Anyone with a £50 note should check now if it's an old edition, as you won't be able to spend it from 1 May.

The Bank of England is withdrawing all £50 notes featuring Sir John Houblon on 30 April.

First introduced in 1994, the Houblon note marked the 300th anniversary since Sir John founded the Bank. It's withdrawal means approximately 63 million £50 notes will be withdrawn, worth an estimated £3.2 billion.

Instead people can use a newer £50 note, which was introduced in 2011, and features pictures of entrepreneur Matthew Boulton and engineer James Watt.

This newer £50 note, which will be the only one in circulation from 30 April, includes greater security features, which makes it tougher for counterfeiters to fake.

Directly below is a picture of the Houblon note, which is being withdrawn. Underneath the Houblon note is the Boulton and Watt note that will be the only one in circulation from 30 April.

I've got a Houblon £50 note can I still use it?

Yes. You've got until 30 April to use the Houblon note, after this date you won't be able to spend it.

What if I don't want to spend my Houblon £50 note before 1 May?

If you don't want to spend your £50 note before 1 May, you can swap it in selected banks and building societies until the end of October 2014, though some will only accept deposits from their own customers.

From November onwards, the only way to ensure you don't lose your cash, is to post the note or visit the Bank of England in London where it will be swapped at face value.
