And with more than half of Brits (52%) planning a summer getaway over the next two months, this means that as many as three million people without insurance will be leaving their homes empty for a week or more.
The research also reveals that despite this, many people still make careless mistakes when it comes to securing their home. One in five (20%) admit that they regularly leave windows open while more than one in 20 (6%) keep large amounts of cash in their home. In addition, 16% never lock their garden shed, 13% don’t know if their smoke alarm works and 5% leave a spare key under their door mat.
The findings also show that more than one in ten people (12%) have been caught out by not having insurance and have had to fund average losses of £358 from burglaries, house fires, spills and breaks out of their own pocket.
Lee Mooney, Head of Home Insurance at The Co-operative, said: "Worryingly, our findings show that a large number of people in the UK are going without home insurance, a problem which is particularly affecting the under 35s.
"The issue is that no one thinks they’re ever going to need insurance until something goes wrong, and in today’s economic climate it’s easy not to prioritise it. However, without it, you could be leaving your worldly goods open to damage or burglary and are risking paying out hundreds of pounds from your own pocket if something does happen."
The research shows that the economic climate is to blame for creating an "uninsured population" as the top reason for not having insurance is being strapped for cash, with more than half (56%) of those without home insurance saying they can’t afford it.
Nearly a quarter (24%) of those surveyed also say that they’ve stopped paying for home insurance as part of recent budget cut backs, while more than one in four people (26%) say that it features either "low" or "very low" on their list of "priority" household expenses.
The findings also show that the UK’s biggest uninsured population lives in London, with more than one in four adults (28%) taking the risk of not having insurance. The "safest" populations are Yorkshire and Northern Ireland, where nine in 10 people have home insurance.
It also shows that renters are happy to take more risks, as 40% per cent of those who live in rented accommodation forgo home insurance compared to just 7% of those who own their own home.
Statistics from The Co-operative Insurance also show that over a lifetime, more than eight in 10 people (85%) make at least one claim on their home insurance.
