OFTEC is reminding all technicians registered under the current MCS installer scheme that they need to transition to the redeveloped Microgeneration Certification Scheme (MCS) framework by 31 March 2027.
OFTEC is reminding all technicians registered under the current MCS installer scheme that they need to transition to the redeveloped Microgeneration Certification Scheme (MCS) framework by 31 March 2027.

Businesses that do not complete the transition by this deadline will no longer be able to remain registered under the old MCS scheme, potentially affecting access to work and programmes where MCS certification is required.
The redeveloped MCS has been designed to better reflect the needs of today’s renewables sector. Instead of placing significant emphasis on paperwork and internal processes, the new framework focuses more on installation quality, consumer outcomes and installer competence.
For MCS-certified businesses, the redeveloped scheme offers several benefits, including:
While March 2027 may seem some way off, transitioning to the redeveloped scheme will require planning and preparation. Businesses should review the new requirements, ensure relevant staff understand the changes and begin the transition process as early as possible.
By acting now, installers can avoid any disruption to their certification status and continue to demonstrate their commitment to delivering high-quality renewable energy installations.
