The findings also show that those in debt do not believe they have money worries until they have accumulated an average of £1,247 of debt in overdrafts, credit cards or loans.
The Co-operative Bank believes that those who are doing nothing to tackle their financial situation are suffering from the ‘DRIP syndrome' where people with debt either:
Deny that they have debt
Rationalise the reasons why they are in debt
Ignore that they have debt
Postpone putting their affairs in order
As a result, more than one in eight is turning to gambling and the lottery to get out of debt, while one in twenty people is in debt to payday lenders.
Around a fifth (22%) admits to being in debt for five years or more. And the research also shows that half the population has slipped into further debt in the past year, with the average debtor building up £325 in extra debt since Christmas alone.
Reasons for the debt pile up include the rising cost of living (28%), increased energy bills (28%) and rising fuel costs (16%).
Robin Taylor, head of banking at The Co-operative Bank, said: "It's no surprise that people are feeling the pinch at the moment and that debts are mounting up, but what is surprising is that many people are choosing to ignore their debt and are suffering from what we have identified as DRIP Syndrome.
"Our research also shows that the debt alarm doesn't go off until people owe more than £1,000, which can be a real struggle to pay back.
“Managing your money with steps such as writing a list of incomings and outgoings and regularly checking your bank account will help you get on top of your finances now before problems get any worse."
The findings also show that one in three surveyed say their debt has led to a feeling of ‘debtpression'.
Symptoms of ‘debtpression' include sleepless nights (60%), weight gain (25%) and anxiety attacks (30%).
As a result of this a fifth (22%) now don't feel able to make any sound financial decisions, whilst 12% of people have borrowed more money to try to alleviate their symptoms.
Kim Stephenson, finance and psychology expert said: "Unfortunately, ignoring debt, while a common reaction, is probably going to make the problem worse.
“Confronting the problems now will start you on the road to making your finances healthier and as a result, help you break out of the spiral of debtpression and alleviate many of the physical symptoms brought on by money worries."
