MCS publishes new installer scheme details
2nd February 2025
UK: The operator of the Microgeneration Certification Scheme (MCS) has now published the core documentation for the proposed redeveloped installer scheme.
These changes will simplify and clarify the certification process for Installers while maintaining robust technical and consumer protection standards.
Key documents now available include the Installer Operating Requirements, Customer Commitment, MCS Installation Standards, and Pre-sale Information and System Performance Estimate Standards.
While the full transition to the redeveloped scheme will take place throughout 2025 and into 2026 with a rolling transition, MCS is encouraging Installers to review the material, understand the new requirements and prepare for the changes.
In a statement, the MCS said: “We’ll be working closely with certification bodies to help support them through the process of updating their accreditation for the redeveloped scheme from the UK Accreditation Service (UKAS).”
While the timeline for this is dependent on UKAS, MCS certified installers must adhere to the existing scheme requirements (including MCS 001-1) until they have been transferred onto the redeveloped scheme.
Membership of a consumer code will also need to to be maintained membership as does the need to continue purchasing insurance-backed guarantees.
“We expect a rolling transition period which will likely last into 2026, but these timescales are not yet clear,” the MCS said.
Further information can be found on the MCS website.
