The basic unit of UK currency is the Pound. Often known as GBP and expressed by the symbol '£'.

£1 = 100 pence. Coin denominations are 1p, 2p, 5p, 10p, 20p, 50p, £1 and £2.

Notes start off at £5, then £10, £20 and £50. The 'fiver' is the first of the notes to be issued in polymer form with the paper version gradually being withdrawn.
The larger denominations will follow suit. The foregoing applies to notes issued in England by the Bank of England.

Notes issued by Scottish and Northern Irish banks have different designs and £100 notes are also issued.
