What does MCS certified mean?
In short
MCS certifies installers of small-scale renewable technology, such as solar panels and heat pumps. Using an MCS-certified installer is usually needed to get paid for exported power and to claim heat pump grants.
What it is
MCS is a UK scheme that sets standards for installers and products in small-scale renewables, including solar panels, batteries and heat pumps.
Why it matters
Energy suppliers usually ask for an MCS certificate before they'll pay you for power you export. The Boiler Upgrade Scheme grant for heat pumps also needs an MCS-certified installer.
How to check
You can search the MCS website for an installer's certification. Ask for their MCS number on the quote.
