To ask the Scottish Government what consideration it has given to the potential impact that maintenance costs may have on the longevity of green heat systems in low-income households when developing its Heat in Buildings Bill consultation.


Clean heating system maintenance costs will vary depending on factors including the type of system and usage. We are proposing a technology-neutral approach to decarbonising homes across Scotland, with homeowners able to choose the technology which is right for them. We do not expect the cost to households of maintaining a clean heating system to be significantly different from what they would pay for a polluting heating system. The estimated maintenance costs in existing homes in 2020 used by the Climate Change Committee Sixth Carbon Budget, and developed with latest available evidence and input from a range of industry stakeholders, are the same (£100 per year) for both air source heat pumps and gas boilers. Of course many low income households rent their properties through private or social landlords, and while these maintenance costs will be comparable to those living in owner occupied homes, they will typically sit with the landlord.
