Life Insurance vs Critical Illness Cover: What’s the Difference?
🛡️ Most of us have heard of life insurance. Fewer people know what critical illness cover does, and income protection often gets forgotten altogether. They all sit under the “protection” umbrella, but they do very different jobs. This guide breaks down what each one is, when it pays out, and how to work out what might suit you.
Life insurance: protection if you die 🕊️
Life insurance pays out a lump sum if you die during the policy term. Many policies also pay out if you’re diagnosed with a terminal illness, but this varies, so check your wording.
The two most common types are:
Level term: the amount of cover stays the same throughout.
Decreasing term: the amount of cover reduces over time, often in line with a repayment mortgage.
It’s often used to help your family clear the mortgage and cover everyday costs if the worst happens.
Critical illness cover: protection if you’re diagnosed 🩺
Critical illness cover can pay out a lump sum if you’re diagnosed with a serious condition that’s listed in your policy, such as certain types of cancer, a heart attack or a stroke. You get the money while you’re alive, so you could use it for the mortgage, bills, time off work, or changes to your home.
A few things worth knowing:
It only covers the conditions named in the policy, and each one has a specific definition you need to meet.
Policies often have a short survival period after diagnosis before a claim is paid.
It can be added to a life insurance policy or bought on its own.
Income protection: protection for your monthly income đź’·
Income protection pays a regular monthly amount if you can’t work because of illness or injury. You choose how long you wait before payments start (for example, once any sick pay from work runs out).
Payments are usually a percentage of your income rather than the whole amount, and they continue for as long as your policy allows.
Because it’s based on being unable to work, rather than a named diagnosis, it can respond to a wider range of situations than critical illness cover. It can be especially relevant if you’re self employed or if your sick pay is limited.
So which one do you need?
There’s no one size fits all answer. It depends on your circumstances, so it helps to ask yourself:
What would happen to the mortgage and bills if I couldn’t work? Statutory sick pay is a modest fixed weekly amount, and it doesn’t apply to everyone, including the self employed.
Do I already have cover through work? Some employers offer death in service benefit or enhanced sick pay. It’s worth checking what it is, and what happens if you change jobs.
Who depends on my income? Partners, children and other family members.
Do I have buy to let mortgages? Mortgage payments on rental properties continue even if you can’t work, so it’s worth thinking about how they’d be met.
Three common misunderstandings:
“I’ve got life insurance, so I’m covered.” Standard life insurance pays out on death, not when you’re seriously ill.
“Critical illness cover pays out for any serious illness.” It only pays for the specific conditions listed in the policy, and you need to meet the definition.
“Sick pay will see me through.” It depends on your employer or your employment status, and it may not last as long as you’d need.
Key Takeaway
Life insurance, critical illness cover and income protection protect against different things, and the right mix depends on your income, your family and your mortgage. It’s much easier to put the right cover in place while you’re healthy, so it’s worth knowing where you stand before you ever need it.
