Ian Rippin, chief executive at MCS, commented on the latest MCS data: “Battery storage saw its best month ever, with over 2,600 installations - a 176% increase compared to January 2024. This surge is underpinned by the growth of our certified battery storage installer base, which now exceeds 2,000.

“Heat pumps also continue their upward trajectory, with 4,902 installations recorded in January - up 21% on January last year - as more homeowners make the switch to low-carbon heating. This brings the UK’s total number of certified heat pump installations to 280,992 as of the end of January 2025.”

MCS holds the most comprehensive repository of data on the uptake of small-scale renewable technologies across the UK on The MCS Data Dashboard.
