What is Critical Illness Insurance?
Critical illness insurance provides a tax-free lump sum payment if you are diagnosed with a specific severe illness or condition that is covered by your policy. It is designed to ease financial pressure during a health crisis.
Tax-Free Lump Sum
The payout is made as a single, tax-free payment. You can use this money however you choose, whether to pay off a mortgage, cover daily living expenses, or fund private medical treatments.
Specified Conditions
Policies cover a predefined list of severe conditions. While cancer, heart attacks, and strokes are standard across almost all providers, the exact list of covered illnesses varies by insurer.
Family Protection
Many policies allow you to add children’s critical illness cover at no extra cost, providing a smaller lump sum if your child is diagnosed with a specified childhood illness.
Commonly Covered Conditions
While policies differ, the Financial Conduct Authority (FCA) expects standard definitions for core conditions. Most comprehensive policies will cover at least the following:
Cancer
Coverage typically applies to malignant tumours. Most policies exclude early-stage or non-invasive cancers (like carcinoma in situ), though some premium policies offer partial payouts for these.
Heart Attack
Defined as the death of heart muscle tissue due to inadequate blood supply, evidenced by specific changes in ECG readings and elevated cardiac enzymes.
Stroke
Coverage requires neurological deficits resulting from thrombosis, haemorrhage, or embolism in the brain, with symptoms lasting more than 24 hours and confirmed by imaging.
Major Organ Transplant
Covers the receipt of a human heart, lung, liver, kidney, or pancreas transplant, or a human bone marrow transplant, deemed medically necessary.
Multiple Sclerosis
Diagnosis must be confirmed by a consultant neurologist, with definitive clinical and MRI evidence of demyelination in the central nervous system.
Loss of Independent Existence
Pays out if you become permanently unable to perform a specified number of Activities of Daily Living (ADLs), such as washing, dressing, or feeding yourself.
Key Considerations Checklist
Choosing the right policy requires careful evaluation. Use this checklist to ensure you are making an informed decision.
Review the Full Conditions List
Do not just count the number of conditions covered. Read the specific medical definitions. A policy covering 50 conditions with strict definitions may be less useful than one covering 30 conditions with broader, fairer definitions.
Check for Partial or Early-Stage Payouts
Some modern policies offer a percentage payout (e.g., 25%) for early-stage or less severe conditions, allowing you to claim without terminating the entire policy.
Understand the Exclusions
Pre-existing conditions, self-inflicted injuries, and conditions arising from substance abuse are universally excluded. Ensure you fully disclose your medical history to avoid claim denial.
Survival Period Requirements
Some older policies require you to survive a certain number of days (e.g., 14 or 30 days) after diagnosis to receive the payout. Look for modern policies that have removed this clause.
Indexation and Reviewability
Opt for indexation to ensure your cover amount increases with inflation. Be wary of “reviewable” premiums, which can increase significantly over time; “guaranteed” premiums are generally safer.
Critical Illness FAQ
Everything you need to know about securing and claiming on a critical illness policy in the UK.
Critical illness insurance is a policy that pays out a tax-free lump sum if you are diagnosed with a specific severe illness or condition covered by the policy, such as cancer, heart attack, or stroke. This money can be used to cover mortgage payments, daily living expenses, or medical treatments.
No, it pays a one-off lump sum. If you are looking for regular monthly payments to replace your salary while you cannot work, you should consider Income Protection Insurance instead, or alongside, critical illness cover.
Generally, pre-existing medical conditions are excluded from critical illness policies. Insurers will assess your medical history during the application process and may exclude specific conditions or decline cover based on your health profile.
Once all required medical evidence and documentation are submitted, most insurers aim to process and pay out valid critical illness claims within 2 to 6 weeks. Complex cases or requests for additional medical reports may take longer.
Yes. You can buy them as separate policies, or as a combined policy. A combined policy is often cheaper, but it will only pay out once (either on critical illness diagnosis or death, whichever happens first). Separate policies ensure your family still receives a life insurance payout if you pass away after making a critical illness claim.
