The UK’s leading low-carbon city heat network developer, 1Energy, has secured £21m of investment from the government for a city-wide heat network for Oxford.
 
The company plans to initially invest an additional £100mn of private capital to develop, build and operate the first phase of the Oxford Energy Network. 1Energy’s investment into the project over time could amount to more than £500m as the network expands to connect more buildings.
 
Alongside engaging major institutions in the city – Oxford City Council, Oxfordshire County Council, the Zero Carbon Oxfordshire Partnership (ZCOP), Oxford Brookes University and the University of Oxford – 1Energy is working to advance the network, with plans to begin construction in 2026 following engagement with the local community and securing planning consent.
 
By initially targeting organisations with high heat consumption, the project could reduce Oxford’s fossil-fuel gas demand by up to 10 per cent. The network is also projected to reduce carbon emissions by 15,000 tonnes a year – approximately two per cent of Oxford’s entire annual emissions – by cutting emissions from connected buildings by up to 81 per cent.
 
The project will enable the world-leading city to decarbonise heating, a major source of air pollution and carbon emissions in the UK. Some of Britain’s most iconic, grade-one listed buildings in the city could soon be warmed by low carbon heat rather than gas boilers.
 
1Energy’s approach complements the environmental leadership shown by Oxford and ZCOP, aligning with the city’s ambitious plans to decarbonise while respecting its architectural character and historic setting. The network intends to help lay the foundations for a healthier, cleaner future for its residents.
 
As well as helping Oxford achieve its climate goals, the project expects to improve the lives of those who live and work in the city by reducing air pollution, improving public health. The network is projected to reduce the amount of air pollutants that can cause respiratory problems by five per cent before 2030. 1Energy has established a community benefit task group – that includes major institutions in the city – that is exploring how the network can support community projects, tackle fuel poverty and boost local employment.
 
 
Andrew Wettern, CEO of 1Energy, said:

“Oxford is already at the very forefront of city decarbonisation and low carbon energy through the work of the University, and the Zero Carbon Oxfordshire Partnership and its constituent members. We are thrilled to add to this success by enabling the city to decarbonise heat through the Oxford Energy Network.”
 
“Oxford has more than 1500 listed buildings across the city, so the decarbonisation challenge for Oxford is much harder than many other cities. The Oxford Energy Network matches perfectly to the challenge because it will be invisible and silent, it will supply the temperatures required by these historic buildings to maintain their warmth in the winter, and it will be easier and cheaper for customers to connect to the network than to create their own low-carbon heat onsite.”
 
“By using the Oxford Energy Network as a model for other historical cities and towns, we can deliver heat decarbonisation in a way that preserves our heritage, across many more cities and towns at pace.”
 
 
City-wide evolution

Home to the Oxford Leading Sustainable Corporations Programme and Oxford Institute for Sustainable Development, the city has long led the global conversation around sustainability. World-renowned organisations across the city have also set ambitious air pollution targets and climate goals that require them to rapidly move away from gas boilers.
 
Heat networks offer the lowest-cost, simplest, fastest route to decarbonising heat in cities and towns, requiring the fewest building-retrofit measures. As this low carbon heat is transferred via underground, water-filled pipes, they also preserve the aesthetic of our historic city centres.
 
The Oxford Energy Network will bolster the city’s stature, adding another element to its long-standing leadership on sustainability.
 
As the first company in the UK to use ‘deep green’ private capital to build city-scale low-carbon heat networks like the Oxford Energy Network, 1Energy has ambitions to deploy £1bn within the next 8 years into new low carbon heat networks across the UK – decarbonising heat in additional national landmarks.
 
Through reducing the use of gas, these networks help reduce public health costs and protect organisations against sudden gas-related energy price hikes.
