Unlocking Opportunity with District Heat Networks in the UK
The UK’s decarbonisation journey hinges on one of the most pressing and complex challenges in the energy landscape; heat. Responsible for nearly 37% of the UK’s greenhouse gas emissions, heating homes, businesses, and industry remains one of the largest obstacles to achieving net-zero by 2050.
While the electrification of transport has gained momentum, and the decarbonisation of power generation has made remarkable progress, heat has proven more difficult to crack.
One of the most promising and scalable solutions? District heating networks.
The Role of Heat Networks
Heat networks are central to the UK’s strategy for decarbonising heat. Currently, they provide about 3% of the UK’s heat demand, but the government aims to increase this to 20% by 2050. These networks distribute heat from a central source to multiple buildings, allowing for the efficient use of low-carbon heat sources and reducing reliance on individual fossil fuel-based heating systems.
Key Developments: The UK’s £100 Million Leap Toward Low-Carbon District Energy
The UK government has recently announced a significant investment of over £100 million through the Green Heat Network Fund (GHNF), marking the largest funding round to date. This initiative aims to accelerate the development of low-carbon heat networks across England, supporting innovative projects that harness waste heat from various sources such as rivers, data centres, and sewage systems.
This is a strong signal of growing momentum, but the real opportunity lies beyond the numbers. The scale and diversity of the UK’s building stock, combined with its ambitious climate commitments, make the case for widespread heat network deployment stronger than ever.
At the same time, policy support is maturing, alongside the newly released market framework for heat networks, consumer protections and mandatory zoning. This will help unlock private investment and standardise delivery. These changes are designed to ensure not just efficiency, but fairness, providing end users with reliable, affordable, and low-carbon heat.
GHNF: Catalysing the Heat Network Sector
The recent GHNF funding round, supports eight projects across London, Bristol, the West Midlands, Lincolnshire, and the North West.
Vattenfall has been awarded £21.3 million to develop a network combining the Frome Gateway, Canons Marsh, and St. Nicks’ areas. The project will utilise air and water source heat pumps, electric boilers, and thermal storage to provide low-carbon heat.
1Energy is set to receive £23.2 million to implement a heat network using 12MW water source heat pumps that recover waste heat from the Spondon area. The network aims to connect up< to 47 buildings, including educational institutions and healthcare facilities.
Hemiko has secured £15.5 million to construct a network utilising waste heat from a purpose-built data centre. The project is expected to unlock £62 million in private investment for its first phase and create 40 local jobs over five years.
The SWAN Partnership has been granted £21 million to develop a network that recovers heat from local sources, aiming to supply low-carbon heating to iconic buildings across Victoria, Whitehall, and the Strand.
Sandwell Metropolitan Borough Council will receive nearly £5 million to build a town-wide network supplied by heat from the Enfinium Kelvin Energy from Waste Facility, targeting residential and public buildings.
Trafford Council has been awarded £5.7 million to develop a network using heat pumps that recover waste heat from a local sewerage system, serving various public and residential buildings.
Severn Wye Energy Agency is set to receive £1.7 million to create a network delivering excess heat from a biochar production facility to buildings in a Warrington business park.
Bring Energy has secured nearly £9 million to extend an existing network in the Olympic Park area, incorporating dual heat pump systems that recover waste heat from a local river and existing King’s Yard energy centre.
Local Authorities and Heat Networks
For local authorities, the rise of heat networks presents a unique opportunity to lead the transition. Councils are uniquely placed to coordinate local energy strategies, unlock land for infrastructure, and engage stakeholders across public and private sectors.
Moreover, local networks bring local benefits, creating jobs, reducing fuel poverty, and building resilience into energy systems. Unlike traditional gas boilers, district heating can evolve with future technologies and integrate multiple sources, from solar thermal to hydrogen-ready systems.
Colloide’s Role in Advancing Low-Carbon Heat Networks
Delivering this transformation will require trusted, experienced partners. At Colloide, we are proud to contribute to the UK’s transition to sustainable heating solutions. Our experience includes nationally recognised schemes such as the Viking Energy Network in Jarrow, which uses the River Tyne to supply public buildings, and the Bloomsbury Heat and Power Network, which supports dense urban development in London.
We understand the complexities involved, from engineering design to stakeholder engagement. We are committed to collaborating with local authorities and private partners to develop and deliver low-carbon heat networks that align with the UK’s net-zero targets.
