Income Protection Insurance: Is It Worth It, and Do You Really Need It?

Income protection is consistently cited by financial advisers as the most undervalued protection product on the market — and consistently bought by the fewest people. In this guide, I explain exactly what income protection does, why it is arguably more important than life insurance for most working-age adults, how it differs from critical illness cover and the largely discredited PPI, what a deferred period means, and whether it is worth the cost if you already have employer sick pay.

What does income protection insurance actually cover?

Income protection insurance pays you a regular monthly income — typically 50–70% of your pre-illness gross salary — if you are unable to work due to illness or injury. Crucially, unlike critical illness cover, it is not limited to a specific list of conditions. It pays if you cannot do your job, whatever the medical reason.

The policy continues paying until one of three things happens: you return to work, the policy term ends, or you reach a specified maximum claim period (some policies are limited to one or two years per claim; others pay until your selected retirement age). The difference between a "short-term" and "long-term" income protection policy is significant — short-term policies limit individual claims to a set period, while long-term policies pay indefinitely until you can return to work or retire.

For most people who want genuine financial protection against long-term illness, a long-term income protection policy with an "own occupation" definition (more on this below) is the gold standard.

How much of my salary will income protection pay out?

Insurers will typically allow you to protect up to 60–70% of your pre-illness gross income. The cap exists deliberately — the policy is designed to help you manage financially during illness, not to make illness financially preferable to working. Combined with any state benefits (Statutory Sick Pay, Employment and Support Allowance), most people can replace a meaningful proportion of their take-home pay during a period of illness.

The benefit you receive is usually tax-free (in most structures), which means 60% of gross income typically equates to a higher proportion of your actual take-home pay. For example, a basic rate taxpayer might receive 60% of gross, which may be 75–80% of their net take-home pay.

We calculate the benefit level you actually need based on your specific outgoings — mortgage, bills, family costs — rather than applying a generic percentage. The goal is not to replace your full lifestyle; it is to ensure the essentials are covered while you recover.

How long does income protection pay out for?

This depends entirely on the policy you take out, and it is one of the most important variables to understand when comparing policies.

Short-term income protection: pays for a limited period per claim — typically one or two years. After the claim ends, you are left without income from the policy even if you are still ill. These policies are cheaper, but they provide limited protection against long-term illness.

Long-term income protection: pays until you return to work, reach the end of your policy term, or die — whichever comes first. If you set your policy term to coincide with your intended retirement age, you are covered for the entirety of your working life. This is the type of policy I recommend to most clients, because the scenarios that are most financially damaging are precisely the long-term ones — a permanent or very long-duration inability to work.

The NHS statistic that most people find sobering: the average claim duration on income protection policies runs to several years, not weeks. This makes the "long-term vs short-term" distinction one of the most consequential decisions in choosing a policy.

What is a deferred period and how does it work?

The deferred period (also called the waiting period or excess period) is the length of time between when you stop working and when your income protection policy begins paying out. Common options are four weeks, eight weeks, thirteen weeks, twenty-six weeks, and fifty-two weeks.

Choosing a longer deferred period reduces your premium — because the insurer is covering a shorter period of your potential claim. The right deferred period depends on your situation:

• If your employer pays full sick pay for six months, a twenty-six week deferred period means the policy kicks in exactly when employer sick pay stops — you have no gap, and you pay a lower premium than a shorter deferred period
• If you are self-employed with no sick pay at all, a shorter deferred period — four or eight weeks — means you receive income from the policy almost immediately after illness strikes
• If you have savings sufficient to cover three months of expenses, a thirteen-week deferred period balances cost against protection

We always start a protection review by mapping out your existing income sources — employer sick pay, savings buffer, state benefits — and then design the deferred period to complement them, rather than applying a generic recommendation.

Is income protection worth it if I already have sick pay through work?

Yes — for most people — and here is why. Employer sick pay is finite. The most generous employer sick pay schemes typically cover six months at full pay and then six months at half pay. After that, statutory sick pay of £116.75 per week (as of 2026) is all that remains. For a mortgage holder, that sum covers a fraction of a typical monthly mortgage payment.

Income protection can be designed to complement your employer sick pay precisely. By setting a deferred period that matches the end of your employer sick pay, the policy starts the moment your employer's support ends — creating a seamless income stream. The premium for a policy with a twenty-six week deferred period is typically significantly lower than one with a four-week deferred period, making it cost-effective to design the policy around your existing benefits rather than ignoring them.

One important note: if you change jobs, your sick pay provision may change too. Policies should be reviewed whenever employment circumstances change significantly.

What is the difference between income protection and PPI?

Payment Protection Insurance (PPI) became notorious for being mis-sold on a massive scale in the UK — and its reputation coloured many people's view of income protection insurance, which is a completely different product.

PPI was typically sold alongside a specific loan or credit agreement to cover repayments if the borrower could not work. It covered specific repayments rather than income; it was often expensive relative to its benefits; it had restrictive terms and significant exclusions; and it was widely sold to people who did not need it or could not claim on it.

Proper income protection insurance covers a proportion of your total income — not just a specific debt repayment. It is underwritten individually at the point of application, so you know upfront what is and is not covered. It is regulated differently, with FCA consumer protections applying. And it is advised and recommended to you based on a genuine needs assessment rather than sold as an add-on to a credit product.

If you were put off income protection by the PPI scandal, it is worth revisiting the question with fresh eyes — the products are fundamentally different in purpose, structure, and regulation.

Can the insurer cancel my income protection policy?

No — not without cause, once your policy is in force. Most income protection policies are guaranteed renewable, meaning the insurer cannot cancel your policy, increase your premium (beyond any agreed indexation), or change your terms as long as you continue paying the premiums.

The risk that concerns most people — "what if I fall ill and the insurer refuses to cover me for that condition when I renew?" — does not apply to individual income protection policies, because they do not renew annually. Your policy is agreed once, at inception, and runs continuously until the end of its term.

What the insurer can do is decline to pay a specific claim if the illness relates to something that was excluded at the point of application (usually a pre-existing condition that was not disclosed or was specifically excluded). This is exactly why honest and complete disclosure at application time is essential — and why we review your medical history carefully before making any recommendation.

Do self-employed people need income protection?

More than anyone. If you are self-employed and you cannot work, your income stops — immediately, completely, and with no employer safety net. There is no statutory sick pay for the genuinely self-employed (Class 2 NI payers), and Employment and Support Allowance — the main state benefit for those who cannot work — is means-tested and modest.

Yet self-employed people are statistically among the least likely to have income protection in place. The combined facts of no safety net and lower uptake make self-employed workers highly financially exposed to illness or injury.

Insurers do assess self-employed income differently — typically looking at your net profit over the last one to three years, smoothed to account for variable income. For newly self-employed clients, some insurers require a minimum trading period before offering cover. We navigate these nuances and find insurers who are most appropriate for your employment structure.

Does income protection cover redundancy?

Standard income protection insurance does not cover redundancy — it covers inability to work due to illness or injury only. Redundancy cover is a different product (sometimes called Accident, Sickness and Unemployment or ASU insurance).

ASU policies that include unemployment cover typically have significant restrictions: a minimum employment period before a claim can be made, exclusions for voluntary resignation or self-imposed redundancy, and limited claim durations. They are useful for some clients but are not a substitute for long-term income protection against illness and injury.

For most clients, the most valuable protection is against long-term illness — the scenario where you are not made redundant but genuinely cannot work due to health. That is what income protection covers, and it is the risk that most people underestimate.
