Heat networks play a crucial role in the UK's strategy to lower carbon emissions, yet their maintenance and improvement demand significant focus and resources. In navigating these challenges, accessing government funding becomes paramount.

Here's an insight into optimising your heat network maintenance practices and leveraging government funding initiatives, as well as Switch2's notable achievements in securing funding for our clients.

The Evolving Landscape of Heat Networks

Heat networks supply approximately 2-3% of the UK's heating needs, with ambitions to increase this figure to 20% by 2050. This vision entails substantial growth and improvements in the sector, necessitating significant investment in maintenance and upgrades. The majority of the UK's heat networks, primarily located in the residential sector and managed by building owners, have not been maintained to a standard that reflects cost and efficiency optimisation.

"Return temperatures are key in maintaining a good performing heat network. Controls need to be set properly and the distribution system balanced correctly. But settings will change over time, hence why maintenance is needed."

Ian Allan, Head of Market Strategy at Switch2, alongside Sam Hales, Low Carbon Consultant at Gemserv, in a recent webinar (Government Funding Initiatives) emphasised the importance of regular and thorough maintenance to prepare heat networks for impending regulations. This comes at a time when heat network operators continue to face inflated gas prices, highlighting the urgency for efficient network management.

The Critical Role of Maintenance

A well-maintained heat network is essential for operational efficiency and cost management. Proper settings and distribution system balance are key factors, but given that these settings evolve over time, continual maintenance becomes necessary.

Unlike standard heating systems, heat networks require a comprehensive approach—from the energy centre to the radiators—demanding expertise from contractors specializing in the entire network.

Data-driven insights into network performance are invaluable, helping pinpoint inefficiencies and prioritise maintenance needs. This analytical approach is more crucial than ever considering the ongoing energy crisis and rising operational costs.

Government Funding Initiatives: A Gateway to Enhancement

To support the expansion and enhancement of heat networks, the UK government introduced funding initiatives such as the Heat Network Investment Project and the Green Heat Network Fund in 2013. The Heat Network Efficiency Scheme (HNES) particularly focuses on reducing carbon emissions, improving customer confidence, and enhancing reliability.

Eligibility for funding spans district heat networks and communal heating systems across the public, private, or third-party sectors in England and Wales. The funding encompasses revenue grants for optimisation studies and capital grants for installation works, offering a pathway to upgrading old schemes to meet current standards.

Switch2's Success in Securing Funding

To date, Switch2 has illustrated exceptional mastery in securing funding for its clients, with over 50 applications successfully processed. This effort has translated into £2.97 million in grant funding for capital projects, with an overall project value nearing £6.1 million. This achievement underscores our commitment to enhancing the efficiency and sustainability of heat networks across the UK.

Looking Ahead: Apply for HNES Funding

While applications for Round 7 have now closed, we anticipate the release of details for Round 8 of the Heat Networks Efficiency Scheme (HNES) very soon.

At Switch2, we stand ready to support you through the application process and beyond. With our proven track record and in-depth industry knowledge, we aim to empower our clients to optimise their heat networks, ensuring they are well-positioned to meet future regulatory standards and achieve sustainable operation.
