TL;DR

In short

  1. Life insurance can pay a lump sum or regular benefit after a valid claim while the policy is in force; who receives it depends on the policy ownership, trust or beneficiary arrangements.
  2. Income protection can provide a regular benefit if illness or injury prevents you from working, subject to the policy’s definition, deferred period, benefit limit and other-income rules.
  3. Redundancy is not normally covered by income protection; separate unemployment or accident, sickness and unemployment (ASU) cover may be available and has its own eligibility and exclusions.
  4. Critical illness cover can pay a lump sum for a condition that meets the policy’s definition and severity requirements. It is different from income protection and may complement it.
  5. Compare the household shortfall with existing sick pay, savings, benefits and cover, then check the premium, exclusions, claim limits and policy terms are affordable and suitable.

Life can change unexpectedly. Protection insurance may help some households manage a financial shortfall after death, illness or injury, but it is not a replacement for savings, employer benefits or practical support. The right approach depends on your circumstances, budget and the terms of any policy.

Protect your life

Life insurance can pay a benefit following a valid claim while cover is active. Depending on the policy, this may be a lump sum or a regular payment such as family income benefit. Who receives the money depends on the policy ownership, any trust and beneficiary arrangements. Term life cover lasts for its selected term, while whole-of-life policies have different conditions and premiums. MoneyHelper explains the main types of life insurance.

Decreasing-term life cover is commonly intended for a repayment mortgage. Its contractual cover reduces over time, but it does not automatically follow your actual mortgage balance. The amount, term and assumed interest rate need to suit the mortgage, and a shortfall can still arise. It is generally not a simple match for an interest-only mortgage, where the capital balance does not reduce. It is different from mortgage payment protection for illness or unemployment. It may cost less than equivalent level cover in some cases, but quotations and terms vary.

Consider whether people depend on your income, whether there are debts or essential costs to protect, and what savings, employer benefits or existing cover are already in place. You can also compare types of life insurance in the UK before deciding whether cover is appropriate.

Protect your income

Income protection can provide a regular benefit if illness or injury prevents you from working, subject to the policy’s definition of incapacity or occupation. The benefit is usually a part of eligible earnings and is subject to the insurer’s maximum and rules about other income. For self-employed people, evidence of income and any averaging method can vary by policy. MoneyHelper’s guide to income protection outlines the main features to compare.

Income protection does not normally cover redundancy. Separate unemployment cover or accident, sickness and unemployment (ASU) cover may cover redundancy where available, subject to their own eligibility criteria and exclusions. Mortgage payment protection may cover redundancy only when unemployment cover is included. For example, known or voluntary redundancy and employment status can affect a claim. MoneyHelper explains redundancy insurance.

Benefits can end when you recover, at policy expiry, retirement or death, or when a selected claim limit is reached. Some policies have shorter claim limits, while others can run for longer; the terms are not the same for every policy. Check the agreed deferred period and consider how sick pay and savings would bridge it. Read more about income protection insurance.

It may be useful to compare essential spending and debts with sick pay, savings, other household income and existing cover. Government support can be conditional, so check current eligibility rather than assuming it will or will not meet a shortfall.

Protect yourself in case of illness

Critical illness cover can pay a lump sum for specified conditions, which may include some cancers, heart attacks, strokes or multiple sclerosis. A diagnosis must meet the policy’s exact definition, severity requirements and any applicable survival requirement; not every cancer, heart attack or disability will qualify. A personal-policy lump sum is normally tax-free under current UK rules, but tax treatment can differ for employer-funded or business arrangements. Insurance payments can also affect means-tested benefits depending on the benefit and individual circumstances. MoneyHelper explains critical illness cover.

Critical illness cover is a lump-sum policy, whereas income protection relates to an inability to work. They can complement one another, but neither automatically replaces the other. With combined life and critical illness cover, a full claim may end the policy; partial or additional benefits vary. Our critical illness insurance guide provides further background.

When applying, answer the insurer’s health, occupation and other questions accurately and completely. These answers can affect acceptance, premiums, exclusions and terms, and mistakes can affect a claim. Review the schedule, exclusions, benefit limits and waiting terms, keep premiums paid, and consider whether the cover remains suitable as your circumstances change.

Which policy?

Use a needs checklist rather than assuming that one product suits everyone:

  • Who depends on your income, and which essential spending or debts would continue?
  • What sick pay, savings, employer benefits, household income and existing cover could help?
  • How long would a shortfall last, and what deferred period could you bridge?
  • Is the premium affordable, and do the policy’s exclusions, definitions and benefit limits meet the need you identified?
  • If redundancy is a concern, is separate unemployment cover available and suitable under its terms?

How can I decide?

Start with the financial shortfall you want to address, rather than with a product. For life cover, consider the costs and debts that could remain if you died. For income protection, list essential spending and compare it with the income and support that would continue if you could not work.

Then compare policy terms carefully. Check what is covered, the definitions used, exclusions, deferred periods, claim limits, premiums and any review dates. An adviser can help you understand the options, but a policy should be chosen only when it is affordable and suitable for your circumstances.

Protection insurance cannot guarantee a claim or remove every financial risk. Keep your policy information up to date and review it when your household, work, debts or budget changes.

FAQ

Frequently asked questions

What is the difference between life insurance and family income benefit?

Life insurance may pay a lump sum after a valid claim while the policy is in force. Family income benefit is a form of life cover that can pay regular payments instead. The recipient depends on the policy ownership, trust or beneficiary arrangements.

Does income protection cover redundancy?

Not normally. Income protection generally relates to illness or injury that prevents you from working. Separate unemployment cover or accident, sickness and unemployment (ASU) cover may cover redundancy, subject to their own eligibility criteria and exclusions. Mortgage payment protection may cover redundancy only when unemployment cover is included. Known or voluntary redundancy and employment status can affect a claim.

How does decreasing-term cover work with a mortgage?

Decreasing-term life cover is commonly designed for a repayment mortgage and reduces over its term. It does not automatically track the outstanding balance, so the cover amount, term and assumed interest rate need to fit the mortgage. It is not a simple match for an interest-only balance.

What does critical illness cover pay for?

It can pay a lump sum if a specified condition meets the policy’s definition and severity requirements. The conditions, exclusions, survival requirements and any partial benefits vary, so it is important to read the policy terms.

How do I choose the cover and deferred period?

Compare the financial shortfall with existing sick pay, savings, household income, employer benefits and current cover. Choose only a premium, benefit limit and deferred period that you can afford and that fits the policy terms and your circumstances.
