The numbers also suggest that 68% of Brits are worried about money with 26% of people not feeling confident they can pay their bills every month.
The lender also found that 5.41 million households in the UK, more than a fifth, have no insurance protections in place, and 42% of people claim they cannot afford to take out cover.
Over a fifth (22%) of people do not think that home insurance is important, while 18% do not believe that they have anything worth insuring. Some 16% of people have never got round to taking insurances out and 15% don't have any because it is not a legal requirement.
Lee Mooney, head of home insurance at The Co-operative Insurance, said: "At the moment everyone is, understandably, looking to save money however a worryingly high percentage of population do not have home insurances and are leaving themselves open to much greater risks and expenditure in the long run.
"If there is a fire, originating from an uninsured home, which causes damage to other surrounding properties the uninsured person would be liable for repairs to all the damaged properties. Also if a policyholder decided to cancel their insurance and then an essential but expensive item was broken or stolen they could find themselves in a difficult situation, especially as the research shows that many people's outgoings are more than their incoming wage."
The new research comes as Co-operative Insurance and Shelter are joining forces to help raise money for the charity's vital work helping families across the country find and keep a decent home of their own. From today £5 will be donated to Shelter for every new Co-operative Insurance Home Insurance policy purchased.
The Co-operative Insurance is looking to raise £250,000 for Shelter through the partnership, with all the money raised going directly towards Shelter's vital housing advice service and free helpline, which helps thousands of people across the country keep a roof over their head.
Campbell Robb, chief executive of Shelter, added: "Nothing is more important than having the safety and security of a decent home. At Shelter we help people every day in desperate housing need and we are extremely grateful to Co-operative Financial Services for helping raise much needed money so we can help even more families during this difficult time.
"Through this partnership we hope that not only will people have the peace of mind that their own home is safe and secure, they can also make a huge difference to thousands of people in real housing need."
