When you take out life insurance in the UK, one of the first decisions you will face is whether to choose decreasing term or level term cover. The distinction is straightforward but consequential: one pays a fixed lump sum throughout the policy term, while the other reduces over time to mirror a specific financial obligation. Getting this choice right from the outset means your cover is correctly matched to what you are actually trying to protect.
What Is Level Term Life Insurance?
Level term life insurance pays a fixed sum assured if you die within the agreed policy term. The amount your beneficiaries receive is the same whether you die in year one or year nineteen of a twenty-year policy. The monthly premium is also fixed for the duration of the term, so there are no surprises.
This type of cover is primarily used where the financial obligation being protected does not decrease over time. Common applications include:
- Replacing a salary or income for dependants over a set number of years
- Covering an interest-only mortgage, where the outstanding balance does not reduce
- Providing a lump sum for children’s education or future financial security
- Covering a fixed liability such as a business loan that does not reduce in line with a repayment schedule
What Is Decreasing Term Life Insurance?
Decreasing term life insurance also runs for a fixed period, but the sum assured reduces throughout the term, typically in line with the outstanding balance on a repayment mortgage. If you die in year one, the payout is close to the original sum insured. If you die in year nineteen of a twenty-year policy, the payout is much smaller, reflecting the fact that the mortgage balance has been substantially reduced by years of repayments.
Decreasing term policies are specifically designed for repayment mortgages. They are not suitable for interest-only mortgages, where the capital balance remains constant throughout the mortgage term.
Because the potential payout reduces over time, decreasing term insurance is cheaper than an equivalent level term policy. The insurer’s risk diminishes as the policy matures, and this is reflected in the premium.
Cost Comparison
As a general principle, decreasing term cover costs less per month than level term cover for the same initial sum assured and policy term. The exact difference depends on age, health, the insurer, and the specific terms of the policy. For a repayment mortgage, this makes decreasing term cover attractive because the payout is designed to track the debt, meaning you are not paying for cover that exceeds your actual need.
However, the cheapest option is not always the most appropriate one. If you have dependants who would also need financial support beyond the mortgage repayment, level term cover may be more appropriate even though the premium is higher.
Which Is Right for You?
Choose decreasing term if:
- You have a repayment mortgage and your primary goal is to ensure it is paid off if you die
- Budget is a key consideration and you want the most cost-effective mortgage protection
- You have separate life insurance in place to cover income replacement or other needs
Choose level term if:
- You have an interest-only mortgage where the balance does not reduce
- You want to provide a fixed lump sum for your family regardless of when you die
- You are primarily focused on income replacement rather than mortgage repayment
- You want flexibility for your beneficiaries to use the payout as they see fit
It is also possible to hold both types simultaneously. Some people take out decreasing term cover to protect their mortgage and a separate level term policy to cover income replacement, business obligations, or a lump sum for their family. There is no rule against holding more than one life insurance policy.
Policy Term Considerations
Whichever type you choose, the policy term should align with the financial obligation you are protecting. For mortgage protection, the term should match the remaining term of your mortgage. For income replacement, the term is often chosen to run until the youngest child is financially independent, or until the policyholder’s intended retirement age.
Both types of policy pay out a lump sum if you die within the term. Neither has a cash value at the end if no claim is made, and neither provides any return on premiums paid. They are pure protection products, not savings or investment vehicles.

Frequently Asked Questions
Can I change from decreasing term to level term part way through my policy?
Changing the type of policy mid-term is not generally possible. If your circumstances change and you need a different type of cover, you would need to take out a new policy. A broker can help you assess whether it makes sense to keep your existing policy and add a new one alongside it.
Does decreasing term insurance track my exact mortgage balance?
Decreasing term policies reduce according to a fixed schedule built into the policy, typically matching a standard repayment mortgage at a specified interest rate. They do not read your actual mortgage balance in real time. If your mortgage rate or term changes significantly, it is worth reviewing whether your cover still aligns with your outstanding debt.
Is decreasing term insurance suitable for an interest-only mortgage?
No. On an interest-only mortgage, the capital balance does not reduce during the mortgage term, so a decreasing sum assured would leave a shortfall. Level term insurance is the appropriate choice for an interest-only mortgage, as the payout remains constant throughout the term.
What happens if the decreasing term policy pays out less than the remaining mortgage balance?
This could occur if the policy was not set up to correctly match the mortgage from the start, or if the mortgage has been restructured. It is important to ensure that the initial sum assured and the reduction schedule are appropriate for your specific mortgage when the policy is taken out. A broker can help ensure the two are properly aligned.
