Life insurance provides a financial safety net for the people who depend on you. If you die while the policy is active, the insurer pays a tax-free lump sum to your beneficiaries — helping them cover the mortgage, replace lost income, and maintain their standard of living. This guide explains how UK life insurance works, the different types available, and how to find the right level of cover.
Why You Need Life Insurance
If anyone relies on your income — a partner, children, or other dependants — life insurance is one of the most important financial products you can buy. It can:
- Pay off the mortgage so your family can stay in their home
- Replace your income for the years your dependants would need support
- Cover childcare and education costs that your salary currently funds
- Clear outstanding debts such as personal loans or credit cards
- Fund funeral expenses, which average around £4,000 in the UK
Without cover, your family may face serious financial hardship on top of bereavement. The good news is that life insurance is relatively affordable — a healthy 30-year-old non-smoker can often get £250,000 of cover for under £10 per month.
Types of Life Insurance
Term Life Insurance
Term life insurance covers you for a specific period — typically 10 to 40 years. If you die during the term, the policy pays out. If you survive the term, the policy ends with no payout.
There are three main variants:
- Level term — the payout stays the same throughout the policy (e.g. £300,000 from start to finish). Ideal for income replacement or interest-only mortgages.
- Decreasing term — the payout reduces over time, roughly matching a repayment mortgage balance. Cheaper than level term and perfect for mortgage protection.
- Increasing term — the payout rises each year (usually linked to inflation) to maintain its real value. Premiums are higher but the cover keeps pace with the cost of living.
Whole of Life Insurance
Whole of life insurance covers you for your entire lifetime and is guaranteed to pay out eventually. Premiums are significantly higher than term cover because the insurer knows they will pay a claim. It is commonly used for Inheritance Tax planning — a policy written in trust can provide funds to cover an expected IHT bill.
Critical Illness Cover
Critical illness cover pays a tax-free lump sum if you are diagnosed with a specified serious illness, such as cancer, heart attack, or stroke. It can be purchased as a standalone policy or added to a term life insurance policy. It is more expensive than basic life cover because claims are more common — roughly one in five people claim on critical illness policies.
Income Protection
Although technically a separate product, income protection is worth considering alongside life insurance. It pays a monthly income if you cannot work due to illness or injury, covering you while you are alive rather than only on death.

|---|---|---|---|
| Typical cost | £ (low) | £££ (high) | ££ (medium) |
| When it pays out | On death during term | On death (any time) | On diagnosis of specified illness |
| Payout type | Tax-free lump sum | Tax-free lump sum | Tax-free lump sum |
| Cover period | Fixed (e.g. 25 years) | Lifetime | Fixed (e.g. 25 years) |
| Typical use | Mortgage protection, family cover | IHT planning, funeral costs | Mortgage, living costs during illness |
| Guaranteed payout? | Only if death occurs during term | Yes (eventually) | Only if diagnosed with listed condition |
How Much Cover Do You Need?
Quick Rule of Thumb
Take 10 times your annual gross salary and add any outstanding debts including your mortgage. This gives a reasonable starting figure for most families.
Needs Analysis Approach
For a more tailored figure, add up:
- Outstanding mortgage balance — e.g. £250,000
- Years of income replacement — e.g. 18 years × £35,000 net income = £630,000
- Childcare costs — e.g. £15,000 per year × 10 years = £150,000
- Education costs — e.g. university fees and living costs = £60,000
- Funeral expenses — approximately £4,000–£6,000
Subtract any existing cover (employer death-in-service benefit, savings, partner’s income) to arrive at the gap your policy needs to fill.
Factors That Affect Your Premiums
Insurers price life insurance based on the likelihood and timing of a claim. The main factors include:
- Age — the younger you are, the cheaper the policy
- Health — pre-existing conditions and family medical history can increase premiums
- Smoking status — smokers typically pay double the premium of non-smokers
- Occupation — high-risk jobs (e.g. construction, military) cost more
- Cover amount — higher payouts mean higher premiums
- Term length — longer terms cost more as you are older during the later years
Writing Life Insurance in Trust
Placing your life insurance policy in trust is one of the most important steps you can take. It means the payout:
- Bypasses your estate for Inheritance Tax purposes — potentially saving your family 40% of the payout
- Avoids probate delays — beneficiaries typically receive money within weeks rather than waiting months
- Is directed to your chosen beneficiaries — you decide who benefits, not intestacy rules
Setting up a trust is usually free and straightforward — most insurers provide standard trust forms with the application.
Joint vs Single Policies
A joint life first death policy covers two people and pays out on the first death. It is cheaper than two separate policies but only pays once — the surviving partner is then left without cover and may struggle to get affordable insurance if they are older or in poor health.
Two single policies cost more in total but provide a payout on each death. If one partner dies, the survivor still has their own policy intact. In most cases, single policies offer better value and flexibility for families.
How to Get the Best Deal
- Compare quotes from multiple insurers — prices vary significantly for identical cover
- Use an independent broker — they can search the whole market and may find policies you would not see directly
- Review your cover regularly — as your mortgage shrinks and children become independent, you may need less cover
- Don’t pay for more than you need — decreasing term is much cheaper if you only need mortgage protection
- Be honest on your application — non-disclosure can void your policy entirely
Life Insurance and Mortgages
Most mortgage lenders strongly recommend life insurance and some require it — particularly for interest-only mortgages. A mortgage calculator can help you work out the cover amount needed to match your outstanding balance. For repayment mortgages, a decreasing term policy aligned to your mortgage term is usually the most cost-effective option.
