The information is published in the fifth annual summary report of the delivery of Home Energy Efficiency Programmes for Scotland (HEEPS).
More than 27,700 energy-efficiency measures were installed across the programmes, giving annual CO2 savings of 17,000 tonnes and cutting fuel bills by 拢4.6m, says the report.
Just over one third of measures installed during the year involved solid wall insulation, and almost 8,274 were other measures - the largest proportion of which was cavity wall insulation. In total, just over two thirds of measures delivered across HEEPS in 2017/18 were insulation measures with the remainder being heating.
The report says that the Scottish House Condition Survey - published on 4th December 2018 - indicates that around 613,000 households (24.9%) were in fuel poverty in Scotland in 2017. HEEPS is the Scottish government's mechanism for tackling this fuel poverty and improving the energy-efficiency of the domestic housing stock.
Most of the budget for fuel poverty and energy-efficiency programmes is directed at area based schemes, which are delivered by local authorities targeting fuel poor areas. They provide a range of insulation measures whilst focusing on harder to treat properties requiring more expensive interventions such as solid wall insulation. The budget for area based schemes for 2017/18 was 拢47m.
The second element of HEEPS in 2017/18 was Warmer Homes Scotland, which offers fabric measures, such as insulation, as well as heating measures to improve the energy-efficiency of the Scottish housing stock and to reduce fuel bills. For 2017/18 the budget was 拢27.275m.
The 2017/18 period also saw the continuation of HEEPS: Loans, which are open to all households across Scotland, helping to deliver a range of measures.
Additional grant funding for Energy Efficient Scotland pilot projects was made available in May 2017, with a budget of 拢2.5m for 2017/18.
The HEEPS programme also funds a free and impartial advice and support service to all householders in Scotland; its budget for 2017/18 was 拢10.075m.
