Boiler Upgrade Scheme: Biofuels

Question

To ask the Secretary of State for Energy Security and Net Zero, how many biomass boilers granted and installed under the Boiler Upgrade Scheme have had to be replaced due to faults in the installation or in the boiler in each of the last three years.

Answer

The Government does not hold specific data on the number of biomass boilers that have subsequently been replaced under the Boiler Upgrade Scheme. Ofgem, the scheme administrators, continue to work closely with the Microgeneration Certification Scheme (MCS) and consumer codes to monitor any complaints received, and to identify and resolve any issues with systems installed under the scheme.

Biomass deployment under the scheme represents a relatively small proportion of overall installations.
