Most people protect their car, their home, their phone. But ask the same people what would happen to their mortgage, their rent, their family's living costs if they could not work for six months, and the answer is usually a long pause followed by an uncomfortable admission.
Income protection is the insurance product that answers that question. It is consistently the most undersold protection product in the UK, and the one that makes the biggest practical difference when something goes wrong.
This guide explains how it works, who needs it most, and what to look for when you are comparing policies.
What income protection actually is
Income protection is an insurance policy that pays you a monthly benefit if you are unable to work due to illness or injury. It is not a lump sum payment. It is a replacement income that continues to be paid until you either return to work, the policy term ends, or you reach the end of the benefit period you chose when you took out the policy.
It is not the same as payment protection insurance, which is a much narrower product. It is not the same as critical illness cover, which pays a lump sum on diagnosis of a specific condition. Income protection covers a much wider range of reasons why you might not be able to work, including mental health conditions, musculoskeletal problems, and many of the illnesses that do not qualify for critical illness payouts.
The deferred period: when the policy starts paying
Income protection does not pay out immediately when you stop working. There is a waiting period, called the deferred period, before the benefit begins. Common deferred periods are four weeks, eight weeks, thirteen weeks, twenty-six weeks, and one year.
The longer the deferred period you choose, the lower your premiums will be, because the insurer is exposed for less time. The right deferred period depends on how long you could manage without income before the policy needs to kick in. If your employer pays sick pay for six months, a twenty-six week deferred period makes sense. If you are self-employed with no fallback, a shorter deferred period is likely to be more appropriate.
The benefit period: how long it pays
The benefit period is how long the policy will pay out if you remain unable to work. The two main options are a short-term benefit period, typically one or two years, and a long-term benefit period that runs to your chosen retirement age.
Short-term policies are significantly cheaper. They are appropriate for people whose primary concern is covering the mortgage and essential costs during a period of illness that is expected to be temporary.
Long-term policies, which pay until retirement age if necessary, provide much more comprehensive protection but at a higher premium. For anyone who is the primary or sole earner in a household and whose family's long-term financial security depends on their income, a long-term benefit period is worth serious consideration.
Own occupation, suited occupation, and any occupation
This is one of the most important distinctions in income protection and one that is not always explained clearly when policies are sold.
Own occupation cover pays out if you are unable to do your own specific job. If you are a surgeon and you develop a condition that prevents you from operating, own occupation cover pays out even if you could theoretically do other work.
Suited occupation cover pays out if you cannot do your own job or any other job for which you are suited based on your experience and qualifications. This is a broader test that gives the insurer more scope to argue that you should be able to work in some capacity.
Any occupation cover only pays out if you cannot do any work at all. This is the most restrictive definition and typically the cheapest. It is also the least useful for most working professionals.
Own occupation cover is generally the most appropriate for people in professional or skilled roles, and it is the type we would normally recommend discussing with an adviser.
Why self-employed people need it most
Employees generally have a fallback when they are sick. Statutory sick pay, employer sick pay schemes, and sometimes death-in-service benefits provide a level of protection that self-employed people simply do not have.
If you are self-employed and you cannot work, your income stops. Your mortgage does not. Your rent does not. Your business costs may continue even if revenue does not. The financial pressure can be severe very quickly.
For self-employed people, income protection is not a nice-to-have. It is one of the most important financial products available, and the cost of having it is significantly lower than the cost of not having it when you need it.
What affects the premium?
The main factors that affect the cost of income protection are your age, your occupation, your health history, the deferred period you choose, the benefit period you choose, the monthly benefit amount, and the definition of incapacity in the policy.
Occupations are classified by risk, with physical or manual jobs typically attracting higher premiums than office-based roles. A history of certain health conditions may result in higher premiums, exclusions for those conditions, or in some cases a decline.
Frequently asked questions
How much income protection do I need?
Most policies will cover up to around 60% to 70% of your pre-incapacity income. The idea is to replace enough of your income to cover your essential costs without creating an incentive not to return to work. The right amount depends on your monthly commitments and what you could reduce or cut in an emergency.
What is the deferred period?
The deferred period is the time between when you stop working due to illness or injury and when the policy starts paying out. A longer deferred period means lower premiums but a longer gap before you receive any benefit.
Can I get income protection if I am self-employed?
Yes. Income protection is particularly important for self-employed people who have no employer sick pay to fall back on. The policy works the same way, with the benefit replacing a proportion of your normal earnings if you cannot work.
Does income protection cover redundancy?
No. Standard income protection policies cover inability to work due to illness or injury, not unemployment due to redundancy. Separate products exist for redundancy protection, though they are more limited in scope.
What is the difference between income protection and critical illness cover?
Income protection pays a monthly benefit if you cannot work for any health reason. Critical illness cover pays a lump sum on diagnosis of a specific listed condition. They serve different purposes and many people choose to have both.
