Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how much funding remains available in Phase 3 of the Energy Company Obligation 4 (ECO4) scheme.

ECO4 funding is not released through a tranche system. The scheme sets a legal obligation on energy suppliers, and this is divided between energy suppliers based on their respective shares of the domestic gas and electricity market. Energy suppliers are permitted to deliver their obligation at their preferred pace over the life cycle of the scheme, between April 2022 and March 2026. The total value of ECO4 is £4 billion. This breaks down to £1bn a year for the four years of the scheme.
