Best-Ever August for Small-Scale Renewables Installations

THE LATEST DATA from the Microgeneration Certification Scheme (MCS) shows that August 2025 was the best August on record for certified small-scale renewables installations, bringing rooftop solar installations to 1.8 million since the scheme first launched.

Ian Rippin, MCS CEO

Ian Rippin, CEO at MCS, comments on the latest data: “Last month was the best August for small-scale renewables in MCS history, with over 25,400 certified installations.

“Figures from the MCS Data Dashboard show that battery storage continues its strong year with a total of 3,217 certified installations in August – a 105% increase on August 2024. With the Scheme now surpassing 50,000 all-time battery storage installations, more than half of these have been installed in 2025.

“The latest data also shows that there were almost 4,700 certified heat pump installations in August, as consumers continue to make the transition to low-carbon heating, driven by initiatives such as the Boiler Upgrade Scheme (BUS). This now means there have been over 40,000 heat pump installations in 2025.

“For solar PV, we saw more than 17,500 certified installations in August, bringing us to 1.8 million in the history of the Scheme.

Best-Ever August

“Off the back of a record-breaking first half of the year for MCS certified installations, it’s a positive sign to see us continue to reach important milestones. Our priority is to continue giving people confidence in home-grown energy, which is at the forefront of our redeveloped Scheme and the new-look MCS website.”

MCS holds comprehensive data on the uptake of small-scale renewable technologies across the UK on The MCS Data Dashboard. It provides near-real-time updates on renewable installations and is freely accessible.
