What is critical illness cover? Well critical illness cover pays out a lump sum on a number of conditions*. Now we don't cover them all but we aim to cover the ones that worry us the most. Okay, so think about heart attack, think about strokes and think about cancer.

Who hasn't been impacted by someone who's had cancer? Let me explain the difference between terminal illness cover and critical illness cover because it's often confused. Terminal illness cover is included in all our life insurance policies and what that means is that if you're sadly diagnosed with an illness and the doctor tells you that you've got less than 12 months to live, do you know what we'll do? We'll pay you before you die and what that allows you to do is maybe settle debts, do things for the family, just do anything you want before sadly you die. Now, critical illness cover is designed to a pay out a lump sum on a certain number of illnesses, once you're ill.

So once you're diagnosed, we'll give you the money and then you can choose to do whatever you want to do with it. Life insurance with critical illness cover is an additional extra you can have at outset of the policy but many of our customers find it absolutely essential. So if you think if you die you have a payout and that's absolutely fine but what if you're ill? We all know so many people don't want to be ill.

So how do they cope? When people are ill what do they want to do? Things they want to do maybe a different, maybe they don't want to pay off their mortgage, maybe they want to go on holiday, do things for the family, change their home. That's why so many customers choose to do it and it pays out a lump sum and you know what what's really good? You get to choose how you spend it and who you want to benefit from that. What could be better?

*Critical illness cover could pay out a lump sum if you’re diagnosed with or undergo a medical procedure for one of the specified critical illnesses that we cover during the length of your policy and survive for 14 days from diagnosis.

How much critical illness cover do you need?

The amount of critical illness cover you require depends on various factors that are unique to each individual. For example:

What are your existing financial commitments?

If you have a mortgage, consider how much of your mortgage remains outstanding, and whether you could pay the monthly repayments following a critical illness diagnosis. The same applies if you are renting.

Are your financial circumstances likely to change?

No one has a crystal ball, but you might want to consider whether your current financial landscape will look different in the near future. For example, the arrival of a newborn baby may bring additional financial pressures such as childcare expenditure. It’s worth thinking about your future life plans before deciding how much critical illness cover you might need. However, you can always review your protection needs if things change in the future.

How much would you need to maintain your lifestyle?

Ultimately, Critical Illness Cover could pay out a cash sum for you to use however you choose. For example, it could help with child care costs, household bills or to help maintain your standard of living while you recover.

It’s a good idea to look at your current monthly outgoings and how this could affect you financially. Our life insurance calculator can help you make informed decisions about the protection you need.

Please remember that life insurance is not a savings or investment plan and has no cash value unless a valid claim is made.
