What Is the Difference Between Term and Whole of Life Insurance?
When you start looking at life insurance in the UK, you will quickly encounter two fundamental categories: term life insurance and whole of life insurance. Although both pay a lump sum to your beneficiaries when you die, they work in very different ways and serve different purposes.
Term life insurance is the most popular type of life cover in the UK. It covers you for a specific period – typically 10 to 40 years – and only pays out if you die during that time. Level term cover averages £25.05 per month, making it affordable for most families. If you survive the term, the policy ends and no payout is made.
Whole of life insurance, by contrast, has no expiry date. It covers you for your entire life and guarantees a payout whenever you die. This certainty comes at a significantly higher price, with average premiums of around £102 per month. Whole of life policies are often used for inheritance tax planning (IHT is charged at 40% on estates above £325,000), leaving a legacy, or ensuring funeral costs are covered regardless of when death occurs.
How Does Term Life Insurance Work in the UK?
Term life insurance is the simplest and most widely purchased form of life cover in the UK. You choose a sum assured (the amount your family would receive), a policy term (how many years the cover lasts), and begin paying fixed monthly premiums. If you die within the term, your insurer pays the full sum assured to your nominated beneficiaries.
The key feature of term insurance is that premiums are locked in at the point of purchase. A healthy 30-year-old who takes out a 25-year policy will pay the same monthly premium in year one as in year twenty-five. This predictability makes budgeting straightforward. To understand what drives premiums, see our life insurance cost guide.
Level Term Insurance
Level term keeps the same payout throughout. If you take out £300,000 of cover, your family receives £300,000 whether you die in the first year or the last. This is ideal for general family protection and income replacement, where the financial need does not decrease over time.
Decreasing Term Insurance
Decreasing term sees the payout reduce over time, typically in line with a repayment mortgage balance. Because the insurer's maximum liability falls each year, premiums are lower than level term. This is the most cost-effective way to protect a repayment mortgage. See our mortgage life insurance guide for more detail.
Family Income Benefit
Family income benefit (FIB) is a variant of term insurance that pays a regular monthly income rather than a lump sum. Payments continue from the date of your death until the end of the policy term. FIB is often cheaper than equivalent level term cover and can be easier for families to manage day-to-day.
How Does Whole of Life Insurance Work?
Whole of life insurance guarantees a payout whenever you die. There is no fixed term, so the policy remains active as long as you continue paying premiums. This guarantee of a payout makes whole of life considerably more expensive than term insurance.
Some whole of life policies are straightforward: you pay a fixed premium, and a guaranteed sum is paid upon your death. Others include an investment element, where part of your premium is invested in funds managed by the insurer. These unit-linked policies can build a cash value over time, but the investment element introduces an element of risk.
The Investment Element
Unit-linked whole of life policies split your premium between the cost of life cover and an investment fund. If the fund performs well, the policy's cash value grows and may exceed the sum assured. If the fund performs poorly, you may face increased premiums or reduced cover at the next review point, which typically occurs every ten years.
Standard or guaranteed whole of life policies do not carry this investment risk. You pay a fixed premium for a guaranteed payout. These are more predictable but offer no potential for growth.
How Much Does Term vs Whole of Life Insurance Cost?
The cost difference between term and whole of life insurance is substantial. Average level term premiums are £25.05 per month, while whole of life insurance averages around £102 per month – roughly four times the price. The table below illustrates typical monthly costs for a 35-year-old non-smoker in good health.
| Policy Type | Sum Assured | Term / Duration | Approx. Monthly Cost |
|---|---|---|---|
| Level Term | £250,000 | 25 years | £10 – £18 |
| Decreasing Term | £250,000 (initial) | 25 years | £7 – £13 |
| Family Income Benefit | £2,000/month | 25 years | £9 – £16 |
| Whole of Life (guaranteed) | £250,000 | Lifetime | £120 – £200 |
| Whole of Life (reviewable) | £250,000 | Lifetime | £80 – £150* |
| Over 50s Plan | £5,000 – £25,000 | Lifetime | £10 – £50 |
*Reviewable premiums may increase substantially at review points. Figures are illustrative and based on a 35-year-old non-smoker in average health.
When Is Term Life Insurance the Better Choice?
For the majority of UK families, term life insurance is the right choice. It provides the highest level of cover for the lowest cost, and it aligns with the period when financial protection is most needed. Term insurance is typically better when:
- You have a mortgage – Decreasing term cover mirrors your repayment mortgage and is the most cost-effective option.
- You have dependent children – Level term or FIB covers the years until your children are financially independent. Read more in our life insurance for parents guide.
- You are on a budget – Term premiums are a fraction of whole of life costs, making comprehensive cover accessible.
- You want simplicity – Term policies are straightforward with no investment complexities.
- You need cover for a specific debt – Any time-limited financial obligation is best matched with term cover.
When Is Whole of Life Insurance Worth It?
Whole of life insurance serves specific purposes where a guaranteed, lifelong payout is essential. It is typically the better option when:
- Inheritance tax planning – If your estate will exceed the IHT threshold (40% tax on everything above £325,000, or £500,000 with the residence nil-rate band), a whole of life policy written in trust can provide the funds to pay the tax bill without your beneficiaries having to sell assets.
- Leaving a guaranteed legacy – If you want to leave a specific sum to your children or a charity, whole of life guarantees that money will be available.
- Funeral costs – A smaller whole of life policy (or an over 50s plan) ensures funeral expenses are covered without burdening your family.
- Lifelong dependants – If you care for a disabled child or adult who will always depend on financial support, whole of life ensures provision regardless of when you die.
Over 50s Life Insurance Plans
Over 50s plans are a simplified type of whole of life insurance aimed at people aged 50 to 85. They require no medical examination and acceptance is guaranteed, making them accessible to people who might struggle to get standard cover. However, the sum assured is typically much lower – usually between £1,000 and £25,000.
These plans are primarily used to cover funeral costs, leave a small gift to family, or pay for end-of-life expenses. A key consideration is that if you live for many years after taking out the policy, you may end up paying more in premiums than the policy will pay out. For more detail, see our over 50s life insurance guide.
Can You Have Both Term and Whole of Life Insurance?
Yes, and many people do. A common and effective strategy is to use term insurance for your large, time-limited protection needs (mortgage, children's dependency years, income replacement) and a smaller whole of life policy for guaranteed needs like funeral costs or a legacy gift. There is no limit to the number of life insurance policies you can hold, and all valid claims will be paid independently.
This combined approach gives you comprehensive protection at a much lower total cost than relying on whole of life insurance alone. It also means your cover adapts to your changing needs over time.
