What is term life insurance? A complete UK guide

Term life insurance is a type of life insurance policy that covers you for a fixed period, known as the term. If you die during that term, the policy pays out a cash sum to the people you have named as your beneficiaries. Many UK term policies also include terminal illness cover as standard, which can pay out early if you are diagnosed with a terminal illness during the term. If you are still alive when the term ends, the cover simply stops and there is no pay-out.

This is the defining feature of term cover, and every major UK insurer describes it the same way. You pay a regular premium, and if you die during the term, your family receives an agreed sum of money. Many policies also pay out early if you are diagnosed with a terminal illness during the term.

Term life insurance is a pure protection policy. It has no savings or investment element and only ever pays out on a valid claim, so it has no cash-in value at any time. You cannot cash the policy in or borrow against it. Because you are paying purely for protection, term cover tends to be the most affordable way to buy a large amount of life insurance.

You choose two things when you set up a policy: how much cover you want (the sum assured) and how long you want it to last (the term). Terms commonly run from around 5 years up to 50 years, and some insurers offer terms as long as 70 years.

Everyone's needs and budget are different, so it is impossible to put a single figure on the cost of term life insurance. What you pay is worked out individually when you apply, based on your age, your health and lifestyle, whether you smoke, the amount of cover you want, the length of the term and the type of policy you choose.

As a rough guide to entry-level pricing, several UK insurers advertise cover starting from around £5 to £7 a month. It is worth treating these as lowest-priced illustrations rather than a typical bill: the "from" price generally reflects a young, healthy non-smoker taking a modest amount of cover, and your own premium could be higher.

The single biggest driver of price is your age when you apply. The older you are when you take out a policy, the higher the premiums tend to be, because the insurer is taking on more risk. This is why buying earlier, while you are younger and in good health, usually locks in a lower monthly cost for the life of the policy.

If you are looking into term life insurance, you will find several variations designed to suit different circumstances. In the UK market, a few main types make up the vast majority of policies sold, and it is worth understanding how each one works.

With level term cover, the amount the policy pays out is set at the start and stays the same throughout the term. The cash sum does not change, and your monthly premiums also stay the same for the duration of the policy unless you choose to make a change to it.

Level term is the most common choice for family protection, because the pay-out does not shrink over time. It suits people who want a fixed lump sum available whenever it might be needed during the term, for example to replace lost income, cover an interest-only mortgage or leave a legacy.

With decreasing term cover, the pay-out reduces over the term, while your premiums stay the same throughout, and they are typically lower than for the equivalent level term cover. Because the falling cover carries less risk over time, decreasing term is usually cheaper than the equivalent level term policy.

It is often called "mortgage life insurance" because the reducing pay-out is designed to track the falling balance of a repayment mortgage. There is an important caveat worth knowing. The cover typically reduces roughly in line with a debt at an assumed interest rate of around 7%, so if your mortgage rate is higher than this, the policy may not fully repay your mortgage. It is also designed for a repayment mortgage rather than an interest-only mortgage, where the balance does not fall over time.

Increasing term cover, sometimes called index-linked cover or indexation, is designed to protect the real value of your pay-out against inflation. As the name suggests, it is the opposite of decreasing term: the cover amount is reviewed against measures of inflation so that it rises over time, in return for higher premiums.

The cover amount rises with inflation, so your monthly payments go up too, typically adjusted each year in line with an index such as the Consumer Prices Index or Retail Prices Index. One point to watch is that with indexation, premiums generally increase at a higher rate than the cover amount, so they can climb faster than the benefit over a long term. Increasing term is most useful on longer policies, where the eroding effect of inflation on a fixed sum would otherwise be greatest.

Rather than paying a single lump sum, family income benefit pays a regular income to your family for the remainder of the term if you die. It is a form of decreasing term cover, because the total remaining pay-out falls as the term counts down. It can be a good fit for households who would prefer a steady monthly replacement for lost salary rather than one large payment.

The takeaway is that in the UK, level, decreasing and increasing term, along with family income benefit, are the options you will realistically be choosing between.

Underwriting is how an insurer assesses the risk of insuring you and sets your premium. With most UK term policies the process is straightforward and increasingly done online.

When you apply, you answer a set of health and lifestyle questions and declare your smoker status. For most people that is as far as it goes, and most applicants do not need a medical. If you are applying for a large amount of cover, the insurer might ask you to have a medical with a nurse or a doctor. Larger sums assured, older applicants or disclosed medical conditions are the usual triggers for further evidence, such as a nurse screening or a report from your GP.

Answering these questions fully and accurately matters. Your answers form the basis of the contract, and non-disclosure can affect a future claim.

A few underwriting-related features are worth knowing about:

• Terminal illness cover is frequently included at no extra cost. It can bring the pay-out forward if you are diagnosed with a terminal illness during the term.
• Guaranteed acceptance exists on some products but not on standard term cover. Over 50s life insurance, for instance, typically comes with guaranteed acceptance and no medical questions, but that is a separate whole of life product for older ages, not term insurance.
• Age limits apply at both ends. You generally need to be at least 18 to apply. Maximum entry ages vary by insurer, with some accepting applications up to age 70 and others up to 77. Policies must also finish by a set age, usually somewhere between 80 and 90.
• Writing your policy in trust is offered by most insurers. Placing the policy in trust can speed up payment to your beneficiaries and usually means the claim proceeds will not count as part of your estate for inheritance tax purposes.

The overarching benefit of any life insurance policy is peace of mind. The specific benefits of a term life policy include:

Financial protection for your loved ones. It gives the promise of financial security to the people who depend on you, so they will be provided for if you die during the term. Those who rely on your income could otherwise face real hardship, particularly if they are not yet able to support themselves.

Help repaying debts. If you die leaving unpaid debts, they are likely to be repaid from your estate, which reduces what your beneficiaries receive. If one of those debts is an outstanding mortgage, there is a risk the family home has to be sold. A term life policy can be arranged to cover those debts, leaving your family free of that burden.

Protecting your children's education. If you are funding private schooling or supporting a child through university, the last thing you want is for their education to be disrupted by money. A term life policy can help make sure they continue with the education you intended.

Choosing a life insurance policy is a big decision, and it helps to understand how term cover compares with whole of life cover. The essential difference is simple: term cover lasts for a fixed period and only pays out if you die within it, whereas whole of life cover is designed to cover you for the whole of your life, no matter what age you die, so a valid claim always pays out eventually.

Here is how the two compare across the features that matter most:

• Length of cover — Term life insurance: Fixed term, commonly 5 to 50 years. Whole of life insurance: Lifelong, ends only when you die.
• Guaranteed pay-out — Term life insurance: Only if you die during the term. Whole of life insurance: Yes, as long as premiums are maintained.
• Typical cost — Term life insurance: Lower, protection only. Whole of life insurance: Higher, because a claim is certain.
• Cash-in value — Term life insurance: None. Whole of life insurance: Some policies build a value; guaranteed products may not.
• Main use — Term life insurance: Mortgage, family and income protection for a set period. Whole of life insurance: Lifelong cover, funeral costs, inheritance tax planning.

Because a whole of life policy is certain to pay out at some point, it costs more than term cover, particularly for people with health issues. Term cover, by contrast, keeps costs down precisely because the insurer may never have to pay a claim.

There are several reasons to choose a term life insurance policy, but the main ones are:

Affordability. Term life policies are cheaper than whole of life or other permanent cover, because you are paying purely for protection over a set period with no guaranteed pay-out and no investment element.

Flexibility. You can choose how long your cover lasts and how much cover you want, so your financial commitment is time-limited and can be matched to a specific need, such as the length of a mortgage or the years until your children are financially independent.

No life insurance policy suits everyone, and some features of term cover that are positives for one person can be drawbacks for another:

A fixed expiry date. A term policy does not last forever. That keeps it affordable, but it will not suit you if you are looking for lifelong security, and cover taken out later in life or renewed at an older age can become more expensive.

No cash value. The money you pay into a term policy only funds the pay-out if you die during the term. You cannot access it for any other reason, and if the policy expires with no claim, there is nothing to get back.

Term life insurance is a useful form of financial protection for people in many situations. Common examples include:

Families with dependent children. Looking after a family is a serious responsibility, and the financial safety net of life insurance for parents is valuable for both earners and stay-at-home parents, whose contribution would be costly to replace.

Homeowners with a mortgage. Because a mortgage has to be repaid by an agreed date, the time-limited nature of life insurance for homeowners is a natural match, and it helps ensure your family will not lose their home if you die. Decreasing term in particular is designed around a repayment mortgage.

Young professionals. If you have left education with student loans or other debts, a term policy can help make sure they are not passed on to your family. The younger you are when you take out cover, the cheaper it usually is.

Business owners and partners. If a key person or partner dies, the effect on a business can be significant. Term cover can help fund a replacement, support a restructure, or pay off business loans that would otherwise fall to your estate.

Carers. If you look after elderly parents, or a child with a disability or special needs, a term policy can help make sure they can still be cared for if anything happens to you.

Several established insurers dominate the UK term life insurance market, alongside a new wave of digital-first providers. The right choice depends on the type of cover you need, how you prefer to apply and the extras that matter to you. Here is a quick guide to some of the leading names and what each is known for.

Aviva is one of the UK's largest insurers and offers level, decreasing and increasing (index-linked) term cover. You can apply between the ages of 18 and 77, choose a term from short term up to 50 years, and cover starts from around £5 a month. Most applicants are not asked for a medical, and policies can be written in trust.

Legal & General is another of the biggest UK providers, offering level, decreasing and increasing term cover. It accepts applications up to age 77, supports putting your plan in trust, and provides a Family and Personal Income Plan for households that want a regular income rather than a lump sum. It does not offer renewable or convertible term.

Royal London is a large mutual insurer offering level and decreasing term cover, with terms from 5 to 50 years and entry ages up to 70. Decreasing cover starts from around £7 a month with cover up to £750,000, and Terminal Illness Cover is included at no extra cost.

Vitality combines term life cover with a healthy-living rewards programme. Terms run from 5 to 70 years, cover starts from around £5 a month, and members can save on their premiums by staying active, which sets it apart from more traditional insurers.

Eleos Life is a hybrid digital life insurance provider. It offers a fully online application with a quote in around 15 minutes and most decisions within 24 hours, while also providing support over the phone for people who want to talk through bespoke options. Eleos Life Limited is authorised by the Financial Conduct Authority (FRN 998550), making it a strong fit for anyone who wants a fast, modern digital experience with the reassurance of human help when they need it.

When comparing providers, look beyond the headline monthly price. Consider the type of cover offered, the maximum term and entry age, whether terminal illness cover or trusts are included, the application experience, and the quality of support if you have questions or need to make a claim.

Traditionally, buying life insurance in the UK meant paperwork, phone calls and a wait for a decision. Eleos is changing that by offering term life insurance that is fully digital from quote to cover.

The whole application happens online. Eleos has, in its own words, "streamlined the application so you can spend less time filling out paperwork." You get a quote in around 15 minutes, and the process is built around three simple steps: you answer a set of lifestyle and health questions, you adjust the term length and pay-out amount until you find a monthly premium that fits your budget, and you submit the application. Most applicants receive a decision within 24 hours.

Because everything is designed for the screen, the experience is quick and transparent. You can flex your cover and term to shape a policy around what you can comfortably afford, and a round-the-clock AI assistant is on hand to answer questions about your policy whenever you need it, rather than only during office hours. And because not everyone wants to do everything online, Eleos also offers support over the phone for those who prefer to talk through bespoke options with a person. That hybrid approach, digital by default with human help on hand, is what makes it stand out.

Eleos is a regulated UK insurance provider. According to its own regulatory disclosure, Eleos Life Limited is authorised by the Financial Conduct Authority (firm reference number 998550) and is registered in England and Wales (company number 14010855), details you can confirm on the FCA's Financial Services Register. That combination, a fully digital journey backed by proper regulation, is what positions Eleos as a genuinely modern, digital-first choice for term life insurance in the UK.

You might have thought of term cover as the poor relation of whole of life insurance. After all, why choose something that lasts only a few years when you could have cover for life? Looked at in detail, it is clear there are many advantages to term life insurance, and many people for whom it is the right choice. It is affordable, flexible and well matched to the years when your family, your mortgage and your income need protecting most.

The best decisions are informed ones. Now that you understand how term cover works, the types available in the UK, how underwriting works and how it compares with whole of life, you are in a strong position to choose the cover that fits your life. And with fully digital providers like Eleos, getting protected can take minutes rather than weeks.
