Critical Illness Cover

Critical illness cover (also called critical illness insurance) pays out a tax-free lump sum if you're diagnosed with a serious illness covered by your policy. It can help you maintain your lifestyle, cover treatment costs, or pay off your mortgage during recovery.

Critical illness cover provides a tax-free cash lump sum if you're diagnosed with a serious illness specified in your policy. You can use the money however you need - from covering living costs during recovery to paying for private treatment or clearing your mortgage.

Unlike income protection (which replaces your salary), critical illness cover gives you a one-off payment when you're diagnosed with a covered condition. This can be particularly valuable for:

  • Replacing lost income - Maintain your family's lifestyle if you can't work
  • Paying off debts - Clear your mortgage, loans, or credit cards
  • Medical treatment - Fund private healthcare or specialist treatment
  • Home adaptations - Make modifications to your property for accessibility
  • Rehabilitation - Pay for physiotherapy, counselling, or recovery support
  • Financial security - Give your family breathing space to focus on your recovery

Critical illness cover can be purchased as a standalone policy or combined with life insurance for comprehensive protection.

Most critical illness policies cover 40-50 serious conditions including the 'Big Three' - cancer, heart attack, and stroke - which account for around 90% of claims.

Standard conditions covered include:

  • Cancer - Excluding less advanced cases, subject to policy terms
  • Heart attack - Of specified severity
  • Stroke - Resulting in permanent symptoms
  • Coronary artery bypass surgery - With surgery to divide the breastbone
  • Multiple sclerosis - With specific symptoms
  • Kidney failure - Requiring permanent dialysis or transplant
  • Major organ transplant - Heart, lung, liver, kidney, pancreas, bone marrow
  • Parkinson's disease - Resulting in permanent symptoms
  • Alzheimer's disease - Before age 60
  • Motor neurone disease - Resulting in permanent symptoms
  • Paralysis - Permanent and irreversible
  • Blindness - Permanent and irreversible
  • Deafness - Permanent and irreversible
  • Loss of limbs - Permanent physical severance
  • Coma - Resulting in permanent neurological deficit

Many policies also include 'additional payment conditions' for early-stage or less severe diagnoses, typically paying 10-25% of your cover amount for conditions like:

  • Less advanced cancers (carcinoma in situ)
  • Early-stage prostate cancer
  • Angioplasty (heart surgery)
  • Low-severity heart attack
  • Low-severity stroke

It's important to read policy definitions carefully, as conditions must meet specific severity criteria to qualify for a full payout.

Critical illness cover costs vary based on your age, health, lifestyle, occupation, cover amount, and policy term. Expect to pay roughly double the cost of life insurance alone when adding critical illness cover.

Factors affecting your premiums:

  • Age - Younger applicants pay significantly less
  • Health history - Pre-existing conditions may increase premiums or be excluded
  • Family medical history - Genetic conditions like cancer or heart disease in close relatives
  • Smoking status - Smokers pay considerably more (typically 50-100% extra)
  • Occupation - High-risk jobs may face higher premiums
  • Cover amount - Higher payout = higher premiums
  • Policy term - Longer terms increase total cost
  • Policy type - Decreasing term is cheaper than level term

Example premiums for £150,000 critical illness cover over 25 years:

  • 30-year-old non-smoker: From £35-50/month
  • 40-year-old non-smoker: From £60-85/month
  • 50-year-old non-smoker: From £130-180/month
  • 30-year-old smoker: From £65-90/month

You can choose from several types of critical illness cover depending on your needs:

Standalone Critical Illness Cover

Pure critical illness protection with no life insurance element. Pays out only if you're diagnosed with a covered condition during the policy term. Most cost-effective if you already have life insurance separately.

Life Insurance with Critical Illness Cover

Combined policy providing both life insurance and critical illness protection. Pays out on diagnosis of a covered condition OR on death (whichever happens first). Most popular option for comprehensive family protection.

Life Insurance with Additional Critical Illness Cover

Separate pots for life insurance and critical illness - can pay out on both. More expensive but provides dual protection, paying for critical illness and still leaving life cover in place.

Children's Critical Illness Cover

Optional add-on covering your children for serious illnesses. Typically pays £25,000-£50,000 if your child is diagnosed with a covered condition. Small additional premium for valuable protection.

You can also choose between:

  • Level cover - Fixed payout amount throughout the term
  • Decreasing cover - Payout reduces over time (usually to match a repayment mortgage)
  • Increasing cover - Payout increases annually to keep pace with inflation

Critical illness cover is worth considering if you have financial commitments like a mortgage or dependents who rely on your income, and you wouldn't have sufficient savings to maintain your lifestyle if you became seriously ill.

Critical illness cover is particularly valuable if:

  • You have a mortgage or significant debts that would be difficult to maintain if you couldn't work
  • You're self-employed with no sick pay or employer benefits
  • Your family relies on your income for daily living expenses
  • You have dependents (children, spouse, elderly parents) who need financial support
  • You don't have substantial savings to cover 6-12 months of expenses
  • You have a family history of serious illnesses like cancer or heart disease
  • You want to afford private healthcare or specialist treatment if needed

You might not need critical illness cover if:

  • You have very generous employer sick pay (e.g., full salary for 12+ months)
  • You have substantial savings or investments to support you during illness
  • You have no dependents or financial commitments
  • You're approaching retirement with a pension already secured

Remember: 1 in 8 men and 1 in 10 women will suffer a critical illness before retirement age. Critical illness cover provides financial peace of mind when you need it most.

Frequently Asked Questions

What's the difference between critical illness cover and income protection?

Critical illness cover pays a one-off lump sum when you're diagnosed with a covered condition, while income protection replaces a percentage of your salary every month if you can't work due to any illness or injury. Critical illness is for specific serious conditions; income protection covers any health issue preventing you from working. Many people have both for comprehensive protection.

Can I get critical illness cover with pre-existing conditions?

Yes, but it depends on the condition and its severity. Minor conditions may have no impact, while serious conditions may be excluded from cover or result in higher premiums. Some conditions may make cover unavailable. Our specialist advisors can help you find insurers who are more accepting of specific medical histories.

Does critical illness cover pay out for mental health conditions?

Standard critical illness policies don't usually cover mental health conditions like depression or anxiety. However, some policies may cover severe conditions like permanent neurological impairment or total permanent disability resulting from mental illness. Mental health support is typically better covered by income protection insurance.

What happens if I don't claim on my critical illness policy?

If you reach the end of your policy term without making a claim, the policy expires and you receive nothing back. Critical illness cover is protection insurance, not an investment - you're paying for peace of mind and financial security. Some policies offer optional premiums back or partial return of premiums for an additional cost.

Can I claim on critical illness cover more than once?

Most policies pay out once and then end. However, some insurers offer 'additional payment cover' or 'multi-claim' options that allow claims for different conditions. After claiming for an additional payment condition (10-25% payout), your main cover usually continues. Always check your policy terms.

How long does a critical illness claim take to pay out?

Most claims are paid within 4-8 weeks once the insurer has all required medical evidence. Some conditions require a survival period (typically 14-28 days after diagnosis) before payment. The claims process involves providing medical reports and evidence that your condition meets the policy definition.
