Revenue model

1. Heat Network Development and Connection Fees: 1Energy develops low-carbon heat networks and generates revenue through connection fees from customers (public sector institutions, commercial buildings) connecting to the network. Networks are financed through a combination of private sector investment and government grants, with revenue earned as networks become operational and serve customers.
2. Government Funding (Green Heat Network Fund): The UK government's Green Heat Network Fund provides capital grants to support heat network projects. 1Energy has secured funding for multiple networks including Bradford (£20m), Milton Keynes (£17.6m), Oxford (£21m), Derby (£23m), Exeter (£42.5m), and Sunderland (£17.7m). This public funding reduces the cost of network development.

Core offering

1Energy develops, finances, builds and operates low-carbon district heat networks across UK cities. The company delivers city-scale heating infrastructure that distributes renewable heat from central energy centres (using large air source heat pumps, water source heat pumps, and recovered waste heat from data centres) through underground pipes to public sector and commercial buildings, reducing heating carbon emissions by at least 75% from day one of connection.

Product overview

1Energy is a UK low-carbon heat network developer offering city-scale district heating infrastructure. The portfolio consists of six distinct regional heat network products: Bradford Energy Network (£75m), Exeter Energy Network (£120m), Milton Keynes Energy Network (£95m), Oxford Energy Network (£121m), Derby Energy Network (£100m+), and Sunderland Energy Network (£67m). Each network operates as a standalone infrastructure project, with shared underlying technology using air source heat pumps, water source heat pumps, and waste heat recovery from data centres. All networks are financed through a combination of Green Heat Network Fund grants and private investment, with no council or community capital required.

Products and services

• Bradford Energy Network A £75 million city-wide low-carbon heat network in Bradford, West Yorkshire, powered by one of the UK's largest air source heat pump systems at the Thornton Road Energy Centre. The network delivers 75% reduction in heating emissions from day one for connected customers and is connected to Deep Green's 5.6MW data centre via closed-loop cooling for waste heat reuse.
• Exeter Energy Network A £120 million low-carbon heat network in Exeter city centre backed by £42.5 million Green Heat Network Funding. Uses air source heat pumps at Grace Road Energy Centre to deliver renewable heat through underground pipes, saving 13,000 tonnes of carbon emissions annually and delivering a 91% reduction in nitrous oxides.
• Milton Keynes Energy Network A £95 million low-carbon heat network in Milton Keynes utilising air source heat pumps and waste heat recovery from data centres. Set to cut the city's carbon emissions by 15,800 tonnes per year and reduce air pollution by 80%, with capacity equivalent to supplying 20,000 homes.
• Oxford Energy Network A £121 million low-carbon heat network in Oxford city centre backed by £21 million Green Heat Network Funding. When completed in 2030, will reduce Oxford's reliance on fossil-fuel gas by 10% and cut carbon emissions by 15,000 tonnes annually.
• Derby Energy Network A landmark £100+ million city-wide low-carbon heat network for Derby backed by £23 million Green Heat Network Funding. Powered by water-source heat pumps capturing surplus heat from local industry, reducing air pollution by up to 86% and saving 19,000 tonnes of CO2 annually.
• Sunderland Energy Network Sunderland's first low-carbon heat network developed in partnership with Sunderland City Council. £67 million investment drawing on innovative low-carbon technology and waste heat from a planned data centre to deliver clean, reliable heat to public and commercial buildings, achieving 70% less CO2 for connected buildings and saving 13,838 tonnes of CO2 per year.

Broad incumbents

• Equans UK: Bouygues subsidiary providing district heating, energy services and decarbonization solutions across the UK and Europe. Comparable as a heat network developer serving public sector customers with combined heat and power and low-carbon heat solutions.
• E.ON UK: Major UK utility with heat network development, district heating operations and energy solutions for public sector customers. Directly comparable as a heat network developer with institutional anchor customers, but operating as a broad incumbent with gas, power and heat businesses.
• SSE Heat Networks: UK utility with district heating operations and decarbonization projects for cities and communities. Comparable as a heat network operator and developer, though SSE operates a much broader regulated and renewable energy portfolio.
• ENGIE UK: Multinational utility with a UK district heating and decarbonization business serving cities, campuses and public sector customers. Comparable as a large incumbent developing low-carbon heat networks across UK cities, though operating across a much broader portfolio.
• Centrica: Major UK energy supplier and solutions provider with distributed energy and business energy services for public sector customers. Comparable given 1Energy's CEO background at Centrica, though Centrica operates a much broader energy retail and services portfolio.

Regional players

• Vattenfall Heat: European utility operating one of the largest district heating networks, primarily in Sweden, the Netherlands and Germany. Comparable as a major district heating developer with deep experience, though primarily serving continental Europe rather than the UK.

Others

• Deep Green: UK data centre operator that captures waste heat for direct supply to district heating networks, including 1Energy's Bradford Energy Network. Comparable as a strategic partner enabling 1Energy's low-carbon heat source, rather than as a direct competitor in heat network development.

Direct peers

• Hemiko: UK heat network developer focused on low-carbon district heating using heat pumps and waste heat sources for cities and industrial customers. Closely comparable as a privately-funded UK heat network developer at similar stage, targeting public sector anchor customers.
• Vital Energi: The UK's largest private district heating and energy services company, operating and developing heat networks for public and private sector customers. Directly comparable as a UK-focused heat network developer with NHS, university and council customers and similar low-carbon heat sources.

Emerging players

• Kensa Heat Pumps: UK manufacturer and installer of ground source heat pumps, including network-style shared ground loop arrays for housing developments. Comparable as a UK-based low-carbon heat provider, though focused on smaller-scale, building-level rather than city-scale networks.
