Income protection and critical illness cover solve different problems. A practical framework for recommending the right one, or both, and documenting why.

Protection conversations often collapse two genuinely different products into one pitch. Income protection and critical illness cover both come up when a client's ability to earn or their health is at risk, but they solve different problems, pay out in different ways, and suit different circumstances. Recommending one over the other, or both, needs an actual reason, not a default.
Critical illness cover pays a single lump sum on diagnosis of a specified serious illness, cancer, heart attack, and stroke account for most claims, and the client has to survive a defined period after diagnosis (commonly 14 days) for the claim to be valid. Income protection works differently: it replaces a portion of income each month for as long as the client is unable to work due to illness or injury, after a deferred period the client chooses, typically 4, 8, 13, 26 or 52 weeks, until they return to work, the policy ends, or they retire. The deferred period is worth getting right at the point of sale: set it too short and the client pays more than they need to for cover that duplicates existing sick pay; set it too long and there's a gap between the sick pay running out and the policy starting to pay.
The ABI's 2025 claims figures show just how differently the two products behave in practice. Critical illness insurers paid out £1.25 billion in 2025, an average claim of £67,000, with cancer accounting for 65% of claims. Income protection paid out £209 million, a record high, at an average claim of £10,700, and mental health conditions made up 19% of claims. Critical illness is doing a small number of large, one-off payouts. Income protection is doing a larger number of smaller, ongoing ones. That difference in shape is exactly why the two products aren't interchangeable.
Before recommending either product, it's worth establishing what a client would fall back on if they couldn't work. An employer sick pay scheme, where one exists, is usually the first line of defence, but coverage and duration vary hugely between employers and often run out well before a serious illness resolves.
Where there's no occupational scheme, statutory sick pay is what's left, and it changed significantly from 6 April 2026. The lower earnings limit was scrapped, so every employee qualifies regardless of income, and the three-day waiting period was abolished, so SSP is now payable from the first full day of sickness. But the rate itself didn't become more generous: it's the lower of £123.25 a week or 80% of average weekly earnings, capped at a maximum of 28 weeks in any one period of sickness. For a client with a mortgage, that's rarely close to enough. Self-employed clients have nothing at all in this category, no sick pay of any kind, which is usually the single clearest signal that income protection deserves priority in the conversation.
Income protection policies define incapacity in different ways, and the definition matters more for some clients than others. An "own occupation" definition pays out if the client can't do their specific job, even if they could technically do a different one. An "any occupation" definition, generally cheaper, only pays if the client can't do any job suited to their skills and experience. Take a self-employed plasterer with a shoulder injury: under an own occupation definition, unable to plaster is unable to work, and the claim stands. Under an any occupation definition, an insurer could reasonably argue there's other work they're capable of, and decline it. For a client whose income depends on a specific, narrow skill set, a specialist tradesperson, a self-employed professional in a niche field, the gap between those two definitions can be the difference between a policy that pays out and one that doesn't when it matters.
This is often the clearest way to separate the two products in a client conversation. If the concern is replacing income so ongoing bills and the mortgage keep getting paid while someone recovers, that's an income protection problem. If the concern is a lump sum, clearing the mortgage outright on a serious diagnosis, funding treatment or adaptations, covering a period where the whole household's plans change at once, that's a critical illness problem.
Two clients with similar mortgages can land in very different places here. A client who says their priority is "just keep the household running if I can't work for a while" is describing income protection, almost word for word. A client who says "if I ever got a cancer diagnosis, I'd want the mortgage gone so I'm not worrying about payments on top of everything else" is describing critical illness cover just as precisely. Neither client necessarily knows the product names, but the conversation about what they actually want to happen usually points to one or the other on its own. Some clients need both, layered rather than duplicated, because they cover different failure modes: one continues paying out for as long as the client can't work, the other pays once and is done.
Pure protection contracts are advised under ICOBS, not MCOB. ICOBS 5.3.1R requires a firm to take reasonable care to ensure the suitability of its advice, and ICOBS 5.3.2G sets out what that means in practice for a pure protection sale: establishing the customer's demands and needs, including existing cover, checking the recommended contract matches those needs on cover level, cost, and exclusions, and telling the customer about anything that's still unmet. Where a personal recommendation is made, ICOBS 5.3.4R goes further and requires a personalised explanation of why that particular contract best meets the customer's demands and needs.
In practice, that means the file needs to show which of the factors above applied, sick pay position, occupation, what the payout was meant to cover, not just that "protection was discussed" and a product was sold. It's the same discipline this site has covered for when a client declines protection outright, applied to the other end of the conversation: the reasoning has to survive being read back months or years later, the same standard Consumer Duty case records are held to more broadly, not just at the point of sale.
Cleera keeps this evidence attached to the case instead of left in a separate note. Protection cases run on their own pipeline and fact-find, linked to the same client record as any mortgage case, so the demands-and-needs detail sits right next to the recommendation itself. Commission, ERC schedule, sum assured, and placement status all live on the case too, and a firm can track protection as a share of total business on the dashboard rather than guessing at it at year end. Get in touch if you want to see what that looks like against your own protection pipeline.
Can a client have both income protection and critical illness cover? Yes, and it's common where budget allows. They trigger on different events and pay out differently, so having both isn't redundant, income protection replaces ongoing income during incapacity, critical illness pays a lump sum on a specified diagnosis.
Is critical illness cover cheaper than income protection? It varies by client, but critical illness cover is often cheaper for a younger, healthier client because it pays once on a defined event, while income protection can pay out repeatedly over a longer period and is priced accordingly. Get an actual quote rather than assuming, since occupation and health both move the price significantly.
Does a client need critical illness cover if they already have life insurance? They're not a substitute for each other. Life insurance pays on death; critical illness cover pays on diagnosis of a specified serious illness while the client is still alive, when costs and pressure on income often start well before any question of life cover being needed.
What if a client has no sick pay at all? That's the client with the clearest case for income protection. Self-employed clients and anyone without an employer sick pay scheme have nothing beyond statutory sick pay, and even that is capped at 28 weeks and pays a flat £123.25 a week or 80% of average earnings if lower, nowhere near enough to cover a mortgage for most people.
