Tens of thousands of rural homes could be facing up-front energy costs of more than £30,000 to meet the SNP-Greens’ mandate for all buildings to be energy-efficient by 2025.
Residents in areas such as the North East and Highlands and Islands living in off-gas grid properties have only three years to meet the target of having electric heating systems installed.
Patrick Harvie, minister for zero carbon buildings, wants more sustainable options, such as heat pumps, installed to replace fossil fuel alternatives.
But in response to a parliamentary question from Scottish Conservative MSP Liam Kerr, the Green MSP admitted that around 40,000 countryside homes – nearly a quarter of Scotland’s 170,000 off-grid properties – were not suitable for the installation of air source heat pumps.
And according to research by the trade association Liquid Gas UK, forcing these homes to upgrade to greener electric systems could cost homeowners up to £32,000.
The SNP-Green coalition is yet to set out what alternatives will be available for off-grid homes who will be compelled by law to move away from traditional heating systems.
Scottish Conservative shadow secretary for net zero, energy and transport Liam Kerr MSP said: “The fact that tens of thousands of rural homes risk being left behind and exposed tells you everything you need to know about this SNP-Green government.
“It continually obsesses about the central belt while leaving the rest of Scotland in the lurch.
“In announcing these plans, the Scottish Government didn’t stop to think about the impact on tens of thousands of people living off the gas grid.
“Now it risks implementing a policy without giving any consideration to how the people living in these homes will cope.
“Given the timescales involved, ministers must urgently set out alternatives for off-grid homes to meet the targets set down by government without being hit in the pocket or inconvenienced.
“Life can already be difficult for communities in these areas – the Scottish Government should not be seeking to make it even harder.”

Liam Kerr (North East Scotland) (Scottish Conservative and Unionist Party): To ask the Scottish Government what analysis it has undertaken to identify how many off-gas-grid homes will not be suitable for the installation of an air source heat pump, and how many properties fall into this category.
S6W-11868
Patrick Harvie: On behalf of the Scottish Government, Element Energy conducted analysis of the technical suitability of low-carbon heating technologies in Scottish domestic buildings, which included Air Source Heat Pumps (ASHPs) in off-gas-grid areas. A copy of this report is available below.
Scottish Government (2020). Technical Feasibility of Low Carbon Heating in Domestic Buildings. URL: https://www.gov.scot/publications/technical-feasibility-low-carbon-heating-domestic-buildings-report-scottish-governments-directorate-energy-climate-change/
The research concluded that, where homes were able to adopt the energy efficiency improvements required to reach EPC C, the number technically unsuitable for an ASHP would sit around 39,500 to 40,400. This is out of a total of around 170,000 off-gas-grid homes using high-emissions fuels. The underlying data is not published. For the minority of properties where ASHPs may not be viable, alternative options under current technology include air-to-air heat pumps, other electric heating or bioenergy from sustainable sources. We continue to review which technologies may be considered as zero direct emissions.
The Scottish Government announced its energy efficiency plans for homes last year: https://www.heraldscotland.com/politics/19632971.homes-scotland-meet-energy-standards-2025-despite-33bn-costs/
Research by Liquid Gas UK, the Trade Association for renewable liquid gases and LPG in the UK, suggests the cost of off-grid homes complying with these regulations could be up to £32,000 (link, and link, p6)
