Income Protection vs Critical Illness Cover: What's the Difference and Which Do You Need?

If you're self-employed, or your household income depends primarily on you, one serious illness or injury could unravel everything you've built. There's no employer sick pay to fall back on. No guaranteed income while you recover. Just a gap where your earnings used to be.

Two insurance products exist specifically to solve this problem: Income Protection and Critical Illness cover. They sound similar, work very differently, and choosing the wrong one, or skipping both, can be a costly mistake.

This guide explains exactly how each works, what they cover, and how to decide which is right for your situation.

Why is it important to have health-related income insurance?

Most people know they should have car insurance and home insurance. Far fewer think seriously about what happens to their finances if they can't work.

The numbers make a sobering case. In late 2025, over 2.8 million people in the UK were off work due to long-term sickness. Almost everyone will face a period of illness or injury during their working life, and for those without cover, the financial consequences can be severe.

State support exists but it's limited. For the self-employed, there's no SSP at all.

Health-related income insurance exists to fill that gap: replacing lost income, covering essential outgoings, and letting you focus on recovering rather than worrying about how the bills will get paid.

There are two main products designed to do this. They work very differently, and understanding that difference is the first step to making the right choice.
