More ways to fund your renewable energy system
The BUS grant is not the only funding available. Depending on your income, property type and location, you may qualify for fully-funded or heavily-subsidised renewable energy.
Could ECO4 help fund improvements to your home?
What is ECO4?
Ofgem states that ECO4 runs until 31 December 2026. Funding depends on eligibility, assessment and supplier availability; an enquiry does not guarantee funded work. Read Ofgem guidance.
The Energy Company Obligation (ECO4) scheme requires energy suppliers to fund energy efficiency improvements — including solar PV, heat pumps and insulation — for low-income and vulnerable households. If you qualify, the work can be fully funded at no cost to you.
Warm Homes Programme Wales
The Welsh Government's Warm Homes Programme provides funding for energy efficiency and renewable energy improvements for households in fuel poverty or on low incomes in Wales. This can include solar PV, heat pumps, insulation and boiler upgrades.
ECO4 eligibility — you may qualify if...
- ✅ You receive means-tested benefits (Universal Credit, Pension Credit, etc.)
- ✅ Your property has an EPC rating of D, E, F or G
- ✅ You are a homeowner or private tenant (with landlord consent)
- ✅ Your household income is below a certain threshold
