Quick Answer: What Is Term Life Insurance?
Term life insurance covers you for a fixed period — the “term”, such as 20 or 30 years. If you die during that term, it pays a tax-free lump sum to your beneficiaries; if you outlive it, the policy simply ends with no payout. Because it only covers a set period, it’s the cheapest and most popular type of UK life insurance — for many healthy applicants, just a few pounds a month.
There are three main flavours: level (fixed payout, good for family cover), decreasing (falls over time, tracks a repayment mortgage, cheapest), and increasing (rises with inflation). Below we cover each, how much you need, cost, and how it compares to whole of life. Ready to compare? Start here.
What this guide covers
What Is Term Life Insurance?
Term life insurance is the most straightforward form of life cover: you’re insured for a defined number of years, and if you die within that window, your family receives a tax-free lump sum. It’s designed to cover the years when other people depend on you financially — while you have a mortgage, or children at home — rather than for your whole life.
That focus is exactly why it’s so affordable: the insurer is only covering a fixed, finite period. It’s the default choice for most UK families and the natural starting point when you’re working out how life insurance works.
ℹ️ Term vs whole of life, in one line
Term life covers a set period and is cheap; whole of life covers you forever and guarantees a payout, but costs considerably more. Most people choose term because it matches a real need (a mortgage, dependent children) at the lowest cost. More on the permanent option in whole of life explained.
How Term Life Insurance Works
- Choose your cover amount (the sum assured) and term length (e.g. 25 years)
- Answer health and lifestyle questions — this underwriting sets your premium
- Pay a fixed monthly premium for the term (guaranteed premiums stay level)
- If you die during the term, your beneficiaries claim the tax-free lump sum
- If you outlive the term, the policy ends — no payout, no refund
Being honest on the application is essential — non-disclosure is the main reason claims are declined. See what life insurance doesn’t cover, and how cover works if you’re a smoker or have diabetes or high blood pressure.
Level vs Decreasing vs Increasing Term
The one decision that trips people up. All three are “term” policies — the difference is what happens to the payout amount over time:
| Type | Payout over time | Best for | Cost |
|---|---|---|---|
| Level term | Stays the same | Family protection, interest-only mortgage | Moderate |
| Decreasing term | Reduces over time | Repayment mortgage (tracks the balance) | Cheapest |
| Increasing term | Rises (often with inflation) | Protecting the real value of cover | Highest |
Decreasing term is the classic mortgage companion — as your repayment mortgage shrinks, so does the cover you need, which keeps it cheap. See life insurance and mortgages and provider mortgage cover from Aviva, Legal & General and Vitality. Level term suits family income protection where you want a fixed sum whatever happens. You can also add critical illness cover to a term policy.
How Long Should the Term Be?
Match the term to what you’re protecting — the responsibility should end around the same time the policy does:
- Mortgage: set the term to the years left on the loan (e.g. 25-year mortgage → 25-year term)
- Family protection: cover until your youngest child is financially independent — often 18–25 years
- Income replacement: align with your expected retirement, when your salary would stop anyway

How Much Cover Do You Need?
A common rule of thumb is 10× your annual income, but it’s better to add up what you’re actually protecting:
- Outstanding mortgage and any other debts
- Income replacement for the years your family would need it
- Childcare and education costs
- Minus any existing cover (e.g. death-in-service from an employer)

What Does Term Life Insurance Cost?
Term life is the cheapest form of life cover — for many healthy younger applicants, just a few pounds a month. Your premium depends on:
Lowers your premium
- Being younger and in good health
- Non-smoker status
- Decreasing term (vs level)
- A shorter term / lower cover amount
Raises your premium
- Older age at application
- Smoking or vaping
- Health conditions (diabetes, high BP)
- Adding critical illness cover
The single biggest lever is buying young — premiums rise with age, so locking in early is usually cheaper over a lifetime. The only accurate figure is a personalised quote; compare providers via the best UK life insurers or the life insurance hub.

Term vs Whole of Life Insurance
The two are built for different jobs:
| Term life | Whole of life | |
|---|---|---|
| Covers | A fixed period | Your whole life |
| Pays out | Only if you die in the term | Guaranteed, whenever you die |
| Cost | Much cheaper | Significantly higher |
| Best for | Mortgage, family, income | Inheritance, funeral, IHT |
Most UK buyers choose term for affordability and because their need is time-limited. Whole of life makes sense if you specifically want a guaranteed payout — for example to help with inheritance tax or funeral costs. Full detail in whole of life explained, and the naming quirk in life assurance vs life insurance.
Who Is Term Life Insurance For?
Term suits anyone with a time-limited financial responsibility. Common examples:
- Parents — cover until the kids are independent
- Couples — protect a shared mortgage (joint or two single policies)
- Mortgage holders — decreasing term to match the loan
- Self-employed — no employer death-in-service to fall back on
- Single people with a mortgage or dependants
- After divorce — to secure maintenance or children’s costs
Older applicants past the typical term window may prefer over-50s or over-60s plans. Business owners should look at relevant life insurance.
Frequently Asked Questions
What is term life insurance?
Term life insurance covers you for a fixed period — the ‘term’ — such as 20 or 30 years. If you die during that term, it pays a tax-free lump sum to your beneficiaries. If you outlive the term, the policy simply ends with no payout. Because it only covers a set period, term life is usually the cheapest type of life insurance and is the most popular choice in the UK.
What’s the difference between level and decreasing term?
Level term pays out the same fixed amount whenever you die during the term — ideal for family protection or an interest-only mortgage. Decreasing term has a payout that reduces over time, designed to track a repayment mortgage as the balance falls, and is usually cheaper. Increasing term rises over time, often in line with inflation, to protect the real value of your cover.
How long should the term be?
Match the term to what you’re protecting. For a mortgage, set it to the years left on the loan. For family protection, a common approach is to cover until your youngest child is financially independent, often 18 to 25 years. Some people align the term with their expected retirement. The key is that the term lasts as long as the financial responsibility you’re covering.
How much does term life insurance cost?
Term life is the cheapest form of life cover and for many healthy younger applicants can cost just a few pounds a month, though the price depends on your age, health, whether you smoke, the cover amount and the term length. Decreasing term is generally cheaper than level term. The only accurate figure is a personalised quote, and buying younger and healthier usually locks in a lower premium.
Is term or whole of life insurance better?
It depends on your goal. Term life is cheaper and suits a defined need such as a mortgage or raising children, but pays out only if you die within the term. Whole of life is more expensive but guarantees a payout whenever you die, making it suited to leaving an inheritance or covering funeral or inheritance tax costs. Most UK buyers choose term for affordability.
What happens when the term ends?
If you’re still alive when the term ends, the policy simply stops and there is no payout or refund of premiums — term life has no cash value. If you still need cover, you can take out a new policy, though it will be priced at your older age and current health. Some policies offer a guaranteed insurability or renewal option, which is worth checking when you buy.
Can I have more than one term life policy?
Yes. Many people hold more than one policy — for example, a decreasing term policy to cover the mortgage plus a separate level term policy for family income. This ‘layering’ can be more flexible and sometimes cheaper than one large policy, and lets cover end at different times as needs change. Each policy is underwritten and priced separately.
