Whilst it's possible to arrange critical illness cover without life insurance from certain providers, more commonly the products are sold as a combined policy.
Therefore, to determine how much life insurance and critical illness cover you require, you should consider not only the financial impact of you no longer being able to work, but also your passing.
Therefore, when arranging a combined life insurance and critical illness policy, you should also factor in expenses such as funeral costs and an inheritance (should you wish to leave one).
According to SunLife, the average cost of dying is £9,658 with the average cost of a basic funeral being £4,141[1].
Therefore, a combined life insurance and critical illness policy is likely to require a much higher cover amount (or sum assured).
Arranging combined life insurance and critical illness cover may be cheaper on a monthly basis as it only requires paying one premium, but it will also only result in one pay out.
Therefore, if you're diagnosed with a life-changing illness and make a claim, your life insurance will also expire.
