Life Insurance vs Critical Illness Cover: Which Do You Need?

If you've got a mortgage and people who depend on your income, two specific kinds of insurance directly protect them: life insurance (pays out on death) and Critical Illness Cover (pays out if you get a specific serious illness but survive). They overlap in purpose but cost very different amounts and trigger on very different events. This guide walks through what each does, when each is the right answer, and how most people end up combining them.

Life insurance in plain English

Life insurance pays a lump sum (or income) to your beneficiaries if you die during the term of the policy. Two common UK forms for mortgage holders:

• Level Term life insurance: the payout stays the same throughout the policy. Good for repayment mortgages (where the balance is shrinking) AND for leaving a lump sum behind. Typically 20-35 year terms.
• Decreasing Term life insurance (Mortgage Protection): the payout reduces in line with a repayment mortgage's outstanding balance. Cheaper than level term because the average payout over the policy is lower. Only useful if the sole purpose is to clear the mortgage.

Critical Illness Cover (CIC) in plain English

CIC pays a lump sum if you're diagnosed with one of a specific list of serious illnesses (heart attack, stroke, cancer, MS, kidney failure, etc.), usually meeting strict severity criteria. You don't have to die for it to pay. You typically have to survive 14-28 days after diagnosis (the 'survival period').

Coverage and definitions vary substantially between insurers, this is one product where the cheap option is often dramatically worse than the slightly more expensive one. The number of illnesses covered, the severity definitions, and the children's cover all vary.

Why people often buy both

Life and CIC do different jobs:

• Life insurance protects your family financially if you die.
• CIC protects you AND your family financially if you survive but can't work / face huge medical or lifestyle costs.
• Many mortgage holders buy both, often combined as a single policy with a single premium, paying out on whichever event happens first.

What CIC costs vs life-only

Rough numbers for a healthy non-smoker, age 35, £200,000 cover, 25-year term:

• Level Term life only: £8-£15 per month.
• Decreasing Term life only (mortgage protection): £6-£10 per month.
• Life + CIC combined: £25-£45 per month.
• CIC alone: often more expensive than life-only because the probability of claim is significantly higher.

Standalone vs combined policies

Combined policies (life + CIC, single payout on first event) are cheaper than buying two separate policies, but the single payout means you've used your protection in one go.

Two standalone policies (one life, one CIC) cost more but give two separate payouts if both events happen. For families with substantial mortgages and dependants, standalone often makes sense; for moderate cover, combined is usually the cleaner answer.

How much cover should you buy?

Rough framework:

• Life insurance, at minimum, enough to clear the mortgage outright. Many people add 3-5 years of household income on top.
• CIC, at minimum, enough to clear the mortgage. Many add a buffer for medical costs, home adaptations, time off work, lifestyle changes.

Important: CIC vs Income Protection, different products

Critical Illness Cover is a lump-sum payout for specific named illnesses. Income Protection pays a monthly income if illness or injury stops you working (any condition meeting the policy's definition, not just specific illnesses).

Income Protection often beats CIC for people whose biggest risk is being unable to work for an extended period due to a less serious illness or injury. CIC beats Income Protection for catastrophic events where you need a large lump sum immediately. Many people benefit from both.

Practical buying tips

Before you sign anything:

• Disclose everything. Health questions matter; non-disclosure invalidates the policy when you need it most.
• Check definitions on CIC. 'Heart attack' or 'cancer' in one policy may differ substantially from another. The cheapest policy often has the narrowest definitions.
• Buy young. Premiums rise sharply with age and any health change. Buying at 30 vs 45 can halve the lifetime cost.
• Write in trust. Life insurance written in trust pays out outside your estate, avoiding probate delays and (for some estates) Inheritance Tax.
• Get advice. Protection isn't a place to economise on broker advice. A specialist protection adviser can save you from buying the wrong product.

Buying life insurance and CIC isn't fun, but neither is a family forced to sell the house after a serious illness. A 30-minute conversation with a specialist now usually saves both money and bad outcomes later.
