Do I need an adapter from United Kingdom to Thailand?

Last reviewed · sourced from IEC TC 23 and national electricity standards

Your answer: United Kingdom → Thailand

Plug adapter
Adapter required

Thailand uses Type A, B, C, O; your United Kingdom plug (Type G) doesn't fit. Pack a Type A/B/C/O adapter — or a universal one if you travel often.

Voltage converter
Not needed

Both countries run on 230V at 50Hz. Your devices work as-is.

What this means for your trip

Going from United Kingdom to Thailand you'll need a plug adapter, but voltage is identical on both sides, so that's one less thing to worry about.

Thailand uses Type A/B/C/O outlets; United Kingdom uses Type G. The shapes are incompatible, so every plug you bring needs a Type A/B/C/O adapter to reach the socket. The cheapest option is a simple shape-only adapter for that one country; if you travel often, a universal adapter (fits every country) pays for itself in a single trip.

Voltage is the same on both ends (230V vs 230V, 50Hz vs 50Hz), so every charger that works at home works in Thailand without modification. No voltage converter, no hunting for "100-240V" on the brick.

Frequently asked

Do I need a travel adapter for Thailand from United Kingdom?
Yes. Thailand uses Type A/B/C/O outlets, which don't accept United Kingdom's Type G plugs. Pack a Type A/B/C/O adapter — or a universal one if you travel often.
What type of plug does Thailand use?
Thailand uses Type A and Type B and Type C and Type O outlets at 230V, 50Hz. Two flat parallel pins. Common in North America, Central America, and Japan.
What's the voltage in Thailand?
Thailand runs on 230V at 50Hz. That's on the high-voltage standard, matching than United Kingdom's 230V supply. Most modern phones, laptops, tablets, and camera chargers are dual-voltage (check for "100-240V" on the brick) and work on either. Single-voltage devices like hair dryers, curling irons, and travel kettles will not — bring a dual-voltage travel version or a voltage converter.
Are United Kingdom chargers dual-voltage?
Most — but not all. Check the charger brick for a line that reads something like "INPUT: 100-240V, 50/60Hz." If you see that, the charger works on either voltage standard and you only need a plug adapter. If it lists just "120V" (or just "230V"), it's single-voltage and can't be plugged straight into the other side without a voltage converter.
