Paper bank notes are being phased out and replaced, and Brits have just two more weeks to spend their old £20 and £50 notes.
The notes can be spent or deposited with your bank or post office on or before Friday 30 September. After that, they will no longer be legal tender and can't be spent.
The paper notes will be replaced by new polymer notes, the same material used for £5 and £10 notes. This is because it is more durable, even surviving a trip through the washing machine.

The new £20 note will feature prolific British painter JMW Turner, replacing economist Adam Smith, while the advanced £50 will feature mathematician Alan Turing. £5 notes were replaced in 2016, and £10 in 2017.
After 30 September, many UK banks will accept withdrawn notes as deposits from customers. Some Post Offices may also accept withdrawn notes as a deposit into any bank account you can access with them.
The Bank of England will always exchange any withdrawn notes, including paper notes we have withdrawn in the past. However, you will not be able to use these notes in shops or businesses after this date.
The new polymer notes are more difficult to counterfeit than paper notes, but it is still possible. All genuine notes have security features you can check for, including the foil over the window on a £5 note. You can check the foil is gold on the front of the note and silver on the back to confirm it is genuine.
