Term Life Insurance vs Whole Life Insurance UK 2026: Which Should You Buy?
Term life insurance covers you for a fixed period at a low premium and pays out only if you die within that term. Whole-of-life insurance covers you forever and guarantees a payout whenever you die, at a much higher cost. Choosing the right one depends on whether you are protecting a temporary need — like a mortgage or young family — or a permanent one, like an Inheritance Tax bill or funeral costs.
TL;DR - 30-Second Summary
- - Term life: cheap, fixed period, pays out only if death occurs within the term, no cash value
- - Whole life: covers you forever, guaranteed payout, premiums 5–10x higher for the same sum assured
- - Best fit: term for mortgages and family protection; whole-of-life for IHT planning and funeral costs

What Is Term Life Insurance?
Term life insurance provides cover for a set number of years and pays a tax-free lump sum (or, with family income benefit, a regular income) if you die during that term. If you outlive the term, the policy simply ends with no payout and no refund of premiums. Because most policies never pay out, premiums are relatively low, making term the most common form of life cover in the UK.
Level termkeeps the sum assured constant throughout the policy — useful for family income replacement or interest-only mortgages. Decreasing term reduces the sum assured over time to mirror a repayment mortgage balance, and is the cheapest option purely for mortgage protection.
What Is Whole Life Insurance?
Whole-of-life insurance guarantees a payout whenever you die, provided premiums are kept up. Because the insurer knows a claim is certain eventually, premiums are much higher for the same cover level than an equivalent term policy, and they are usually fixed for life or reviewed periodically depending on the product.
Guaranteed whole-of-life plans (often marketed as over-50s life cover or IHT protection plans) are common for older applicants and estate planning, while investment-linked or with-profits whole-of-life policies combine protection with an investment element, though these are less common for new business today.
Using Life Insurance for Inheritance Tax Planning
With the Inheritance Tax nil-rate band frozen at £325,000 and the residence nil-rate band at £175,000 in 2026/27, estates above these combined thresholds face a 40% tax charge. Because a whole-of-life policy is guaranteed to pay out eventually, it is commonly written in trust specifically to provide the cash needed to settle an expected IHT bill without forcing beneficiaries to sell a property or other illiquid assets.
A term policy is not suitable for this purpose unless the IHT liability itself is expected to fall away within a fixed period — for example, cover matched to the seven-year taper on a potentially exempt transfer.
Who Should Choose What?
- - You have a mortgage or young children to protect for a set number of years
- - You want the lowest premium for a given sum assured
- - Your protection need will reduce or end (e.g. mortgage repaid, children independent)
- - You are planning to cover an Inheritance Tax bill
- - You want to guarantee funeral costs or a fixed legacy regardless of when you die
- - You can afford the significantly higher premium for lifelong certainty
Many households combine both: decreasing term cover for the mortgage years, plus a smaller whole-of-life policy in trust for a guaranteed legacy or IHT provision.
