Life and Critical Illness Cover pays out a cash lump sum should you pass away or suffer a serious illness as outlined in the policy’s terms. Life and Critical Illness Cover will pay out in the event of:

  • Death
    Should the worst happen, your policy will pay a claim on the Life Insurance element of the policy paying a tax-free cash lump to your beneficiaries.
  • Terminal Illness
    Most Life Insurance plans include an early payout clause if you are diagnosed with fewer than 12 months to live.
  • Critical Illness Cover
    The Critical Illness element of your policy would pay a claim should you suffer one of the defined critical illnesses, with the main three being heart attack, cancer and stroke.

Where the Life Insurance element pays out on death, the Critical Illness Insurance part pays out in the event of you suffering one of around 40 critical illnesses.

Be aware there are policies which cover fewer than five illnesses and those which cover more than 100, so check the policy terms carefully. The most common claims on Critical Illness Insurance policies are for cancer, heart attacks and strokes.

Do I Need Life and Critical Illness Cover?

Although neither Life or Critical Illness Cover is compulsory, if you have a mortgage and / or a young family it is certainly worth considering.

A Life and Critical Illness Insurance policy can be used to cover eventualities such as a funeral, repay debts, adapt a home to meet a new disability, or financially support the deceased’s family until they can stand on their own two feet.

Setting Up a Life and Critical Illness Policy

There are a vast range of Life Insurance options to consider. Choosing the right type of cover will enable you to secure comprehensive protection at the most cost effective premium.

The Different Types of Life Cover

There are different types of Life Insurance cover that are chosen to cover certain circumstances. It’s important that you choose the right type to meet your needs.

Level Term Life Cover

Level term cover provides you with a fixed sum assured for the entire length of your policy. No matter how long you own your policy for, it will always pay out the sum that was first agreed upon when the time comes to claim.

This type of Life Cover is suitable for protecting an interest-only mortgage or providing financial support to your loved ones after you pass away.

Decreasing Life Cover

Decreasing Life Insurance with Critical Illness Cover will gradually decrease in terms of the sum assured the longer you own the policy, eventually reaching zero and ending.

The cover will decrease at a set rate that you can adjust when you first take out your policy

Decreasing cover is less suitable to protect your family because the payout falls over time. Instead, it is usually used to protect loans and debts that are repaid both in capital and interest terms.

The rate at which your cover decreases is designed to match a repayment mortgage as you pay it off, guaranteeing that your family are able to pay off the rest of the mortgage after your death.

The decrease in cover is what makes it a more cost-effective means of protecting your mortgage loan.

When setting up Decreasing Life Insurance to protect a mortgage, it’s essential you ensure that the policy’s rate of decrease matches the interest rate of your mortgage, or your family could be left with a shortfall.

Increasing Life Cover

Increasing Life and Critical Illness policies – also known as index-linked Life Insurance – are intended to keep up with the rate of inflation, ensuring that the value of your policy doesn’t go down in real (i.e. inflation-adjusted) terms over time.

Your cover will increase at a steady rate throughout the duration of your policy, ensuring that your payout doesn’t depreciate.

One thing to take note of about these types of policies, however, is that your premiums will increase at the same time as your cover.

Some insurers will give you the option to forgo an increase on an annual basis if you are unable to afford the new premiums or feel as you though you don’t need it.

Family Income Benefit

If you intend your Life Insurance payout to support your family’s finances, you might consider taking out a Family Income Benefit policy.

This type of Life Insurance policy will pay out differently to a standard policy, providing your family with monthly benefits to supplement their regular income rather than paying out a lump sum.

For some families, monthly benefits are easier to manage. In addition, a Family Income Benefit policy will continue to pay out until your children are out of education at age 18 or at age 21+ if they choose to attend university.

Do I Need to Write My Policy Into Trust?

With a standard Life and Critical Illness policy that is not written into trust, the lump sum that is paid out goes directly to the policyholder or goes to their estate. If the payout is triggered on death, this lump sum could therefore have inheritance tax levied at 40% on it.

Alternatively, you can write your policy to trust which would result in a claim on the policy being paid into a trust before being distributed to the nominated beneficiaries.

When setting up a trust there is often the option to split out death payments and critical illness payments so you would receive any critical illness payment directly. This is often known as a flexible split trust or a discretionary split trust.

The benefit of this is that the payout would not be affected by inheritance tax or delayed by the probate process, which means your loved ones get the full payout and receive it sooner than they would otherwise.

The Cost of Adding Critical Illness Cover to Life Insurance

Life Insurance with Critical Illness Cover will have a different cost for everyone. There are a range of factors that will influence the cost of your policy – to find out more, try out our Life and Critical Illness Cover Calculator.

Level of Cover

The most obvious factor in the cost of your policy is the level of cover you choose, with bigger payouts leading to more expensive premiums.

While it may be tempting to aim high when it comes to choosing appropriate cover, this can lead to premiums that are difficult to manage and a payout that is bigger than necessary.

The best course of action to avoid this mistake is to align your cover with either the loan you are looking protect or with an estimate of your family’s financial needs after your death.

Length of Cover

The probability of suffering a serious illness or passing away increases the older we get. The longer you need your policy in force the higher the risk the insurer will need to pay out and this is reflected in higher monthly premiums.

Joint or Single Policy?

If you own a joint mortgage or share debt with a partner, you might consider a Joint Life Insurance policy covering both death and critical illness.

This will ensure a payout is received by the surviving partner, or the ill individual, to repay the outstanding loan. It typically pays out on the first instance of death / critical illness, after which the policy ceases.

Waiver of Premium

While some policies will automatically include a waiver of premium, many will offer it as an optional add-on.

Waiver of premium will protect your policy’s premiums if you are unable to work as a result of injury or illness. If you worry that you may be unable to continue paying your premiums if your income stopped for a period of time, it may be a good idea to add it to your policy.

However, considering this cover can cost extra, it’s a decision to consider carefully.

Age

Your age when you apply for your policy will influence what you pay in premiums. This is because, as we age, our health declines and we become more likely to claim on a Life or Critical Illness Insurance policy

The cease age you choose can also have some affect on your policy’s cost and for the same reasons, with a higher cease age adding to your premiums.

Your Health and Lifestyle Habits

Smoking and drinking alcohol excessively can see a hefty sum added on to your premiums. With some types of insurance, smokers can expect to pay nearly double for their policy compared to non-smokers.

In order to benefit from the lower premiums non-smokers receive, you need to be smoke free for a minimum of 12 months before applying for your policy.

Taking part in dangerous activities can also have the same effect. If you have a particularly dangerous occupation or take part in activities and hobbies that may put your health at risk, your policy’s cover and its cost will be affected.

Medical History

The addition of Critical Illness Cover to your policy means your medical history will pay a bigger role in deciding the cost of your policy than it will for straightforward Life Insurance alone.

If you suffer from chronic conditions or have had severe health problems in recent years leading up to your policy application, insurers may either exclude certain conditions under the Critical Illness Cover or increase your premiums to make up for your increased risk of claiming.

As you can see, adding Critical Illness Insurance significantly increases the premiums, especially as we get older, representing the greater risk we present to the insurer.

Critical Illness Cover or Income Protection?

One other option you may want to consider if you’re looking for sickness insurance is Income Protection.

Critical Illness Insurance is designed to pay out for critical conditions as specified by the policy’s terms. While this would be useful if you had a critical illness as defined in the policy, it doesn’t provide cover for other eventualities where you could become injured or ill in a non-critical capacity.

Is Income Protection More Comprehensive?

Two of the biggest causes of work absences, besides coughs and colds etc., are musculoskeletal issues and mental health problems. These are by no means critical but could nonetheless keep you off work for some time.

Income Protection is designed to pay out for anything that medically prevents you from doing your job (subject to any pre-existing medical history), regardless of whether the condition is critical.

It also pays a regular income rather than a lump sum, which can be more useful to support yourself with over time. The most suitable policies are long-term and pay out until retirement, so you potentially could claim until you receive your pension.
