THE BANK OF ENGLAND is reminding people that paper £20 and £50 notes will cease to be legal tender after 30 September 2022.
“If you have any paper £20 or £50 notes, we encourage you to use them or deposit them with your bank or Post Office before 30 September 2022. As paper notes are returned to the Bank of England, they are being replaced with the new polymer £20 notes featuring JMW Turner, and polymer £50 notes featuring Alan Turing. After 30 September, only our polymer notes will have legal tender status.” – Bank of England.
