The British currency is pounds £ … don’t forget to let your banks know you will be travelling internationally.... Check with your credit card to make sure you have the lowest international fees - most of the city runs on 'tap to pay' so you won’t need a lot of cash necessarily

Tipping is only common in cabs and restaurants (if its not included in the bill 10% is standard, 15% max!), everywhere else do not tip...

Phones international plans /WIFI - almost every shop / store / restaurant has great WIFI in London… You may just need to get their password to log in

WhatsApp is a good app to use for international calling /texting if you don't have international plan as it works off WiFi



UK sockets have 3pins. If you are planning on bringing electrical appliances with you, you will need a US -UK plug adaptor. Worth noting that most UK hotels have hairdryers in the room
