Written questions by Ferguson.

Whether his Department has plans to align the commencement of measures in the Warm Homes Plan with the cessation of ECO4 funding.

The Warm Homes Plan represents the biggest ever public investment in home upgrades. At the Autumn Budget on 26th November, the Chancellor announced an additional £1.5 billion of funding for the Warm Homes Plan, bringing total capital investment to almost £15 billion. This exceeds our manifesto commitment of £13.2 billion and is a major step forward in the government’s plans to upgrade up to 5 million homes over this Parliament and cut energy bills for good.

Whether the Warm Homes Plan will provide energy efficiency measures to vulnerable households previously provided under the ECO4 scheme.

The extra £1.5 billion allocated to the Warm Homes Plan through the budget will be spent on low income households. Details on allocation will be set out in the Warm Homes Plan.

Whether transitional support will be provided to energy efficiency installation and associated businesses.

The government consulted on an extension to ECO4 earlier this year. DESNZ Ministers have now agreed to a 9-month extension to end December 2026; however, this is subject to cross-government and Parliamentary approval. An extension would support the remediation process and allow for completion of any outstanding obligations. However, it would not be supported by funding or increased targets.

What steps he is taking to ensure continuity between ECO4 funding and Warm Homes Plan measures in the case of ongoing works over the transition period.

When his Department plans to publish the Warm Homes Plan in full.

The Government is working across departments on a comprehensive Warm Homes Plan to cut energy bills, strengthen energy security and reduce emissions. The Plan will accelerate the installation of efficient technologies such as heat pumps, heat networks, solar, home batteries and insulation, upgrading millions of homes this Parliament. We have committed almost £15 billion of investment to deliver this ambition. Further details, including funding allocations and delivery pathways, will be published soon.

What steps his Department has taken to ensure that households impacted by measures in the ECO4 scheme will be impacted by the Warm Homes Plan.

The Government will ensure that lessons learned from the current ECO4 and Great British Insulation Scheme are taken forward through delivery of the Warm Homes Plan.

The government has made clear that it is committed to reform of the consumer protection system and, through the Warm Homes Plan, we will outline our offer for households to confidently and safely take up measures like solar panels, heat pumps, home batteries and insulation, helping them save money on their bills and benefit from cleaner, cheaper heating.

What steps his Department plans to take to protect consumers if their Radio Teleswitch Service meters are not switched to smart meters by 30 June 2025.

The Government has made clear to industry that suppliers must fulfil their obligations to customers and must drive up the rate of Radio Teleswitch (RTS) meter replacements. As part of the RTS Taskforce we are doing all that we can to protect consumers from any negative impacts, and make sure that the carefully managed phase out process of RTS, which starts from 30 June, is as smooth as possible for consumers.

What information his Department holds on the number of households that needed to switch from Radio Teleswitch Service meters to smart meters in Glasgow West constituency on 30 May 2025.

The Radio Teleswitch Service (RTS), and the activity to replace it, is industry owned and led. Government and Ofgem have been working closely with the RTS Taskforce in recent months to urgently increase the rate of replacements.I am meeting with Energy UK and Ofgem on a fortnightly basis to ensure the phase out process is planned effectively and consumers are appropriately protected.
