The new £50 featuring codebreaker Alan Turing enters circulation

A new £50 note featuring scientist Alan Turing has entered circulation for the first time  today, Wednesday, June 23

The new polymer note will start to become available in bank branches and at ATM’s in the coming days and weeks.

30 September 2022 will be the last day you can use Bank of England paper £20 and £50 notes. After 30 September 2022, these paper notes will no longer be legal tender, so we encourage people to spend them or deposit them at their bank ahead of this date.

The polymer £50 note contains advanced security features, completing our most secure set of Bank of England polymer banknotes yet.

The note will join the Churchill £5, the Austen £10 and the Turner £20, meaning all Bank of England banknotes are now available on polymer.

Speaking at Bletchley Park, where Turing carried out his famous codebreaking work, Governor Andrew Bailey said: “Our banknotes celebrate some of our country’s most important historical figures.”

“That’s why I am delighted that Alan Turing features on the new polymer £50 note.”

“Having undertaken remarkable codebreaking work here at Bletchley Park during the Second World War, he went on to pioneer work on early computers, as well as making some ground-breaking discoveries in the field of developmental biology. ”

“He was also gay and was treated appallingly as a result. Placing him on this new banknote is a recognition of his contributions to our society, and a celebration of his remarkable life.”

Speaking as the note entered circulation, the Bank of England’s Chief Cashier Sarah John said “The polymer £50 note is the most secure Bank of England banknote yet, and the features of the note make it very difficult to counterfeit.”

“All of our polymer banknotes can be checked by looking for two key security features: a hologram which changes image; and see-through windows.”

“So if you can check one denomination of banknote, you can check them all.”

“The new £50 notes, like the polymer £10 and £20 notes, contain a tactile feature to help vision impaired people identify the denomination.”

The Bank of England Museum has launched an online exhibition to coincide with the Turing £50 banknote entering circulation.

To celebrate Alan Turing’s life, the Bank of England is proudly flying the Progress Pride Flag above our Threadneedle Street building today.
