Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what assessment they have made of the whole life net carbon savings which will be forfeited as a result of removing the requirement for Boiler Upgrade Scheme grant applicants to comply with Energy Performance Certificate recommendations, in particular arising from (1) the need to specify an oversized heat pump if a home is not improved, and (2) the impact on the existing annual pipeline of grant applicants, many of whom would have proceeded to install in compliance with the old requirements.

Removing the insulation requirements from the Boiler Upgrade Scheme will reduce barriers to scheme participation and increase the number of property owners moving from polluting fossil fuel heating systems to low carbon heating systems.

Whilst we are empowering consumers to decide what is right for them, it remains government guidance that properties should be well insulated to save money on bills.

In addition, we will continue to mandate that installers on the scheme are MCS certified to ensure systems are appropriately designed and sized for the property and customers are provided with advice on bills.
