Guernsey Power Plugs, Wall Sockets & Electrical Outlets
In Guernsey, power plugs and sockets (electrical outlets) of Type C (CEE 7/16 (Europlug), two round pins, ungrounded) and Type G (BS 1363, three rectangular pins in triangular pattern, grounded) are used. Wall sockets run at 230V and 50Hz. Check if you need a travel adapter, electrical adapter or voltage converter before travelling to Guernsey.

Electrical Standards in Guernsey: Voltage, Frequency & Plug Type
Guernsey runs on the same electrical standard as the United Kingdom, supplying power at 230V and 50Hz to homes, hotels, and businesses across the island. The Guernsey power plug in use is the Type G (BS 1363), a three-pin design recognized for its robust safety features and widespread use throughout British territories. Visitors arriving with appliances designed for other voltage systems or plug shapes should check compatibility before plugging into any wall socket.
Voltage and Frequency in Guernsey
Electricity in Guernsey is delivered at 230 volts and 50Hz, consistent with the wider European and UK electrical framework. This standard voltage and frequency supports everyday household appliances, chargers, and electronics without alteration. Travelers from regions using significantly different voltage systems may still need a converter for certain high-power devices, though most modern electronics tolerate this range automatically.
Do All Sockets in Guernsey Look the Same?
Most sockets on the island follow the Type G standard, featuring three rectangular pins arranged in a triangular pattern with a longer earth pin at the top. However, smaller ungrounded devices such as phone chargers often use a Type C Europlug, which fits into Type G outlets with the help of a simple travel adaptor. This means visitors typically only need one type of adaptor to cover the vast majority of their charging needs.
Understanding Guernsey's Power Plugs and Sockets
The Type G plug top is built for durability and safety, with rectangular pins sized at 6.35x3.18mm for live and neutral, and a slightly larger 3.18x7.92mm earth pin. Each plug contains an internal cartridge fuse, rated at either 3A or 13A depending on the appliance, which provides individual protection against overcurrent. The design also ensures the earth connection makes contact first and disconnects last, a safety feature that has made this plug style a global benchmark.
- Type G: Grounded, 13A, 220-240V, used for most UK-style appliances
- Type C (Europlug): Ungrounded, 2.5A, 220-240V, used for small electronics like phone chargers
- Standard voltage in Guernsey: 230V at 50Hz
Because Type C Europlugs are compatible with Type G sockets when paired with an adaptor, most travel electronics can be used with minimal fuss. High-power devices, however, should always use a genuine Type G plug top rather than relying on a Europlug adaptor, since the Europlug is rated only for low-power devices up to 2.5 amps.
Frequently Asked Questions
If your home country uses Type G plugs, no adapter is needed since Guernsey uses the same BS 1363 standard. Travelers from countries using other plug types will need a travel adaptor to fit local Type G sockets, and small devices with Type C Europlugs will also require an adaptor to connect safely.
Yes, the standard Type G sockets used throughout Guernsey are grounded, with a dedicated earth pin that connects before the live and neutral pins. This grounding, combined with an internal fuse in each plug, makes the system particularly safe for high-power appliances.
Most phone chargers are designed to handle a range of voltages, including Guernsey's standard 230V at 50Hz, so a voltage converter typically isn't necessary. You will, however, need the correct plug shape—either a Type G plug or a Type C Europlug with an adaptor—to physically connect to a wall socket.
Guernsey uses the Type G plug (BS 1363), the same three-pin, grounded standard used in the United Kingdom. Smaller ungrounded devices sometimes use a Type C Europlug, which can be connected via an adaptor for compatibility with local sockets.
