Why These ECO4 Heating Grants Matter More Than Ever
- Cut energy bills by up to 30–40% (as per standard assumptions)
- Stay warm, cosy, healthy, and safe during harsh winters
- Reduce carbon emissions and improve your EPC rating
- Upgrade old heating systems with no upfront cost
Grab this opportunity to get a free heating upgrade and stay warm this winter!
Why Your EPC Rating Matters
EPC stands for your home’s Energy Performance Certificate. It shows how energy-efficient your home is. Properties rated E, F, or G often waste heat, are expensive to heat, and struggle to stay warm.
With ECO4 and LA Flex grants, you can:
- Improve your EPC rating from F/G → C or even B
- Cut fuel bills by reducing wasted energy
- Improve comfort with modern heating and insulation
- Lower your carbon footprint while staying cosy.
