The currency in Jersey is British pound (GBP)

Before you head off on your holiday to Jersey, rest assured that the currency is the same as the UK. This means you don’t have to worry about changing any money over. Jersey also has its own currency (Jersey Pound), which you may be given as change. This isn’t deemed legal tender in the UK, but if you visit your bank they should give you the equivalent in Sterling.

You can also withdraw cash from an ATM, but most machines will dispense the local currency. Just like the UK, debit and credit cards are widely accepted too, and can be used freely without any charges.
