Term vs whole life insurance: which type of life cover do you need?

Term life insurance pays out a tax-free lump sum if you die during a specified term — for example, 20 or 30 years. If you outlive the policy, it ends with no payout and no return of premiums. There are several types of term insurance: level term — the sum assured and premiums remain constant throughout the term, suitable for covering a fixed mortgage or known financial obligation; decreasing term — the sum assured decreases over time, typically used to cover a repayment mortgage; and increasing term — the sum assured increases annually to keep pace with inflation. Term insurance is significantly cheaper than whole life insurance because the insurer only pays out if you die during the policy term, which for most healthy people in their 30s and 40s is statistically less likely than not.

Whole life insurance guarantees a payout whenever you die, making it both an insurance product and a savings vehicle. Because the payout is guaranteed (provided premiums are maintained), insurers invest the premiums and build up a cash value over time. This makes whole life insurance significantly more expensive than term insurance — typically 5-10 times the cost of equivalent term cover. Whole of life policies are sometimes used for estate planning purposes, particularly to cover the inheritance tax liability on larger estates, because the payout can be structured to be held outside the estate. However, for most families, the high cost of whole life insurance makes it a poor choice compared to investing the difference in a diversified portfolio or pension.

For the vast majority of UK families, term life insurance is the right choice. It is cheaper, simpler, and more appropriate for the financial protection purpose that life insurance serves. The key question is: what are you protecting? If you want to ensure your family can pay off the mortgage if you die, a decreasing term policy matching your mortgage term is ideal. If you want to provide income replacement and financial security for your family, a level term policy for 20-30 years is appropriate. Whole life insurance makes sense in very specific circumstances: when estate planning is the primary goal, when you have been declined for term insurance due to health conditions, or when you need to cover a specific liability that extends indefinitely. In most cases, a combination of term life insurance, income protection, and a healthy emergency fund provides better protection than whole life insurance at a fraction of the cost.
