Sockets in Sri Lanka
In Sri Lanka, you’ll find Type D and G plugs and sockets.
Type D

Type D sockets have three large round pins in a triangular shape. Unlike Type G, they lack a fuse and the pins are round rather than rectangular.
Type G

Type G sockets have three rectangular pins arranged in a triangular pattern, with a built-in fuse for safety. They are the standard used in the United Kingdom.

Realised abroad that you’ve left your adaptor behind? You’ll often find them in airports and shops nearby. Still, carrying your own is cheaper and more reliable.
Sri Lanka is often combined with trips to India and the Maldives. It’s smart to double-check plug types — even nearby destinations can use different systems.
Do You Need a Voltage Converter?
In Sri Lanka there’s no call for a converter, as the voltage is near enough to the UK standard.
Before you plug in abroad, make sure to check the voltage label. Devices marked ‘100–240 V, 50/60 Hz’ can handle different voltages, so no converter needed.
