Key Takeaway

Term assurance covers you for a fixed period (typically 10 to 30 years) and pays out a lump sum if you die during that term. Whole of life insurance covers you for your entire life and is guaranteed to pay out whenever you die. Term policies cost significantly less because they only cover a limited period and many expire without a claim, while whole of life premiums are higher because the insurer will definitely pay out eventually. Most families choose term assurance to cover specific financial responsibilities like a mortgage or dependants’ care during working years.

How Term Assurance Works

Term assurance is the most common type of life cover in the UK. You choose a cover period (the term) and a lump sum amount (the cover). If you die within that term, your beneficiaries receive the full lump sum tax-free. If you survive the term, the policy expires with no payout and no return of premiums.

Two main types exist: level term assurance (the payout stays the same throughout) and decreasing term assurance (the payout reduces over time, often used to match a repayment mortgage balance). According to the Association of British Insurers, term policies are typically used to cover mortgages, replace lost income for dependants, or pay for children’s education costs (ABI, 2026).

Premiums are fixed for the term and are comparatively affordable. A healthy 35-year-old might pay £15 to £25 per month for £200,000 of level term cover over 25 years (as of July 2026; verify current premiums with an FCA-authorised adviser or insurer before deciding).

How Whole of Life Insurance Works

Whole of life insurance has no fixed end date and covers you for your entire life. The policy guarantees a payout whenever you die, provided premiums are kept up to date. This makes it significantly more expensive than term assurance because the insurer knows a claim will eventually occur.

Whole of life policies often build a cash value over time (known as an investment element), though this varies by policy type. Some policies have reviewable premiums that may increase as you age, while others have fixed premiums set at the outset. MoneyHelper notes that whole of life cover is commonly used for inheritance tax planning, to cover funeral costs, or to leave a guaranteed sum to beneficiaries (MoneyHelper, 2026).

Monthly premiums for whole of life cover are substantially higher than term assurance. The same 35-year-old might pay £80 to £150 per month or more for £200,000 of whole of life cover, depending on the policy structure and whether premiums are fixed or reviewable.

Cost Comparison and Trade-Offs

The fundamental trade-off is certainty versus cost. Term assurance is cheaper because it may never pay out, most policyholders outlive their term and the insurer keeps the premiums. Whole of life is more expensive because the insurer will definitely pay the claim eventually.

For families with dependants, a mortgage, or time-limited financial responsibilities, term assurance usually provides better value. You pay for cover only during the years your family would struggle financially without your income. Which? consumer research consistently shows that term policies offer the most cost-effective protection for working-age families with specific responsibilities (Which?, 2026).

Whole of life suits different goals: covering a guaranteed liability like inheritance tax, leaving a legacy regardless of when you die, or funding funeral costs. If you have no specific end date for the financial need, whole of life may be appropriate, but the higher cost means smaller sums of cover for the same monthly budget.

Which Policy to Choose

Choose term assurance if you need to cover a mortgage, replace income for dependants, or protect your family during your working years. Match the term to your longest financial responsibility (for example, until your youngest child finishes education or your mortgage is repaid). Decreasing term works well for repayment mortgages; level term suits income replacement or other fixed liabilities.

Choose whole of life if you want to leave a guaranteed inheritance, cover a known future cost like inheritance tax, or ensure funeral expenses are covered whenever you die. Whole of life is also used in trust planning to pass wealth outside your estate.

Many people combine both: a large term policy for family protection during working years, plus a smaller whole of life policy for funeral costs or inheritance. An FCA-authorised insurance adviser can help you model your specific needs and compare costs.
