Money and credit
Bank notes in the UK come in denominations (values) of £5, £10, £20 and £50. Northern Ireland and Scotland have their own bank notes which are valid everywhere in the UK, though sometimes people may not realise this and may not wish to accept them.
The euro
In January 2002 twelve European Union (EU) states adopted the euro as their common currency. The UK government decided not to adopt the euro at that time, and has said it will only do so if the British people vote for the euro in a referendum. The euro does circulate to some extent in Northern Ireland, particularly in the towns near the border with Ireland.
