A mortgage is the biggest financial commitment most people ever take on, and almost all of it rests on one quiet assumption: that your income keeps coming in, month after month, year after year. Most of the time it does. But life does not always read the script, and if your income stops, the mortgage does not pause to wait for it to come back.
This is not about scaring anyone. It is about closing a gap that a lot of people do not realise they have left open. And if you rent rather than own, do not skip this: your rent does not pause because your income does, so the very same gap applies to you.
Watch: could you still pay your rent or mortgage if you couldn't work?
Your mortgage is built on one assumption
When a lender works out what you can borrow, they are really asking one question: can this person keep paying every month for years to come? Your whole mortgage rests on the answer being yes. The trouble is that an illness, an injury or an accident can change that answer overnight, and it tends to happen when you least expect it. The bills do not shrink because you are unwell. The mortgage is usually the biggest of them, and the one with the most at stake if it goes unpaid.
This happens more often than people think
It is easy to assume missed mortgage payments are about overspending or poor budgeting. Often they are nothing of the sort. Research by MetLife UK gives a sense of how common it is for illness or injury alone to be the cause.
What the research found
More than a quarter of homeowners have already missed a mortgage payment because they got ill or had an accident, not because they were careless with money. For some it is not a one off either: around 1 in 14 have missed payments more than once after being unable to work. That is how quickly things snowball when the money coming in suddenly dries up, and it hits homeowners under 30 hardest, the ones who have stretched the furthest to get on the ladder and have the least slack if anything goes wrong.
"I have savings" is not the safety net it sounds like
Around seven in ten homeowners say they have savings to fall back on, which sounds reassuring. Dig into it, though, and those savings would last roughly six months on average, and for plenty of people a good deal less. One in five have nothing put by at all, so no buffer from day one.
So what happens when the savings run out? When homeowners were asked who they would turn to, the answers were telling:
- A third would turn to family.
- A quarter would lean on a partner.
- Only around one in six would rely on insurance.
- About one in seven would take on more debt to get by.
- And roughly one in ten said they have nobody to turn to at all.
Read that last one again. One in ten people would have no one to help if their income stopped, with a mortgage still due every month. That is a frightening place to be, and it is far more common than most of us would guess.
The "I thought I was covered" trap
This is the part worth real attention. The danger with protection is rarely that people decide against it. It is that they assume it is already handled.
Some homeowners only regret not having cover after they have already been through an illness or a loss of income. Others assume they are protected when they are not, and a fair few admit they only think about it once it is too late to do anything. By then the option has usually gone.
It is easy to believe you have it sorted, or that it will never happen to you, right up until the day it does.
What income protection actually does
Income protection is built for exactly this situation. If illness or injury stops you working, it pays out a regular, tax-free income to help keep the essentials going, your mortgage included, until you are well enough to return to work or the policy ends. Unlike life insurance or critical illness cover, which pay a lump sum for specific events, income protection replaces a slice of your earnings for as long as you need it.
Income protection does not start paying the moment you stop work. You choose a waiting period first, often anywhere from four weeks to six months, which usually lines up with however long your employer would keep paying you. The longer you can wait, the cheaper the cover. As with any policy, what you can claim for depends on the terms and the definition of incapacity, so it is worth understanding exactly what you are buying.
A few myths worth clearing up
- "My employer will cover me." For the 2026/27 tax year, statutory sick pay is £123.25 a week, about £534 a month, for up to 28 weeks. Some employers top it up, plenty do not, and on its own that is well below a typical mortgage of more than £1,000 a month.
- "The state will catch me." Benefits exist, but they are not designed to cover a typical mortgage and a household's outgoings on their own.
- "It is too expensive." The cost depends on your age, your job and the waiting period you choose, and it is often far less than people expect, especially when you are younger and healthy.
- "I will never need it." More than one in four homeowners have already missed a payment for exactly this reason. It is more likely than most of us care to admit.
Statutory sick pay is £123.25 a week for the 2026/27 tax year, roughly £534 a month, and it lasts up to 28 weeks. A typical mortgage on its own is now more than £1,000 a month, so sick pay would not even cover the home loan, let alone the food shop, the energy bill or anything else. For most households it is a long way short of keeping things afloat, which is the gap income protection is designed to fill.
Who should really think about it
If your household could not keep paying the mortgage or the rent for long without your income, this is worth a look. It matters most if you are:
- Self-employed. There is no employer sick pay at all, so the safety net is whatever you build yourself.
- A single-income household, or the main earner, where one income stopping puts the whole mortgage at risk.
- Light on savings, with less than a few months of outgoings put by.
- Carrying a large mortgage relative to your income, where there is little room to absorb a gap.
- Renting rather than buying. The rent still has to be paid if you cannot work, and renters often have a smaller savings buffer to fall back on.
What this actually means for you
None of this is meant to alarm you. A mortgage rests entirely on your income carrying on as normal, and the moment that income is at risk, so is the home. The point is not to sell anyone a policy. It is to have the conversation before you need it, rather than after. If you have a mortgage and have never really looked at what would happen if your income stopped, that is the gap worth closing, and it is usually a quick one to check. For the full detail, see our guide to income protection in the UK and how it fits alongside the rest of your protection. It is also worth knowing why modern income protection is generally far better value than the old mortgage payment protection insurance that earned such a bad name.
