The last date you can use your old £20 and £50 notes has been revealed.
There is still some time to exchange your old notes, but once the date has passed you won’t be able to.
From 2022, the paper notes will be fully replaced by new plastic ones.
You will have until September 30 next year to exchange or spend the notes until they will no longer be valid.
The new polymer notes are designed to last longer and are more environmentally friendly.
Based on the notes already used in other countries, the money will be able to survive being left in your pockets during a wash.
Already, the new £5 and £10 notes have been phased out for the new polymer ones.

The new £20 note will feature the face of artist JMW Turner.
He is famous for his colourful landscape paintings and the contemporary Turner art prize is named after him.
As for the new £50 note, this will feature codebreaker and mathematician Alan Turing.
During World War Two, Turing famously broke the Enigma code, helping allies to listen to German communications.
He was later chemically castrated for being gay, and was only pardoned in 2013.
The old notes will run out on September 30, 2022, from then you won’t be able to use them in stores.
But you do have options; you could either exchange them at the bank or the Post Office.
Alternatively you can post the notes to the Bank of England – or visit in person – where you’ll be sent the new polymer ones.
