Price of 900 litres of home heating oil shoots up by £175 in two weeks in Northern Ireland
The cost of home heating oil in Northern Ireland has continued to jump up for a second straight week.
A 900 litre load of the fuel now costs an average of £790 in the Province, up from £615 two weeks earlier – a difference of £175, or 29%.
It comes after a 12 consecutive weeks of falling prices before that, down from a peak of £1,089 for 900 litres on April 9.
Before the US/Israeli attack on Iran began in late February, a 900 litre load had cost £537.
In addition, the price of petrol and diesel has also begun to change direction, with each rising slightly this week after a long decline from their peaks on April 16.
All this data comes from the Consumer Council, the government body tasked with monitoring the cost of fuels.
It runs weekly surveys every Thursday to determine the average price of all three fuels across the Province.
As of this Thursday, here were the prices of smaller batches of home heating oil (with their price a fortnight ago in brackets):
• 500 litres: £446 (£347);
• 300 litres: £277 (£216).
And here is the price of petrol and diesel as of Thursday:
• Diesel: 154.8ppl (the week before it had been 154.6ppl);
• Petrol: 144.9ppl (the week before it had been 144.7ppl).
Before the war, diesel had cost 132.6ppl, and at its peak it was 188.1ppl.
As for petrol, its pre-war price was 124.8ppl, and at its peak it was 154ppl.
Raymond Gormley, head of energy policy at the Consumer Council, said home heating oil is now about 43% higher than before the war, adding: “Unfortunately, in July we have seen oil prices creeping upwards again.
“Prices had reached a four-month low up until the end of June, but since July we have seen prices rise a little bit each day.
"However, prices have jumped sharply over the past week as the energy markets reacted to the renewed US attacks on Iran.
"As tensions increase in the Middle East, oil tankers trying to navigate through the Strait of Hormuz have seen their movements curtailed.
And the Consumer Council’s Michelle Kelly, head of transport policy, said: “This is the first increase in petrol and diesel prices in several weeks, reflecting a rise in wholesale prices following tensions in the Middle East.
“Prices remain significantly higher than they were in February 2026.
"Consumers are currently paying, on average, around £8 more to fill a 40-litre tank of unleaded petrol and around £9 more for diesel, compared to prices on 26 February 2026.
“It is difficult to predict what will happen in the coming weeks, however, any notable change in petrol and diesel prices will only occur following a sustained decrease in the wholesale price."
Today the US expanded its air strike campaign against Iran by hitting more bridges, electrical equipment, and collapsing a tower at a key Iranian port.
The assault is part of US president Donald Trump’s threats to start striking infrastructure to pressure Tehran to ease its chokehold on the Strait of Hormuz.
In response, Iran has launched new missile attacks against US-allied nations in the Middle East.
Mr Trump said the US is “winning big in Iran, and you will see the fruits of that labour very, very shortly”.
