How global heating oil and diesel shortages could push up UK wholesale energy costs this winter

Global distillate fuel production drops and low US inventories may raise wholesale prices for UK heating oil and diesel users. Here’s how the market link works.

How global heating oil and diesel shortages could push up UK wholesale energy costs this winter

If you run a café, takeaway or small shop that relies on heating oil, diesel for delivery vans or backup generators, this winter’s global distillate fuel market could nudge your wholesale energy costs higher. Recent data from the U.S. Energy Information Administration (EIA) shows that global distillate fuel production has fallen, inventories are low, and prices are rising—trends that may ripple into UK wholesale markets and supplier hedging strategies.

What happened

Global distillate fuel production—including heating oil and diesel—has dropped because refineries worldwide are processing less crude oil. The EIA reports that reduced refining activity has tightened supply, pushing international distillate prices up. At the same time, the U.S. is exporting 20% more distillate fuel to Europe in 2026 compared to 2025, as European buyers seek alternatives to constrained local supply.

U.S. distillate fuel stocks are expected to be 11% below the five-year average in the final quarter of 2026. The EIA attributes this to two pressures: higher export demand (especially to Europe) and more costly imports into the U.S. These low inventories increase the risk of price volatility, particularly if cold weather or supply disruptions occur.

In the U.S., heating oil prices are forecast to rise by 34% this winter compared to last year, though warmer temperatures in the Northeast may partly offset the increase. Electricity expenditures for U.S. households are also expected to rise by 4% on average, driven by higher prices rather than colder weather.

How the market link works

UK wholesale energy prices for heating oil, diesel and even electricity are influenced by global distillate fuel markets in several ways:

  1. Shared supply chains: The UK imports distillate fuels, including heating oil and diesel, from global markets. When international prices rise due to lower production or higher demand (e.g., U.S. exports to Europe), UK importers face higher costs. These costs are typically passed on to wholesalers and, eventually, to business customers.

  2. Storage and inventory risk: Low global inventories mean suppliers have less buffer to absorb price shocks. If a cold snap in Europe or Asia increases demand, UK wholesalers may compete for limited supply, pushing prices up further. This is a risk signal for businesses reliant on heating oil or diesel, as it increases the likelihood of price spikes.

  3. Supplier hedging strategies: Energy suppliers often buy fuel in advance (hedging) to lock in prices for their customers. If global distillate prices are rising, suppliers may hedge at higher rates, which could be reflected in future contract renewal offers or variable tariffs for businesses.

  4. Indirect impact on electricity: While the UK’s electricity prices are primarily driven by gas and renewable generation, distillate fuels are used in backup power plants and industrial processes. If global distillate prices rise, the cost of running these plants could increase, indirectly influencing wholesale electricity prices.

What this does not prove

The EIA data does not predict a specific price rise for UK businesses. Local factors—such as UK storage levels, weather, and domestic refining capacity—will also shape wholesale and retail prices. The data also does not guarantee that suppliers will change their hedging strategies or pass on costs immediately. Instead, it highlights a global market trend that could contribute to higher wholesale costs or increased price volatility.

What owners can monitor or check now

  • Wholesale price trends: Track UK wholesale heating oil or diesel prices through industry reports (e.g., Argus Media or Platts). Rising prices may signal tighter supply.
  • Supplier communications: Watch for updates from your energy supplier about market conditions or changes to hedging strategies, particularly if you’re approaching a contract renewal.
  • Weather forecasts: Cold snaps in Europe or Asia can increase global demand for distillate fuels, tightening supply and pushing prices up. Monitor long-range forecasts from the Met Office.
