Charging an EV in Guernsey and the Channel Islands

Charging in the Channel Islands works differently from the UK mainland. Guernsey and Jersey are Crown Dependencies, not part of the UK. That means UK schemes such as the Ofgem price cap (which covers England, Scotland and Wales) and the OZEV chargepoint grants are not the rules here. Each island has its own electricity company and its own public charging setup. Everything below comes from the official websites of Guernsey Electricity, the States of Guernsey, Plug-N-Go and Jersey Electricity, all checked on 3 October 2026. Where we could not confirm something, we say so.

Guernsey: home charging tariffs

Guernsey Electricity publishes its domestic tariffs online. These prices are effective from 1 July 2026, after the States Trading Supervisory Board approved a 5% revenue increase.

Super Economy 12 (E12) is the tariff that matters for EV drivers. It gives you 12 low-rate hours a day: a 10-hour period somewhere between 19:45 and 08:15, and a 2-hour period somewhere between 12:00 and 16:40. Your exact times are assigned to the property, not to you, so they can change if you move. Check your meter or bill, or ask Guernsey Electricity. Connections are for a minimum of 12 months, and you may need extra space at the meter position for the equipment.

Guernsey Electricity recommends charging EVs between 11pm and 5am where possible. It says this is when the island can rely on 100% low-carbon electricity imported from the European grid, so the power station is not needed overnight. It also says that if you move more than 10% of your usage into low-rate times, E12 starts to save you money compared with the Standard tariff.

What that means in pounds

Here is an example. Say you drive 5,000 miles a year at 3.5 miles per kWh. That is about 1,430 kWh, plus a little extra for charging losses.

• On the E12 low rate (13.12p): about £187 a year.
• On the Standard rate (26.01p): about £372 a year.
• On public chargers at 45p–79p (see below): about £640–£1,130 a year.

Guernsey: installing a home charger

Guernsey Electricity asks you to tell it about any EV charger installed at your property:

• Up to 3.6 kW: just register the charger. Guernsey Electricity says most homes only need a charger up to this size.
• Faster chargers: you need to apply for additional load first, so it can check that the cable supplying your property has enough capacity.

For scale: a 3.6 kW charger running through a full 10-hour low-rate window could deliver up to about 36 kWh. At 3.5 mi/kWh that is enough for well over 100 miles, which covers a lot of island driving.

Guernsey: public charging

The States of Guernsey owns four public charging sites: North Beach, Salerie and Odeon car parks in St Peter Port, and La Crocq Pier in St Sampson. Guernsey Electricity says each site has two 7.2 kW charging units.

• How to pay: start a session with the Plug-N-Go app, or with a key fob ordered through the app. The States' page says credit and debit cards currently cannot be used to start a session. If you do not have a smartphone, you can call the support line shown on the signs. Plug-N-Go's general pricing page lists contactless as an option, so check the charger itself.
• Price: Plug-N-Go's Guernsey pricing page says each site sets its own price, between 45p and 79p per kWh depending on location and speed. The price is shown in the app and on the charger before you start. There are no session or membership fees.
• Time limit: parking at the States' sites is limited to 3 hours, and normal disc parking rules apply, so display your parking clock.
• Other chargers: some hotels and businesses offer charging. The States suggests Zap-Map to find them.

Not verified: we could not confirm from official sources whether Guernsey has any public rapid (DC) chargers. Check Zap-Map or the Plug-N-Go app for the current list.

Jersey: the Evolve network

Jersey Electricity runs the Evolve public network. Its charger types are 7 kW, 22 kW, 50 kW and 150 kW. The published tariffs for registered users, which include GST, are:

• Guest, one-time and contactless payments cost 10% more. Contactless card payment is available on the rapid and ultra-rapid chargers.
• On rapid chargers, a £5 overstay fee applies if a session runs longer than 2 hours.
• Parking fees are separate from charging costs.
• For home charging, Jersey Electricity offers "Easycharge" charger-and-plan subscriptions from £30 a month (minimum 3 years, fair-use policy applies). It also says its off-peak EV times are 00:00–06:59. We did not confirm Jersey's domestic unit rates for this guide, so check jec.co.uk for current prices.

Alderney, Sark and Herm

We could not find official, current information on public EV charging or EV electricity tariffs for Alderney, Sark or Herm, so we are not giving any figures. If you live in or are visiting these islands, ask the local electricity supplier and check Zap-Map or PlugShare.

Tips for Channel Islands EV drivers

• Charge off-peak. Guernsey's E12 low rate is less than half its normal rate. Jersey's Evolve off-peak public rate is half the peak rate.
• Size the charger to your needs. In Guernsey, a charger up to 3.6 kW avoids the additional-load application and may be all you need for local mileage.
• Leaving the island? UK prices and networks are very different. See our public charging reality check and road trip charging guide.
• Winter still matters, even on short trips. See EV winter range.
