About electricity in United Kingdom
The United Kingdom uses 230V/50Hz with Type G sockets: the fused, shuttered, three-rectangular-pin British plug.
Grid & history
The UK standardised on 230V after WWII and now runs one of Europe’s lowest-carbon major grids. Offshore wind is the largest single source, with nuclear, gas, and rooftop solar making up most of the rest.
Availability
Reliability is excellent nationwide.
Sockets & hotels
Type G is universal across England, Scotland, Wales, and Northern Ireland. Every plug carries its own fuse, and the sockets have internal shutters that only open when the earth pin enters first, which is a small but real safety advantage over most other plug systems.
Energy mix
Offshore wind is the largest single source.
Practical tips
- A Type G adapter is essential for any non-UK plug.
- Most hotels have universal bedside sockets that accept several plug types directly.
