Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if she will make an estimate of the number of households in Wales affected by (a) charges which represent a significant proportion of their income and (b) poor standards of workmanship under the Energy Company Obligation Scheme since July 2022.

The Energy Company Obligation (ECO) places a requirement on larger energy suppliers to deliver heating and insulation measures to eligible low-income and fuel poor households. Energy suppliers recoup delivery costs through consumer bills.

Homes benefitting from ECO4 will cut approximately £430 off their energy bills.

The Department does not hold data on the number of households affected by poor standards of workmanship under ECO. Through the ongoing evaluation of ECO4, we are gathering feedback from a sample of households on their satisfaction with installations.
