What the contract actually does

Income protection is a contract between you and an insurer. In exchange for the premium, the insurer agrees to pay a regular monthly benefit if illness or injury leaves you unable to work, tested against the policy’s written incapacity definition. Payments begin only after the deferred period — the waiting time you choose at the outset — and continue until you recover, the benefit period ends, or the policy reaches its end age, whichever comes first. Standard cover has no savings element: if the policy ends without a claim, nothing is returned. Before you buy, the FCA’s conduct rules require the insurer to give you pre-contract information — the Insurance Product Information Document and the full wording — and a statutory cancellation period afterwards. ^[3]

Two structural points shape everything else. First, income protection is capacity-based, not event-based: any illness or injury can qualify, because the claim tests what you can no longer do rather than matching a diagnosis to a list — which is exactly how it differs from critical illness cover. Second, the monthly benefit is capped at a percentage of your earnings, so the documentation of your income at application matters as much as the medical questions. The FCA’s Consumer Duty requires insurers to design, price and explain products to deliver good outcomes for retail customers. ^[4] This guide stays on working out how much income protection you need.

How a claim works

A claim starts when you notify the insurer that illness or injury has stopped you working. You supply medical evidence — usually GP records and, where needed, a specialist report — and the insurer tests two things: that your condition meets the policy’s incapacity definition, and that you have been continuously unable to work through the whole deferred period. The Financial Ombudsman Service’s published decisions show both tests applied in real cases: a claim declined where the medical evidence did not support total incapacity for the insured occupation, another where an absence fell inside a 26-week deferred period and a work-related-stress exclusion applied, and a third turning on the exact wording of an own occupation definition. ^[13][14][15] On longer claims, insurers review continuing benefit periodically, and payments stop when the evidence no longer supports the definition. This guide discusses conditions only as they relate to cover and claims — for anything about symptoms, diagnosis or treatment, see the NHS.

Your disclosure rights

The Consumer Insurance (Disclosure and Representations) Act 2012 replaced the old duty to volunteer everything with a duty to take reasonable care to answer the insurer’s questions accurately and not to mislead. ^[6] The Insurance Act 2015 added the parallel duty of fair presentation for commercial insurance, which matters for executive and business income protection paid for by a company. ^[7] For consumers, CIDRA means an insurer cannot refuse a claim over an innocent and irrelevant answer, but can reduce or refuse claims for a careless or deliberate misrepresentation. This matters enormously for income protection, because a claim can be tested against answers given years earlier, and because underwriters assess anything that could cause future absence — not only serious diagnoses.

Alongside the statutes, the FCA’s conduct rules require insurers to give you the product information document and full wording before you buy, and to handle claims fairly and not reject them unreasonably — the rule the Ombudsman quotes when deciding income protection disputes. ^[3][14] The Consumer Duty sits above all of it: insurers and intermediaries must act to deliver good outcomes for retail customers, covering how products are designed, priced, explained and serviced. ^[4] You can check that any insurer, adviser or broker you deal with is authorised on the Financial Services Register. ^[2]

The arithmetic, in the right order

Start with the essentials: list the monthly outgoings that would not stop if you could not work — rent or mortgage, council tax, utilities, food, debt payments, childcare and travel. That total, not your salary, is the number the benefit needs to approach. Then subtract what already exists: contractual employer sick pay (check your contract, not your assumptions, and note when it steps down), Statutory Sick Pay at £123.25 a week for eligible employees for up to 28 weeks, savings you are genuinely prepared to commit, and any cover you already hold — including an employer group income protection scheme, which many people forget they have. The remainder is the monthly gap. Finally, apply the insurer’s cap: policies limit the benefit to a percentage of your earnings, so the figure you can buy may be lower than the gap you calculated — which is when the deferred period and your savings do the rest of the work.

Write the calculation down with dates and sources, and revisit it after every major change — a new mortgage, a new child, a pay rise or a paid-off loan all move the number. Whatever the specifics of working out how much income protection you need, the discipline that protects you is always the same: get the insurer’s position in writing, keep the documents with the policy, and make sure the people who would help you claim know the policy exists and where the paperwork lives.

What moves the price

Income protection premiums are set from your age, your occupation — insurers grade jobs by how likely they are to cause absence — your answers on health, lifestyle and smoking, the monthly benefit, the deferred period, the benefit period and the premium type. Guaranteed premiums stay fixed for the term; reviewable premiums can be re-priced by the insurer at set intervals; age-banded premiums rise on a published schedule. A longer deferred period cuts the premium substantially because the insurer never pays for shorter absences. Average premium figures circulate widely online, but an average built from different ages, occupations and benefit levels cannot predict your quote — treat any average without a named source and a date as unusable [STATISTIC REQUIRED: current average UK income protection premium, named source].

One genuine lever exists beyond the cover design itself: matching the deferred period to your real sick pay. If your employer pays three months of full pay, a four-week deferred period makes you pay twice for the same weeks. Written quotes against an identical specification — same benefit, same deferred period, same occupation class, same premium type — are the only honest comparison. Pay-out statistics matter when weighing price against reliability: ABI and GRiD data shows 97.9 per cent of individual protection claims were paid in 2024 and again in 2025. ^[11][12]

If something goes wrong

If a claim is declined, delayed, or continuing benefit is stopped, complain to the insurer first, in writing, and ask two precise questions: which clause of the policy wording the decision rests on, and exactly which evidence failed the incapacity definition or the deferred-period requirement. The insurer must investigate and give a final response. If you are still unhappy after that response — or after eight weeks — the Financial Ombudsman Service can decide the dispute free of charge, and its published income protection decisions show it requiring insurers to restart benefit and add interest where a termination was not justified by the evidence. ^[5][13] If the insurer itself fails financially, the Financial Services Compensation Scheme may protect eligible policyholders.

1. Read the IPID before you buy The Insurance Product Information Document summarises what is and is not covered; the full wording governs.
2. Check the incapacity definition first Own occupation is the strongest definition for the policyholder; suited and any occupation make claims harder.
3. Match the deferred period to your sick pay The deferred period should end when your employer sick pay and savings would run out — no sooner.
4. Document your income accurately The benefit is capped as a percentage of earnings; overstated income at application unravels at claim.
5. Answer health questions with reasonable care Ask for clarification in writing if a question is ambiguous; keep a copy of your answers.
6. Keep every document Dates, fit notes, reference numbers and written decisions are what resolve disputes later.

Income protection, sick pay and the safety net

Income protection sits inside a wider financial safety net, and it helps to see what the other layers provide. Employed people who are too ill to work can qualify for Statutory Sick Pay — £123.25 a week at the time of writing, payable by the employer for up to 28 weeks to eligible employees. ^[8] After that, the state routes are Universal Credit and, for people with limited capability for work, Employment and Support Allowance — each with its own eligibility rules and assessments. ^[9][10] Those figures are the context for the gap a policy is designed to fill: outgoings rarely pause while income does. The insurance products are complementary, not interchangeable — income protection replaces the monthly pay packet, critical illness cover pays a single lump sum for defined conditions, and life insurance pays others after death.
