The main currency used in Egypt is the Egyptian Pound {EGP} however, the majority of tourists who come to Egypt use the EGP, GBP, or the USD and in order to get the best possible deal for exchanging your money, you need to wait until your arrival to Egypt and you can easily exchange your money at Cairo International Airport with the best exchange rate but if you decided to exchange your money in the UK, you will definitely lose lots of money change.
