MCS (Microgeneration Certification Scheme), the UK’s quality mark for small-scale renewables, has reported the best April on record for small-scale renewables
According to the MCS Data Dashboard, designed to provide near-real-time updates using MCS Installations Database (MID) data to track the adoption of small-scale renewable installations in the UK, there were more than 4,700 certified heat pump installations alone and 26,000 installations in total – a 22% increase on April 2024.
MCS CEO Ian Rippin said: “This brings the total for 2025 so far to over 20,000, as the Boiler Upgrade Scheme (BUS) – which requires the installation to be MCS certified – continues to support homeowners in making the transition to low-carbon heating. It was the three-year anniversary of the BUS on May 23rd, which has seen the number of applications to the scheme rise over the past 12 months.
“Solar PV also had a strong month, with 18,500 certified installations in April. This was a 19% increase on April 2024, building on the strong start to the year for solar, which has had the best start to a year for certified installations in over a decade this year.
“Battery storage continues its record-breaking start to the year with almost 2,900 certified installations in April – up 108% from April 2024 and bringing the total number of installations to over 36,000. After a record-breaking 2024, it’s great to see the adoption of low-carbon alternatives is continuing to grow at pace. As this momentum builds and installations are delivered at volume, it’s crucial to prioritise ‘delivered quality’ to strengthen consumer confidence in home-grown energy. That is at the core of the redeveloped MCS.”
