The MCS Installations Database, sometimes abbreviated to the MID, is a central online database that holds the information of every MCS certified small scale, low carbon installation in the UK since 2010.
The MID is the most comprehensive reference for small scale, renewable energy installations in the UK. It is unique to MCS.
The MID continues to be the single reference point for compliant installation information, used by both industry (energy suppliers) and the regulator, Ofgem. MCS has a data sharing agreement with BEIS and Ofgem to facilitate their regulatory activities and to inform policy development.
All MCS installations require registration through the MID. A certificate shall be obtained from the MCS Installation Database for each installation and shall be provided to the customer no later than 10 working days after the date of commissioning the system.
This MCS Certificate can be used by the customer to obtain eligible financial incentives. It is also used by Energy Suppliers to verify the eligibility of an installation.
All MCS certified products are listed in the MCS Installations Database. This enables Installers to review and select appropriately certified products to complement their installation.
