It is estimated that some 70 per cent of consumers in Northern Ireland use oil for heating, and while oil remains unregulated to the same degree as natural gas and electricity, there is an extensive network of oil distributers and suppliers which ensure that heating oil prices in Northern Ireland remain competitive with other regions.
Coal has less significance as a primary heating source, though it is used industrially, and in particular for power generation.
Liquified Petroleum Gas (LPG)
LPG is used by consumers who are not on the natural gas grid, largely as an alternative to heating oil, and for cooking.
As the natural gas network is further extended, reliance on more polluting oil and coal is likely to decrease.
