Disability income insurance: the cover most people overlook
One in four workers will experience a period of disability lasting more than three months before retirement age. Income protection insurance replaces a portion of your earnings during that period — yet it remains one of the least purchased types of personal cover.
What income protection insurance is
Income protection insurance (also called disability income insurance or permanent health insurance in some markets) pays a regular benefit — typically 50–70% of your gross income — if you become unable to work due to illness or injury. Unlike critical illness cover, it is not limited to a list of conditions; it covers any medical reason that prevents you doing your job.
The benefit is paid monthly after a waiting period (the deferred period), and continues until you recover and return to work, the policy term ends, or you reach the selected retirement age — whichever comes first.
The Insurance Information Institute and the ABI both publish data showing that fewer than 10% of UK workers hold standalone income protection cover, despite most households having less than three months of savings.
Key features to compare
Own occupation is the strongest definition — it pays if you cannot do your specific job. Any occupation is much narrower and harder to claim. Always check which applies.
4, 8, 13, 26, or 52 weeks. Match this to when your employer sick pay runs out. A longer deferred period = lower premium.
Typically 50–70% of gross income. Set high enough to cover essential outgoings — mortgage, utilities, food — if your income stopped.
Short-term policies pay for 1–2 years; long-term (permanent health insurance) pays until retirement age. Long-term is significantly more valuable.
Does the benefit increase with inflation? A fixed £2,000/month benefit loses real value over a 20-year claim. Index-linked policies cost more but protect purchasing power.
Stops premiums while you are receiving a benefit — this is usually included automatically. Check with your insurer. See our waiver of premium glossary entry.
Who particularly needs income protection
- Self-employed workers and freelancers — no employer sick pay, no safety net beyond savings. Also see our guide to health insurance for the self-employed.
- Single-income households — where one person's income covers the household's essential costs.
- Those with significant financial commitments — mortgages, dependent care costs, or other fixed obligations that cannot be paused if income stops.
- Workers in physical occupations — where injury risk is higher and an inability to work means an immediate loss of income with no desk-job alternative.
The interaction between income protection and life cover is worth considering as part of a broader financial protection review. Income protection covers living; life insurance covers death. Both may be needed if you have dependants.
Income protection FAQ
Frequently asked questions
- Income protection pays a monthly benefit (typically 50–70% of gross income) for as long as you are unable to work — potentially until retirement age. It covers any illness or injury that prevents you working, not a specific list. Critical illness cover pays a single lump sum on diagnosis of one of a defined list of conditions (usually around 50–60 conditions). The two are complementary rather than interchangeable: critical illness is useful for paying off a mortgage; income protection covers ongoing living costs.
- This is the most important feature to check. Own occupation cover pays a benefit if you cannot perform your specific occupation — a surgeon who loses fine motor control is covered even if they could theoretically do desk work. Any occupation cover only pays if you cannot perform any work at all, which is a far higher bar. Most high-quality income protection policies use own occupation definitions. See our waiver of premium glossary entry for a related concept.
- The deferred period is the time between becoming unable to work and when the policy starts paying. Common options are 4, 8, 13, 26, or 52 weeks. A longer deferred period significantly reduces the premium, because the insurer does not pay short-term absences. If your employer provides full sick pay for three months and statutory sick pay after that, a 13-week deferred period aligns your income protection with your actual income gap. The MoneyHelper guide to income protection explains deferred period options in detail.
- Yes — and it is arguably more important for the self-employed, who have no employer sick pay to fall back on. Self-employed applicants typically use their average pre-tax profit as the basis for calculating the benefit amount. Some insurers require at least one year of self-employment history. Our guide to health insurance for the self-employed covers the broader protection gap for sole traders and freelancers.
