Life insurance

Level vs decreasing term life insurance: what’s the difference?

The short answer

Both are term policies, but a level term sum assured stays fixed for the whole term, while a decreasing term sum falls over the years, broadly tracking a repayment mortgage balance. Because the insurer’s potential liability shrinks each year, decreasing term costs less for the same starting figure.

What the contract actually does

Life insurance is a contract between you and an insurer. In exchange for the premium, the insurer agrees to pay the sum assured if you die while the cover is in force. The money goes to your estate by default, or to trustees for named beneficiaries if the policy is written in trust. There is no savings element in standard term cover: if the policy ends without a claim, nothing is returned. Before you buy, the FCA’s conduct rules require the insurer to give you pre-contract information — the Insurance Product Information Document and the full wording — and a statutory cancellation period afterwards. [3]

Two structural points shape everything else. First, the type of cover decides whether a pay-out is possible or certain: term assurance pays only if you die inside the term, while whole of life cover has no end date and must pay eventually. Second, the premium reflects the risk the insurer is taking on you — your age, health, smoking status and the size and length of cover — which is why two people quoted for the same sum assured can be offered very different prices. The FCA’s Consumer Duty requires insurers to design, price and explain products to deliver good outcomes for retail customers. [4] This guide stays on the difference between level and decreasing term cover.

The main types of life cover

Level term assurance pays a fixed sum if you die within the term. Decreasing term assurance lets the sum fall over the years, usually tracking a repayment mortgage, and is cheaper for the same starting figure. Whole of life assurance has no term at all and costs substantially more, because the pay-out is certain rather than possible. Guaranteed-acceptance over-50s plans trade medical questions for small, capped sums and an initial qualifying period. The ABI and GRiD track life insurance, income protection and critical illness as distinct claim types in their annual pay-out data — a reminder that “protection” is a family of different contracts, not one product. [10] None of these products builds a savings pot you can draw on; if you are offered a life policy with an investment element, that is a different and more complex contract — check the firm is authorised on the Financial Services Register and read the charges disclosure carefully. [2]

Thinking about the difference between level and decreasing term cover

What works well

  • Decreasing term matches a repayment mortgage cheaply.
  • Level term suits needs that do not shrink, like family income.
  • The structure choice is visible in the illustration before you buy.

What to watch

  • The decrease rate may not match your actual mortgage rate.
  • Decreasing cover leaves nothing over once the mortgage is cleared.
  • A level sum loses real value to inflation over long terms.

Your disclosure rights

The Consumer Insurance (Disclosure and Representations) Act 2012 replaced the old duty to volunteer everything with a duty to take reasonable care to answer the insurer’s questions accurately and not to mislead. [6] The Insurance Act 2015 added proportional remedies: an insurer that would have offered cover on different terms must apply those terms rather than refusing the claim outright, unless the misrepresentation was deliberate or reckless. [7] The Ombudsman’s published decisions show both statutes being applied to real declined life claims — including a voided policy where the insurer’s handling was upheld, and a terminal-illness claim turned down on a qualifying misrepresentation. [9][11] This matters enormously for life cover, because a claim is tested against answers given years — sometimes decades — earlier.

Alongside the statutes, the FCA’s conduct rules require insurers to give you the product information document and full wording before you buy, and to handle claims and complaints fairly. [3] The Consumer Duty sits above all of it: insurers and intermediaries must act to deliver good outcomes for retail customers, covering how products are designed, priced, explained and serviced. [4] You can check that any insurer, adviser or broker you deal with is authorised on the Financial Services Register. [2]

A fixed promise versus a shrinking one

A level term policy promises the same sum in year one as in the final year, which suits obligations that do not shrink: family income, childcare costs, an interest-only mortgage. A decreasing term policy promises a sum that falls on a set schedule, designed to shadow a repayment mortgage as monthly payments erode the balance. The design assumption matters: the policy’s decrease rate assumes a mortgage interest rate, and if your actual mortgage rate runs higher, the cover can fall faster than the debt — a gap worth checking on the policy illustration. For anything other than a repayment mortgage, level cover is usually the honest structure, because most family needs do not shrink on a schedule. Inflation also works on a level sum over a long term, which is why some policies offer an increasing or index-linked option at higher cost [SOURCE REQUIRED: insurer illustration of decrease-rate assumptions].

If the cover is for a repayment mortgage, ask for the policy’s assumed decrease rate and compare it with your actual mortgage rate before buying. Whatever the specifics of the difference between level and decreasing term cover, the discipline that protects your family is always the same: get the insurer’s position in writing, keep the documents with the policy, and make sure the people who would claim know the policy exists and where the paperwork lives.

What moves the price

Life insurance premiums are set at the outset from your age, your answers on health and lifestyle — smoking status is one of the largest single factors — the sum assured, the length of cover and the premium type. Guaranteed premiums stay fixed for the term; reviewable premiums can be re-priced by the insurer at set intervals, which makes a cheaper starting quote expensive later. Average premium figures circulate widely online, but an average built from different ages, health profiles and cover amounts cannot predict your quote — treat any average without a named source and a date as unusable [STATISTIC REQUIRED: current average UK life insurance premium, named source].

One genuine lever does exist beyond the cover design itself: the underwriting outcome. Two insurers can assess the same medical history differently, so written quotes against an identical specification — same sum assured, same term, same premium type — are the only honest comparison. Pay-out statistics matter when weighing price against reliability: ABI and GRiD data shows protection insurers paid a record £7.34 billion in 2023, equivalent to roughly £20.1 million a day. [10]

Checking the decrease rate against the mortgage

Assumptions: the reader is comparing cover structures and costs only. No premium or pay-out figure is assumed where it has not been published, sourced and dated; the placeholders stand in for the reader’s own documents.

The result is a documented comparison, not a fabricated quote. Where an insurer has not supplied a current written figure, the honest entry remains a visible placeholder until the reader replaces it with their own dated document.

If something goes wrong

If a claim is declined or delayed, complain to the insurer first, in writing, and ask which clause of the policy wording the decision rests on. The insurer must investigate and give a final response. If you are still unhappy after that response — or after eight weeks — the Financial Ombudsman Service can decide the dispute free of charge for consumers, and its protection-insurance casework regularly examines exactly these questions. [5] If the insurer itself fails financially, the Financial Services Compensation Scheme may protect eligible policyholders. For the wider regulatory picture, read who regulates insurance in the UK.

  1. Read the IPID before you buy The Insurance Product Information Document summarises what is and is not covered; the full wording governs.
  2. Answer application questions with reasonable care Ask for clarification in writing if a question is ambiguous; keep a copy of your answers.
  3. Consider writing the policy in trust A trust can keep the pay-out outside your estate and speed up payment to your beneficiaries.
  4. Tell your beneficiaries the policy exists Unclaimed policies are common; keep the documents where the people who need them can find them.
  5. Review cover after life events Marriage, children, a new mortgage or a paid-off one all change how much cover makes sense.
  6. Keep every document Dates, reference numbers and written decisions are what resolve disputes later.

“On the difference between level and decreasing term cover, I would separate the mechanical question from the emotional one. The mechanical question is always: what does this contract pay, to whom, on what evidence, confirmed where in writing? The emotional question — how much your family would need — deserves honest arithmetic, not a round number. When clients keep those two apart, and keep every insurer answer in writing, the surprises almost disappear.”

Trusts, tax and the estate

A life insurance pay-out is generally free of income tax and capital gains tax, but if it lands in your estate it can count towards the value assessed for inheritance tax, which is charged at 40 per cent above the available threshold — the standard nil-rate band is £325,000. [8] Writing the policy in trust — usually free, using the insurer’s standard form — keeps the pay-out outside the estate and lets trustees claim without waiting for probate. HMRC’s own Inheritance Tax Manual confirms a life policy can be placed in trust, and its estate form IHT410 treats policies payable to trust beneficiaries as separate from the taxable estate. [12][13] Our guide to life insurance in trust covers the mechanics in full. Tax treatment depends on individual circumstances and can change, so confirm the current rules on gov.uk before acting.

Common questions

Do life insurance policies actually pay out?
The large majority of protection claims are paid: ABI and GRiD data for 2023 shows a record £7.34 billion paid across group and individual protection policies, with individual life insurance, income protection and critical illness claims accounting for £4.85 billion across 275,000 claims. [10] The precise claims-acceptance rate is not currently verifiable from a primary page, so we do not quote one [STATISTIC REQUIRED: current ABI protection claims-acceptance rate]. The claims that fail usually trace to a small set of causes: the policy had lapsed, the death fell outside the cover terms, or the application had been answered inaccurately — the Ombudsman’s published decisions show insurers relying on exactly those grounds. [9][11] If a claim is declined and you believe the decision is wrong, the Financial Ombudsman Service can decide the dispute free of charge after the insurer’s formal complaints process. [5]
Is a life insurance pay-out taxed?
The pay-out itself is generally free of income tax and capital gains tax. The tax question is inheritance tax: if the policy pays into your estate, the money can count towards the estate value when inheritance tax is assessed — charged at 40 per cent above the nil-rate thresholds. [8] Writing the policy in trust keeps the pay-out outside the estate in most cases, which is why it is so widely recommended. Tax rules depend on individual circumstances and change over time, so confirm the current position on gov.uk or with a qualified tax adviser before acting on it.
What happens if I stop paying the premiums?
On term assurance, stopping premiums ends the cover: the policy lapses, no pay-out is due and there is no cash-in value — term cover has no savings element. Missing payments usually triggers a short grace period and reminder letters before lapse, but the wording governs. [3] On whole of life policies the position depends on the contract: some acquire a small surrender value after many years, others return nothing. If premiums have become unaffordable, ask the insurer in writing what reducing the sum assured or the term would cost before cancelling — a smaller policy usually beats none.
Do I need a medical examination to get life insurance?
Usually not. Standard applications ask health, lifestyle and family-history questions, and for many applicants the insurer decides on the answers alone. For larger sums assured, older ages or disclosed history, the insurer may request a GP report, a nurse screening or an examination — paid for by the insurer. Guaranteed-acceptance over-50s plans ask no health questions at all, in exchange for capped pay-outs and a qualifying period. Whatever the format, the Consumer Insurance (Disclosure and Representations) Act 2012 requires you to take reasonable care to answer accurately — a careless answer can surface at claim years later. [6]
Can I have more than one life insurance policy?
Yes. Life insurance policies are contracts, not licences, and holding several is common — for example a decreasing term policy matched to a mortgage plus a level term policy for family income. Each insurer underwrites its own application, so your disclosure duty applies to every policy separately, and each asks whether related cover exists. The practical checks are affordability across all premiums, and that the combined cover still matches the need rather than duplicating it. If your circumstances change, review the portfolio as a whole rather than policy by policy; our guide to working out how much cover you need walks through the arithmetic.
Is there a cooling-off period after I buy?
Yes. FCA conduct rules give you a statutory cancellation period after a life insurance contract begins — the ICOBS cancellation rules are published in the FCA Handbook [SOURCE REQUIRED: ICOBS 7 cancellation period, current rule text]. If you cancel within the window the insurer must refund premiums, minus nothing more than the rules permit for cover already provided. [3] Cancellation after the window simply ends a term policy with nothing returned. The cancellation right, and how to exercise it, must be set out in the pre-contract documents the insurer gives you before you buy, alongside the Insurance Product Information Document and the full wording.
Where can I get help deciding about the difference between level and decreasing term cover?
The Health Guide provides information only — we explain how products work, what they cost and what your rights are, but we do not give advice and we do not arrange insurance. MoneyHelper, the government-backed money guidance service, publishes free, impartial explainers on life cover types and how to choose between them. If you want a personal recommendation, that is regulated financial advice: check any adviser or broker is authorised on the Financial Services Register before dealing with them. [2] Whoever you speak to, ask for their reasoning and any illustration in writing, and keep it with your policy documents. The FCA’s Consumer Duty requires the firms behind these products to act to deliver good outcomes for retail customers. [4]
