Asked by: Anneliese Dodds (Labour (Co-op) - Oxford East)

Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment his Department has made of the value for money of the Energy Company Obligation scheme.

Answered by Miatta Fahnbulleh - Parliamentary Under Secretary of State (Department for Energy Security and Net Zero)

The Energy Company Obligation (ECO) requires energy suppliers to fund energy efficiency and heating upgrades in eligible homes, with costs recovered through consumer bills. Since 2013, 4.2 million measures have been installed in 2.5 million homes. ECO4’s final impact assessment projected a positive net present value of £0.8 billion, underscoring the strong social impact and economic value of ECO.
