London uses Type G outlets with 230V/50Hz power, so US travelers need a UK plug adapter.

Dead phone batteries in London usually come from one small packing miss: the plug shape is not the same as the US or mainland Europe. What Outlets Does London Use? London uses the UK’s Type G socket, the three-rectangular-pin outlet found across England, Scotland, Wales, and Northern Ireland.
For most US travelers, the answer is simple: pack a Type G plug adapter. A plug adapter changes the shape of the plug; it does not lower London’s 230V electricity to the US 120V level. Phones, laptops, cameras, tablets, and USB chargers usually work because their power bricks often say “Input: 100–240V.” Hair dryers, curling irons, older electric shavers, and some travel kettles are the devices that can cause trouble.
London Outlet Type And Voltage: What To Pack
London uses Type G sockets, 230 volts, and 50 hertz. A US two-flat-pin or three-prong plug will not fit a London wall socket without a Type G adapter.
The Type G plug has three rectangular pins in a triangular layout. The top pin is the earth pin, and UK plugs are commonly fused, which is one reason the plug is bulkier than a US Type A or Type B plug.
Pack these items before flying to London:
- A Type G adapter for each charger you plan to plug into the wall.
- A USB-C or USB-A multi-port charger labeled “100–240V.”
- A power bank for long museum days, train rides, and map use.
- A voltage converter only for single-voltage 120V appliances that you truly need.
Do US Plugs Work In London?
US plugs do not fit directly into London outlets. US electronics work in London only when the device can handle 230V and you add a Type G adapter.
Check the tiny label on the charger or appliance before packing it. A safe modern charger usually says “Input: 100–240V, 50/60Hz.” That means the charger can accept both US and UK voltage, so the adapter only changes the plug shape.
A device labeled “120V only” is different. A plug adapter will not protect it from London’s higher voltage. Single-voltage hair tools are the common failure point, so travelers are usually better off using a hotel hair dryer or buying a dual-voltage travel model before the trip.
| Device Or Item | Will It Work In London? | What To Bring |
|---|---|---|
| iPhone or Android charger | Usually yes, if labeled 100–240V | Type G adapter or UK USB charger |
| Laptop charger | Usually yes, if labeled 100–240V | Type G adapter |
| Camera battery charger | Usually yes, but check the label | Type G adapter |
| Apple Watch or smartwatch charger | Usually yes through a USB charger | USB charger plus Type G adapter |
| US hair dryer | No, if labeled 120V only | Dual-voltage model or voltage converter |
| Curling iron or straightener | Only if dual-voltage | Dual-voltage tool plus Type G adapter |
| Electric toothbrush charger | Varies by model | Check for 100–240V before packing |
| CPAP machine | Often yes, but confirm the power brick | Type G adapter and medical-device backup plan |
What Is The Difference Between An Adapter And A Converter?
A plug adapter changes the plug shape so your charger fits the wall socket. A voltage converter changes the electrical voltage for devices that cannot accept London’s 230V supply.
Most travelers only need the plug adapter. London’s outlet shape is the barrier for modern electronics, not the voltage, because phone and laptop chargers are normally made for global voltage ranges.
Hair tools deserve a stricter check. A single-voltage 120V hair dryer can overheat or fail when plugged into 230V power through a basic adapter. A voltage converter must also be rated for the appliance wattage, which makes travel-size dual-voltage tools the easier option for most trips.
The safest rule is printed on the device label, not on the adapter box. Electrical Safety First lists the United Kingdom as using Type G plugs, a 230V supply voltage, and a 50Hz frequency on its United Kingdom travel adaptor page.
London Power Sockets In Hotels, Cafes, And Trains
London hotels normally have Type G wall sockets, and newer rooms may add USB-A or USB-C ports near the bed. Cafes and trains vary, so a compact adapter still matters even when your hotel room is well equipped.
Hotel bathrooms can be misleading. Some bathrooms have a low-power shaver socket marked for shavers only, not a normal outlet for hair tools or chargers. Use the main room socket for regular charging unless the hotel’s own markings say otherwise.
On trains from London, long-distance services often have sockets or USB ports, but the exact setup depends on the train operator and carriage. The London Underground is not a place to rely on outlet access, so charge before long Tube-heavy days.
Where To Stay In London If Charging Access Matters
Central London is the easiest base if you want short travel days, frequent hotel returns, and quick access to charging between plans. Westminster, Covent Garden, South Bank, and King’s Cross are practical areas for first-time visitors who use phones heavily for maps and tickets.
Apartment-style stays can be useful for families carrying several devices, but older buildings may have fewer sockets than newer hotels. A small multi-port USB charger solves that better than carrying four separate adapters.
After choosing your area, compare London hotels on a map so the room location matches your sightseeing route:
Can You Use European Adapters In London?
Most mainland European Type C or Type F adapters do not fit London Type G sockets. London uses the UK plug system, not the two-round-pin plug used in countries such as France, Italy, Spain, and Greece.
This matters on multi-country trips. A traveler flying from Paris to London may have the right adapter for France and still be unable to charge a phone in a London hotel room. A universal adapter with a UK setting is the simplest choice if your itinerary crosses several plug regions.
| Traveler Starting Point | Home Plug Type | London Packing Call |
|---|---|---|
| United States | Type A or Type B, 120V | Type G adapter; converter only for 120V-only appliances |
| Canada | Type A or Type B, 120V | Type G adapter; check hair tools carefully |
| Mainland Europe | Mostly Type C, E, or F, 230V | Plug-shape adapter for Type G |
| Australia | Type I, 230V | Plug-shape adapter for Type G |
| Singapore | Type G, 230V | No adapter for most standard plugs |
| Ireland | Type G, 230V | No adapter for most standard plugs |
| Japan | Type A or Type B, 100V | Type G adapter; voltage check for appliances |
Pack This For A London Trip
A US traveler should pack one Type G adapter, a dual-voltage USB charger, and a power bank for London. Add a voltage converter only when a device label says 120V and you still need that device.
For a simple London packing setup, use this list:
- Check every charger label for “100–240V.”
- Buy a Type G adapter or a universal adapter with a UK setting.
- Leave single-voltage 120V hair tools at home unless you have the right converter.
- Pack one multi-port USB charger instead of several wall bricks.
- Carry a charged power bank for airport transfers, Tube days, and mobile tickets.
Practical rule: if the device charges by USB and the wall charger says 100–240V, London usually requires only the Type G plug adapter.
London outlet planning is small, but it prevents an expensive airport purchase and a dead phone on day one. Bring the UK adapter, check the voltage label, and the rest of your London charging setup is easy.
