About

Who is Jersey Electricity?

Registered as Jersey Electricity plc, Jersey Electricity uses this legal name for Ofgem licence filings, contracts and any formal communications. The trading name customers see on bills is the shorter, more recognisable form.

The company is headquartered in St. Helier, Jersey, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

Jersey Electricity was established in 1924. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

Jersey Electricity operates independently — it is not part of a larger corporate group. This typically means faster decision-making but less wholesale-market scale.

As a Northern Ireland energy supplier, Jersey Electricity is regulated by the Utility Regulator (UR) for Northern Ireland, not Ofgem. Statutory consumer protection is handled by the Consumer Council for Northern Ireland (CCNI), which escalates unresolved complaints on behalf of NI households.

Who owns JEC?

CEO: Chris Ambler (CEO)
Ownership: Partially — the States of Jersey hold about 62% of the share capital
Listed: Yes (London Stock Exchange, ticker: JEL)
Holders: States of Jersey (approx. 62% of issued share capital); the remaining shares trade publicly on the London Stock Exchange Main Market (LON: JEL). Jersey Electricity has been listed since 1962.

Fuel mix

Jersey Electricity electricity fuel mix (2024)

Jersey Electricity imports about 95% of its supply from France via the Channel Islands Electricity Grid (CIEG) subsea cables. The imported energy is sourced from the French generation mix, roughly 60% nuclear, 32% renewable (mostly hydro and wind) and the balance gas. The remaining 5% is local generation at the La Collette oil-fired station (held mainly as back-up) plus a small contribution from Jersey rooftop solar microgeneration. Carbon intensity averages 28-35 g CO2/kWh, about one tenth of the UK grid average.

Renewable 32%
Nuclear 60%
Natural gas 3%
Coal 0%

Network coverage

Where Jersey Electricity supplies energy

Jersey Electricity operates on 2 distinct distribution networks. Each network has its own pricing, regulatory rules and competing suppliers, check which one covers your postcode before comparing tariffs.

Network

Bailiwick of Jersey — electricity supply

Sole licensed electricity supplier (de facto monopoly)

Connections: About 50,000 households and 5,000+ businesses
Mains: Approx. 1,200 km of high-voltage and low-voltage distribution network on Jersey
Investment: Capital programme of about £20 million per year on the local network (renewals, smart-grid upgrades)

Main towns & areas

St. Helier (capital)
St. Saviour
St. Clement
Grouville
St. Martin
Trinity
St. John
St. Mary
St. Ouen
St. Peter
St. Brelade
St. Lawrence

Good to know: JEC is the only company licensed to sell electricity in Jersey under the Electricity (Jersey) Law 1937, there is no retail competition on the island. The Jersey Competition Regulatory Authority (JCRA) reviews tariff changes each year before they take effect.

Network

Channel Islands Electricity Grid (CIEG)

Wholesale subsea-cable joint venture with Guernsey Electricity

Connections: 3 active subsea HVAC cables (Normandie 1, 2 and 3) plus the Jersey-Guernsey interconnector
Mains: Normandie 3 (commissioned 2024): about 32 km of new 90 kV cable from France to Jersey, lifting island import capacity to 200 MW.
Investment: Normandie 3 alone: capital cost about £60 million, jointly funded by JEC and Guernsey Electricity.

Main towns & areas

France-Jersey link: La Tournelle (Normandy) to La Collette (St. Helier)
Jersey-Guernsey link: La Moye (Jersey) to Vale (Guernsey)

Good to know: CIEG Ltd, equally owned by JEC and Guernsey Electricity, operates the subsea infrastructure that imports French low-carbon electricity to both islands. The Normandie 3 cable, energised in October 2024, replaced the EDF1 cable from 1985 (now decommissioned) and restored full N-1 redundancy after the 2012 Normandie 1 anchor incident.

Current tariffs

Jersey Electricity tariffs: as of 1 April 2026

Jersey is a Crown Dependency and is therefore not subject to the GB Energy Price Cap. Instead, JEC publishes a single tariff schedule each year, effective 1 April, which is reviewed by the Jersey Competition Regulatory Authority (JCRA) before taking effect. All unit rates below exclude Jersey GST (5%). There are no exit fees on JEC domestic tariffs, you can switch between tariffs free of charge once a year per meter (additional changes incur a £33 administration fee). JEC supplies electricity only; for gas see Jersey Gas.

Common questions

Jersey Electricity — frequently asked questions

Jersey Electricity is regulated by Ofgem and operates under a standard domestic-supply licence. Whether it is the right supplier for your household depends on your unit rate, standing charge, customer-service rating and any add-on services (HomeCare, Warm Home Discount eligibility). Always quote your annual kWh consumption when comparing prices — the headline rate alone does not predict your bill.

Switching to Jersey Electricity takes about five working days under the new Faster Switching service, and your supply is never interrupted. Sign up online with your address, postcode and a recent meter reading. Jersey Electricity will arrange the transfer with your current supplier, including the final meter reading and the closing bill.

The UK grid is supplied by a mix of gas, nuclear, wind, solar, biomass and imports. Jersey Electricity declares its fuel mix annually under Ofgem rules — see the fuel-mix section above for the current figures. Some tariffs are sold as 'green' or '100% renewable', which means the supplier matches your annual consumption with renewable electricity certificates (REGOs) rather than physically delivering renewable electrons to your home.

Most UK fixed-term tariffs include an exit fee (typically £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. Variable tariffs (including the default tariff capped by the Energy Price Cap) have no exit fees.

You can reach Jersey Electricity on 01534 505460, Mon-Fri, 8 a.m. to 6 p.m.. For a full breakdown of phone lines (emergency, prepayment, HomeCare, bereavement, Welsh, Relay UK), see the Jersey Electricity contact page.
