More than £1.5bn of outdated £5 and £10 notes not returned By Alun Jones BBC Wales Political Unit More than £1 5bn in old fivers and tenners has still not been cashed in more than a year after the last of them ceased to be legal tender  The Bank of England says 118 million paper £5 notes and 94 million £10 paper notes have still not been returned  The £5 notes were withdrawn in May 2017 and the £10 notes in March 2018, since when they have not been a legally accepted means of payment  They can still be exchanged at face value from the Bank of England. A bank spokeswoman said the number of £5 paper notes returned – more than 224 million – was lower than expected, while the number of £10 notes (697 million) was in line with expectations  She said the shortfall in returned fivers was likely to be because, as notes of relatively low value, they were more likely to be lost or damaged – together with a desire to retain them as souvenirs  While the paper £5 and £10 notes are no longer legal tender, they will always be accepted by the Bank of England  People can take or post any old notes to the bank in Threadneedle Street, in the City of London, to be exchanged for a new-style polymer one  The spokeswoman added: “All genuine Bank of England banknotes that have been withdrawn from circulation retain their face value for all time and can still be exchanged over the counter  “There is no fee for this service and there is no expiry on the period in which we will exchange old notes Banknotes can also be exchanged by post.”  The move to the new £10 and £5 notes – depicting author Jane Austen and Winston Churchill respectively – has been controversial  The Bank of England has persevered with the polymer material despite complaints from religious and vegan groups that it contains a small amount of tallow, which is derived from meat products  The demise of the paper notes follows the official withdrawal in October 2017 of the old circular £1 coin, which has been replaced by a 12-sided version
