Do you actually need an adapter for London?
One paragraph, no detour. Read this and you have 80% of what you need.
“London uses Type G outlets (three rectangular pins) with 230V electricity at 50Hz. The UK plug is one of the safest in the world, with built-in fuses and insulated pins. Travelers from the US, Europe, Australia, and Asia all need a Type G adapter. Your dual-voltage chargers (100-240V) work safely with just an adapter.”
What you'll actually find behind the bedside table.
How outlets vary across London's hotel categories — luxury, mid-range, hostels, and Airbnbs.
Most London hotels provide Type G outlets exclusively. Premier Inn, Travelodge, and budget chains have standard UK sockets. Higher-end hotels like The Savoy, Claridge's, and The Shard's Shangri-La sometimes offer universal outlet panels. Many newer hotels in King's Cross, Canary Wharf, and Southbank have USB-A and USB-C ports built into the headboard. Shaver sockets (small two-pin outlets labeled 'Shavers Only') are found in almost all UK hotel bathrooms and accept European two-pin plugs at lower power.
Where to buy an adapter on arrival.
Specific stores, transit landmarks, and price ranges in London — not generic "ask your hotel" advice.
Boots, WHSmith, and Argos on Oxford Street, Victoria Station, and Piccadilly Circus sell adapters for 5-12 GBP. Poundland and Primark in many locations carry basic US-to-UK adapters for 1-3 GBP. All London airports (Heathrow, Gatwick, Stansted, Luton) have WHSmith and Dixons Travel stores with adapters in arrivals and departures. London Paddington, King's Cross, and Waterloo stations also have convenience shops with adapters.
Why the wall matters more than the plug.
The plug shape decides whether it fits. The voltage decides whether it survives. Two different problems.
High-voltage region. Dual-voltage devices (rated 100–240V) work safely with just an adapter. Single-voltage 120V appliances from the US or Canada need a step-down converter.
Same frequency as Europe, Asia, and Australia. Modern electronics handle both 50Hz and 60Hz without issue.
Adapter ≠ converter.
A plug adapter only changes the shape of the prongs. It does not change the voltage. Always check the label on your device or charger for “INPUT: 100–240V” before plugging in.

Why is the UK plug so big?Open
The Type G plug was designed in the 1940s with safety as the top priority. Each plug contains a built-in fuse (typically 3A or 13A) that protects the device. The pins are partially insulated to prevent shock when partially inserted, and the socket has safety shutters that only open when the longer earth pin is inserted first. It is considered one of the safest plug designs in the world.
Can I use a shaver socket to charge my phone in a UK hotel?Open
Technically yes for some chargers, but it is not recommended. Shaver sockets in UK bathrooms are limited to low-wattage devices (usually under 200W). They accept two-pin European-style plugs. A phone charger may work, but it could charge slowly. The socket may trip or shut off with higher-draw devices. Use a proper Type G adapter at a standard outlet for reliable charging.
Do I need a different adapter for Scotland or Wales?Open
No. Scotland, Wales, Northern Ireland, and England all use the same Type G plug, 230V voltage, and 50Hz frequency. One UK adapter works everywhere in the United Kingdom.
