Life insurance and mortgage protection are two names for closely related products, and clients regularly buy one when they wanted the other. Here is the plain difference, when each one is right, and how to think about it in five minutes.

The one-line difference

Mortgage protection is a form of life insurance sized to clear your mortgage. Life insurance (in its wider sense) is sized to look after your family generally — which might mean clearing the mortgage and replacing income for years afterwards.

Every mortgage protection policy is a life policy. Not every life policy is a mortgage protection policy.

Level term vs decreasing term

The mechanical difference is usually about how the payout changes over time:

  • Decreasing term (typical mortgage protection): the sum insured reduces year by year, matching a repayment mortgage. When the mortgage is paid off, the policy ends. Cheapest option.
  • Level term (typical wider life cover): the sum insured stays the same for the whole policy term. More expensive because the average payout is higher.

On the same £250,000 sum insured over 25 years, level term costs roughly 1.5x to 2x what decreasing term costs, because a claim in year 20 pays out the full £250,000 rather than the remaining mortgage balance.

When mortgage protection alone is enough

  • You have no dependants and no one relies on your income.
  • Your only significant debt is the mortgage.
  • Your partner earns enough independently to run the household without your income.

When you need wider life cover

  • You have children whose upbringing depends on your income continuing.
  • Your partner would struggle to cover household running costs without you.
  • You want to leave something behind beyond simply clearing the mortgage.

The sensible middle ground

For most young families, the right answer is often mortgage protection plus family income benefit:

  • Decreasing term mortgage protection to clear the £250,000 mortgage.
  • Family income benefit paying £2,500 a month to your partner and children for the next 20 years.

This combination gives your family a paid-off house and a monthly income to run the household. It is usually noticeably cheaper than trying to do the same job with a single large lump-sum policy.

Two things people miss

1. Write it in trust

Whichever type of policy you take, ask us to write it in trust for you. A policy in trust pays out directly to your beneficiaries in weeks (not months waiting for probate) and usually sits outside your estate for inheritance tax purposes. It costs nothing extra.

2. Joint life first-event pays out once

A joint-life policy pays out on the first death, then the policy ends. The survivor no longer has cover. For most married couples with a shared mortgage this is fine, but if you both have serious dependants (say from previous relationships) two single-life policies may be a better structure. We compare both on quotes.
