Most people insure their car and their home, but far fewer insure the thing that pays for everything: their income. Income protection does exactly that. This guide explains what income protection insurance is, how it works, how it differs from other cover, and who should consider it.

What income protection is

Income protection insurance pays you a regular, usually tax-free income if you are unable to work because of illness or injury. Rather than a one-off lump sum, it replaces part of your earnings, typically a percentage of your usual income, for as long as you are unable to work, up to the end of the policy term. It is designed to keep money coming in so you can pay the mortgage and bills while you recover.

How it works

When you take out income protection, you choose the level of cover, usually a proportion of your income, a deferred period before payments start, and the length of time payments can continue. If illness or injury stops you working, you claim, and after the deferred period the insurer pays you a regular income until you can return to work, the policy ends, or you reach the end of the agreed payment period, whichever comes first.

The deferred period

The deferred period is the waiting time between becoming unable to work and the payments starting, often ranging from a few weeks to several months. A longer deferred period makes the cover cheaper, but means you must support yourself for longer before payments begin, perhaps using sick pay or savings. Choosing the deferred period is about matching it to how long you could manage on other resources before you would need the income protection to kick in.

How much it pays

Income protection does not replace your whole salary; it usually covers a percentage, often somewhere around half to two thirds of your gross income, because the payouts are typically tax-free and there is an expectation that you should not be better off not working. This still provides a substantial safety net. When deciding how much cover to take, think about the essential outgoings you would need to meet if your earnings stopped.

Short-term versus long-term cover

Income protection comes in two broad forms. Short-term income protection pays out for a limited period, such as one or two years per claim, and is cheaper. Long-term, or full, income protection can pay out until you recover, retire or the policy ends, providing far more security if you were unable to work for a long time. Long-term cover costs more but offers the protection that matters most in a serious, lasting illness.

How it differs from other cover

Income protection is often confused with critical illness cover and with payment protection products, but it is different. Critical illness pays a lump sum for specific listed conditions, while income protection pays a regular income for almost any illness or injury that stops you working, as our guide to critical illness cover explains. Because it covers a much wider range of reasons for being off work, many advisers regard income protection as the foundation of personal protection.

Who should consider it

Income protection is worth considering for anyone who relies on their earnings and would struggle if those earnings stopped, which is most working people. It is especially valuable for the self-employed, who usually have no employer sick pay to fall back on, and for anyone with a mortgage and limited savings. If your household could not manage for long on statutory sick pay or savings alone, income protection fills a serious gap.

Checking your existing safety net

Before buying, check what you already have. Some employers provide sick pay or even group income protection, though usually only for a limited time. Statutory sick pay is modest and time-limited. Understanding how long your existing arrangements would support you helps you choose the right deferred period and cover length, so your income protection picks up where your other safety nets run out rather than duplicating them, in line with our guide to working out your protection needs.

Own occupation versus any occupation

A crucial detail in income protection is how the policy defines being unable to work. The best definition is own occupation, which pays out if you cannot do your own job. Weaker definitions, such as any occupation, only pay if you cannot do any job at all, which is much harder to claim on. When comparing income protection, the definition of incapacity matters as much as the price, because it determines how readily the cover would actually pay out.

Guaranteed versus reviewable premiums

As with other protection, income protection premiums can be guaranteed, staying the same throughout, or reviewable, meaning they can change. Guaranteed premiums cost a little more at the start but give certainty over the long term, which is valuable for a policy you may hold for decades. Reviewable premiums can start cheaper but may rise. Knowing which you are buying helps you judge the true long-term cost rather than just the opening price.

How income protection works with other support

Income protection is designed to sit alongside, not replace, other support. Statutory sick pay and any employer sick pay usually come first, which is why a deferred period is set to match how long those last. The cover then picks up when they run out. Because payouts are usually tax-free and capped at a proportion of your earnings, the system is designed so you are supported without being better off not working, which keeps the cover sustainable.

How a claim works

To claim on income protection, you tell the insurer when illness or injury stops you working and provide medical evidence to support the claim. After your chosen deferred period, payments begin and continue while you remain unable to work under the policy's definition, up to the agreed payment period. Many insurers also offer rehabilitation and early support to help you recover and return to work, since that outcome benefits both you and them. This combination of regular income and practical support is a large part of what makes income protection so valuable when a long illness or injury would otherwise threaten your finances.

For most working people, protecting the income that pays for everything else is one of the most sensible and overlooked forms of cover there is.

In short

Income protection pays a regular, usually tax-free income, often around half to two thirds of your earnings, if illness or injury stops you working, after a deferred period you choose. It differs from critical illness cover, which pays a lump sum for listed conditions, by covering almost any illness or injury. Long-term cover offers the most security, and it is especially valuable for the self-employed and anyone without much employer sick pay.
