For low carbon heating, such as heat pumps, the requirement is to use Microgeneration Certification Scheme installers to access Scottish Government funded support programmes. In relation to energy efficiency measures such as insulation, to access Scottish Government funding installers should be TrustMark registered businesses. Customers accessing the HES Grant and Loan scheme who cannot locate a TrustMark registered installer may use a Green Deal certified installer.

Our Heat in Buildings Supply Chains Delivery Plan sets out practical steps that we will take to support the growth of the green heat sector. We continue to work in partnership with the sector to ensure that the appropriate support and training provision are aligned at a local level with business needs and future local demands.

This proposal is contained within the current public consultation Delivering net zero for Scotland's buildings - Heat in Buildings Bill: consultation - gov.scot (www.gov.scot) . A draft business and regulatory impact assessment has been published to support this consultation Heat in Buildings Bill consultation: business and regulatory impact assessment (partial) - gov.scot (www.gov.scot) .

The information requested is not available. The Scottish Government does not currently plan to directly procure any specific low-carbon heating or energy efficiency projects on behalf of the sector over the time periods specified. Scottish public authorities can access funding and project development support for clean heating and energy efficiency proposals through our Non-Domestic Public Sector Energy Efficiency Framework and Project Support Unit. This framework is designed to provide value for money and a standardised approach for public bodies undertaking improvements to their estate.

This is covered in the Green Heat Taskforce Part 1 Report published on 22 November 2023 – in this report Nationwide is highlighted as an example of a lender currently offering zero percent interest loans.

Colleges and universities are responsible for setting their own provision based on regional and national demand, however Energy Skills Partnership, the college sector agency in Scotland for energy transition, zero carbon transport, engineering, construction and STEM, lead a low carbon heat training network across Scotland’s colleges to share best practice.

A Business and Regulatory Impact Assessment was completed for the provisions contained within The Building (Scotland) Amendment Regulations 2023 (which introduce the New Build Heat Standard from 1 April 2024). This contains an assessment of how the Standard may impact costs associated with new homes across Scotland. The affordability of buying a home is impacted by multiple factors, including the sale price of a new building (which is determined by individual developers and takes into account a range of variables related to building construction costs and local housing markets), location and access to personal finance for buyers.
