If you have any old paper £10 notes, you should think about getting rid of them as soon as possible...
After the introduction of the new polymer £10 bank note, the deadline was set for when the old £10 note would be phased out. After midnight on March 1st, shops and businesses will no longer accept the paper note, and the only way you will be able to use them is if you exchange them at the Bank of England.
What To Do With Old £10 Notes
Some retailers and banks may still accept the £10 note, as happened with the old £1 coin after the October 15th deadline passed, however it is important to remember they have no obligation to. If you do have a number of the old £10 notes, it is advisable to take them to your bank to exchange them ahead of March 1st. If you are unable to do so, you may need to personally take them to the Bank of England in London, or arrange an exchange via post.
Full details on how to exchange your old notes can be found on the Bank of England website.
