To ask the Scottish Government when it will next review the new-build heat standard. (S6T-01924)

The new-build heat standard was approved unanimously by parliamentary committee last year, following two consultations. Local authorities are responsible for implementing it. We have engaged with them, and will continue to do so, to ensure that the regulations are implemented in the right way. That is part of the regular implementation process for new legislation, and we will continue to address any need to clarify the guidance.

The Minister might not know that rural communities across Scotland rely on wood-burning stoves to heat their homes—they did so during storm Arwen in particular. The poorly thought-out ban has been criticised by Western Isles Council, a Scottish National Party MSP and even a former Scottish Green MSP. With rural areas already suffering from population decline, why is the minister hellbent on making it even more difficult to heat new homes?

Naturally, I reject the characterisation in the member’s question. In fact, we extensively consulted rural stakeholders—including rural local authorities—in developing the regulations, over a number of years and in two formal consultation processes. I am a little surprised that the member put her question in the way that she did given that, in committee, her party colleague agreed with the unanimous support for the new-build heat standard—a measure that has been praised by the United Kingdom Climate Change Committee, which urged the UK Government to accelerate its action in that area to match our timetable.

Although a provision that refers to emergency heating was secured, which permits alternative heat sources as a back-up in off-grid situations, it does not extend to stoves. The answer that the Minister gave shows the ignorance of the SNP and Greens about the situation and about the needs of Scots who live outside the central belt.

The minister might not be banning stoves in existing homes, but the Government is consulting on doing just that. As well as reversing the ban for new builds, the minister must rule out subjecting rural communities to even harsher winters by ruling out the outright ban on wood-burning stoves. Will he commit to that?

As well as being at a slight loss as to why the member appears unwilling to engage with the fact that her party colleague supported the instrument in committee, I am disappointed that she chooses to misrepresent the Government’s position on the entirely separate consultation on the heat in buildings bill, which does not propose an outright ban on existing biomass heating systems or their installation in existing homes—in fact, it asks questions about the additional flexibility that might be required in those circumstances, specifically to deal with the experiences of rural communities that the member mentioned.

It is clear that the new-build heat standard, alongside high energy efficiency standards for new builds, is necessary to drive down carbon emissions. We are convinced that we can do that in a way that tackles Fuel Poverty for all of Scotland’s communities and stimulates the development of a clean heat supply chain in Scotland.

Given the small but often essential and traditional role that peat plays in heating some of Scotland’s most fuel-poor communities—such as those in my Constituency—will the Minister say what criteria will be set for an emergency heat system and its fuel sources in relation to the new-build heat standard? I declare an interest of a sort, as I cut peat for my own use.

The technical handbooks highlight that fixed emergency heating might be appropriate when portable solutions are not viable because of the size, complexity or heat demands of a particular building. However, the new-build heat standard is technology neutral; not only does it make a distinction between direct and zero-direct emissions heating, but it does not distinguish by fuel source.

As for situations in which peat is used for cooking, I clarify that cooking is outside the scope of the new-build heat standard, which means that fuel-burning appliances can be installed if their only purpose is cooking.

The guidance in the Government’s “Domestic Technical Handbook” says:

“emergency heating will normally be connected to the same means of heat distribution used by the normal heating system. A back-up source of electrical power would be needed to enable operation of related auxiliary systems.”

What analysis has the Scottish Government undertaken of the cost of installing all that? Given that cost and the technical issues, is there not in practice a ban? Will the Minister confirm whether the back-up source of electrical power that is now required could include a diesel generator?

As I said in my reply to Rachael Hamilton, the Government has consulted extensively and has heard from organisations, individuals and communities that have experience of the kind that Jamie Halcro Johnston refers to. We have taken account of all their responses and conducted a range of impact assessments on the measure, and we are convinced that it will achieve the objectives that I set out.

I ask Mr Halcro Johnston to recognise that, as with other aspects of our building standards system, when there is a need for discretion and the inability to apply any particular aspect of building standards, that flexibility is always there and will continue to be so.

The recent Climate Change Committee report praised the proposed heat in buildings bill as

“a template for the rest of the UK”

for decarbonising our housing stock, but it acknowledged that we will still need to ramp up the decarbonisation of our homes by a factor of 10 in the coming years if we are to have any hope of meeting our climate targets. Will the Minister confirm how the new-build heat standard will contribute to reducing our emissions from such buildings? What is the estimated emissions reduction compared with that from continuing to build new homes with direct-emissions heating?

The policy’s objective is to prevent the greenhouse gas emissions that are associated with delivering space heating, hot water and cooling in new buildings, and so to help to achieve net zero by 2045.

On the climate change plan accounting basis for emissions, over the long term, the new-build heat standard is expected to deliver cumulative savings of about 5.2 million tonnes of CO ₂ equivalent between 2024 and 2083, under central assumptions. That can be broken down as 2.3 million tonnes equivalent saving in the residential sector and 3 million tonnes equivalent in the services sector.

The member mentioned that the UK Climate Change Committee has praised our work on that. I, too, am convinced that that work will stimulate the development of the supply chain for clean heat in Scotland.

There is no escaping the fact that people in rural homes face a particular challenge in remaining warm or decarbonising their heat systems in an affordable way, and that the exceptions in legislation are necessary. Will the Minister reassure my constituents in Midlothian South, Tweeddale and Lauderdale that, through the new-build heat standard, consideration is being given to the unique needs of rural and remote homes, and that rural home owners can access additional support, including grant funding, to meet their clean heating needs?

Absolutely. We have taken seriously the concerns of rural communities and have included provision for the use of fixed emergency heating. That reflects the reality that such flexibility might be needed in some circumstances for new homes to provide emergency heat, which could include the use of wood-burning stoves.

I mentioned the extensive consultation that has taken place. North Ayrshire Council, Shetland Islands Council, Orkney Islands Council, Highlands and Islands Enterprise, Aspire Orkney and other organisations and companies working across the country, including in rural communities, took part in that, as well as in a number of separate workshops.

On grant funding, we already provide additional support to households for installing clean heating and energy efficiency measures in existing homes. For example, our home energy Scotland grants and loans have a rural uplift, which means that people in applicable areas can obtain grants of up to £9,000.

Will the Minister clarify how I am to tell my constituents who are building new houses—for example, in the area of Rothes, which is in the Shadow of a plant that burns woodchips to generate electricity, for which a grant is given—why they cannot burn wood in their wood-burning stoves?

People who currently have wood-burning stoves should be reassured that those who claim that there is an outright ban are misleading them. People who already rely on such systems can continue to do so.

In relation to new build, the UK Climate Change Committee has been clear that there are circumstances in which biomass can give us a useful contribution to reducing our carbon emissions, but that will not be the case in all circumstances. We will continue to explore the situations where that is justified, while ensuring that the homes that we build for the future are fit for the 21st century in terms of addressing climate change and particulate pollution.
