Latest data from the MCS Data Dashboard shows that March was the best month of 2025 so far, totalling more than 31,000 certified renewable installations – up 49% from March 2024.
Ian Rippin, CEO at MCS, said: “Heat pump uptake continues to rise, with 5,604 certified installations – a 22% increase on March of last year – as more homeowners transition to low-carbon heating, driven by initiatives such as the Boiler Upgrade Scheme (BUS).
“Solar PV also had a strong month, with a total of 22,599 installations in March. This was a 49% increase on March 2024 and an 18% increase on last month. This means that there are now over 1.7m MCS certified solar PV installations.
“March was another record-breaking month for battery storage, with almost 3,000 certified installations, beating the previous record set in February and a 147% increase on March 2024. This brings the total battery storage installations to over 33,000.
“It’s great to see that the number of people adopting low-carbon alternatives is continuing to grow month on month, a positive step towards helping the UK achieve its net zero targets. With this growth, it is crucial to focus on ‘delivered quality’ to ensure consumers have growing confidence when investing in home-grown energy. This is what the redeveloped MCS will achieve, putting consumer protection at the heart of what we do.”
Meanwhile, latest Boiler Upgrade Scheme figures for March show the highest number of applications since the scheme began and exceeded 4,000 for the first time.
Gav Murray, Hive heating director at Centrica New Business Net Zero, said: “March’s uplift in Boiler Upgrade Scheme applications is another win for the scheme, as interest grows, and more homeowners enjoy the power of cleaner and more affordable energy.
“The continued success of the scheme is great to see, but the number of homeowners taking advantage of the BUS grant is still relatively small when you consider the government’s ambitious targets.
“To speed up adoption, the government must consider extending the grant to include other forms of low-carbon heating such as low-carbon boilers, because the reality is that not every UK property is currently suitable for standard heat pump technology.
“Expanding the scheme will ensure all homeowners have viable pathways to embracing the future of home heating.”
