Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the effectiveness of his Department's marketing campaign on heat pumps; and what the total cost was of (a) that campaign and (b) the associated photo shoot at Muncaster Castle.

The Department for Energy Security and Net Zero intends to publish information on campaign spend within the DESNZ annual report and accounts 2024 to 2025, which is expected to be published later this year on GOV.UK.

We will conduct a full evaluation of the Department’s activities to promote heat pumps and the Boiler Upgrade Scheme in due course. Control of advertising, marketing and communications (AMC) expenditure ensures that, where taxpayer money is being spent on government communications, it is cost-effective, coordinated and reflects functional standards and professional best practices.
