Frequently Asked Questions: United Kingdom
Do I need a plug adapter for United Kingdom?
The UK uses Type G plugs - the distinctive large three-prong design. You will absolutely need an adapter for any non-UK device. Type G outlets also have built-in switches - make sure to turn them on after plugging in.
Is tap water safe to drink in United Kingdom?
Yes, tap water in the UK is safe to drink and high quality. London water may taste different due to high mineral content but is perfectly safe. Restaurants provide tap water free on request.
Is travel insurance required for United Kingdom?
Travel insurance is recommended but not required. The NHS provides emergency care but non-emergency treatment and repatriation costs can be significant for visitors. EU citizens no longer have automatic EHIC coverage post-Brexit.
What currency is used in United Kingdom?
The UK uses the British Pound Sterling (£). Scotland and Northern Ireland issue their own banknotes that are legal throughout the UK, though some English shops may be unfamiliar with them. The UK did not adopt the Euro.
What voltage is used in United Kingdom?
The UK uses 230V at 50Hz. US and Canadian devices (120V) need a voltage converter for older appliances. Modern electronics like phones and laptops handle both voltages automatically - check your charger.
Do US devices work in United Kingdom?
US plugs will not fit UK outlets - a Type G adapter is essential. For voltage, most modern electronics auto-adjust from 100-240V. Hair dryers and other heat appliances typically need a converter, or buy one locally.
What is the emergency number in United Kingdom?
Emergency services: 999 (or 112). This connects to police, fire, ambulance, and coast guard. For non-emergencies, dial 101 for police or 111 for NHS medical advice.
What language is spoken in United Kingdom?
English is spoken throughout the UK, though regional accents vary significantly. Scottish, Welsh, and Northern Irish accents can take adjustment. Some Welsh and Scottish Gaelic signage exists in respective regions.
Do I need a visa for United Kingdom?
US, Canadian, Australian, and EU citizens can visit for up to 6 months without a visa. Post-Brexit, EU citizens no longer have unlimited stay rights. Passport checked at entry.
