What does critical illness cover include? This guide explains how UK critical illness insurance works, which conditions are covered, and how claims are paid.

Understanding critical illness cover is essential before deciding if it's right for you. Critical illness insurance pays a tax-free lump sum if you're diagnosed with a covered condition. The Association of British Insurers (ABI) has standardised definitions for core conditions, making it easier to understand what's covered across different providers.

Cover is subject to policy terms and conditions. Pre-existing conditions are typically excluded.

Key Points

  • 1Core conditions: cancer, heart attack, stroke
  • 240-60 conditions typically covered
  • 3Cancer = 60-70% of all claims
  • 4Heart attack and stroke = 15-20% of claims
  • 5Tax-free lump sum payment
  • 6ABI model definitions standardise core conditions

Eligibility Criteria

  • Diagnosis must meet policy definition
  • Condition must occur after policy start
  • Survival period applies (usually 14 days)
  • Pre-existing conditions excluded
  • Must be within policy term

Typical Timeframe

Claims are typically paid within 4-8 weeks of diagnosis confirmation. You must survive 14 days after diagnosis for most conditions (survival period).

Next Steps

  1. 1Review full conditions list from insurer
  2. 2Check definitions, not just condition names
  3. 3Compare survival periods between policies
  4. 4Consider add-ons for children's cover
  5. 5Get quotes from multiple providers

Why This Matters for Your Mortgage

Understanding these details helps you make informed decisions during the mortgage process. Every element of your application—from deposits to documentation—affects your approval chances and the rates you can access.

Lenders assess applications holistically, weighing multiple factors together. Knowing what they look for allows you to present the strongest possible application. This is particularly important for non-standard situations where lender criteria varies significantly.

Critical Illness Cover Explained

Critical illness cover pays a tax-free lump sum if you're diagnosed with a serious illness covered by your policy. Unlike income protection which replaces monthly income, critical illness provides a one-off payment that you can use however you choose – whether that's paying off your mortgage, covering medical costs, or taking time off work to recover.

How Much Does Critical Illness Cover Cost?

Premiums vary based on your age, health, smoking status, and the amount of cover. A healthy 35-year-old non-smoker might pay £25-40 per month for £100,000 of cover. Prices increase significantly with age – the same cover for a 50-year-old could cost £80-120 per month.

Critical Illness Protection for Mortgages

Many homeowners take out critical illness cover alongside their mortgage to ensure they can pay off the loan if they become seriously ill. This provides peace of mind that your family won't lose their home during a health crisis. The cover amount typically matches your mortgage balance.
