The purpose of the current capital support schemes is to offer applicants funding to support the installation of energy efficiency measures and zero emissions heating.

We recognise that our supply chains will have to grow substantially to meet the future demand for both installation and maintenance. 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.

The Home Energy Scotland (HES) Grant and Loan Scheme was launched in December 2022. The figures provided show the number of heat pump funding offers issued between this launch date and the end of August 2023.

The Home Energy Scotland Grant and Loan scheme is available to all domestic owner occupied households in Scotland, therefore data on household income and age of applicants are not collected during the application process. In the following table, the data requested has therefore been supplied for local authority area only.

The Home Energy Scotland (HES) Grant and Loan Scheme offers homeowners in Scotland a grant, interest free loan or a combination of both to support the installation of energy efficiency measures and zero direct emission heating.

Energy efficiency measures funded through the scheme must be recommended on the property’s EPC, ensuring that funding is being utilised for measures which are suitable for a property and will result in a reduction in carbon emissions.

The following table sets out the number of applications approved for energy efficiency measures and clean heating systems for the financial year 2022-23. The figures include data from the Home Energy Scotland Loan and Cashback Scheme, which operated until December 2022, and the Grant and Loan scheme which began in December 2022.

A ‘clean heating system’ refers to a ‘zero direct emissions heating system’.

Hybrid heat pumps and hybrid heat pump systems are not included in the number of clean heating systems, as these usually include a heating source which directly produces carbon emissions, although the Scottish Government only provides funding for the zero emissions element.

On behalf of the Scottish Government, Element Energy conducted analysis of the technical suitability of low-carbon heating technologies in Scottish domestic buildings. A copy of this report is available here: Scottish Government (2020). Technical Feasibility of Low Carbon Heating in Domestic Buildings, www.gov.scot/publications/technical-feasibility-low-carbon-heating-domestic-buildings-report-scottish-governments-directorate-energy-climate-change/ .

We have recently published research by ClimateXchange that considers options for a methodology to assess the suitability of whole-building heating systems and we are currently undertaking work to develop options for such a methodology for further consideration.

We will consult during 2023 on proposals for a Heat in Buildings Bill to phase out polluting heating systems in Scotland’s homes and buildings and move to clean heating systems. Any regulations introduced will be technology-neutral since different homes and buildings will require different clean heat solutions (including heat pumps, heat networks and direct electric heating systems).

Our Heat in Buildings Strategy recognises that some properties may have fewer technology options available as a result of location and property type, impact on the fabric of historic buildings and electricity grid capacity.

The cost of converting to a clean heating system is likely to vary according to property type, size and condition. We therefore have a broad range of delivery programmes to provide advice and financial support for householders related to energy efficiency and clean heating.

The Scottish Government funds Home Energy Scotland (HES), administered by Energy Saving Trust, to provide free and impartial advice on energy efficiency, renewable heating and fuel poverty support in Scotland. Within HES there are specialist renewables advisors with training on home renewables systems, home energy efficiency; and solutions for hard to treat and historic buildings. These specialists provide an in-depth service to Scottish homeowners, which can include on-site assessments.

Our Warmer Homes Scotland programme takes a bespoke, whole house approach to support those at risk of fuel poverty through installing insulation and heating measures. A retrofit assessment in accordance with PAS 2035 quality standards is prepared for each home and only where renewables or zero direct emissions heating are technically appropriate, and would not increase running costs, will we offer those to the householder. A wide range of measures is available under the programme and where renewables are not appropriate then the assessor will recommend a suitable package of insulation and/or other heating options.

We will consult before the end of the year on proposals for a Heat in Buildings Bill. Any regulations introduced will be technology-neutral since different homes and buildings will require different clean heat solutions (including heat pumps, heat networks and direct electric heating systems).

The Scottish Government remains committed to its fabric first approach, set out in our Heat in Buildings Strategy, which prioritises improving the energy efficiency of Scotland’s homes. This is critical to the heat transition, reducing demand for energy, and making homes warmer and easier to heat. However, ensuring that the fabric of a home is in good condition, and adequately repaired if required, prior to completing insulation works is important.

The following table sets out the total number of applications approved and paid for the rural uplift in each month from September 2022 to October 2023.

The rural uplift has only been included as part of the HES Grant and Loan Scheme since the launch of the Scheme in December 2022, meaning data only goes back to this date. Four applications from November 2022 received the rural uplift as these had not yet progressed to a formal offer when the rural uplift was introduced.

Payments are often made in the months following an approved application, which means that the number of applications approved in a month will not be equal to the number of applications paid in a month.
