Hundreds of millions of round pounds are yet to be handed in, as from midnight on the 15th October the round pound coin drops out of general circulation.
Although, major banks and building societies have said they will continue to accept the old coins after the deadline on Sunday.
They can also be deposited into any of the usual high street banks or through the Post Office.
Martin Kearsley, banking services director at the Post Office, said: “Thanks to an agreement with all UK high street banks, everyone can deposit old pound coins into their usual high street bank account at their local Post Office branch.”
Trade bodies say the industry has been working hard to update machines in time for the deadline. But there may be some cases where people find they are caught short.
The British Parking Association has said it is confident the majority of parking machines are ready or will be ready to accept the new £1 coin, while the Automatic Vending Association (AVA) said it believes all machines owned by its members are now accepting the new coin.
