Term Life Insurance UK: Level, Decreasing & Increasing

What is term life insurance?

Term life insurance is the simplest and most affordable form of life cover. It pays out a lump sum to your beneficiaries if you die within a specified term — typically 10, 20, 25, or 30 years. If you survive the term, the policy ends with no payout. Unlike whole of life insurance, there is no investment or savings element; you are paying purely for the death benefit.

Term life insurance is primarily designed to protect people who depend on your income or would face financial hardship if you died. The payout can cover mortgage repayments, living expenses, childcare costs, debts, and funeral expenses. It is the type of life insurance most commonly recommended by financial advisers for families and mortgage holders.

Premiums are fixed for the duration of the policy (assuming you chose a guaranteed premium product) and are based on your age, health, smoking status, occupation, and the amount of cover. A healthy non-smoking 35-year-old might pay £10–£20 per month for £250,000 of cover over 25 years.

Level term vs decreasing term insurance

There are two main types of term life insurance, each suited to different needs:

• Level term: the payout amount stays the same throughout the policy. If you take out £300,000 of cover, your beneficiaries receive £300,000 whether you die in year one or year 24. This is suitable for covering ongoing financial needs like family living expenses or interest-only mortgages
• Decreasing term: the payout reduces over time, roughly in line with a repayment mortgage balance. This is cheaper than level term because the insurer's potential payout decreases each year. It is ideal for covering a repayment mortgage where the outstanding balance falls over time

As a rough comparison, a 35-year-old non-smoker might pay £15 per month for £250,000 of level term cover over 25 years, versus £8 per month for the same initial amount on a decreasing term basis. The decreasing term policy is cheaper because the average amount at risk over the term is much lower.

Many families benefit from having both: decreasing term to cover the mortgage, and level term to provide additional protection for living expenses and childcare costs.

How much cover do you need?

The right amount of cover depends on your personal circumstances, but a common approach is to calculate the total financial obligations your family would face without your income:

• Outstanding mortgage: the full remaining balance if you have a repayment mortgage
• Annual income replacement: multiply your after-tax income by the number of years your family would need support (often 10–20 years)
• Childcare costs: if your partner would need to pay for childcare to continue working, factor in the cost until children are independent
• Outstanding debts: credit cards, car finance, personal loans
• Funeral costs: typically £4,000–£6,000 in the UK

As a simplified rule of thumb, many advisers suggest cover of 10–15 times your annual salary plus your outstanding mortgage. However, a proper needs analysis with a financial adviser will give you a more accurate figure.

What affects the cost of term life insurance?

Several factors determine your premium:

• Age: the younger you are when you take out the policy, the cheaper it is. Premiums increase significantly for each decade of age
• Smoking status: smokers (including vapers and nicotine replacement users with some insurers) pay 50–100% more than non-smokers
• Health: pre-existing conditions, family medical history, BMI, and blood pressure all affect pricing
• Occupation and hobbies: hazardous jobs or high-risk hobbies (such as scuba diving or rock climbing) increase premiums
• Policy term: longer terms cost more because the probability of a claim increases
• Cover amount: higher sums assured mean higher premiums

Writing your policy in trust

One of the most important but often overlooked steps is placing your life insurance policy in trust. This means the payout goes directly to your named beneficiaries without forming part of your estate for probate or inheritance tax purposes.

Without a trust, the payout is added to your estate, potentially pushing it above the IHT threshold and incurring a 40% tax charge. It can also be delayed for months while probate is completed. Writing a policy in trust is usually free and takes just a few minutes — your insurer or adviser will provide the trust form.

Joint life vs single life policies

Couples can choose between two single life policies (one for each partner) or a joint life policy that covers both. A joint policy is typically cheaper but only pays out once — usually on the first death — leaving the surviving partner without cover. Two single policies cost slightly more but provide a payout on each death.

For most couples with children, two separate policies offer better value because the surviving partner retains their own cover. This is particularly important if remarriage or changed health makes obtaining new cover difficult or expensive after a first death payout.
