What Islands Energy Group does
Islands Energy Group Limited is a privately-held holding company headquartered in St Peter Port, Guernsey, owned by infrastructure-focused private equity firm Ancala Group. It is the sole provider of natural gas and liquefied petroleum gas (LPG) to domestic, commercial and industrial customers across three British Crown Dependency territories: Guernsey (Guernsey Energy), Jersey (Island Energy), and the Isle of Man (Isle of Man Energy), with Kosangas-branded LPG operations in Guernsey and Jersey. The group serves over 35,000 homes and businesses with a heritage dating back to the 1830s and approximately 180 employees across the three islands.
The group's core asset is its regulated gas distribution network infrastructure, complemented by LPG supply systems and physical customer service counters in Douglas and St Helier. Technology and customer-facing platforms include the MyAccount online billing portal (upgraded February 2025), the STASS robotic internal pipe repair technique (first deployed in the Channel Islands in 2024), and a Smart Home Shop offering partner products from Hive and Tado. The group retails Sunamp Thermino phase-change heat batteries through a partnership announced November 2023.
The business model is a traditional regulated utility go-to-market: recurring revenue from standing charges and consumption-based tariffs (e.g., Guernsey standing charge £1.13/month, Jersey £1.19/month, with 2025 gas price increases of 10% and 7.5% respectively), supplemented by one-time revenue from appliance sales and professional services for gas engineering, network operations and installation. Distribution is regional and direct via physical network connections, customer service counters, a group-wide call centre, and self-service digital portals. The group is repositioning from gas supply toward broader energy management under a published Net Zero by 2050 strategy with science-based 2030 emissions targets, supported by Achilles Carbon Reduce, ISO14001, ISO14064 and TCFD-aligned reporting.

Islands Energy Group competitors and assessment
Company assessmentDirect peers
- SGN (Scotia Gas Networks): SGN is one of the UK's four gas distribution networks, owning and operating the gas mains infrastructure that delivers gas to homes and businesses in Scotland, southern England and Northern Ireland. It is a direct comparable to Islands Energy Group in terms of regulated gas-distribution business model and physical network ownership, albeit at far larger scale.
- Cadent Gas: Cadent is the UK's largest gas distribution network, operating the gas mains across the North West, West Midlands, East Midlands, South Yorkshire and the North East of England. As a regulated gas-distribution utility serving residential, commercial and industrial customers, it is a direct functional peer to IEG's Guernsey Gas/Jersey Gas/Manx Gas operations.
- Wales & West Utilities: Wales & West Utilities operates the gas distribution network across Wales and the South West of England, serving residential and commercial customers. It is a closely comparable regulated gas network utility to Islands Energy Group's three island franchises.
- Northern Gas Networks: Northern Gas Networks operates the gas distribution network in the North of England, delivering gas to homes and businesses under a regulated GDN licence. It shares IEG's core activity of gas-distribution-network ownership and operation across a defined geographic franchise.
Regional players
- Guernsey Electricity: Guernsey Electricity is the States-of-Guernsey-owned integrated power utility supplying electricity to Guernsey through a submarine cable from Jersey and on-island generation. It is the directly adjacent electricity utility on the same island where IEG operates Guernsey Energy for gas, making it a natural cross-fuel peer.
- Jersey Electricity Company: Jersey Electricity is the vertically integrated power utility supplying electricity to the island of Jersey, operating generation, transmission and distribution assets. It is a directly adjacent franchise peer on Jersey (where IEG operates Island Energy for gas) and the most logical cross-fuel partner, supplier or counterparty in the Channel Islands.
- Manx Utilities Authority: Manx Utilities Authority is the Isle of Man government's statutory utility providing electricity, water and wastewater services across the island. It is a regional peer operating on the same island as IEG's Isle of Man Energy subsidiary and serves the same end-customers via a different but adjacent fuel.
Others
- Calisen / Crown Energy Infrastructure: Calisen owns and operates smart-meter and meter-asset-management infrastructure serving UK energy suppliers and consumers. It is an infrastructure-services peer, given IEG's operation of metering assets for its customer base and its MyAccount/billing infrastructure investment programme.
Broad incumbents
- SSE plc: SSE is one of the UK's largest regulated energy networks and renewable generators, operating electricity transmission/distribution networks and gas distribution. As a regulated utility with a strong Net Zero transition strategy and gas-distribution assets, SSE is a useful broad-incumbent comparator for IEG's transition playbook.
- British Gas (Centrica): British Gas is the UK's largest retail energy supplier and a subsidiary of Centrica, providing gas and electricity supply, boiler services and smart-home products to millions of UK households. As a broad incumbent it overlaps with IEG in retail gas supply, customer service operations and the Hive smart-thermostat product line that IEG now resells.
