As 2026 gets underway, the latest Microgeneration Certification Scheme (MCS) statistics show the continued surge in the UK’s renewable energy market and the opportunities this creates for installers. Whether you work with Solar PV, Heat Pumps, or Battery Storage, staying qualified and ready early in the year is key to meeting demand and maximising opportunities.

86,224 Total Installations in Q4

Between September and December 2025, the UK recorded 86,224 MCS-certified installations across heat pumps, solar PV and battery storage. These were completed by 5,636 certified contractors using 129,403 certified products, highlighting the scale of the industry and the growing need for qualified installers.

Key Trends from Q4 2025

Renewable technologies are no longer niche. Demand continues to rise across the board:

• Heat Pumps: 14,829 installations
• Solar PV: 58,708 installations
• Battery Storage: 10,789 installations

Heat pump installations dipped slightly due to seasonal demand, but the number of certified products increased by 197 from Q3, showing continued investment and confidence in the technology.

Solar PV installations rose by 1,897 from Q3 to Q4, with certified products up by 8,268, demonstrating strong momentum into 2026. Battery storage installations grew steadily throughout the year, from 8,047 in Q1 to 10,789 in Q4, highlighting its growing popularity as a complement to solar PV.

One thing is clear: renewable technologies are becoming standard in UK energy systems, and installers with the right skills and qualifications will be in high demand.
