Income protection insurance explained

Of all the protection products available to homeowners and workers, income protection is the one most people know least about, and arguably the one that deserves the most attention.

Life insurance pays out when you die. Critical illness cover pays out if you are diagnosed with a serious condition. But statistically, the most common reason people find themselves unable to meet their financial commitments is not death or a dramatic diagnosis: it is an extended period of being too ill or injured to work. Income protection is the product designed specifically for that scenario.

What is income protection insurance?

Income protection insurance pays you a regular monthly income if you are unable to work due to illness or injury. Unlike a one-off lump sum, it replaces a portion of your earnings for as long as you remain unable to work, up to the end of the policy term, which can be set to run until your chosen retirement age.

It is not the same as payment protection insurance, or PPI, which was widely mis-sold in the 2000s and had very limited, short-term cover. Income protection is a fundamentally different product: more comprehensive, more flexible, and genuinely designed to provide meaningful long-term support.

How does it work?

You choose an amount of monthly benefit, typically up to 60% to 70% of your pre-tax income. If you become unable to work due to illness or injury, the policy begins paying that amount after a waiting period called the deferred period.

The deferred period is the gap between when you stop working and when the payments begin. Common options are one month, three months, six months, or twelve months. A longer deferred period reduces your premium, because the insurer is exposed to risk for a shorter total duration. The right deferred period depends on how long you could cover your outgoings from savings or employer sick pay before you need the policy to kick in.

Once the deferred period has passed and your claim has been validated, the monthly payments continue for as long as you remain unable to work, not just for a year or two, but potentially for decades if necessary. This is the defining feature of income protection: its duration.

Why does the duration matter so much?

Most people think of illness and injury in terms of short-term recovery (a few weeks, perhaps a few months, then back to normal). And most illnesses do resolve within that timeframe.

But the scenarios that create genuine financial catastrophe are the ones that do not. A mental health condition that prevents someone from working for two years. A spinal injury that ends a physical career permanently. A condition that improves enough to leave hospital but not enough to return to a demanding job.

In these situations, a short-term sick pay arrangement, whether from an employer or a critical illness lump sum used up over time, eventually runs out. If you are still unable to work when the money runs out, you are in serious difficulty. Income protection is the product that prevents that outcome.

Employed vs self employed

For employed people, the starting point for assessing income protection need is to understand your employer's sick pay provision.

Some employers offer generous sick pay: six months or a year at full or partial salary. If your employer sick pay runs to six months, a six-month deferred period on your income protection policy means the policy picks up exactly when the employer cover ends, and your premium is lower as a result.

Many employers offer far less: statutory sick pay only, which is currently £116.75 per week. At this level, the financial gap between what you earn and what you receive while ill is significant and appears very quickly.

For self employed people, there is no employer sick pay at all. Income stops on the day you cannot work, and the only safety net is your own savings or an income protection policy. Self employed buyers arguably have a greater need for income protection than employed workers, and this is worth understanding clearly before deciding not to arrange it.

Own occupation vs suited occupation vs any occupation

The definition of incapacity in your policy (what standard you must meet to trigger a claim) is one of the most important features to understand and compare.

Own occupation policies pay out if you are unable to do your specific job. A surgeon who can no longer perform surgery due to a hand injury would be covered, even if they could theoretically work in a different role. This is the most favourable definition for the policyholder and the most appropriate for professionals and skilled workers whose earning capacity is tied to a specific role.

Suited occupation policies pay out if you are unable to do your job or any similar job for which you are reasonably qualified by training and experience. The surgeon in the previous example might not qualify, because they could work as a medical consultant or trainer.

Any occupation policies only pay out if you are unable to do any work at all (the most restrictive definition). These policies have the lowest premiums but the highest bar for claiming successfully. In most cases, they are not the most appropriate choice for working professionals.

The definition used in a policy is a critical factor in its value. A cheap policy with an any occupation definition may not pay out in many of the scenarios where you would need it most.

What does it cost?

Income protection premiums are determined by your age, your health, your occupation, whether you smoke, the benefit amount, the deferred period, and the policy term.

Occupation matters significantly. A desk-based professional is statistically less likely to suffer a work-ending illness or injury than someone in a physically demanding job, and premiums reflect this. A teacher or an accountant will pay less than a manual worker for equivalent cover.

As a rough guide, a healthy non-smoker in a professional role in their early thirties might pay between £25 and £60 per month for income protection covering £2,000 per month of benefit with a three-month deferred period to retirement age. The range is wide because the variables are significant. An adviser can get you accurate quotes for your specific situation.

Income protection vs critical illness cover

These two products are often compared, and the question of which to prioritise if budget is a constraint comes up regularly. They serve different purposes.

Critical illness cover pays a one-off lump sum on diagnosis of a specified serious condition. It is very useful for absorbing the immediate financial impact of a serious illness, such as paying off the mortgage, funding private treatment, or restructuring your finances.

Income protection pays a monthly income for as long as you cannot work, regardless of what the underlying condition is. It does not require a diagnosis from a specific list: any illness or injury that prevents you from working triggers the claim.

In terms of breadth of coverage, income protection is wider. It covers any reason you cannot work, whereas critical illness is limited to the conditions on the policy's list. On the other hand, a critical illness payout is typically larger than the monthly benefit from income protection, making it more useful for large one-off costs like repaying the mortgage.

Ideally, you have both. If budget requires a choice, the right answer depends on your individual circumstances: your employer sick pay, your savings, your occupation, and your financial commitments. An adviser can help you work through the decision clearly.

The short version

Income protection insurance pays a monthly income if you are unable to work due to illness or injury, for as long as you remain unable to work. It is the product most directly designed to protect your mortgage and your financial life against the most statistically likely threat: an extended period of being unable to earn.

It is often overlooked in favour of life insurance and critical illness cover, which address less probable but more emotionally vivid scenarios. For many buyers, and especially for the self employed, income protection is often the product most worth considering first, not last.

The cost varies significantly by individual circumstances. Speaking to an adviser will give you an accurate quote and help you understand whether the benefit amount, deferred period, and policy definition are right for your situation.
