Insurers and banks have come under attack for sending customers reams of unnecessary policy documents that are even longer than Macbeth.
Nearly three quarters of consumers admitted to not reading all of their policy documents or T&Cs because they were too long.
While only 17 per cent of people who did read it in full said they understood it, according to the survey of more than 2,000 people.
Consumer group Fairer Finance, who commissioned the survey, has launched a campaign against the book-length policy documents that are riddled with legalese and jargon.
Several terms and conditions sent out to customers were found to be nearly twice the length of Shakespeare’s Macbeth - which is 19,000 words long.
