Understanding the ECO4 Scheme

The ECO4 (Energy Company Obligation Phase 4) scheme is a UK government energy efficiency program regulated by Ofgem, the energy regulator. Running from April 2022 to March 2026, ECO4 mandates that large energy suppliers fund energy-saving measures for low-income and vulnerable households across England, Scotland, and Wales.

Key Benefits of ECO4 Funding

  • 100% Free Installation: No upfront costs or hidden fees. The scheme covers assessment, installation, and certification.
  • A-Rated Equipment: All boilers installed must achieve minimum 90% energy efficiency ratings, certified by Gas Safe registered engineers.
  • Significant Energy Savings: Average households save £800-£1,200 annually on heating bills, with payback through reduced energy consumption.
  • Increased Property Value: Improved EPC ratings (Energy Performance Certificates) can increase property values by 5-10% on average.
  • Environmental Impact: Reduce your carbon footprint by an average of 2.5 tonnes of CO₂ emissions annually, contributing to UK climate goals.
