In summary, the Energy Company Obligation (ECO) is a government scheme in the UK designed to reduce carbon emissions and tackle fuel poverty. It requires large energy suppliers to fund energy efficiency improvements in domestic properties.
Key points of the ECO scheme include:
- Obligated suppliers: Large energy companies with over 150,000 domestic customers must participate.
- Target areas: The scheme focuses on low-income and vulnerable households, as well as those living in hard-to-treat properties.
- Measures: Typical improvements include loft insulation, cavity wall insulation, solid wall insulation, and boiler replacements.
- Funding: Energy companies bear the cost, which is usually passed on to consumers through energy bills.
- Eligibility: Households may qualify based on receipt of certain benefits, low income, or living in social housing with poor energy efficiency.
- Implementation: The scheme has gone through several versions since its inception in 2013, with the current phase being ECO4 – running from 2022 to 2026.
- Goals: The scheme aims to improve energy efficiency, reduce fuel poverty, and lower carbon emissions across the UK.
