⚡ Editor's Verdict — Essential for Mortgage Holders
Critical illness cover pays a tax-free lump sum if you are diagnosed with a serious illness — cancer, heart attack, stroke. It is separate from life insurance and worth having if you have a mortgage or dependents. Aviva and Legal & General lead on number of conditions covered. |
Critical illness cover (CIC) pays a tax-free lump sum if you are diagnosed with one of the serious illnesses listed in your policy — typically cancer, heart attack, stroke, and many more. The money can be used to pay off your mortgage, cover medical costs, or replace lost income. It is not the same as life insurance. What Does Critical Illness Cover Pay Out For?The number of conditions covered varies significantly by insurer — from around 50 to over 100. Core conditions covered by virtually all UK providers include: - Cancer (most types)
- Heart attack
- Stroke
- Multiple sclerosis
- Organ failure requiring transplant
- Coronary artery bypass surgery
- Total permanent disability
- Blindness
- Deafness
- Loss of limbs
| ⚠️ Always read the full policy definition for each condition — the devil is in the detail. For example, early-stage or less severe cancers may be excluded or pay only a partial benefit. Compare policy wordings, not just the number of conditions. |

What is critical illness cover?Critical illness cover pays a tax-free lump sum if you are diagnosed with a serious illness listed in your policy, such as cancer, heart attack, or stroke. You must survive the diagnosis (usually by 14–30 days) to claim. The money can be used for anything — mortgage payments, medical costs, or living expenses. Is critical illness cover worth it in the UK?For most people with a mortgage or dependents, yes. 1 in 2 people in the UK will develop cancer at some point in their lifetime. Without CIC, a serious illness diagnosis could mean losing your home. The payout can clear your mortgage and give you financial breathing room while you recover. Can I get critical illness cover with a pre-existing condition?It depends on the condition. Many insurers will cover you but exclude the pre-existing condition. A specialist broker can find the best policy for your circumstances. Some conditions may be covered with a loading (higher premium). How much critical illness cover do I need?At minimum, enough to clear your outstanding mortgage balance. Many advisers recommend adding 1–2 years of salary on top to cover living costs while you recover. If you have children, consider adding funds for childcare costs during your recovery period.
