Progress towards Obligation
Progress towards Phase 1, 2 and 3
To achieve its ECO obligations, a supplier must install measures that qualify under the scheme and deliver annual bill savings for the household.
ECO4 sets a main obligation called the Home Heating Cost Reduction Obligation (HHCRO), which requires energy suppliers to achieve a total of £224.3 million in annual bill savings for domestic premises by 31 March 2026.
The obligation is divided between energy suppliers based on their respective shares of the domestic gas and electricity market.
A supplier meets its obligations under ECO4 by promoting qualifying actions (‘measures’) at eligible domestic premises, and must do so in full no later than 31 March 2026.
The overall obligation period for ECO4 runs from the commencement of the ECO4 Order on 27 July 2022 to 31 March 2026 and is split into four phases:
• Phase 1: 27 July 2022 to 31 March 2023
• Phase 2: 1 April 2023 to 31 March 2024
• Phase 3: 1 April 2024 to 31 March 2025
• Phase 4: 1 April 2025 to 31 March 2026
A supplier’s total obligation is determined by adding together their obligations for each phase. They must meet their total obligation by the end of 31 March 2026.
