Your complete guide to understanding how critical illness insurance works and why it matters for UK homeowners and families.
What Does Critical Illness Cover Mean?
Critical illness cover (or critical illness insurance) is a policy that pays out a tax-free lump sum if you are diagnosed with one of the serious illnesses listed in your policy — the main illnesses are cancer, heart attack, or stroke.
It’s designed to protect your finances at a time when you are in a period of serious ill health. The payout can help cover your mortgage payments, everyday bills, private treatment costs, or even allow you to take time off work without financial stress knowing you have a lump of cash in the bank.
Think of it as a safety net — so you can focus on getting better, not worrying about money.
How Much Critical Illness Cover Do I Need?
This is one of the most common questions we get at Green & Green Mortgage and protection. The amount of cover you need will depend on your circumstances, but how you determine what amount of cover you will need will be based on:
• Your mortgage balance – Many people choose enough cover to clear their mortgage in full in the event you are diagnosed with a critical illness.
• Your family’s living costs – Think childcare, household bills, groceries, and loan payments.
• Your income – If you’re self-employed or your employer offers limited sick pay, more cover may be sensible. A sum of 2x your annual income would be sufficient to provide you with 2 years (or longer with cutbacks) worth of living expenses.
When Does Critical Illness Cover Start?
Your cover starts as soon as the policy begins and you’ve paid your first premium.
You’ll need to complete a medical questionnaire during the application, and insurers may ask for GP reports depending on your health history. If you have multiple medical disclosures or a complex medical history insurer may ask to see your medical records to make a final decision.
Once active, you can claim if you’re diagnosed with one of the listed critical illnesses in your policy documents — each insurer’s list and definitions vary slightly, which is why advice from an independent broker is key.
What Does Critical Illness Cover Pay Out For?
Critical illness insurance pays out a lump sum if you’re diagnosed with a covered illness that meets the insurer’s definition. The common conditions include in policies:
• Cancer (of specified severity)
• Heart attack
• Stroke
• Multiple sclerosis
• Organ failure
• Major surgery
• Alzheimer’s disease or dementia
Some policies also include children’s critical illness cover at no extra cost, paying a smaller lump sum if your child becomes seriously ill, typically up to £25,000 per child up to age 23.
Which Critical Illness Cover Is Best?
There’s no one-size-fits-all answer — the best critical illness cover depends on:
• The number of conditions covered (some cover 40+, others 70+)
• Whether it includes children’s cover
• The claims record and reputation of the insurer
• The definitions of illnesses (some are broader and easier to claim on)
• Any additional benefits, such as access to virtual GPs, mental health support, or second medical opinions.
As independent advisers, we compare multiple UK insurers from the wider market to find the best critical illness cover for your situation and budget.
Why Is Critical Illness Cover expensive?
Critical illness covers costs more than life insurance because it’s more likely to pay out — you’re statistically more likely to suffer a serious illness during your working life than to die before retirement.
However, the cost varies by:
• Age
• Health history
• Smoking status
• Level and length of cover
Tip: You can often combine life insurance and critical illness cover into a single policy — offering protection for both scenarios and reducing overall costs.
How Much Critical Illness Cover Should I Get?
You don’t need to over-insure yourself. The right amount is enough to:
• Clear your mortgage or debts
• Replace your income for a few years
• Give your family financial breathing space
