Who Can Qualify for Free or Discounted Solar Panels?
You’re more likely to qualify if you meet the following:
- You own your property (not renting).
- Your EPC rating is D or below.
- You receive income-based benefits (Universal Credit, Pension Credit, etc.).

Environmental Impact
A standard 4 kW solar system can offset nearly 900 kg of CO₂ per year — roughly equal to planting 40 trees annually.
You’ll reduce your carbon footprint while supporting the UK’s Net Zero 2050 goals.
