Power Plugs in United Kingdom
The United Kingdom exclusively uses the distinctive Type G outlet - the three-pronged plug with built-in fuse that's considered one of the safest designs in the world. At 230V/50Hz, UK power matches most of Europe, but the unique plug shape means virtually all international travelers need a dedicated UK adapter. London hotels often provide adapters on request, but don't count on it.

Complete Guide to Power Plugs in United Kingdom
United Kingdom uses Type G power plugs and electrical outlets. The standard voltage is 230V with a frequency of 50Hz. This is significantly higher than the 120V used in the United States and Canada, so travelers from North America should check their device compatibility.
Do You Need a Travel Adapter for United Kingdom?
Yes, travelers from the United States, Canada, Mexico, and other countries using Type A/B plugs will need a travel adapter for United Kingdom. The Type G outlets used in United Kingdom are not compatible with American plugs.
Voltage Converter vs. Plug Adapter
It's important to understand the difference: a plug adapter only changes the physical shape of your plug to fit United Kingdom's outlets, while a voltage converter actually changes the electrical current. Since United Kingdom uses 230V (higher than US 120V), you may need a voltage converter for older appliances like hair dryers. However, most modern electronics (smartphones, laptops, cameras) have built-in converters that work with 100-240V.
Tips for Travelers to United Kingdom
- UK plugs have built-in fuses - if your adapter stops working, the fuse may need replacing (available at any hardware store)
- Bathroom outlets are the small two-pin 'shaver only' type at lower voltage - don't try to charge phones there
- Many UK hotels now offer USB ports built into bedside lamps or desks - check before unpacking adapters
- The Channel Tunnel means a different plug standard in France - bring both Type G and Type C/E adapters for combined trips
