What is level term life insurance?

Level term life insurance pays a fixed lump sum — the same amount regardless of when during the policy term a claim is made. If you take out a £300,000 level term policy and die in year 2 or year 28, your beneficiaries receive £300,000.

What is decreasing term life insurance?

Decreasing term life insurance pays a lump sum that reduces over time — typically designed to mirror a repayment mortgage. The payout is highest at the start of the policy and reduces each year, reaching approximately zero at the end of the term.

Quick guide: If your main goal is to clear a repayment mortgage, decreasing term is cheaper and purpose-built for this. If you want to replace your income or leave a flexible sum for your family, level term is better.

Which is better — level or decreasing?

It depends on your primary reason for buying life insurance:

  • Choose decreasing term if: you mainly want to clear your repayment mortgage and your other financial needs are modest
  • Choose level term if: you want to replace your income for your family, you have an interest-only mortgage, or you want maximum flexibility with the payout
  • Consider both: many people have a decreasing term policy to cover their mortgage and a level term policy to replace their income — giving comprehensive cover at a combined cost that's often still competitive

Can I have both?

Yes — you can hold multiple life insurance policies. A decreasing term policy to track your mortgage balance, plus a level term policy for income replacement, is a popular combination that provides comprehensive protection.

Frequently Asked Questions

Yes — for people whose primary goal is mortgage protection on a repayment mortgage. It's typically 20–35% cheaper than level term and is perfectly aligned to reducing mortgage debt.

Not on an existing policy — you would need to take out a new level term policy. You can keep both running simultaneously if you want to upgrade your cover.
