One in five Britons have stumbled across savings they had forgotten they had, with some people finding a four or even five-figure sum.
Around 21 per cent said in a survey that they had found money they had forgotten about, with 6 per cent coming across an old children's savings account.
But an absent-minded 8 per cent admitted they had found forgotten savings in a deposit account, bond or ISA which they took out as an adult, according to Clydesdale and Yorkshire Banks.
About 1 per cent were reunited with more than 20,000 and the same proportion found 10,000 that they had forgotten they had.
Steve Reid, director of retail banking at Clydesdale and Yorkshire Banks, said: "Our research revealed that people are still keen to save this year and it's encouraging that people are putting money away for the future."
