Life insurance is one of the most useful financial products most people barely think about. In plain terms, it’s a contract: you pay a regular premium, and if you die during the policy term, the insurer pays a tax-free lump sum to the people you nominate. That money can clear a mortgage, replace lost income, or simply give your family breathing room at the worst possible time. Here’s what it is, the main types, and how to decide whether you need it.
How life insurance works
You choose a sum assured (the payout amount) and a term (how long you’re covered). The insurer prices your premium based on your age, health, lifestyle and smoking status. If you pass away while the policy is active, your beneficiaries claim the payout. If the term ends and you’re still alive, most term policies simply finish with no payout — that’s why they’re relatively cheap.
The main types of cover
Level term insurance
The payout stays the same for the whole term. Popular for protecting family income or an interest-only mortgage. A healthy 30-year-old non-smoker can often get £100,000 of level term cover for somewhere around £4–£8 a month.
Decreasing term insurance
The payout reduces over time, designed to track a repayment mortgage as the balance falls. Cheaper than level term because the insurer’s liability shrinks.
Whole-of-life insurance
Covers you for life and is guaranteed to pay out eventually, so it’s considerably more expensive. Often used for funeral costs or leaving a guaranteed inheritance.
Add-ons: critical illness & income protection
You can bolt on critical illness cover (a payout if you’re diagnosed with a serious illness) or arrange separate income protection (regular payments if you can’t work). These cover different risks than death — consider them on their own merits.
Do you actually need it?
The honest answer: it depends on who relies on your income. You probably do want life insurance if:
- You have a mortgage or other large debt that wouldn’t be cleared automatically.
- You have children or a partner who depend on your income.
- You’re a business owner with loans, partners, or key-person exposure.
You may not need much if you’re single with no dependants and no debt, or if you have substantial savings and assets that would already cover everything. Check what you already have, too — many employers provide “death in service” cover worth a few times your salary.
How much cover should you get?
A common starting point is enough to clear your mortgage and debts, plus replace your income for the years your family would need it. A rough rule of thumb is 10× your annual income, adjusted for your debts, savings and the ages of any children. The right number is personal — the goal is for your family to maintain their lifestyle, not to over-insure.

- Buy sooner rather than later: premiums rise with age and any new health conditions.
- Be honest on the application: non-disclosure is the most common reason claims are refused.
- Write the policy in trust: this can keep the payout outside your estate and speed it up — ask the provider.
- Compare, don’t default: identical cover can vary noticeably in price between insurers.
The bottom line
Life insurance isn’t about you — it’s about the people who’d struggle financially without you. If that describes someone in your life, term cover is usually inexpensive and worth arranging while you’re young and healthy. If nobody depends on your income, you may be able to skip or minimise it. Either way, the decision is easier once you’ve compared a few real quotes.
