What is Life Insurance and Do You Need It?

Life insurance is one of the simplest but most important financial products available. In exchange for a monthly premium, your insurer agrees to pay a lump sum to your family if you die during the policy term. For most households, it is the foundation of a sensible financial plan — the thing that stops a death from also becoming a financial catastrophe for the people left behind.

This guide explains what life insurance is, the main types of cover available, how premiums and payouts work, who genuinely needs it, and how to go about getting the right policy.

How life insurance works

A life insurance policy is a contract between you and an insurer. You pay a regular premium — usually monthly — and in return the insurer promises to pay an agreed sum (the "sum assured") to your beneficiaries if you die while the policy is in force.

Most policies in the UK are term assurance, meaning they run for a fixed period — say 25 years to match a mortgage. If you die during that term, the policy pays out. If you outlive the term, it simply ends and no payout is made. This is why term life insurance is comparatively inexpensive: in most cases the insurer never has to pay a claim.

The amount you pay is fixed at outset based on your age, health, lifestyle, the level of cover, and the length of the term. Once the policy starts, a guaranteed premium will not change even if your health later declines.

Types of life insurance

There are three main types of cover, and the right one depends on what you are trying to protect.

Level term insurance pays the same fixed amount throughout the policy. If you have £300,000 of level cover, your family receives £300,000 whether you die in year one or year twenty. It is well suited to replacing lost income or covering an interest-only mortgage where the debt does not reduce over time.

Decreasing term insurance pays out a sum that reduces over the term, typically in line with a repayment mortgage balance. Because the insurer's liability falls each year, decreasing cover is usually the cheapest option. It is designed primarily to clear a mortgage, so that your family keeps the home if you die.

Whole of life insurance has no expiry date — it pays out whenever you die, provided premiums are maintained. Because a claim is effectively certain, premiums are significantly higher. It is most often used for estate and inheritance tax planning, or to guarantee a fixed sum is available for funeral costs and final expenses.

Working out which type — and how much — you need is a calculation worth doing properly. Our guide to how much life insurance you need walks through a step-by-step method.

How premiums are calculated

Insurers price each policy according to the risk they are taking on. The main factors are:

• Age. The younger you are, the lower the premium. This is the single biggest reason not to delay.
• Health and medical history. Conditions such as high blood pressure, diabetes, or a history of serious illness can increase the premium or, occasionally, lead to certain causes being excluded.
• Smoking and lifestyle. Smokers typically pay considerably more. Some hazardous occupations or pastimes also affect the price.
• The amount and length of cover. More cover, or a longer term, means a higher premium.

Because pricing is so individual, the only way to know what you would pay is to get a quote based on your own circumstances.

Who needs life insurance?

If anyone depends on your income — a partner, children, or elderly parents — life insurance is worth considering. The main scenarios where it makes sense:

• You have a mortgage. A life insurance payout can clear the debt so your family keeps the home.
• You have children. Replacing your income ensures they maintain their standard of living and have financial security through to adulthood.
• You are self-employed. You will not have an employer death in service benefit to fall back on, so personal cover is often the only protection in place.
• You are a stay-at-home parent. Even without a salary, the cost of replacing childcare and household work can be substantial.

Equally, if you are single with no dependants and no debts that would pass to others, the case for life insurance is much weaker — and being honest about that is part of getting protection right.

How much cover do you need?

A common starting point is around 10 times your annual salary, plus enough to clear your outstanding mortgage. But this is only a rule of thumb. A more reliable approach adds together your mortgage, other debts, an income-replacement figure for your dependants, and an allowance for funeral costs, then subtracts any existing cover such as savings or an employer benefit.

If you rely on an employer scheme, be cautious — it disappears when you change jobs. We explain why in our guide on whether employer death in service cover is enough. A qualified adviser can help you calculate a precise figure based on your actual outgoings and dependants.

Writing your policy in trust

One of the most overlooked aspects of life insurance is writing the policy "in trust". A trust is a simple legal arrangement that directs the payout to your chosen beneficiaries rather than into your estate.

There are two practical benefits. First, the payout usually falls outside your estate for inheritance tax purposes, which can save your family a significant sum. Second, the money can be paid out quickly without waiting for probate, which can otherwise take months. Most insurers offer trust forms free of charge, and an adviser can help you complete one correctly.

Common misconceptions

"It is too expensive." Many people dramatically overestimate the cost. A healthy non-smoker in their 30s can often get substantial cover for the price of a couple of takeaway coffees a week.

"My employer cover is enough." Death in service benefit is valuable, but it is typically only two to four times salary and ends the moment you leave the job.

"I am too young to need it." Cover is cheapest when you are young and healthy, and locking in a low premium early is usually the most cost-effective approach over a lifetime.

"The payout will be taxed." Life insurance payouts are generally free of income and capital gains tax. Writing the policy in trust also helps keep it outside your estate for inheritance tax.

How to get cover

Getting the right life insurance is straightforward when you work with a regulated adviser. They compare policies from across the market, explain the small print, help you decide between level and decreasing cover, and arrange a trust where appropriate — usually free of charge.
