Income Protection Insurance Explained: How It Works and How to Choose a Policy
Income protection insurance pays a regular income if illness or injury stops you from working. This guide explains how the product works, what the key variables are — occupation definition, deferred period, benefit period — and how to choose a policy that fits your financial situation.
How income protection works
Income protection pays a monthly benefit — typically 50–70% of your pre-disability income — for as long as you cannot work, up to the end of the benefit period. Unlike critical illness cover (which pays a single lump sum on diagnosis), income protection provides ongoing income, making it suited to long-term illness or disability. Payments start after the deferred period (the waiting time between incapacity and first payment).
Occupation definition
The most important variable. "Own occupation" pays if you cannot do your specific job — a surgeon with a hand injury cannot perform surgery and would claim. "Any occupation" pays only if you cannot do any work for which you are reasonably suited by education and experience — a much harder test. Own occupation is more expensive but provides significantly better protection for professionals with specialist skills.
Deferred period
The waiting time between incapacity starting and the benefit beginning — typically 4 weeks, 13 weeks, 26 weeks, or 52 weeks. A longer deferred period means a lower premium. The right deferred period depends on your employer sick pay entitlement, savings, and how long you could manage without income. Most self-employed workers with no sick pay choose 4–13 weeks.
Benefit period
How long the policy pays for. Short-term policies (typically 1–2 years) cost less but leave you exposed to longer illness. Long-term policies pay to a fixed age (typically 60 or 65) or for life. For genuine income replacement — particularly for the self-employed — a long-term policy running to retirement is usually the right structure.
Indexation
Some policies increase both the premium and the benefit annually in line with inflation. Without indexation, the real value of the benefit erodes over a long claim. For young policyholders buying cover they may need decades hence, indexed policies are significantly more valuable.
Income protection vs critical illness cover
The two products address different risks and serve different purposes. For a full comparison, see our guide on critical illness vs income protection. In summary: income protection is better for sustained inability to work; critical illness is better for covering a specific diagnosis and the immediate costs it creates (treatment, adaptation, debt clearance).
For the self-employed specifically — where neither product is provided by an employer — our article on income protection for the self-employed covers the specific considerations in more detail. For choosing between these and life insurance, see what insurance do I actually need.
Income protection FAQ
Frequently asked questions
- Insurers typically allow you to cover up to 50–70% of your pre-incapacity earnings. The cap exists because the benefit must not incentivise staying off work — the insurer wants you to have a financial reason to return when able. The payout is usually tax-free (for personally-held policies paid from post-tax income), which means 50–60% of gross income often equates to a close match with net take-home pay.
- Many income protection policies include a "proportionate" or "rehabilitation" benefit — if you return to work in a reduced capacity, the policy pays a partial benefit to make up the income shortfall. Without this feature, a binary "working or not" policy creates a cliff edge that can deter partial return to work. Look for policies that explicitly include proportionate benefit. This is one of the most important features to check when comparing policies.
- Yes — income protection is especially valuable for the self-employed who have no employer sick pay. Self-employed applicants need to provide evidence of earnings (tax returns, accounts) for the insurer to confirm the benefit level. Some insurers have minimum earnings requirements. The deferred period is particularly important for self-employed applicants — it should align with how long you could sustain business operations and personal finances from existing resources. See our article on income protection for the self-employed.
- Most income protection policies cover mental health conditions such as depression, anxiety disorders, and burnout — they are among the most common causes of long-term absence. However, a pre-existing mental health condition may be excluded or subject to a moratorium at underwriting. Be honest and accurate in the health questions: a non-disclosed condition that later causes a claim will likely result in the claim being declined. The coverage of mental health claims has improved significantly in recent years under FCA pressure on insurers to apply consistent standards.
