The note was introduced on 13 September 2016, with an initial print run of 440 million notes (worth £2.2 billion), over the period of co-circulation. It was announced that there would be a co-circulatory period with the old series E notes, and then on 5 May 2017, the series E would cease to be legal tender. However, as with all Bank of England notes, they can be exchanged at face value at any time in the future.
