Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of the Energy Company Obligation scheme on (a) the delivery of energy efficiency measures, (b) employment levels in the retrofit sector, (c) business viability in that sector and (d) support for households in fuel poverty.

Since ECO was launched in January 2013, it has delivered around 4.5 million measures in around 2.6 million properties (up to the end of February 2026). Of these measures, 52% were insulation measures while the rest were heating and micro-generation measures.

An evaluation of ECO4 is underway, which is looking at scheme impacts on supply chain growth, specialisation and workload from the perspectives of installers, as well as the proportion of ECO4 beneficiary households who were in fuel poverty prior to ECO4. Evaluation reports will be published later this year.
