Question to the Department for Energy Security & Net Zero:
To ask the Secretary of State for Energy Security and Net Zero, what information his Department holds on the number of (a) gas boilers, (b) oil boilers, (c) heat pumps and (d) biofuel boilers there were in 2023; and if he will make an estimate of the number of each there will be in 2030.
The department only collects data on installations under Government Energy Efficiency schemes and does not hold data on privately installed heating systems. The latest heat pump deployment figures can be found here: www.gov.uk/government/statistics/heat-pump-deployment-statistics-september-2024.
Measures installed under the ECO scheme, the Home Upgrade Grant and the Social Housing Decarbonisation Fund can be found here:
Gas boilers will continue to play a role for at least the next decade as we transition to low carbon heating technologies, where departmental analysis shows that heat pumps and heat networks will have a major role to play.
Where heat pumps may not be feasible in some off-grid properties we have commissioned a package of research to collect data on the costs of different approaches to decarbonising the most complex housing archetypes, including the use of alternative low carbon heating solutions with results expected in 2025.
