Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an estimate of the number and proportion of installers who are registered to undertake ECO4 measures accept applications for support from park home households.

The Energy Company Obligation (ECO) scheme is a requirement placed on larger energy suppliers, and is fully focussed on supporting low income and vulnerable households in receiving energy efficiency measures.

Under ECO, suppliers/installers decide where to install measures based on property suitability and the cost-effectiveness of installing there. Government estimates that under ECO4, around 800,000 measures may be installed in around 450,000 households.

While park home households are within scope for ECO4, the Government does not become involved with the private contractual decisions of suppliers and installers, nor does it collect data on the number of accepted park home applications by these parties.
