Heating and Insulation
Installing or upgrading insulation is one of the most effective ways to improve the energy efficiency of a building. On average across 2022-2024, 58% of walls (of all types) were insulated[1] in Scotland although this ranged from 43% in Dumfries & Galloway and 44% in Aberdeen City to 79% in North Lanarkshire (Figure 1). 12% of dwellings in Aberdeen City had less than 100mm of loft insulation compared to 5% on average for Scotland, and just 1% in Angus and Falkirk (Figure 2).
The heating system is another key factor in the thermal efficiency of a dwelling. Almost all households in Scotland (96%) have a full central heating system. However, this rate is lower for Orkney Islands (81%), Na h-Eileanan Siar (85%), Highland (85%), Shetland Islands (87%), Argyll & Bute (89%) and Perth & Kinross (92%).
On average across 2022-2024, 58% of walls (of all types) were insulated in Scotland.

[1] The presence of Cavity Wall Insulation (CWI) becomes harder to detect as injection holes age, fade or are covered up. Therefore, the SHCS may underestimate the number of homes with CWI installed, despite the high quality of the physical survey.
[2] Dwellings without loft spaces are excluded.
[3] West Lothian is excluded from this figure due to small sample sizes.
