Will there be a winter heating oil shortage in the UK?
Every winter brings questions about whether heating oil and diesel supplies will be sufficient to meet demand. Those concerns are particularly understandable this year, following significant disruption and volatility across global oil markets.
However, there’s an important distinction between a nationwide fuel shortage and a period of tighter supply, higher demand, or longer delivery times. For households, farms, and businesses that rely on fuel deliveries, the latter can still cause practical problems, particularly if a tank is already running low.
The sensible approach is therefore to plan ahead, rather than wait until fuel is urgently needed.
Is there a diesel shortage in the UK?
The answer depends on what is meant by ‘shortage’. A genuine nationwide shortage would mean that sufficient fuel couldn’t be obtained to meet demand. A tighter market is different. Fuel can still be available, but there may be less flexibility in the supply chain, greater price volatility, or longer delivery times during periods of particularly high demand.
The UK is part of a global fuel market, so disruption to international oil production, refining, or shipping can affect both availability and price. The International Energy Agency (IEA) has described the disruption around the Strait of Hormuz in 2026 as an exceptionally significant shock to global oil supply. But this doesn’t mean an international disruption automatically results in UK forecourts or heating oil tanks running dry. The UK has its own refining, import, storage, distribution, and delivery infrastructure. For individual fuel customers, the more useful question is whether fuel could become harder to obtain quickly when it’s needed.
Heating oil shortage (UK-specific) – what could cause problems?
Several factors can put pressure on heating oil supplies at the same time. International disruption can affect the availability of crude oil or refined products. Shipping constraints can make some supplies more difficult to move, while refinery maintenance or outages can reduce available product. At the same time, colder weather can increase demand.
There’s also the delivery network itself to consider. Heating oil needs to be sourced, transported, stored, and delivered to individual homes and businesses. If many customers place orders at roughly the same time, delivery capacity can become stretched.
As a result, a customer can potentially experience a longer wait for delivery even when fuel remains available nationally. Keeping a sensible amount of fuel in reserve can provide more flexibility if delivery times change or demand increases.
Could winter demand put additional pressure on supplies?
Yes. Winter naturally changes the pattern of fuel demand. Households generally use more heating oil when temperatures fall, while farms and businesses may have increased requirements for heating, machinery, generators, or other operations. If colder weather coincides with an already tight wholesale market, demand can increase quickly.
But we’d like to be clear that this doesn’t mean customers should fill their tanks unnecessarily. Buying more fuel than you need can itself contribute to a sudden increase in demand. A more practical approach is to understand your normal rate of consumption and arrange your next delivery before your supply becomes critically low.
Red diesel shortage – what does it mean for farms and businesses?
For agricultural and commercial customers, concerns about a red diesel shortage can be particularly important because fuel is often essential to day-to-day operations. Farms may depend on gas oil for tractors, combines, telehandlers, generators, heating, and other equipment. Businesses may need diesel for vehicles, plant, generators, or machinery.
Running out can therefore cause problems beyond the cost of the fuel itself. Machinery may be unable to operate, deliveries can be disrupted, and work may have to stop unexpectedly.
The practical response is similar to that for domestic heating oil: monitor usage and avoid waiting until the tank is almost empty before arranging the next delivery.
Is a heating oil shortage the same as a heating oil price increase?
While fuel availability and fuel price are connected, they’re not the same thing. A market can have sufficient physical fuel while prices remain high because the cost of sourcing and replacing that fuel has increased. Equally, a temporary supply disruption can cause prices to rise without resulting in a prolonged nationwide shortage.
The 2026 heating oil market demonstrates this distinction. The Competition and Markets Authority (CMA) found that average UK heating oil prices rose from 64ppl in February to 104ppl in March 2026, peaked at 123ppl in April, and then fell by 15% in May to 104ppl.
These figures illustrate why “Will heating oil prices go down?” and “Will there be a heating oil shortage?” are separate questions. Prices can rise or fall without there necessarily being a nationwide shortage of physical fuel.
UK diesel price forecast – what can customers expect?
Any UK diesel price forecast needs to be treated with caution. Diesel prices are influenced by international crude and refined-product markets, supply and demand, shipping conditions, refinery capacity, inventories, currency movements, and geopolitical developments.
A forecast can therefore indicate the risks facing the market, but it cannot reliably tell an individual customer what their next delivery will cost.
The same principle applies to heating oil. Rather than trying to predict an exact price several months ahead, it is more useful to consider how much fuel is likely to be needed and how much flexibility there is if prices or delivery conditions change.
For farms and businesses, this could mean reviewing previous winter usage and planning deliveries around operational requirements. For households, it means keeping an eye on the tank and avoiding a situation where an urgent delivery becomes necessary.
Will heating oil prices go down?
Heating oil prices could fall if supply concerns ease, production or shipping recover, inventories improve, or demand weakens. The 2026 market has already demonstrated how quickly prices can move in both directions, with the CMA recording a 15% fall in average UK heating oil prices in May following the sharp increases seen earlier in the year.
However, there is no reliable timetable for when prices might fall, or any guarantee that they will. For customers who need fuel before winter, waiting for a lower price carries a degree of risk. Prices could fall, but demand could also increase or market conditions could change before the next delivery is needed.
Will diesel prices go down?
The same applies to diesel. Prices may decrease, particularly if international supply conditions improve. However, the factors that cause prices to fall can change just as quickly as those that caused them to rise.
For a business that relies on diesel to operate, the cost of running out of fuel or delaying work may be considerably greater than the difference between today’s price and a hoped-for lower price. For essential fuel users, security of supply and operational continuity therefore need to be considered alongside price.
How to prepare for winter without panic-buying
Preparing early does not mean buying more fuel than you need. It means understanding your normal consumption and avoiding unnecessary exposure to last-minute demand.
Start by looking at previous winter usage. This can help households, farms, and businesses identify when they usually need to reorder. It is also worth avoiding a critically low tank, as leaving a sensible amount in reserve provides more flexibility if temperatures fall suddenly or delivery times change.
For domestic customers, CosyConnect can monitor heating oil levels remotely and automatically trigger an order when the tank reaches an agreed level. For farms and commercial customers, TankPal can provide remote monitoring and support automatic reordering across operations.
If your winter requirements are unusual, it can also be useful to discuss them with your fuel supplier in advance. This might include a business expecting higher fuel usage, a farm operating multiple sites, or a household whose heating requirements have changed.
What if I am worried about running out?
If your tank is already getting low, don’t wait until it becomes an emergency. Check the current level, consider how quickly you have been using fuel, and arrange your next delivery.
If fuel is running down faster than expected, it’s worth considering whether there’s another reason. For heating oil customers, boiler servicing, heating controls, insulation, and tank condition can all affect fuel use. For farms and businesses, unusually high consumption may warrant checking vehicles, machinery, generators, heating systems, or the fuel-storage system.
Plan ahead rather than trying to predict the market
Nobody can guarantee exactly what will happen to fuel prices or supply over the winter. And by the same token, there’s no need to fill your tank unnecessarily or try to identify the exact day when prices will be lowest.
A more practical approach is to understand normal consumption, maintain equipment, monitor fuel levels, and arrange deliveries before supplies become critically low.
For households, farms, and businesses that depend on fuel, being proactive means making those arrangements while there is still flexibility around delivery timing.
