Old £20 and £50 paper notes stopped being legal tender in the UK on 30 September 2022. This means you can’t use them in shops or as payment any more.

But, according to the Bank of England, there is around £6bn worth of £20 paper notes and over £8bn worth of paper £50 notes in circulation – that’s around 300 million individual £20 notes and 160 million £50 notes that haven’t been used before the notes were withdrawn from circulation.

Even though you can’t spend these old paper notes, it’s worth checking old bags, wallets and even the kids’ money boxes as you can still exchange old £20 and £50 notes.

New polymer plastic notes are replacing paper ones as they are stronger - they will even survive in the washing machine should you accidentally leave some cash in your pocket. They are also harder to counterfeit, helping the central Bank lock down on fraud.

But what should you do if you come across any old ones? We look at what to do with old £20 and £50 paper notes and where to exchange them for new polymer versions.

Exchange old £20 and £50 notes at The Bank of England

One option is to take the old paper notes down to the Central Bank in person.

There is currently no time limit when it comes to exchanging your old banknotes at the Bank of England. You may need an ID when exchanging notes.

In person: If you can and want to, you can swap your old notes at The Bank of England Counter, in Threadneedle Street, London. The counter is open between 9:30 am and 3 pm on weekdays. But do be aware, the Bank of England may have long queues and that after midday you may not be able to be served if it’s reached capacity.

By post: You can also post your old notes to the Bank, but note that this is done at your own risk and you may want to insure yourself against loss before sending banknotes in the post. You’ll also need to fill in a postal exchange form and send photocopies of your proof of ID and proof of address.

Go to your bank and exchange paper notes

Different banks have their own rules in place covering how they will handle paper banknotes ‒ while some are happy to exchange them for new polymer notes, others are not so understanding.

Banks that allow you to exchange paper notes will generally allow you to deposit the money into the account that you hold with them. Banks and building societies happy to exchange the old notes include Halifax, Lloyds, Nationwide, Barclays and HSBC - though keep in mind they may have a cut-off date.

In some cases you will be able to exchange the paper notes for the new polymer notes even if you do not have an account with that particular bank, for example with Bank of Scotland and Virgin Money.

How to exchange old paper £20 and £50 notes at the Post Office

You can deposit out-of-date banknotes – up to the value of £300 every two years – into your bank account at some local Post Offices. You will need to take photo ID so that the Post Office can keep track of how much you exchange and do not exceed the limit. You’ll be given the same value back in the new polymer notes.
