This latest announcement of £8.1 million brings the total awarded under HNES, funded by the Department for Energy Security and Net Zero, to £25 million. Thirty-four heat networks will benefit, helping to increase operating efficiencies and improve the heating experience of over 9,000 residents, hospital patients, students and public sector workers.
The capital grant funding will result in annual carbon savings of over 89,000 tCO2e per year over the next 40 years. Simultaneously, the secured revenue grant funding will facilitate optimisation studies, unlocking opportunities to identify additional carbon savings in the coming years.
UK is a world leader
Lord Callanan, minister for energy efficiency and green finance, has welcomed the HNES funding announcement: “Everyone – from families and hospital patients to students and public sector workers – should be able to receive a reliable heating and hot water supply.
“The UK is a world leader when it comes to cutting carbon emissions, and while we are committed to funding new, greener heat networks, we also need to update our inefficient systems so everyone can enjoy the benefits and this funding is aimed at doing exactly that.”
Louise Singleton, principal consultant at Gemserv and HNES programme manager, added: “We are delighted to know that funding from HNES is translating into real-world benefits. Round 3 grants will help to unlock tangible cost reductions and higher heating efficiency for 9,000 residents, as well as hospitals and university students.
“Revenue funds also present a huge opportunity to unlock benefits for countless more heat network customers across England and Wales. We are excited to start working with our funded projects to facilitate the use of low-cost, energy-efficient heating and support the UK’s journey on the pathway to net zero.”
Below is a summary of the projects successfully securing HNES funding in round 3.
Capital grant funding
Capital grant funding will go directly towards covering the cost of operational works to improve the efficiency of existing heat networks. In this round, over £7.6 million will improve heat networks serving over 5,000 residents.
Housing Associations and Social Housing Providers
Consort Road (aka Sarawak Court)
Notting Hill Genesis has been awarded £725,661 for the Consort Road heat network. Funding will unlock a complete system replacement, including a new energy centre, pipework and control units. Forty-nine residents will benefit from planned improvements.
Duffryn District Heating System
Newport City Homes Housing Association Limited has been awarded £3,715,972 for the Duffryn District Heating System. Funding will go towards replacing over 3km of pipework across the network while upgrading control systems and insulation. This work will improve the network’s performance for over 970 homes, local schools, and businesses.
The Guinness Partnership has been awarded £461,435 for the Cottesmore House heat network. Funding will change the network from a 4-pipe system to a 2-pipe system to help reduce heat losses and energy consumption. Forty-eight residents will benefit from network improvements.
Seascape Management Limited has been awarded £36,548 for The Banks heat network. Funding will go towards replacing existing network equipment to help modernise the network, including pumps and insulation measures, bringing the network’s infrastructure up to current standards. Improvements will benefit 74 residents.
E.ON UK has been awarded £1,562,274 for the Cranbrook heat network. The funding will enable the retrofitting of Heat Interface Units in residents’ homes to provide better reliability, more efficient units, and reduced heat losses. Efficiency improvements will be carried out in the early phases of Cranbrook but will benefit over 3,000 residents across the network.
One Brighton Energy Services Ltd has been awarded £54,484 for the One Brighton heat network. This is the second phase of the improvement works after having received HNES Demonstrator funding in 2022. This project will reinsulate secondary pipework and valves across the network to increase efficiency levels and reduce heat losses. Improvements across the network will benefit hundreds of residents and a large community building.
Vattenfall’s Redcliffe Heat Network
Bristol Heat Networks Limited has been awarded £746,582 for the Redcliffe Heat Network, owned and operated by Vattenfall. Funding will help replace the pipework across the primary network. Seven hundred forty residents will benefit from these network improvements.
Health and education organisations
University of Plymouth, Portland Square
The University of Plymouth has been awarded £243,280 to upgrade to a sustainable heating system in the Portland Square area of its campus. The funding supports the University’s decarbonisation plan by improving the efficiency of the network to allow fossil fuel-powered appliances to be replaced with heat pumps and electric boilers in the future.
Revenue grant funding
Projects across England and Wales in round 3 have also been awarded over £486,000 of revenue grant funding to undertake optimisation studies to review their heat networks’ performance and identify improvement areas.
The following organisations have been awarded revenue grant funding for optimisation studies:
Housing associations and social housing providers
Notting Hill Genesis, for the Baths Court heat network to investigate high gas usage and suggest ways to reduce outages and overheating.
The Hyde Group, for the Packington heat network.
Connect Housing Association Limited for the Ancion Court, Hawthorn Mill, and Nowell Court heat networks to review efficiency levels and address overheating issues.
Worthing Homes Limited, for the Caxton Court and Davenport Court heat networks to review efficiency levels.
Wakefield and District Housing, for the Smirthwaite, Park Dale and Monument Mews heat networks to review efficiency levels and assess flow temperatures throughout the year.
SNG (Sovereign Network Group), for the Biko House and Atrium Point heat networks to address overheating issues, leaks and heating interruptions and reduce consumer costs.
Waltham Forest Council, for the Aldriche Way Estate heat network, to investigate efficiency levels and high costs.
