A new study has revealed that British holidaymakers came home with £1.75 billion in foreign currency this year.

The average person returns to Britain with £74 of currency from their holiday destination. The study, conducted by Santander, found that 72 percent of travelers bring Euro’s home, while 17 percent return with dollars.

Only 17 percent of travellers convert their foreign currency back into sterling, with most preferring to save the money for a future trip abroad.

Ian Coles, director at Santander Cards said: “We would always expect people to return home with some unused currency – but the amounts that people are bringing back to the UK are unnecessarily high, meaning there is an incredible amount of unused cash floating around the nation’s homes.”

Mr. Coles advised people to use the safer and more cost-effective mixture of cash and cards on their holidays.
