s criteria.
Does medical history affect life insurance prices?
It can. An insurer may offer ordinary terms, request a GP report, charge more or decline a particular application. Decisions depend on the type and history of the condition and other risk factors. For example, someone with diabetes may need a different underwriting approach from somebody without that medical history, but a diagnosis alone does not establish the exact premium or result.
See our broader life insurance with health conditions guide for the usual application process.
Level term versus decreasing term: which costs less?
For otherwise comparable policies, decreasing cover can be cheaper because the insured amount reduces according to a policy schedule. That can make it worth considering for a repayment mortgage. Level term cover maintains a fixed benefit and may better suit needs that do not shrink in the same way, such as replacing family income or protecting an interest-only mortgage.
The cheapest product isn’t automatically the correct one. Compare our level term guide with the decreasing term guide to understand the distinction.
What should you compare between two life insurance quotations?
- The same starting amount of cover, policy term and level or decreasing benefit structure.
- Guaranteed or reviewable monthly premiums, and any options to increase cover or premiums.
- Whether the illustrations include critical illness, waiver of premium or any other extra benefits.
- Underwriting assumptions and whether the insurer has accepted the application at the quoted price.
- Terminal illness provisions, exclusions, eligibility and how a claim would be dealt with.
- Whether a joint policy or two single-life policies would better suit the household.

How can you avoid overpaying for cover?
Start with a realistic protection need, compare quotations on equivalent terms, and check what you already have through work. For example, death-in-service cover may reduce the additional amount your family needs, although it can end when you leave that employer. If you already hold protection, review it before buying something new rather than duplicating benefits automatically.
If budget is tight, think about what you most need to protect first. Having the right type and duration of cover matters more than chasing an attractive headline price. MoneyHelper’s protection guide also explains the value of prioritising essential needs.
