U.S.-Iran Conflict Drives Global Winter Heating Cost Surges

Global energy prices are rising sharply as conflict between the United States of America and Iran disrupts oil markets. Brent Crude prices climbed from approximately $72 to over $100 per barrel, reaching a four-month high of $108 following a drone strike on a Saudi Arabian pipeline. Shipping through the Strait of Hormuz remains limited, further tightening supply.

In the United States, the National Energy Assistance Directors Association projects that households will spend an average of $1,030 on home heating this winter, a nearly 9% increase over last year. Heating oil users in the Northeast face the steepest climb, with costs expected to surge by 31.3% to an average of nearly $2,300. These increases are attributed to the geopolitical conflict, inflation, and rising energy demand from artificial intelligence data centers. The association is urging the federal government to increase funding for the Low Income Home Energy Assistance Program.

Similar pressures are hitting Northern Ireland, where two-thirds of households rely on unregulated home heating oil. The average price for 500 litres rose nearly 10% in one week to £542, roughly double the price from September 2025. In response, the Northern Ireland Executive launched a £100 oil voucher scheme for lower-income residents, while electricity supplier Share Energy announced a nearly 13% price increase for October.
