<P> The current £ 20 note was introduced in 2007 . It features a portrait of Scottish economist Adam Smith on the back as well as an illustration of workers in a pin factory . The note features a number of security features in addition to the metallic thread : these include raised print , a watermark , microlettering , a holographic strip , a see - through register , and a colourful pattern which only appears under ultraviolet light . In September 2015 the Bank of England announced that the next £ 20 note will be printed on polymer , rather than cotton paper . This was followed by an announcement in April 2016 that Adam Smith will be replaced by artist J.M.W. Turner on the next £ 20 note , which will enter circulation by 2020 . Images on the reverse of the Turner note will include a 1799 self - portrait of Turner , a version of Turner 's The Fighting Temeraire , the quote `` Light is therefore colour '' from an 1818 lecture by Turner , and a copy of Turner 's signature as made on his will . </P>
