Income protection insurance pays you a regular income if illness or injury stops you working. This UK guide explains how it works, how it differs from other cover, and what to check before buying.
We insure our cars, homes and phones, but many of us never insure the thing that pays for all of them: our ability to earn. If illness or injury stopped your income tomorrow, how long could you keep up with the bills? For a lot of households the honest answer is "not very long." Income protection insurance exists to answer exactly that question. This guide explains what it is, how it differs from other cover, and what to weigh up before buying. This is general information, not financial advice.
Income protection insurance is a policy that pays you a regular, usually tax-free income if you are unable to work because of illness or injury. Rather than a one-off payout, it replaces a portion of your earnings — typically until you recover, return to work, retire, or the policy term ends.
That regular, ongoing nature is what sets it apart. It is designed to keep money coming in during exactly the period when your salary stops but your outgoings do not. For most working people, their earning power is their single largest financial asset over a lifetime — far bigger than their home — yet it is the one most often left unprotected.
The mechanics are reasonably simple:
Three choices shape both the cover and the cost:
The cheapest policy is not the best if it pays out for only a short time or uses a definition you will struggle to claim under. With income protection, the details quietly decide whether the cover actually works when you need it.
People often confuse the main types of protection insurance. They solve different problems:
| Cover type | What it pays | When |
|---|---|---|
| Income protection | Regular income | While you cannot work due to illness/injury |
| Critical illness cover | One-off lump sum | On diagnosis of a listed serious illness |
| Life insurance | Lump sum (or income) | On death (or terminal diagnosis) |
Critical illness cover pays a single lump sum if you are diagnosed with a specific condition on the insurer's list — useful, but it only covers named illnesses and pays once. Life insurance protects others after you die. Income protection is the one that keeps your household running while you are alive but unable to work, across a far wider range of conditions including stress, musculoskeletal problems and many illnesses that never appear on a critical illness list. Some people hold more than one type; the right mix depends on your circumstances and who relies on you.
It is tempting to assume sick pay would carry you through. In reality, Statutory Sick Pay is modest and time-limited, as GOV.UK sets out, and company sick pay varies enormously — some employers offer months of full pay, many offer little. After that runs out, the income simply stops.
This is where income protection earns its place. Without it, a long illness can force households to drain savings and then turn to borrowing to cover everyday costs — which is the worst possible time to take on debt. Responsible lenders are clear that credit should not be a substitute for resilience; UK lender Credicorp, for instance, sets out in its approach to lending responsibly why affordability and a borrower's wider circumstances matter. Insurance that keeps income flowing means you are far less likely to reach for credit out of necessity in the first place.
Two cheaper foundations should come first, though. A solid emergency fund covers short gaps and the waiting period, and a clear household budget tells you exactly how much income you would actually need to replace. Income protection then handles the longer-term risk that savings alone cannot.
Income protection is a long-term commitment, so it pays to read the detail:
Being honest on the application is essential. Failing to disclose relevant health information can give the insurer grounds to refuse a claim — exactly when you can least afford it.
There is no universal answer. Income protection is most valuable if you have people who depend on your income, limited savings, modest employer sick pay, or you are self-employed with no sick pay at all. If you have substantial savings, a very generous employer scheme, or no dependants and low fixed costs, the case is weaker. Free, impartial guidance from MoneyHelper can help you weigh it up, and a regulated adviser can recommend specific cover suited to your situation.
Income protection insurance safeguards your most valuable asset — your ability to earn — by paying a regular, usually tax-free income if illness or injury stops you working. It is distinct from critical illness cover and life insurance, and the waiting period, payout length and definition of incapacity decide how well it actually protects you. Build an emergency fund and a clear budget first, then consider income protection for the longer-term risk those cannot cover. As ever, weigh it against your own circumstances, and seek impartial guidance or regulated advice before you commit.
