About

Who is Jersey Gas?

Registered as Jersey Gas Company Limited, Jersey Gas 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 Gas was established in 1831. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

Jersey Gas is part of the International Energy Group (IEG) — through subsidiary Channel Islands Gas Ltd; sister brands include Guernsey Gas and Manx Gas (Isle of Man) group, which provides shared governance, financial backing and a broader pool of expertise in trading, hedging and regulatory work.

As a Northern Ireland energy supplier, Jersey Gas 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 Jersey Gas?

CEO: Steve Pearce (Managing Director, Channel Islands Gas)
Ownership: Privately owned
Listed: No (parent IEG is privately held)
Parent: International Energy Group (IEG) — through subsidiary Channel Islands Gas Ltd; sister brands include Guernsey Gas and Manx Gas (Isle of Man)

Network coverage

Where Jersey Gas supplies energy

Jersey Gas 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 — mains propane

Sole licensed gas distributor and supplier (de facto monopoly)

Connections: About 16,000 mains-connected households and businesses
Mains: Approx. 250 km of medium- and low-pressure propane mains across St. Helier and the inner parishes
Investment: Annual mains-renewal programme; full digital pressure-monitoring rolled out 2022-2024

Main towns & areas

St. Helier (capital — densest mains coverage)
St. Saviour
St. Clement
Grouville (partial)
St. Lawrence (partial)
St. Brelade (partial)

Good to know: The Jersey Gas mains network distributes <strong>propane (LPG), not natural gas</strong>. Propane is shipped to the island and vaporised at the La Collette plant for mains distribution. Outside the mains footprint, Jersey Gas serves customers via bulk-tank or cylinder LPG (see the row below).

Network

Off-mains LPG (bulk tank + cylinder)

Bulk and cylinder LPG supplier for properties beyond the mains

Connections: About 3,000 bulk-tank and cylinder customers across the island
Investment: Tanker fleet renewal and digital tank-level monitoring trials in progress

Main towns & areas

St. Ouen
St. Mary
St. John
Trinity
St. Martin
St. Peter

Good to know: For homes in parishes without a mains connection, Jersey Gas supplies bulk LPG by tanker (refilled on schedule) or in 47 kg cylinders. Pricing is set per delivery and quoted by the sales team; bulk LPG is not unit-rated per kWh on the bill.

Current tariffs

Jersey Gas tariffs: as of 1 April 2026

Jersey is a Crown Dependency and is therefore not subject to the GB Energy Price Cap. Instead, Jersey Gas 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 Jersey Gas domestic tariffs. Mains-propane customers can switch between domestic tariffs once a year free of charge. Jersey Gas supplies gas only (propane LPG); for electricity see Jersey Electricity.

Timeline

Jersey Gas — key dates

A short timeline of the Jersey Gas brand — founding, milestones, regulatory events.

1831
The Jersey Gaslight Company is founded in St. Helier, one of the first public utilities in the Channel Islands. Coal-gas street lighting follows shortly after.
1850s
Mains gas lighting extends across central St. Helier; the company begins supplying domestic customers for cooking and lighting.
1900s
The mains network expands to the inner parishes; gas progressively replaces oil and coal for cooking in urban Jersey.
1960s
The company transitions from coal-derived town gas to imported LPG (propane) for mains distribution, cleaner, higher-calorific value and easier to ship to a small island.
1990s
Jersey Gas joins the International Energy Group (IEG) family, alongside sister utilities Guernsey Gas and Manx Gas (Isle of Man).
2010s
IEG ownership consolidates under Channel Islands Gas Ltd; mains-renewal and engineering investment increases.
2018
The Jersey Competition Regulatory Authority (JCRA) formalises its review of annual Jersey Gas tariff changes.
2021
Jersey Gas refreshes its three primary domestic tariffs, Super Economy 24 Central Heating, Super Economy 24 LPG, and Standard 24 Domestic.
2024
Digital mains pressure-monitoring rollout completes across the St. Helier propane network.
2026
New JCRA-approved tariff schedule takes effect on 1 April 2026; Super Economy 24 Central Heating remains the cheapest mains-propane CH tariff on the island.

Common questions

Jersey Gas — frequently asked questions

Jersey Gas 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 Gas 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 Gas 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 Gas 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.
