Critical Illness Insurance

Critical illness insurance is a type of cover that pays out a tax-free lump sum if you are diagnosed with a serious illness listed in the policy, such as cancer, a heart attack or a stroke. The payout can help you cover expenses, clear debts, or adapt your lifestyle while you focus on recovery.

Unlike standard life insurance, which pays out after death, critical illness insurance supports you financially during a life-changing illness, reducing financial stress at a difficult time.

A serious illness can significantly affect your life — not just physically and emotionally, but financially too. The main reasons people take out cover are:

• Financial support during recovery — use the lump sum to cover lost income, mortgage payments, or everyday living costs if you are unable to work.
• Pay for treatment or adaptations — cover private treatment, home modifications, or care services that may not be fully available on the NHS.
• Protect your family’s future — make sure your household stays financially secure through a long recovery.

Around one in two people in the UK will develop cancer during their lifetime, and conditions such as heart attacks and strokes remain common. Critical illness cover puts a safety net in place for the unexpected.

Critical illness cover suits people at a range of life stages:

• Homeowners with mortgages — a payout could help you keep your home through a period of illness.
• Parents and guardians — protect your family’s financial stability if you are unable to work.
• Self-employed people — without sick pay behind you, a lump sum provides security during recovery.
• Anyone without significant savings — a lump sum can be a lifeline for unexpected costs.

It is worth assessing your current financial commitments — loans, dependants and living costs — to decide whether this cover is right for you, and whether income protection might serve you better.

1. Choose your cover

Choose a cover amount and term that fit your needs — often aligned with the outstanding term on your mortgage, or the years until your children are financially independent.

2. Pay your premiums

Premiums are based on factors such as your age, health, lifestyle and the level of cover chosen. Guaranteed premiums stay fixed; reviewable premiums can rise.

3. Make a claim

If you are diagnosed with a qualifying illness, you submit a claim to the insurer with the medical evidence the policy requires. Definitions of each condition are set out in the policy documents.

4. Receive the lump sum

You then use the tax-free payment however you need to as you focus on recovery — there is no restriction on how the money is spent.

Choosing the right critical illness policy is genuinely complex, because two policies at the same price can cover very different lists of conditions. An adviser can help you:

• Understand your needs — assess your personal circumstances, family commitments and financial goals.
• Compare policies — navigate the options from various providers to find comprehensive cover at a competitive price.
• Identify gaps in your protection — make sure life insurance, income protection and critical illness cover work together rather than overlapping.
• Save time and money — cut through the jargon and streamline the process of securing the right cover.
