As covered in the response to S6W-07980 on 26 April 2022, the Scottish Government’s response to the Zero Emissions Social Housing Taskforce report will be published after the Scottish Local government elections. The response will address the recommendation of establishing a Housing Net Zero Technical Steering Group.

The information you have requested is publically available at the Scottish Energy Statistics Hub (shinyapps.io) taken originally from National Grid - : https://carbonintensity.org.uk/ .

In addition to that, the recent announcement of ScotWind has seen aspirations from consortia to develop up to 25GW of offshore wind capacity. This will allow us to make huge progress in further decarbonising our energy supply while securing commitments from ScotWind developers to invest at least £1bn in Scotland’s supply chain for every gigawatt of power.

The Scottish Government is clear that nuclear energy represents a bad deal for consumers and our priority continues to be to support energy efficiency, develop Scotland’s huge renewable resource and to promote storage and flexibility.

Energy Performance Certificates (EPCs) provide an assessment of the theoretical energy performance of existing and new buildings. They are generated by accredited EPC Assessors, belonging to Assessor Organisations approved by the Scottish Government. EPC assessors are required to have the necessary skills and expertise to operate the software that produces EPCs according to the standardised national methodology (SAP) developed by the UK Government and used by the Scottish Government. SAP produces indicative recommendations on how to improve the EPC score– which can include low carbon heating technologies where they are cost effective (however energy efficiency measures are currently prioritised).

The Scottish Government recognises that at present, the information presented on EPCs needs to be reformed, in line with the recommendations of the Climate Change Committee. That is why we have consulted on reforming EPCs to ensure that the metrics and recommendations align with our net zero target. This includes reforming the current energy efficiency metric, which has often incentivised fossil fuelled heating ahead of zero emissions heating solutions. We are now completing further research and intend for reformed EPCs to provide additional information on suitable zero emissions heating systems, and to provide information on the costs associated with such systems, together with energy efficiency measures, and their impacts on the costs of heating a building. As part of our wider proposed legislative programme, we will consult further on the detail of our proposals and will ensure that accredited EPC assessors have the skills needed to produce the reformed certificates.

Building owners can also seek further specialist advice on low carbon heating options beyond those generated in an EPC from a heating specialist or Building Service Engineer (represented by the professional body CIBSE). The Energy Savings Trust, Home Energy Scotland and Zero Waste Scotland provide further information and advice on low carbon heating on the behalf of the Scottish Government.

Home Energy Scotland (HES) is the main advice and referral mechanism to all Scottish Government energy efficiency schemes for homeowners. Energy Saving Trust (EST) manages the HES Service on behalf of the Scottish Government. Home Energy Scotland provide regular figures to the Scottish Government on the numbers of households they advise and the value of that advice. The Scottish Government has regular contact with EST to ensure they are meeting pre-agreed targets and maintaining the high standard of the advice that is expected of these services.

Householders making an enquiry to the HES service are dealt with by trained and qualified (SQA) advisors. HES advisers use a series of tools to ensure that the advice provided is based on the most effective measure for each householders’ specific needs. A fabric first approach is also recommended to households to ensure that heat loss is minimised before the most efficient routes to supplying the remaining residual heat requirements are considered. The analysis provided by an advisor to a householder is informed by use of a personalised Home Energy Check (HEC). The Home Energy Check is generated using bespoke energy modelling software which is used to model the thermal and other energy use characteristics of each property based on data provided by the householder. The HEC can be completed online independently by the householder via the HES website or over the telephone with an advisor.

For vulnerable householders who may require a little more support to be able to engage fully with the service or for households considering installation of low and zero carbon heating or renewable energy technologies, further specialist advice is available which can include a visit from an advisor and a bespoke onsite survey of the home. Energy modelling software is again used to model the property and to generate measures recommendations and savings figures for the householder. Through use of approved bespoke energy modelling and ensuring that advice is only delivered by suitably qualified advisors, the quality of recommendations and advice given to householders is maintained at a consistent, high level.

Energy Saving Trust operates the suite of energy advice services for home owners, SMEs and community groups on behalf of the Scottish Government.

To deliver this across Scotland the services are delivered by advice centre contractors through 5 regional advice centres and a centralised team covering out of hours. Each advice centre delivers the services to a consistent set of standards which are required by Energy Saving trust in the contract they have with the advice centre contractors.

The quality and consistency of advice provided by the programmes is directly monitored by EST. This monitoring includes the quality and relevancy of advice provided by an advisor, who are tasked with asking questions to understand each customer, their circumstances, their home/premises and their energy behaviours. This is so they can ensure advice topics they discuss are relevant and useful for each individual customer. Advisors use the same EST approved resource documents and facts and figures to ensure each topic they advise on is consistent.

The Scottish Government has regular contact to ensure EST are meeting pre-agreed targets and maintaining the high standard of the advice that is expected of these services.

We are working to deliver our Energy Strategy and Just Transition Plan (ESJTP) in the context of a fast-moving energy landscape, and will publish a draft ESJTP in autumn 2022. As our first Just Transition Plan, the ESJTP will set out what is needed to deliver a just transition for the sector, in line with the Scottish Government’s approach to just transition. This includes work to support retention and creation of access to green, fair and high-value work, as well as ensuring access to required skills and retraining opportunities. As part of this, we will identify the opportunities and risks of the transition, including those associated with transitioning jobs.

Throughout this, we remain committed to ensuring green jobs are good, green jobs, drawing on fair work principles, complying with high workplace standards and paying fair wages. That is true across the economy, but especially important in sectors vital for reaching net zero, such as the energy sector where much public investment is targeted.

The Scottish Government’s approach to zero emissions heat technologies is based on a wide range of evidence, including modelling of the suitability of different technologies across the whole Scottish housing stock, and consideration of wider energy system interactions.

We maintain an active Heat in Buildings Research Programme to identify gaps in our knowledge base and produce high-quality research to understand the challenges and solutions in the heat transition.

We have commissioned research to examine the potential of energy storage technologies to reduce running costs for households using zero emissions heat. The research considers how bill savings can be made by pairing storage technologies with onsite generation, and by storing off-peak electricity for later use. This research will be published in 2022.

I can confirm that the legal position has been considered and I refer the member to the answer to question S6W-06967 which sets out that the provisions in the Transport (Scotland) Act 2019 were subject to policy and legal scrutiny and that there is no legal issue arising from this matter.

The content of any legal advice is confidential. By long-standing convention, successive Scottish and Westminster Governments have not disclosed the content of legal advice other than in the most exceptional circumstances.

There is no change to the estimated total project cost.
