Currency: The Isle of Man pound (IMP) is issued by the Manx government and has parity with sterling. Manx notes and coins are not accepted in the UK — exchange them before you leave the island. UK pounds are accepted everywhere on the island. Major credit and debit cards are widely accepted.
Language: English is the everyday language. Manx Gaelic (Manx) is an officially recognised language, taught in schools and undergoing active revival; you will see bilingual signs throughout the island. Fewer than 2,000 people are fluent speakers, but the language is no longer in danger of extinction after a near-complete collapse in the 20th century.
Mobile phones and internet: The Isle of Man has its own mobile network. UK SIM cards work but roaming charges may apply depending on your provider — check before you travel. Local SIM cards from Manx Telecom or Sure are available at the airport and in Douglas.
Time zone: Same as the UK — GMT in winter, BST (UTC+1) in summer.
Electricity: Same as the UK: 230V, 50Hz, Type G plugs.
Taxes: The island sets its own VAT rate (currently 20%, matching the UK). There is no inheritance tax and income tax rates are lower than in the UK — which is why the island has attracted a significant offshore finance sector. This has made the island prosperous but has also driven up property prices considerably.
The Fairy Bridge: On the main road south from Douglas, you pass the Fairy Bridge. Local tradition holds that you must greet the fairies as you cross, or bad luck will follow. Most Manx people do this without thinking; visitors are expected to play along. It costs nothing and is oddly satisfying.
