Protection is optional and never a condition of your mortgage. There is no fee for protection advice. We are paid by commission from the insurer.

Take someone self-employed who is off work for four months after a back injury. They have paid buildings and contents insurance for twelve years without a second thought, and nothing at all towards the income that made the mortgage possible in the first place. The savings they had meant to leave untouched go on the mortgage instead. It is a hypothetical, but it is not an unusual shape.

For the self-employed, the gap is wider still — there is no statutory sick pay to fall back on, no employer scheme running quietly in the background, and no employer-funded group cover to cushion a period of incapacity.

This article is about income protection insurance UK mortgage holders should understand — not as a product, but as a concept worth thinking through honestly before something goes wrong.

What income protection actually does

Income protection insurance pays you a regular income if you are unable to work because of illness or injury. It is not a lump sum. It is not tied to a specific diagnosis the way critical illness cover is. It replaces a proportion of your earnings for as long as you remain unable to work — the exact percentage, duration, and terms vary by insurer, occupation, and individual underwriting, so any figure you see quoted elsewhere should be treated as illustrative rather than definitive.

That distinction from critical illness cover matters. Critical illness cover pays out on diagnosis of a condition named in the policy — cancer, heart attack, stroke, and others, depending on the insurer. If you are ill but your condition does not appear on the list, nothing is paid. Income protection, by contrast, responds to your functional ability to work, not to a diagnosis. A prolonged disc problem, severe anxiety, or an operation with a difficult recovery can all qualify — conditions that are common, disabling, and nowhere near dramatic enough to trigger a critical illness policy.

The two products are not interchangeable. Some people choose both. Others choose one based on their circumstances. The point is that they serve different purposes, and conflating them leads to gaps in cover that only become visible at the point of a claim.

The self-employed question

For income protection for self-employed people, the calculus is more urgent, and also more complex.

An employed person who falls ill may receive statutory sick pay — up to £123.25 a week, for up to 28 weeks (gov.uk, checked October 2026) — and some employers top this up considerably through group income protection schemes. A self-employed person receives neither. From day one of being unable to work, the income stops. The mortgage does not.

The question clients ask again and again — how much income protection do I need? — is simpler to answer than it first appears. Start with your committed monthly outgoings: mortgage, utilities, food, minimum debt repayments. That is your floor. Income protection does not aim to replicate your full lifestyle; it aims to keep the essential payments running until you can return to work or, if the condition is prolonged, until your policy term ends. The gap between your floor and your income is what you are insuring.

The other variable is the deferred period — the waiting period between being unable to work and the policy starting to pay. Shorter deferred periods mean higher premiums. If you have six months of accessible savings, a six-month deferred period brings the cost down meaningfully while still protecting you against a prolonged absence. If your savings are thin, a shorter deferral is worth the higher premium. This is a direct trade-off, not a rule, and the right answer varies by person.

Premiums are influenced by your age, health history, occupation, and the benefit level and term you choose. No premium figure I could set out here would be accurate for your circumstances — the range is wide, and an illustrative number without knowing your details would mislead more than it would inform.

What to think about before you act

Three things are worth sitting with before you pick up the phone to anyone.

First, check what you already have. Some employers provide group income protection that you may have overlooked in your benefits pack. Some professional bodies offer low-cost schemes for members. Start with what exists before layering new cost on top.

Second, understand the definition of incapacity your policy uses. This is a consequential decision, and it deserves more than a passing glance at the policy summary.

Policies that pay out if you cannot perform your own occupation are more generous than those that pay if you cannot perform any occupation. To make that concrete: a self-employed tiler who injures both hands may be physically incapable of returning to tiling, yet technically able to sit at a desk answering calls. An any-occupation policy could decline a claim on that basis; an own-occupation policy would not. The same logic applies to a physiotherapist, a surgeon, a joiner, or any professional whose work depends on specific physical or technical capability. For office-based workers, the distinction matters less acutely — but it still matters, particularly if your role requires a high degree of cognitive precision or involves specialist skills that a generic desk role would not replicate. Understanding which definition your policy uses before you buy — not after you claim — is essential.

Third, do not let perfect become the enemy of adequate. I have spoken with people who spent so long researching the optimal policy that they remained uninsured for years. A reasonable level of cover in place is worth more than a perfect policy perpetually under consideration.

Income protection insurance is not about pessimism. It is about recognising that your mortgage was underwritten on your income, and your income depends on your health. Protecting one without considering the other leaves a gap that is easy to miss until it matters.

This article is general information, not advice. The right level and type of cover depends on your circumstances, employment status and existing benefits. Policy terms and definitions differ between insurers and change over time.
