TheBank of England £20 note is asterling banknote. It is the second-highest denomination of banknote currently issued by theBank of England. The current polymer note, first issued on 5 June 2024, bears the image ofKing Charles III on the obverse. The other note first issued on 20 February 2020, bears the image of the lateQueen Elizabeth II on the obverse andthe image of painterJ. M. W. Turner on the reverse. It replaced the cotton paper note featuring a portrait of economistAdam Smith, first issued in 2007.^[1]

Twenty pound notes were introduced by theBank of England for the first time in 1725. The earliest notes were handwritten, and were issued to individuals as needed. These notes were written on one side only and bore the name of the payee, the date, and the signature of the issuing cashier. With the exception of the Restriction Period between 1797 and 1821 when theFrench Revolutionary Wars and theNapoleonic Wars caused a bullion shortage, these notes could be exchanged in full, or in part, for an equivalent amount of gold when presented at the bank. If redeemed in part, the banknote would be signed to indicate the amount that had been redeemed. From 1853 printed notes replaced handwritten notes, with the declaration "I promise to pay the bearer on demand the sum of twenty pounds" replacing the name of the payee. This declaration remains on Bank of England banknotes to this day. A printed signature of one of three cashiers appeared on the printed notes, though this was replaced by the signature of the Chief Cashier from 1870 onward.^[2]

The right to redeem banknotes for gold ceased in 1931 when Britain stopped using thegold standard.^[2] The twenty pound noteceased to be produced by the Bank of England in 1943, and it was not until 1970 with the introduction of the series D notes that the denomination reappeared. The predominantly purple series D notes were two-sided, with an image ofQueen Elizabeth II appearing on one side, accompanied by an image ofSaint George and the Dragon (all subsequent Bank of England notes also feature an image of the Queen) and an image ofWilliam Shakespeare appearing on the other. This note also had a security feature in the form of a "windowed" metal thread. The thread is woven into the paper so that it forms a dashed line, yet appears as a single line when held up to the light. Series D notes were phased out in favour of the newer series E notes beginning in 1991. These notes were multicoloured (predominantly mauve-purple) and featured an image of scientistMichael Faraday on the back. Series E notes were replaced by a variant design from 1999 onwards. These are broadly similar to the earlier series E notes but featureEdward Elgar on the reverse.^[3]

The most prevalent paper £20 note was introduced in 2007. It features a portrait of Scottish economistAdam Smith on the back as well as an illustration of workers in a pin factory.^[4] 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 underultraviolet light.^[5]

In September 2015 the Bank of England announced that the next £20 note would be printed on polymer, rather than cotton paper.^[6] This was followed by an announcement in April 2016 that Adam Smith would be replaced by artistJ. M. W. Turner on the next £20 note, which entered circulation on 20 February 2020.^[7][8] Images on the reverse of the Turner note include a c.1799 self-portrait of Turner, a version of Turner'sThe 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.^[9] Like all polymer banknotes issued by the Bank of England, the polymer £20 note features a transparent window to counteract forgery, and raised dots resemblingBraille to assist identification by the visually-impaired.
