Microgeneration Certification Scheme (MCS) has published the core documentation for its Redeveloped Installer Scheme.
MCS stated that publishing the documents marks a “key milestone” in its journey to enhance standards for small-scale renewables. These changes “simplify and clarify” the certification process for Installers while maintaining robust technical and consumer protection standards, it said.
Key documents now available include the Installer Operating Requirements, Customer Commitment, MCS Installation Standards, and Pre-sale Information and System Performance Estimate Standards, along with an overview of the redeveloped Scheme structure in a diagram to show how they fit together.
A statement said that the full transition to the redeveloped scheme will take place throughout 2025 and into 2026 with a rolling transition. MCS stated that it is encouraging installers to review the materials, understand the new requirements and prepare for the changes.
It added that it will 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).
