What Is Life Insurance?
Life insurance pays a tax-free lump sum to the people you choose (your beneficiaries) when you die. You pay a monthly premium to keep the policy active. If you die during the policy term, the insurer pays. If you don't die during the term (for term life policies), the policy simply ends — no refund, no payout.
It sounds simple — and it is, at its core. The complexity comes from choosing the right type, the right amount, and the right term. Get those three things right, and life insurance is one of the most powerful and cost-effective financial tools available.
Life insurance isn't for you — it's for the people who depend on you financially. The question to ask isn't "what happens if I die?" but "what happens to my family financially if I die?" If the honest answer is "they'd struggle seriously," you need life insurance. If the answer is "they'd be fine," you may not.
Who Actually Needs Life Insurance?
You likely need life insurance if:
- You have a mortgage — your co-owner / partner would struggle to pay it alone on their income
- You have children or other dependants who rely on your income
- You're the primary carer — even if you don't earn a salary, replacing your childcare contribution would cost significant money
- You have significant debts (beyond the mortgage) that would fall to others
- Your partner's income alone couldn't maintain your family's lifestyle
You may not need life insurance if:
- You have no dependants and no significant debt
- You have substantial savings/assets that would comfortably support survivors
- Your partner earns enough independently to maintain their lifestyle and pay the mortgage
How Much Life Insurance Do You Need?
Use this framework as a starting point:
| Financial Need | Cover Required | Example |
|---|---|---|
| Mortgage balance | Full outstanding amount | £230,000 |
| Income replacement | Annual salary × years until youngest child is independent | £32,000 × 15 = £480,000 |
| Childcare (if primary carer) | Annual childcare cost × years needed | £15,000 × 10 = £150,000 |
| Other debts | Full outstanding balances | £8,000 |
| Funeral costs | £5,000–£10,000 | £8,000 |
| Total need | ~£876,000 | |
| Less: death in service (employer benefit) | Typically 2–4× salary | -£128,000 |
| Less: savings/investments | Liquid assets available | -£40,000 |
| Insurance needed | ~£708,000 |
This seems large — but term life insurance for younger, healthy non-smokers is surprisingly affordable. A £700,000 level term policy over 25 years for a healthy 35-year-old non-smoker might cost £30–50/month.
Which Type Do You Need?
For most people with a mortgage and dependants: level term life insurance — fixed payout, fixed term, lowest cost for maximum cover. See our detailed Term Life vs Whole Life guide for a full comparison.
For mortgage-only protection: decreasing term — payout reduces in line with your mortgage balance. Cheaper than level term. Doesn't provide income replacement beyond the mortgage.
For income replacement: family income benefit — pays a monthly income to your family for the remainder of the term rather than a lump sum. Often more practical and cheaper than an equivalent lump-sum policy.
Always Write Your Policy in Trust
Writing your life insurance policy in trust is the single most important action most policyholders don't take. Without a trust, the payout forms part of your estate — potentially subject to Inheritance Tax and delayed by probate (which can take 6–18 months). With a trust, the money goes directly to your beneficiaries, typically within weeks, outside your estate.
Writing in trust is free, takes 20 minutes, and is offered by all insurers. Ask for the trust form when you take out the policy. If you already have a policy not in trust, contact your insurer — you can usually add a trust retrospectively.
Check Your Death in Service First
Many employers provide "death in service" benefit — typically 2–4× annual salary paid tax-free to your nominated beneficiary if you die while employed. Check your employer benefits (usually in your contract or HR portal). This can significantly reduce the amount of personal life insurance you need — but remember: you lose it if you change jobs, and it may not be enough on its own for families with large mortgages.
