What Causes Fuel Price Spikes in Winter? Understanding Seasonal Price Volatility
Winter fuel price spikes are a predictable yet painful reality for businesses across the UK. Understanding what drives these seasonal increases can help you prepare—and protect your budget before prices surge. Here’s what causes heating oil, diesel, and other fuel costs to climb during the colder months.
The Primary Drivers of Winter Fuel Price Increases?
1. Surge in Heating Demand
Winter’s arrival triggers massive increases in heating fuel consumption across residential, commercial, and industrial sectors. As temperatures drop:
- Households switch on oil-fired heating systems
- Commercial properties increase heating
- Industrial facilities require more process heating
- Agricultural operations need heating for livestock and crop storage
This spike in demand across all sectors creates supply pressure, increased wholesale prices. Kerosene and Industrial Heating Oil (IHO) see the most increases, often rising by 18-28%.
2. Requirements for Cold Weather Performance
Fuel suppliers must adjust diesel and heating oil formulations for winter conditions. Cold weather causes standard fuel to gel or wax, potentially blocking fuel lines and filters. To prevent this:
- Refineries produce winter-grade diesel with cold flow additives
- Kerosene blends are optimized for sub-zero performance
- Additional refining processes increase production costs
These winterization processes add to the base cost of fuel, with suppliers passing these expenses to end users during the coldest months.
3. Reduced Refinery Output
Winter weather affects refinery operations and output capacity is countries like UK, Russia, and the Scandinavian countries:
- Scheduled maintenance often occurs before winter, temporarily reducing supply
- Cold weather can disrupt refinery operations and transportation in the refineries located the northern hemisphere
- Some refineries switch focus to heating oil production, reducing diesel output
- European refineries may reduce capacity during periods of lower demand
When refinery output decreases while demand increases, the supply-demand imbalance drives prices upward rapidly.
4. Transportation and Logistics Challenges
Winter weather creates delivery complications that increase costs:
- Snow and ice slow tanker deliveries and increase fuel consumption
- Road closures and difficult driving conditions limit delivery capacity
- Port disruptions can delay fuel imports
- Increased demand for delivery slots creates scheduling bottlenecks
These logistical challenges mean suppliers often charge premium prices for winter deliveries, particularly during periods of severe weather.
Global Market Factors Affecting UK Fuel Prices in 2025
OPEC+ Supply Management
Recent market analysis reveals OPEC+ oil output increased by only 30,000 barrels per day in October 2025, significantly below expectations and raising concerns that planned production increases may be largely symbolic.
Market experts suggest OPEC+ is carefully managing supply for two key reasons:
- Some member countries are struggling to increase production capacity despite quotas
- Major producers like Saudi Arabia are deliberately controlling output to prevent price crashes
Goldman Sachs has warned that OPEC+ could extend the pause in output increases from Q1 2025 further into 2026, potentially keeping global oil supplies tight and prices elevated throughout the winter heating season.
Geopolitical Tensions and Supply Disruptions
Ongoing geopolitical conflicts continue impacting fuel supply chains. Recent attacks by Ukraine on Russian oil refineries, including a drone strike on the Lukoil refinery at Nizhny Novgorod, east of Moscow, demonstrate how regional conflicts can disrupt global fuel supplies and drive price volatility.
These supply disruptions create uncertainty in wholesale markets, with traders building risk premiums into fuel prices to account for potential supply shocks.
Refined Product Market Tightness
European refined product markets are warning of pending tightness for jet fuel, gas oil, and ultra-low sulphur diesel (ULSD), with timespreads increasing meaning prompt delivery now trades at a premium compared to later delivery dates.
This market structure, known as backwardation, signals immediate supply concerns and typically results in higher prices for businesses needing fuel deliveries in the near term.
Historical Winter Fuel Price Patterns
Looking at historical data reveals consistent winter price spike patterns:
Kerosene (Heating Oil):
- Average winter increase: 18-28%
- Peak pricing typically occurs: January-February
- Largest single-day spikes: During extreme cold weather events
Diesel (DERV):
- Average winter increase: 12-20%
- Cold weather blending adds £0.03-0.05 per litre
- Supply disruptions can cause sudden 8-12% jumps
Industrial Heating Oil (IHO):
- Average winter increase: 20-30%
- Industrial demand peaks align with residential heating demand
- Process heating requirements prevent demand flexibility
These historical patterns demonstrate that winter fuel price increases are not aberrations—they’re annual certainties that businesses must plan for.
