Moving to Polymer Banknotes
The next Bank of England £5, £10 and £20 banknotes will be printed on polymer.
The new fiver will be issued in September 2016. On 2 June, the full details of the design and security features were revealed and a range of training materials for retailers and businesses have been made available. You can find out more about the new polymer £5 note at www.thenewfiver.co.uk
The £10 note will be issued in 2017 and the £20 note by 2020.
Polymer banknotes are cleaner, more secure, and more durable than paper banknotes. They will provide enhanced counterfeit resilience, and increase the quality of banknotes in circulation.
