Protection insurance gets sold as a single bundle, but the different types cover genuinely different risks. Buying one because it sounds sensible, without knowing what it actually pays out for, means you can end up covered for the wrong thing, or paying for cover you don't need yet.
The actual question isn't "do I need insurance" — it's which specific risk you're trying to protect against, since that determines which type actually applies.
The main types, actually explained
Life insurance. Pays out a lump sum if you die during the policy term, intended to support dependants, cover a mortgage, or replace lost income for people who rely on you financially. Less relevant if nobody depends on your income.
Income protection. Pays a regular income if you're unable to work due to illness or injury, usually after a waiting period. Covers a different risk from life insurance, being unable to earn, rather than dying, and is arguably more likely to be needed at some point than life cover is.
Critical illness cover. Pays a lump sum on diagnosis of a specified serious illness, defined precisely in the policy: useful for a one-off financial shock like adapting a home or clearing debt, rather than replacing ongoing income the way income protection does.
What actually changes by life stage
No dependants, renting. Life insurance is less relevant here, since nobody relies on your income. Income protection can still matter, since your ability to earn is likely your biggest financial asset regardless of your circumstances.
Mortgage, and/or dependants. This is typically where life insurance becomes more relevant, often sized to cover the mortgage or replace income dependants would otherwise lose; see Mortgages, actually for how lenders size that borrowing.
Later working life, mortgage reducing. Cover needs often reduce as a mortgage shrinks and dependants become financially independent, worth reviewing existing policies rather than assuming the original level of cover still fits.
Where car, van and home insurance fit in
Everything above is protection insurance: cover built around your income and your life. General insurance is a different category entirely, covering damage to or loss of things you own rather than loss of income.
Car and van insurance. A legal requirement to drive on public roads, not optional in the way protection insurance is. Third party covers damage you cause to others; fully comprehensive adds your own vehicle. Price depends heavily on driver history and vehicle, so it's worth shopping around at every renewal rather than letting a policy auto-renew.
Home insurance. Usually two parts, often sold together but not always needed together. Buildings insurance covers the structure itself and is typically a condition of having a mortgage; contents insurance covers what's inside, and matters whether you own or rent.
Both are worth comparing annually: providers don't consistently reward loyalty with a better renewal price, and the cheapest policy at your last renewal is rarely still the cheapest a year later.
Common insurance myths, actually addressed
"Workplace death-in-service benefit means I don't need my own life cover."
It can reduce how much you need, but it's tied to your employer and typically stops if you leave the job: it's worth checking what you'd be left with before assuming it's enough on its own.
"Critical illness cover and income protection are the same thing."
They pay out differently and for different reasons: a lump sum on a specific diagnosis versus ongoing income for inability to work more broadly. Having one doesn't mean you're covered by the other.
"The cheapest policy is the best value."
Price differences often reflect differences in what's actually covered, how illnesses are defined, or how claims have historically been paid, worth comparing what's included, not only the monthly cost.
A simple way to actually decide
- Identify who or what depends on your income: a mortgage, dependants, or neither.
- Check what you already have through a workplace, including any death-in-service or income protection benefit.
- Match the type to the actual risk: death, inability to work, or a specific serious illness, rather than buying broadly.
- Review cover periodically, since needs typically change as a mortgage reduces or dependants become independent.
Insurance worth having as a homeowner with a family
Owning a home and having people who depend on you changes what's actually worth covering. Here's how providers compare across the types that tend to matter most at this stage.
