Income Protection Insurance UK

1 Step 1

What Is Income Protection Insurance?

Income protection insurance pays you a regular tax-free monthly income if you cannot work because of illness or injury. It is the only protection product designed to replace your salary while you are off work, not just to cover a debt or pay out on death.

Most UK workers have one income, fixed outgoings, and very little fall-back if that income stops. Income protection is the policy that fills the gap between Statutory Sick Pay, any short employer scheme, and the moment you can return to work or retire. Knox Mortgages advises on income protection the same way it advises on mortgages: whole of market, product-led, and structured around the actual financial risk rather than the easiest sale.

For employees, the policy bridges the gap between the day employer sick pay runs out and the day you go back to work. For the self-employed, contractors, and limited company directors, the policy starts even earlier because there is no employer scheme behind you. That gap is where Knox spends most of its protection advice time.

How Income Protection Works

You choose four things when you set up an income protection policy:

A monthly benefit amount. Usually capped at 50 to 65% of your gross earnings. The cap exists so you have a financial reason to return to work once you are well.
A deferred period. The waiting time between stopping work and the first payment. Common options are 1, 4, 8, 13, 26, or 52 weeks. Longer deferred period, lower premium.
A benefit period. How long the policy will keep paying once a claim starts. Either short term (1, 2, or 5 years) or long term (running until retirement age, typically 65 or 68).
An occupation definition. Own occupation, suited occupation, or any occupation. This decides how strict the insurer is when assessing whether you can return to work. Covered in detail below.

Premiums are paid monthly. Cover stays in place as long as premiums are paid and you are within the policy term. Most policies run to a chosen retirement age (60, 65, or 68) and pay out as many separate claims as you need across the term, not just one.

Two extras worth understanding when the policy is set up:

Escalating vs level benefit. A level benefit pays the same monthly amount for the life of the claim. An escalating benefit rises each year, usually in line with RPI or at a fixed 3 to 5%, so a long claim does not erode in real terms. Escalating costs roughly 10 to 20% more in premium.
Indexation of premiums and benefit. Some insurers index the cover amount and premium each year so the protection keeps pace with inflation across the policy term.

Knox builds these settings around your real situation: how long your savings last, what employer sick pay you have, when bonuses or dividends would dry up, and what fixed costs (mortgage, childcare, food, transport) the household needs to keep running.

Why Income Protection Matters

Statutory Sick Pay in the UK is £118.75 a week (2025 rate). That is the legal minimum your employer has to pay you when you cannot work, and it lasts a maximum of 28 weeks. It is roughly £514 a month. For most working households, that figure does not cover the mortgage, never mind food and bills.

If you are self-employed, a sole trader, a CIS contractor, or paying yourself dividends through a limited company, you do not get SSP at all. Your income drops to zero the day you stop working.

Two industry statistics that make the case clearly:

Around 1 in 4 UK workers will be off work for a long period (more than four weeks) at some point in their working life because of illness or injury.
The most common causes of long-term claims are musculoskeletal conditions, cancer, and mental health, not the dramatic accidents people imagine when they think about protection.

Most people insure their car, their phone, and their pet. Their income, which pays for everything else, is the asset they protect last. Income protection corrects that.

What Income Protection Covers

A modern UK income protection policy will pay out for any illness or injury that stops you doing your job, subject to the occupation definition you chose at outset. Common claim categories include:

Musculoskeletal conditions. Back pain, joint problems, repetitive strain, post-surgery recovery. Routinely the largest single category of claims paid.
Mental health. Stress, anxiety, depression, burnout. Most modern policies cover mental health on the same terms as physical illness, with the same deferred period and benefit length.
Cancer. Time off for treatment, recovery, and rehabilitation, even if a critical illness policy has already paid out a lump sum.
Cardiovascular conditions. Heart attack recovery, stroke rehabilitation, ongoing cardiac care.
Major surgery and recovery. Any operation that puts you out of action long enough to trigger the deferred period.
Long-term infectious illness. Including conditions like long Covid where the inability to work is documented by medical evidence.

Income protection does not require a “named condition” diagnosis like critical illness cover does. The test is functional: can you do the material duties of your occupation? If the answer is no and the medical evidence supports it, the policy pays.

What Income Protection Does Not Cover

Income protection is broad, but it is not unlimited. Common exclusions and restrictions:

Unemployment and redundancy. Standard income protection does not pay out if you lose your job. Redundancy cover is a separate, short-term, much weaker product (often called accident, sickness and unemployment, or ASU). Knox is direct with clients about this. Real income protection is for illness and injury. ASU is a different category and rarely worth what people pay for it.
Self-inflicted injury. Deliberate self-harm is excluded.
Pre-existing conditions. Anything you had medical attention for before the policy started can be excluded, loaded, or accepted on standard terms depending on the insurer and the condition. Honest disclosure at application stage is what protects the claim.
Hazardous activities. Some sports and occupations are loaded or excluded (offshore work, professional motorsport, certain types of climbing, military service). Usually loaded as a higher premium rather than excluded outright.
Drug or alcohol related conditions. Most insurers exclude claims directly caused by substance misuse.
Time spent abroad beyond a defined window. Most policies limit how long you can be outside the UK and still claim. Typically 3 to 6 months continuous travel before cover pauses.

Knox pre-underwrites the riskier cases (mental health history, prior musculoskeletal claims, hazardous occupations) with insurers before any application is submitted. That stops a decline going on your record and lets us pick the insurer most likely to accept on standard terms.

Short-Term vs Long-Term Income Protection

The biggest single decision in an income protection case is how long the benefit pays for once a claim starts. Short-term policies are cheap. Long-term policies are the real product.

	Short-term income protection	Long-term income protection
Benefit period	1, 2, or 5 years per claim	Until retirement age (60, 65, or 68)
Typical premium	Significantly cheaper, often 40 to 60% less	Higher, but covers the full risk
Best for	Tight budgets, short-term debt cover, ASU-style needs	Career-long income protection, families, mortgage holders
Risk	Cover runs out mid-claim if illness is long-term	Pays for the entire duration of incapacity
Knox view	Useful as a stop-gap or budget compromise	The default recommendation for most working clients

A long-term policy is what protection is for. If a 38-year-old develops a chronic condition that stops them working at 45, a 5-year benefit period runs out at 50 and leaves 15 to 20 working years uncovered. Knox starts every conversation with long-term cover and only steps down to short-term if affordability genuinely demands it.

Own Occupation vs Suited vs Any Occupation

The occupation definition decides whether the insurer pays the claim. It is the most under-explained part of any income protection sale. The wrong definition turns a good-looking policy into a worthless one at claim time.

Definition	What it means	Who it suits
Own occupation	Pays if you cannot do the material duties of your specific job	Almost everyone. The strongest, most claim-friendly definition. Knox default.
Suited occupation	Pays only if you cannot do your job or any job your training, experience, or education suits you for	Sometimes used for higher-risk occupations or non-standard cases
Any occupation	Pays only if you cannot do any job at all, anywhere	Avoid unless there is no own-occupation alternative. Very low claim rate.

A surgeon with a hand injury cannot operate. Under own occupation, the policy pays. Under any occupation, the insurer can argue the surgeon could work as a lecturer or consultant, and decline the claim. Knox places own occupation cover in almost every case. If an insurer will not offer it, that is a reason to look at a different insurer, not to settle for a weaker definition.

Income Protection for the Self-Employed

If you work for yourself, income protection is not a nice-to-have. It is the only safety net you have. There is no SSP, no employer sick pay scheme, no group cover sitting in the background. The day you stop working, your income stops with it.

The structure is the same as for an employee, but the deferred period decision changes. Most self-employed clients pick a shorter deferred period (4, 8, or 13 weeks) because there is no employer scheme to bridge the gap. Knox usually models two scenarios: how long your business savings genuinely last, and how long you can survive on partner income or other household resources, then picks the deferred period that closes the gap without paying for cover you do not need.

Three points self-employed clients consistently get wrong:

Insuring drawings rather than profit. Most insurers will base the maximum benefit on net profit (sole trader) or salary plus dividends (limited company). If you under-draw to leave money in the business, your benefit cap is calculated on what the business earned, not what you paid yourself. Document the figures properly at application stage.
Forgetting that a sick contractor still has overheads. If the business has rent, vehicle finance, software subscriptions, or staff to pay, the cover needs to factor those in alongside the household budget.
Underestimating mental health and burnout risk. Self-employed workers carry more stress, more cash-flow exposure, and longer working hours. Mental health is the fastest-growing claim category in income protection. Cover has to be set up to recognise it, not exclude it.

If you are self-employed and your mortgage advice and protection advice are sitting with two different firms, that is a structural problem. Knox handles both. See self-employed mortgage advice for sole traders and freelancers and limited company director mortgages for the borrowing side, and we layer the protection in on the same case.

Income Protection for Contractors (CIS, Limited, Umbrella)

Contractors sit in the gap between employee and self-employed. Day-rate workers, CIS subcontractors, umbrella PAYE contractors, and limited company contractors each face a different income structure, and the protection has to match.

CIS contractors. Paid net of tax under the Construction Industry Scheme. Income is treated as self-employed for protection purposes. Most insurers will base the benefit on declared net taxable profit, not gross day rate. Documentation matters: SA302s, tax overviews, and CIS payment statements all support the application. See CIS contractor mortgage advice for related borrowing structure.
Limited company contractors. Usually salary plus dividends. Insurers will combine both for the benefit cap, often plus retained profit if the contract has been running long enough. Setup is identical to self-employed director cases.
Umbrella PAYE contractors. Paid through an umbrella company, taxed at source. Treated as employees for income protection purposes, which means SSP applies for the umbrella period, but contracts often end with no notice. A short deferred period (4 to 8 weeks) usually makes more sense than the 13-week minimum that suits permanent staff.
Day-rate contractors generally. The defining risk is contract gaps. Income protection covers illness and injury, not contract drought. For contract-end risk, savings and a rolling cash buffer are the answer, not a protection product.

If you are working day-rate, mortgage and protection advice should sit together. Knox handles contractor cases end to end, see day-rate contractor mortgage advice for the lending side and we layer the income protection on the same conversation.

Income Protection vs Critical Illness Cover

Income protection and critical illness cover sit next to each other but solve different problems. Most clients eventually take both. The choice matters more for clients who can only afford one.

	Income protection	Critical illness cover
Pays when	You cannot work due to illness or injury	You are diagnosed with a listed condition (cancer, heart attack, stroke, etc.)
Payout	Monthly tax-free income	Tax-free lump sum
Trigger	Inability to work, supported by medical evidence	Specific medical diagnosis from the policy list
Length of payout	For as long as you cannot work, up to retirement	Single one-off payment, then policy ends
Mental health	Covered by most modern policies	Almost never covered
Common conditions paid	Musculoskeletal, mental health, cancer, surgery	Cancer, heart attack, stroke, MS
Best for	Replacing income across a long career	Clearing the mortgage or covering a major medical bill

Knox view: if a client can only afford one, income protection wins for most working-age earners. It pays for the broader range of claim events, it covers mental health, and it keeps paying for as long as you cannot work. Critical illness cover is a sharper tool for paying off the mortgage on a serious diagnosis. Where the budget allows, layer both. See critical illness cover advice for the lump sum side.

What Income Protection Costs

Income protection premiums depend on age at outset, smoker status, occupation class, deferred period, benefit period, and the cover amount. Indicative monthly premiums for a healthy non-smoker insuring £2,000 per month of benefit, long-term to age 65, own occupation, with an escalating benefit:

Age at start	Office worker (Class 1), 13-week deferred	Tradesperson (Class 3), 13-week deferred
25	£18 to £28	£32 to £48
30	£22 to £34	£40 to £60
35	£28 to £42	£52 to £78
40	£36 to £56	£68 to £105
45	£52 to £78	£95 to £150
50	£75 to £115	£140 to £220
55	£115 to £180	£220 to £340

Adjustments worth understanding:

Shorter deferred period adds cost. Moving from 13 weeks to 4 weeks typically adds 20 to 35% to the premium. Moving to 1-week deferred can almost double the cost.
Short-term benefit period drops cost materially. A 5-year benefit period instead of “to age 65” can cut the premium by 40 to 60%.
Smoking adds 30 to 80%. Defined as any nicotine use in the last 12 months, including vaping with most insurers.
Occupation class is the biggest mover. A desk-based professional sits in the cheapest class. A roofer or scaffolder sits in the highest, and some insurers will not quote at all.

Premiums vary by 30 to 50% across insurers for identical cover. Whole-of-market access means pulling quotes from every major UK income protection provider rather than one panel.

Industry Claims Stats

The Association of British Insurers publishes annual claims data for protection products. Recent UK industry figures for income protection:

Around 96% of income protection claims are paid each year.
The remaining 4% of declines are overwhelmingly driven by non-disclosure of medical history at application stage, not by insurers refusing to honour valid claims.
Average claim duration varies widely. Mental health and musculoskeletal claims average 6 to 18 months. Cancer claims often run 12 to 36 months. Some claims continue to retirement.

The takeaway is simple: insurers pay income protection claims at very high rates when the policy was set up honestly. The job at application stage is to disclose every relevant medical fact, even the ones that seem trivial, so the insurer cannot use non-disclosure to challenge a future claim. Knox walks every client through the application questions in detail and runs pre-underwriting on anything ambiguous before the policy is submitted.

Anonymised Claim Scenarios

Three realistic claim scenarios, with the numbers worked through to show how the policy behaves in practice. Names and details changed.

Case A. Self-employed plumber, age 39. Took out long-term income protection at £1,800 per month benefit, 8-week deferred, own occupation, to age 65. Premium £58 a month. Three years in, slipped a disc on site. Off work for 11 months. Claim paid from week 9 onwards, total payout across the claim around £19,800. Cover continued unchanged after recovery, so the same protection is in place for any future claim.

Case B. Limited company director, age 44. Salary £12,570, dividends £40,000. Income protection set up on combined £52,570 income, £2,400 monthly benefit, 13-week deferred, level benefit, to age 60. Premium £74 a month. Diagnosed with stage 2 cancer at 47. Claim paid from week 14 of being unable to work, ran for 19 months across treatment and recovery. Total claim payout around £45,600. Critical illness lump sum (separate policy) cleared the mortgage at the same time.

Case C. Office-based employee, age 32. Employer scheme paid full salary for 6 months. Took out income protection with a 26-week deferred period to start exactly when the employer scheme ended. £1,500 monthly benefit, escalating, to age 68. Premium £24 a month. Off work for 14 months with severe anxiety and depression. Employer scheme paid the first 26 weeks. Income protection paid weeks 27 to 60. Total income protection claim around £21,000.

The pattern in all three: the deferred period was deliberately matched to existing income (savings, employer scheme, partner income) so the cover was not over-paying for ground that was already covered.

How Knox Advises on Income Protection for Self-Employed and Limited Company Directors

Knox is whole of market and FCA-regulated for mortgage and protection advice. We quote across every major UK income protection insurer rather than a tied panel, and we build cover around the actual financial risk: how long savings last, what employer or business cover already exists, what the fixed monthly outgoings are, and what other protection (life, critical illness, FIB) is already in place.

For limited company directors there is a more tax-efficient route worth considering. Executive income protection lets the company pay the premiums as a tax-deductible business expense, with the benefit paid into the business and then on to you as continued PAYE income. For higher-earning directors this often works out materially cheaper net of tax than personal cover. See executive income protection for limited company directors for the structure.

The same logic applies to life cover for directors. Relevant life insurance sits alongside executive income protection as the company-funded equivalent of personal life cover. Knox sets the two up together where they fit the case.

The standard process:

Establish the income, the existing cover, and the household budget.
Calculate the realistic gap and the deferred period that bridges it.
Decide own vs suited occupation and short vs long-term benefit.
Quote across the whole market, including executive structures for directors.
Pre-underwrite anything risky with insurers before the application is submitted.
Submit the application, handle underwriting, and place the policy.

There is no fee for Knox’s protection advice. Income protection is commission-paid by the insurer. Knox is transparent about commission structures on request.

Frequently Asked Questions

Do I really need income protection if I have savings?

Savings are useful but rarely enough. A 6-month emergency fund covers a 6-month claim. The average long-term claim runs much longer than that, often 12 to 36 months. Income protection takes over once savings are exhausted and keeps the household running for as long as you cannot work, which is exactly the financial gap savings cannot realistically fill on their own.

Can I get income protection if I am self-employed?

Yes. Self-employed clients are some of the most under-protected and most in need of cover. Insurers will quote on the basis of net profit (sole trader) or salary plus dividends (limited company). Documentation includes SA302s, tax overviews, and accountant-prepared accounts. Knox places income protection for self-employed clients as a routine part of the practice.

What is the difference between income protection and ASU (accident, sickness and unemployment) cover?

Income protection is a long-term, regulated insurance product that pays for as long as you cannot work due to illness or injury, often to retirement age. ASU is a short-term, often general-insurance product that pays for 12 or 24 months and usually includes redundancy. ASU is cheaper and weaker, with stricter exclusions and a far lower claim rate. Knox treats them as different products: real income protection first, ASU only if budget genuinely demands it.

Does income protection cover redundancy?

No. Standard income protection does not pay out for redundancy or unemployment. If you specifically want redundancy cover, that is a separate, short-term ASU policy. Be aware that ASU cover is harder to claim on, has a much lower payout rate, and is widely seen as poor value compared to building a redundancy savings buffer.

Does income protection cover mental health?

Most modern UK income protection policies cover mental health on the same terms as physical illness, including the same deferred period and benefit length. Mental health is now one of the largest claim categories. Older policies and some short-term ASU products restrict it. Knox checks the policy wording explicitly before recommending.

How much income protection can I get?

Most insurers cap the benefit at 50 to 65% of your gross earnings. The cap exists so you have a financial reason to return to work once you are well. Knox calculates the maximum eligible benefit and then often sets the policy below it, where the household budget genuinely sits, to keep the premium efficient.

What deferred period should I choose?

Match the deferred period to the income you already have. If your employer pays full sick pay for 26 weeks, a 26-week deferred period saves you from paying for cover you do not need. If you are self-employed with three months of savings, an 8 or 13-week deferred period usually fits. Shorter deferred periods cost more, so do not shorten without reason.

What is the difference between own occupation and any occupation cover?

Own occupation pays out if you cannot do the material duties of your specific job. Any occupation pays out only if you cannot do any job at all, anywhere. Own occupation is far easier to claim on and is what Knox recommends in almost every case. Any occupation policies look cheaper but have a much lower claim rate.

Will my income protection pay out if I have a pre-existing condition?

Pre-existing conditions can be excluded, loaded, or accepted on standard terms depending on the condition and the insurer. Honest disclosure at application stage is what protects the claim later. Knox pre-underwrites medical history with insurers before any application is submitted, so we know exactly what cover the policy will offer before you sign.

How quickly does income protection start paying?

The first payment lands one month after the deferred period ends. So a 13-week deferred policy makes its first payment around week 17 of being unable to work. The insurer needs medical evidence of incapacity and, for self-employed clients, evidence of lost income. Most legitimate claims are confirmed within 4 to 8 weeks of the deferred period ending.
