Five hundred litres of home heating oil is costing people in Northern Ireland an average of £435 - up from £320 just a week ago.
The Home Heating Oil Price Checker survey carried out by the Consumer Council lays bare the staggering price rises people are facing if they want to stay warm.
It shows how anyone wanting to buy just 300 litres now will have to pay around £275, while 900 litres will cost you £758. The Consumer Council points out that oil is still the dominant fuel for heating homes in Northern Ireland, with approximately 68% of households using it.
