About Decarbonising UK domestic heating: Disruptive approaches (2025)

This event was held at the Institution of Mechanical Engineers, London on the 21st of November, 2025 and featured a programme of presentations by leading industrial stakeholders

Including heat pump and electric boiler manufacturers, district heat network developers and gas distribution companies, as well as leading researchers from UK universities working in the field of heat decarbonisation . Antonia Mattos, head of energy research at the Department for Energy Security and Net Zero chaired.

In the UK, domestic space heating accounts for approximately 20% of the country’s carbon dioxide emissions. Combined, our domestic gas boilers emit twice as much CO2 as all the gas-fired power stations in the country.

One thing is very clear, we need to transform the way we heat our homes to reach Net Zero.

This event was supported by the Energy Research Accelerator (ERA) and the University of Nottingham Energy Institute, and brought together academics, industrial stakeholders, and policy makers to discuss the challenges around decarbonising space heating in the country but more importantly, to explore exciting real-world clean heat projects currently underway as well as innovative and potentially disruptive research work being carried out in UK universities that could accelerate our transition to zero-carbon heating.
