The UK’s renewable energy sector continues to surge and the latest MCS data confirms it. Today, we’re breaking down the Q3 2025 figures, highlighting trends across heat pumps, solar PV and battery storage, showing why there’s never been a better time to upskill or build a career in renewable energy.

84,640 Total Installations

Between July and September 2025 (Q3), the UK recorded 84,640 MCS-certified installations across heat pumps, solar PV and battery storage – a clear sign that the renewable energy sector continues to gain serious momentum. Behind these installations are 5,624 certified contractors, ensuring high-quality work and a market offering 120,938 certified products, giving homeowners and businesses a wide range of reliable options.

From Q1 and Q2, the market is continuing to mature, with certified products increasing by 45,858 since the end of June. This growth highlights not only the expansion of the sector but also the increasing availability of high-quality, certified technologies for homeowners and businesses.

These numbers don’t just present growth, they showcase opportunity. For anyone considering expanding their skills in the renewable energy industry, the demand has never been higher.

Heat Pumps: Back on the Rise

Heat pump installations have made a strong comeback in Q3, showing clear recovery after a dip earlier in the year. Following a drop from 14,436 installations in Q1 to Q2’s lower figures, Q3 saw numbers climb to 15,150 installations – a positive increase that reflects growing confidence and adoption across the UK. The number of certified contractors now stands at 2,220, with 4,132 certified products on the market, both of which have surged this quarter.

It’s clear that heat pumps are here to stay. As technology improves, incentives continue and consumer awareness grows, this low-carbon heating solution is becoming a mainstream feature of the UK’s transition to cleaner, more efficient homes.

Solar PV Momentum Continues in Q3

Solar PV continues to dominate the UK’s renewable market, bouncing back after a slight decrease in Q2. Q3 saw 58,708 installations, supported by 4,344 certified installers – a notable increase from earlier quarters and a clear sign of ongoing momentum.

For context:

• Q1: 57,039 installations
• Q2: 55,655 installations
• Q3: 58,708 installations

This upward trend demonstrates that solar PV remains the backbone of the UK’s renewable sector. The rise in both installations and certified installers highlights strong demand, a growing workforce and a market increasingly confident in embracing solar technology.

Battery Storage: Reaching New Heights

Battery storage installations have been on a strong upward trajectory throughout 2025 and Q3 confirms the sector is accelerating. Following a solid start in Q1 and Q2, certified installs have now hit 10,782, supported by 2,481 certified installers – a substantial increase that highlights the growing uptake of energy storage solutions.

For comparison:

• Q1: 8,047 installs
• Q2: 8,565 installs
• Q3: 10,782 installs

This surge demonstrates that battery storage is becoming a mainstream part of the UK’s renewable energy ecosystem. With more installers entering the market and technology adoption increasing, the sector presents significant opportunities for professionals looking to upskill in low-carbon technologies.

Pairing solar PV with battery storage adds even more value – enabling homeowners and businesses to save energy and reduce costs, whilst installers deliver fully integrated low-carbon solutions.
