Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what steps his Department is taking to help minimise disruption to the wider supply chain during the transition from Energy Company Obligation 3 to Energy Company Obligation 4.

The Government introduced ECO3 Interim Delivery to help with the transition between ECO3 and ECO4 and to prevent a supply chain hiatus,. As suppliers and installers are familiar with ECO3 requirements, this has provided greater certainty prior to the regulations and final guidance.

In discussions, energy suppliers have confirmed that they have been using ECO3 Interim Delivery.

In addition, Ofgem has published the Full Project Scores and Partial Project Scores in advance of ECO4. This gives industry certainty on what ECO4 activities will be commercially worthwhile, helping to guide suppliers in planning and contracting.
