Scottish Islands Data Overview (2025)
The Scottish Islands Data Dashboard has been updated following a review of available data. This report summarises the findings. It highlights changes between data available in 2025 and data first collated in 2023 and gives an overview of longer term trends in Scotland's Islands.
8 Fuel Poverty
Scottish island residents are generally more likely to face fuel poverty than the average Scottish resident. Island and rural local authorities generally had the highest proportion of the least energy efficient dwellings. Additionally, almost two-thirds (55%) of rural dwellings are not connected to the gas grid and therefore rely on more expensive heating fuel such as electricity and oil.
The Fuel Poverty (Targets, Definition and Strategy) (Scotland) Act 2019 defines a household as being in fuel poverty "if, in order to maintain a satisfactory heating regime, total fuel costs necessary for the home are more than 10% of the household’s adjusted net income (i.e. after housing costs), and if after deducting those fuel costs, benefits received for a care need or disability and childcare costs, the household’s remaining adjusted net income is insufficient to maintain an acceptable standard of living. The remaining adjusted net income must be at least 90% of the UK Minimum Income Standard to be considered an acceptable standard of living with an additional amount added for households in remote rural, remote small town and island areas."
Rates of fuel poverty are generally higher in the island local authorities, with around a third of residents experiencing fuel poverty in Argyll and Bute (32%), Highland (33%), Orkney Islands (31%) and Shetland Islands (31%) councils and as many as 40% in Na h-Eilean Siar, while the average for Scotland is 24% on average between 2017 and 2019.

It was not possible to update the islands-level fuel poverty data in 2025 due to low sample sizes.[16]
