Two Important Policies, Often Confused
Income protection and critical illness cover are both designed to support you financially when illness or injury strikes — but they work very differently. Understanding the distinction helps you decide which one (or whether both) fits your situation.
What is Income Protection Insurance?
Income protection (IP) insurance pays you a regular income if you're unable to work due to illness or injury. It typically replaces a percentage of your gross salary — commonly 50–70% — and continues paying until you either return to work, retire, or the policy term ends.
Key features of income protection:
- Pays a regular monthly income (not a lump sum)
- Covers a very wide range of conditions — including mental health issues and musculoskeletal problems
- Can pay out multiple times over the life of the policy
- Has a "deferred period" (waiting time before payments begin) — typically 4, 8, 13, 26, or 52 weeks
- Continues until you can work again or the policy ends
What is Critical Illness Cover?
Critical illness cover (CIC) pays a one-off, tax-free lump sum if you're diagnosed with one of the specific conditions listed in your policy. These typically include certain cancers, heart attacks, strokes, and other serious illnesses. Once the lump sum is paid, the policy ends.
Key features of critical illness cover:
- Pays a single, tax-free lump sum
- Only covers conditions explicitly listed in your policy
- Pays out on diagnosis — even if you recover and return to work
- Often combined with life insurance for a cost-effective package
- Does not cover most mental health conditions or common musculoskeletal issues
Side-by-Side Comparison
| Feature | Income Protection | Critical Illness Cover |
|---|---|---|
| Payout Type | Monthly income | One-off lump sum |
| Payout Trigger | Unable to work | Diagnosis of listed condition |
| Conditions Covered | Very broad | Specific listed conditions only |
| Duration of Payout | Ongoing until recovery/retirement | Single payment, then policy ends |
| Mental Health Cover | Usually yes | Rarely |
| Relative Cost | Higher | Lower–Medium |
Real-World Scenarios
Scenario A: Back injury preventing work for 9 months
Income protection wins. Critical illness cover would not pay out for a bad back (not a listed condition). Income protection would replace your salary throughout.
Scenario B: Diagnosed with a heart attack, recover fully in 3 months
Critical illness cover wins. You recover quickly, but you receive the full lump sum regardless. Income protection would only pay during the period you couldn't work.
Do You Need Both?
Ideally, yes — they complement each other well. If budget is limited, consider your biggest risk. The most common reason people can't work long-term in the UK is musculoskeletal conditions and mental health issues — both covered well by income protection. If you have a family history of serious illness, critical illness cover may also be a priority.
A Note on Employer Benefits
Check what your employer provides first. Some employers offer group income protection as a benefit. If yours does, you may need less individual cover. Always understand the terms before assuming you're fully covered.
