Power Plugs & Voltage in United Kingdom
In United Kingdom, the standard voltage is 230V at 50Hz, and plug type G is used.
Your Type A / Type B plugs don't fit United Kingdom's Type G sockets. Pack a plug adapter.
United Kingdom runs much higher than home. A single-voltage 120V appliance can be damaged — you'd need a voltage converter. Dual-voltage devices (100–240V) are still fine.
Check your charger Most phone, laptop and camera chargers are dual-voltage (look for “INPUT: 100–240V” on the label). Those only ever need a plug adapter, never a voltage converter. High-wattage items with heating elements (hair dryers, straighteners, kettles) are the usual exception.United Kingdom mains: 230V, 50 Hz.
Note Type G plugs have a built-in fuse. The same plug is used across the UK, including Northern Ireland.

Many modern chargers, laptops, phones and cameras are dual-voltage: their label reads INPUT: 100–240V. Those work anywhere in the world with just a plug adapter — no voltage converter needed. Only single-voltage, high-wattage devices (hair dryers, travel kettles, straighteners) are a real concern in United Kingdom’s 230V supply. Always check the label on your own device.
