Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent assessment she has made of the adequacy of the certification programme for the Domestic Renewable Heat Incentive.

The Microgeneration Certification Scheme (MCS), which is the leading standards and quality assurance organisation for microgeneration technologies in the UK, is the certification scheme for the Domestic Renewable Heat Incentive (RHI). All installers that participate in the RHI are required to be a member of MCS.

MCS conducted a public consultation on its operating model in 2023, and is currently implementing a programme of reform to strengthen its support for consumers. The department continues to work with MCS and its stakeholders to monitor the impact of these reforms.
