Home Heating Oil
The home heating oil (HHO) market in Northern Ireland (NI) is not regulated. This is because there are many suppliers and therefore there is competition in the market. There are currently around 300 suppliers in NI.

How many homes use HHO?
Around 70 per cent of households (495,560) in Northern Ireland use oil to heat their homes.
What affects the price of HHO?
HHO prices vary depending on market conditions. This includes changes to the price of crude oil, the cost to refine the product, the cost of marketing and distribution, the profits of refiners and wholesalers, the time of year (the price can be more expensive in the winter as demand is high during cold weather) and competition from suppliers across the region. Prices are quoted per litre of oil.
What does the Consumer Council do in relation to HHO?
The Consumer Council contacts HHO suppliers across Northern Ireland three times each week to check prices and publishes it online. Consumers can use this information as a benchmark to see how much the average cost of oil is in their region. Click here to visit our HHO price survey.
