Over 1.5 million UK homes rely on heating oil, with the majority located in rural and off-grid areas where access to the gas grid is limited or non-existent. According to government and industry estimates, around 4 million properties in the UK are off the gas grid, with a significant proportion dependent on oil as a primary heating source, particularly across Scotland, the South West and parts of the North of England.
Rising oil prices linked to escalating tensions in the Middle East are now feeding directly into this system, exposing a structural vulnerability in how large parts of rural Britain heat homes and run public buildings. Early signs of pressure are already emerging in the Shetland Islands, where increases in heating oil costs are affecting households alongside public sector estates including schools, care settings and local authority buildings.
SaveMoneyCutCarbon, the UK’s largest integrated decarbonisation delivery platform, warns that this reflects a broader national exposure rather than a localised issue. Oil remains embedded not just in heating, but across transport, logistics, agriculture, construction and backup power, meaning price shocks cascade through both household costs and operating margins across rural economies.
The UK’s reliance on oil is compounded by the nature of its building stock. In many rural regions, older and listed properties cannot easily transition to alternative heating systems, locking in oil dependency and limiting short-term flexibility. This creates a direct link between global commodity markets and domestic cost pressures, particularly during periods of geopolitical instability.
Buildings sit at the centre of this exposure. Heating accounts for a substantial share of energy use, and where oil-fired systems remain in place, cost increases are immediate. Public sector estates face the same dynamic, with rising uncertainty around energy budgets and long-term planning as volatility persists.
Mark Sait, chief executive of SaveMoneyCutCarbon, said: “The UK economy remains structurally exposed to oil, particularly across rural and off-grid areas where alternatives are constrained by infrastructure and building limitations. When global oil prices move, that impact is felt quickly across heating costs, supply chains and core operating expenses. This is not a short-term fluctuation, it highlights a deeper dependency that continues to shape cost pressures across the economy.”
SaveMoneyCutCarbon says the current volatility reinforces the need to recognise how widely oil is still used across UK infrastructure. While urban areas have progressed more quickly towards electrification, rural regions continue to face structural barriers including upfront costs, grid constraints and property limitations. The result is an uneven energy landscape, where exposure to global oil markets remains disproportionately concentrated in rural Britain.
