Trends and Insights
The Smart Export Guarantee (SEG) brings renewed life to the UK solar industry
- The introduction of the SEG since January 2020 has spurred an upward trend in solar panel installation. The SEG is a government-backed scheme that enables homeowners and small businesses that adopt a renewable energy system to earn money by selling excess electricity back to the National Grid. This has encouraged more people to go solar and driven a surge in industry revenue. The scheme means that only installations carried out by installers certified by the Microgeneration Certification Scheme (MCS) are eligible for funding, driving high-quality installations that can command a higher price.

Trends and Insights
Stringent building regulations and government plans will hike solar panel installations
- As sustainable energy becomes the norm, growing government mandates for more sustainable solutions will support continued growth in solar panel usage. In October 2024, a cross-party group of MPs, environmental groups and fuel poverty charities urged the government to mandate solar panels on all new-build homes from 2025 as part of the Future Homes Standard (FHS). The programme is not yet active, but is expected to be implemented in the coming years. Once the programme is fully operational, installers can expect a surge in residential installation demand, encouraging companies to focus their efforts on the residential market.
