The response to the ECO4 consultation was published on 1 April 2022: https://www.gov.uk/government/consultations/design-of-the-energy-company-obligation-eco4-2022-2026
A 3-month interim delivery phase has been introduced between 1 April – 30 June 2022, under the previous (ECO3) scheme rules, to enable delivery to continue subject to some fossil fuel heating limitations. Obligated suppliers may also choose to deliver under the new scheme rules during this period.
BEIS and the scheme administrator, Ofgem, meet and communicate regularly with obligated suppliers to provide further clarity on the scheme rules.
The Government is planning to lay regulations as soon as possible, to provide the market with legislative certainty.
