Banknotes carrying a portrait of King Charles III will be issued for the first time on 5 June 2024. The portrait of the King will appear on existing designs of all four banknotes (£5, £10, £20 and £50), with no other changes to the existing designs.
Polymer banknotes that feature the portrait of Her late Majesty Queen Elizabeth II will remain legal tender and will co-circulate alongside King Charles III notes. The new banknotes will only be printed to replace those that are worn, and to meet any overall increase in demand for banknotes.
The new notes can be checked using the same security features as existing HM Elizabeth II banknotes. More information on the specific designs and security features of these can be found at the following links:
Members of the public will also be able to exchange a limited value of current or old series notes for new King Charles III notes, through the Bank of England, for a short time from the 5 June 2024 issuance date.
