Critical illness cover, often shortened to CIC, is one of the most debated protection products in the UK. Some brokers sell it reflexively on every mortgage. Others are sceptical. The truth sits in the middle. CIC is a powerful, expensive, and sometimes slightly mis-sold product. Here’s what you need to know before buying it.
What CIC Actually Pays
Critical illness cover pays a tax-free lump sum if you’re diagnosed with one of a defined list of serious conditions, typically cancer, heart attack, stroke, multiple sclerosis, major organ transplant, kidney failure and a few dozen others depending on the insurer. Payment is made once, and the policy ends. Unlike life insurance, you don’t need to die; unlike income protection, you don’t need to be unable to work. You just need a qualifying diagnosis.
The Catch: Definitions Matter Enormously
Every condition on the list comes with a specific medical definition. Not every heart attack qualifies. Not every cancer qualifies (early-stage prostate and some skin cancers are often excluded). This is why policies from ‘budget’ insurers frequently pay out less than the premium-brand policies; their definitions are narrower. When comparing CIC, the headline premium is not the right number to look at. The number that matters is the quality of the definitions and the number of conditions covered. A good broker cuts through this noise.
Children’s Cover Is a Quiet Standout
Most mainstream CIC policies include children’s critical illness cover at no extra cost (or a small add-on). If your child is diagnosed with a qualifying condition, a lump sum is paid, often £25k–£50k. For a family, this single feature is sometimes the best reason to buy CIC at all. A stay in Manchester Children’s Hospital for a parent who has to drop everything to be there is not a financial impossibility people often plan for.
When CIC Makes Clear Sense
CIC makes particular sense for single-income households, self-employed people whose income stops the moment they can’t work, and parents with young children. Anyone with a significant mortgage and limited savings to ride out a serious illness should at least price it up. The younger and healthier you are when you apply, the cheaper the premium locks in.
When CIC Might Not Be the Priority
If your employer offers a generous ill-health retirement package, or you already have substantial savings and assets, the case for CIC weakens, though it rarely disappears entirely. For very tight budgets, income protection (which pays out on any illness or injury, not just listed ones) is usually the better first-choice product, with CIC layered in later when cash flow allows.
How Much Should You Insure For?
A common approach is to insure enough to clear the mortgage outright, so £250k of cover on a £250k mortgage. Others go smaller, just covering a year or two of lost income, perhaps £60k–£100k. The right answer depends on what you’d actually do if diagnosed. Some families want to pay off the mortgage entirely and reduce stress; others want a lump sum to adapt the house or cover private treatment while keeping the mortgage ticking. Both are valid.
Getting the Policy Right
Buying CIC direct from an insurer means you get their product and their product alone. Through a whole-of-market broker, you compare the likes of Aviva, Vitality, Legal & General, Royal London, Zurich, LV=, AIG and Scottish Widows, and more importantly, the small print underneath each of them. This is not a product to buy on price alone.
