Income protection insurance replaces a portion of your income if you’re unable to work due to illness or injury.
How It Works
| Feature | Typical Amount |
|---|---|
| Income replacement | 50-70% of gross income |
| Payment term | Until retirement, or fixed term (1-5 years) |
| Deferred period | 1-12 months (before payments start) |
| Premium | 1-5% of income |
| Tax on payments | Taxable (received as income) |
What It Covers
| Covered | Not Covered |
|---|---|
| Long-term illness | Pre-existing conditions (usually) |
| Accidents | Self-inflicted injuries |
| Mental health conditions | Unapproved activities |
| Back problems | Redundancy (separate insurance) |
| Cancer | Pregnancy (usually first 3 months) |
| Heart conditions | Elective surgery |
Deferred Period
| Deferred Period | Monthly Premium | When Payments Start |
|---|---|---|
| 1 month | Highest | After 1 month off work |
| 3 months | Moderate | After 3 months |
| 6 months | Lower | After 6 months |
| 12 months | Lowest | After 12 months |
Choose a deferred period that matches your savings. If you have 6 months of emergency fund, choose a 6-month deferred period.
Payment Term Options
| Term | Description | Best For |
|---|---|---|
| Short-term (1-2 years) | Low premium, limited cover | Basic protection |
| Long-term (5 years) | Moderate premium, decent cover | Most people |
| To retirement (age 68) | Higher premium, full cover | Comprehensive cover |
Who Needs Income Protection
| Occupation | Risk Level | Need |
|---|---|---|
| Construction worker | High | Essential |
| Self-employed | High | Essential |
| Office worker | Low-Medium | Recommended |
| Public sector | Low (sick pay) | Optional |
| NHS/teacher | Low (generous sick pay) | Less urgent |
Cost Factors
| Factor | Effect on Premium |
|---|---|
| Age | Higher with age |
| Health | Pre-existing = higher or excluded |
| Occupation | Riskier = higher |
| Smoking | Higher |
| Deferred period | Longer = lower |
| Payment term | Longer = higher |
| Amount of cover | More = higher |
Income Protection vs Other Products
| Product | What It Covers | Duration |
|---|---|---|
| Income Protection | Illness or injury stopping work | Long-term |
| Critical Illness Cover | Specific illnesses (one-off payout) | Single lump sum |
| Accident & Sickness | Short-term illness/accident | 12-24 months |
| Life Insurance | Death | Remainder of term |
Bottom Line
Income protection insurance is essential if you don’t have significant savings or generous sick pay. It pays 50-70% of your income if you can’t work due to illness or injury. Choose a deferred period that matches your emergency fund. The longer the deferred period, the lower the premium. Self-employed people should prioritise this cover.
What matters most
The two settings that shape cost and protection are the deferred period and the payment term, so get them right before comparing premiums. The deferred period should reflect real life: if an illness struck, how long could you actually manage without income? Match it to a savings buffer of roughly 3-6 months, which lets you take a longer, cheaper deferred period without breaking cover. The payment term decides whether you’re protected for a few years or right up to retirement — the more comprehensive “to age 68” option costs more but removes the risk of outliving your cover. Together, these choices matter far more than shaving a few pounds off a monthly premium.
Common questions
Is it really essential for office workers? It depends on the employer’s sick-pay arrangement. High-risk roles such as construction and the self-employed carry essentially no income cushion and should treat it as essential. Office and public-sector workers with generous occupational sick pay can view it as optional, but fewer than you’d expect actually have such protection built into their contracts.
Are my payments taxable? Yes. Income protection pays out as earnings, so the monthly sum is subject to tax as income. Factor that into how much cover you need — a 60% replacement figure may net out lower once tax applies, depending on your circumstances.
Can I claim for mental health conditions? Increasingly, yes. Most modern policies cover mental health conditions such as anxiety and depression alongside physical illness and accidents, subject to the policy’s own definitions and deferred period. The key is to read exactly which conditions and definitions a policy covers rather than assuming all are included automatically.
How to buy without overpaying
Start from a realistic figure for what your monthly outgoings need — that, not your full salary, is what cover should protect. Choose a deferred period matched to your savings rather than the cheapest headline package. Compare at least three providers, because pricing for the same risk can vary meaningfully, and disclose your health and smoking status accurately, since non-disclosure can void a claim. Consider whether you need indexation, which raises cover with inflation but increases cost, and be precise about your occupation, because riskier roles attract higher premiums. Review the policy every few years as your earnings, mortgage, and family responsibilities change.
Common mistakes to avoid
The most damaging errors are quiet ones discovered only at claim time. Not disclosing a pre-existing condition is the most common, as it can void the entire policy. Understating how long you could truly manage without income pushes you toward a deferred period you can’t actually sustain. Choosing too short a payment term means protection runs out precisely when a serious illness may last. Overlooking that payments are taxable leads people to set cover too low in real terms. And some treat income protection as interchangeable with critical illness cover, when they protect against different events and shouldn’t be substituted for one another. Addressing these before purchase keeps the policy working when the worst happens.
Bottom line
Income protection is one of the most valuable policies available, especially for the self-employed and those in higher-risk occupations. It replaces 50-70% of income when illness or injury stops you working, and the deferred-period choice is your main levers for controlling cost. Match the deferred period to your savings, choose a payment term that matches how long you’d realistically need protection, disclose honestly, and remember the payouts are taxable. For most working people who don’t already have generous sick pay, it deserves a place well before more expensive or flashier insurance products.
