Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether his Department has issued guidance to installation companies on the standards to which insulation and energy efficiency measures should be installed under government schemes.

Energy efficiency measures installed in households under current Government schemes must be done in accordance with the Publicly Available Specification (PAS) 2030 and PAS 2035 standards.

Installers under Government schemes must also be TrustMark registered. As the only Government endorsed quality scheme, TrustMark ensures compliance with the overarching PAS 2035 process and setting clear requirements to protect consumers across the multiple sectors operating in the energy efficiency market.
