The currency of Greece is the euro. When travelling outside the UK you should take more than one means of payment with you (cash, debit card, credit card).
Greece imposed capital controls on 28 June 2015 and there are still restrictions on some banking services in Greece. The Greek government continues to limit withdrawals using cards issued by Greek banks to €60 per day. However, these daily amounts can now be withdrawn cumulatively on a weekly basis.
You can withdraw cash using your UK card up to the daily limit imposed by the Greek banking system (usually €600), or the daily limit imposed by your card issuer - whichever is the lower amount. The system for paying with debit and credit cards for retail transactions continues to function.
There’s no guarantee that you’ll be able to exchange sterling for euros in Greece. There are no restrictions on taking unspent euros out of Greece at the end of your stay.
