Whether you need life insurance depends on whether other people rely on your income or the practical contribution you make to the household. If you have dependants, a mortgage, or a partner who could not manage financially without you, life insurance is almost certainly worth having. If you live alone with no debts and no one depending on you, it is far less urgent.
Short Summary
Life insurance pays out a lump sum or regular income to your beneficiaries if you die during the policy term. Its primary purpose is to replace the financial contribution you would have made had you lived.
Parents with young children, mortgage holders, and anyone whose death would leave a partner or family member in financial difficulty should seriously consider life insurance.
The earlier you take out a policy, the cheaper it is. A healthy non-smoker in their 30s can typically get meaningful cover for less than £15 per month, according to figures from comparison sites including MoneySuperMarket.
Life insurance does not have to be expensive or complicated. A straightforward level term policy linked to the length of your mortgage or the period your children need financial support is sufficient for most families.
Who genuinely needs life insurance?
The clearest case for life insurance is when other people depend on your income or contribution. This covers:
Families where one partner is the primary or sole earner. If you died, your partner would need to cover the mortgage, bills, childcare, and daily living costs on their own.
Households where one person is the full-time caregiver. A stay-at-home parent does not receive a wage, but their contribution has a real financial value. Childcare, household management, and school logistics all cost money if someone else has to provide them. The surviving partner would face these costs while also working full time.
Mortgage holders. If you die mid-mortgage and your estate cannot cover the outstanding loan, your family may be forced to sell the home. A decreasing term life insurance policy, which reduces in line with your outstanding balance, is designed specifically for this situation and tends to be cheaper than level term cover.
Who may not need life insurance?
Single people with no dependants and no significant debt generally have less need for life insurance. If no one else relies on your income, there is no financial gap to fill.
People with substantial savings or assets may also find that life insurance is less critical, since existing wealth can provide for dependants without a separate policy. Similarly, if your employer provides a generous death-in-service benefit, this may provide sufficient cover for your family's immediate needs.
What types of life insurance are available?
| Policy type | What it covers | Best suited to |
|---|---|---|
| Level term | Fixed lump sum paid if you die within the term | Families wanting a set amount for dependants |
| Decreasing term | Payout reduces in line with outstanding mortgage | Mortgage repayment protection |
| Whole of life | Pays out whenever you die, no fixed term | Estate planning, funeral costs |
| Family income benefit | Regular income rather than lump sum | Replacing a salary over a period of years |
Most families looking for straightforward protection will find that a level term or decreasing term policy meets their needs.
How much cover do I need?
A commonly used starting point is a multiple of your annual salary, typically between 10 and 15 times your income. However, the right amount depends on your specific circumstances: the size of your mortgage, how many children you have and their ages, your partner's income, and how long your dependants would need support.
A free protection specialist or independent financial adviser can help you calculate a precise figure. The Money Advice Service also has a useful online tool for estimating your cover needs.
How much does life insurance cost?
The cost depends on your age, health, whether you smoke, and the level and term of cover you need. A healthy non-smoker in their early 30s can typically get £200,000 of level term cover over 20 years for between £8 and £15 per month. Smokers pay significantly more. Any pre-existing health conditions will also affect the premium.
Frequently Asked Questions
Do I need life insurance if I have a mortgage?
Most people with a mortgage and dependants should have life insurance. If you died with an outstanding mortgage balance and no protection in place, your family could lose the home. A decreasing term policy, designed to run alongside your mortgage, is typically the most cost-effective option.
Does a stay-at-home parent need life insurance?
Yes. Even without a salary, a stay-at-home parent provides childcare, household management, and practical support that would cost significant money to replace. A life insurance policy on a non-earning parent protects the surviving partner from the financial impact of covering those costs alone.
Can I get life insurance with a pre-existing health condition?
Often yes, but the premium will usually be higher. Some conditions may result in exclusions within the policy. Specialist insurers and brokers can help you find cover even with a complex medical history. The Association of British Insurers recommends disclosing all relevant health information accurately to avoid a future claim being rejected.
What happens if I miss a life insurance payment?
Most insurers offer a short grace period, typically 30 days, during which you can make up a missed payment without the policy lapsing. If you miss payments beyond the grace period, the policy will usually be cancelled and you will lose your cover. Contact your insurer immediately if you are struggling to pay.
Is life insurance the same as critical illness cover?
No. Life insurance pays out only if you die. Critical illness cover pays out if you are diagnosed with one of a specified list of serious illnesses, such as cancer, heart attack, or stroke, while you are still alive. Many people take out both together, as the risks they cover are different.
