Home-Heating Oil Prices Hit 30-Year High Amid Iran War Disruptions
Energy markets are facing a severe shock as the price of home-heating oil has surged to its highest level since 1996. Driven by global fuel supply disruptions stemming from the war in Iran, prices have spiked with unprecedented volatility, triggering widespread fuel protests and a rise in opportunistic crime across Ireland and Northern Ireland.
Record-Breaking Price Surges
According to data from the Central Statistics Office (CSO), the price of home-heating oil rose by 67.5% last month compared to February. This represents the largest month-on-month increase ever recorded by the CSO, surpassing the previous record of 58.4% seen in March 2022 following the Russian invasion of Ukraine. On an annual basis, home-heating oil prices have climbed by 63.3%.
The volatility extends beyond heating oil to other transport fuels:
- Diesel: Reached its highest level since July 2022, hitting €2.05 last month, an 18.1% increase in March and a 16.5% increase over the last 12 months.
- Petrol: Reached its highest level since August 2022, rising to €1.88, which is a 7.7% increase in March and a 5.7% increase annually.
Civil Unrest and National Sabotage
The price spikes have ignited nationwide fuel protests. Demonstrators have organized blockades and slow-moving convoys, causing significant disruption across the State. These protests have targeted critical infrastructure, including fuel depots and the State’s only oil refinery at Whitegate in Co Cork.

Taoiseach Micheál Martin has condemned the blockade of the Whitegate refinery, labeling the action an “act of national sabotage.” The situation has escalated to the point where defence forces were deployed on Thursday to manage demonstrations in Dublin, Cork and on major motorways.
The operational impact on retail fuel has been immediate. Vincent Jennings, CEO of the Convenience Stores and Newsagents Association (CSNA), reported that up to 40 forecourts were without fuel, warning that this number could reach 100 if blockades persist. Deputy Garda Commissioner Shawna Coxon has warned that those blocking critical infrastructure are breaking the law and that enforcement actions will initiate if protesters do not disperse.
The Crisis in Northern Ireland: ‘Liquid Gold’
Northern Ireland is particularly vulnerable to these price shocks due to its high dependency on oil for heating. Approximately 62% of households in Northern Ireland use oil, a figure that rises to 80% in rural areas. This dependency has turned heating oil into “liquid gold,” leading to a surge in thefts.
Criminals are reportedly monitoring tanker deliveries to identify households that have recently stocked up. These opportunistic thieves can drain a storage tank in minutes. In one instance in Limavady, County Derry, a couple was forced to vacate their home after thieves severed an oil line, filling the residence with choking fumes.
Market Drivers and Household Impact
The current crisis is primarily driven by geopolitical instability in the Middle East. The Competition and Consumer Protection Commission (CCPC) noted that at least 70% of the retail price of home-heating oil is typically driven by wholesale costs, leaving retailers with little control over the price spikes.
The impact is felt most acutely by those reliant on kerosene, which is the main heating fuel for 26% of people in Ireland. While natural gas remains the most common source (used by 33%), the sudden cost increase for oil users creates a significant financial burden for a quarter of the population.
Key Takeaways: Energy Crisis Summary
- Highest Prices since 1996: Home-heating oil has seen its largest ever monthly increase (67.5%).
- Geopolitical Trigger: Supply disruptions are linked directly to the war in Iran.
- Infrastructure Under Threat: Blockades at the Whitegate refinery and fuel depots have led to fuel shortages at forecourts.
- Crime Spike: High prices have led to increased oil theft in rural Northern Ireland, where 80% of homes rely on oil.
- Wholesale Pressure: 70% of retail costs are dictated by wholesale market fluctuations.
