Heating Oil Prices October 2026: Should You Fill Your Tank Now?

If you heat your home with oil, the question this weekend is not simply whether 112p a litre looks expensive. It is whether you have enough oil to wait, how much a delivery would cost your household now, and how much risk you are prepared to take by delaying an order.

Fueltool's supplier average was 112.08p per litre excluding VAT on 3 October 2026, read at 03:24 UK time from 90 supplier price listings in its 1,000-1,499 litre band. BoilerJuice showed 110.03p for 1,000 litres the same morning. Those are not contradictory figures: Fueltool takes an equal-weight average of its listings, while BoilerJuice averages the lowest supplier price in each postcode district.

The timing matters because road fuel has just crossed a striking threshold. The RAC told the BBC that average diesel reached 200.01p a litre on 2 October, above £2 for the first time, while petrol averaged 174.71p. Heating oil is a different product bought through a different market, but kerosene prices have been moving amid many of the same pressures on oil and refined fuels.

On 3 October, Fueltool's standard kerosene supplier average was 112.08p a litre excluding VAT for orders in the 1,000-1,499 litre band. Fueltool says this is an average of its own supplier listings, not a survey of every supplier in the UK.

BoilerJuice's figure was lower at 110.03p a litre for 1,000 litres, also excluding 5% VAT. Its methodology is different: it averages the lowest supplier price in each postcode district. That distinction is important when you are judging whether a quote from your local distributor is reasonable.

Fueltool says its current figure is 15.6p higher than a month ago but only 0.5p higher than a week ago. The average of its thirty daily September readings was 106.8p, so today's level is also above September's monthly average.

Prices can vary by region, season, local demand and order size, according to Which?, relaying advice from the UK and Ireland Fuel Distributors Association. Your own quote can therefore sit above or below either national tracker without necessarily being wrong.

The price path this year has been anything but smooth. Fueltool's series fell as low as 63.36p on 27 February, then jumped to 79.36p on 2 March and reached 137.63p on 9 March, the highest daily figure in its past twelve months.

Prices later eased sharply, reaching 67.92p on 1 July, before climbing again through late summer and September. That history is useful because it shows why trying to pick the perfect ordering day is difficult: large changes have occurred in both directions over relatively short periods.

Today's 112.08p is below both the March peak and the 116.77p recorded on 16 September. But it is almost double Fueltool's 55.8p reading on 3 October 2025, so households comparing this autumn with last autumn are facing a very different bill.

The BBC reported on 2 October that the Iran war has severely disrupted the production and transport of wholesale oil and refined products from the region over the past seven months. Ukrainian attacks on Russian refiners have added pressure to diesel supply, while China has restricted exports of refined fuels.

The Guardian reported that UK forecourt diesel had risen 40.5% since late February, when the war on Iran began disrupting supplies of crude and refined products from the Gulf. Ole Hansen of Saxo Bank told the paper that the main strain was "no longer crude availability" but "refined product supply".

There has also been an attempt to ease the pressure. On 2 October the G7 agreed to release 100 million barrels of oil, according to the BBC, and Brent crude fell 2.5% to 99.78 US dollars a barrel that Friday after reports about reserve releases, according to the Guardian.

None of that gives a reliable household forecast for kerosene. It explains why prices have been volatile, but it does not tell you what your distributor will quote next week.

The UK government told the BBC that the country has "a diverse and resilient supply" and that there is no cause for concern about diesel shortages. More than half of the diesel bought in the UK is imported.

Fueltool's own 1,000-litre example on 3 October works out at £1,177 including 5% VAT. Domestic heating oil carries 5% VAT, according to BoilerJuice; commercial orders over 2,300 litres are charged at 20%.

BoilerJuice says typical UK homes use 1,500-2,000 litres a year, although individual consumption will obviously depend on the property, boiler use and household habits. In 2024, government figures estimated that 16% of domestic properties in Great Britain were not connected to the gas grid, rising to 24% in the South West and falling to 7% in the North East. Those figures do not say how the properties are heated.

Order size matters too. BoilerJuice says minimum deliveries in some areas are now 300 litres, and that 1,000 litres can sometimes be cheaper per litre than 500 litres depending on local suppliers.

That creates a useful middle ground. If you do not want to commit to a large fill at today's price, a 300- or 500-litre top-up may buy breathing space, provided a supplier in your area will deliver that quantity. The trade-off is that smaller or more frequent deliveries can increase your overall cost.

I would base this decision on the tank level first and the market second. If the gauge is low, order now. Running out of oil, risking sediment being drawn through the system and then having to arrange fuel under pressure is a worse position than missing a possible later price fall.

UKIFDA advises keeping at least 12 inches, roughly 300mm, of oil in the tank so sediment at the bottom is not disturbed and pulled into the pipes. That is a practical reason not to run a tank down to fumes while trying to time the market.

If you have around a quarter of a tank or more, there is more room to compare. Get three quotes and put them alongside both national trackers, remembering that 110.03p from BoilerJuice and 112.08p from Fueltool measure different things.

There is an argument for waiting, but not a safe one. Today's Fueltool figure is below the March peak and below mid-September, yet it is almost twice the level of a year ago and has risen 15.6p in a month. Which?, relaying UKIFDA advice in July, said households that are not running low could consider delaying a purchase while comparing local distributors and online prices.

A smaller top-up can split the difference. Buying 300 or 500 litres gives you more time without staking the whole tank on today's price, although repeated smaller orders can cost more overall.

Buying groups are another option. UKIFDA says oil clubs coordinate deliveries for several households, which can produce bulk-buying savings and reduce tanker trips, though you give up some flexibility over timing. Citizens Advice research from 2013 found that 97% of 49 oil clubs surveyed said they had negotiated a lower price because they were ordering for multiple households; 70% approached several suppliers, but only two were offered instalment payments.

Budget payment plans can also smooth the cash flow. UKIFDA says distributors may offer plans that spread the cost, and recommends ordering ahead rather than waiting until you are nearly empty.

A decent price is only useful if the tank, pipework and boiler are ready for winter. Before placing the order, I would work through these six checks:

While you are doing the winter jobs, it is also worth deciding when to turn the heating on, taking steps to prevent frozen pipes before the first frost, and trying a few cheap heating tweaks before winter.

UKIFDA also runs a free Cold Weather Priority scheme. If you or anyone at your address is 75 or over, ask your distributor to register you because enrolment is not automatic. It does not guarantee an immediate delivery, and you need to re-register if you change distributor, but it flags the household for priority during cold weather or tight supply.

• •Read the tank gauge and make sure you are not running below the level where sediment could be disturbed. A remote electronic level gauge can make this easier.
• •Get three local quotes and compare them with the Fueltool and BoilerJuice figures for the same day, allowing for differences in methodology and order size.
• •Inspect the tank for obvious damage or deterioration. You are responsible for it, and UKIFDA warns that spills can contaminate groundwater and foundations; bunded tanks are the most suitable type for homes.
• •Make sure the tanker can get in. UKIFDA says distributors may ask about the tank type, age, size and condition, the height of the fill point and vehicle access.
• •Check the cap or lid is secure. UKIFDA recommends a lockable cap without blocking the vent, with the distributor given the key or code; dusk-to-dawn lighting can also help with security.
• •Have the heating system maintained before winter. An annual boiler service before winter is more useful than discovering a fault just after a large delivery, and tank or boiler work should be carried out by an OFTEC-registered technician.

No. Ofgem's price cap applies to gas and electricity tariffs, while heating oil is bought from distributors on the open market and has no equivalent cap.

That distinction matters when households hear about the energy price cap for October 2026. A change to the cap does not set the price of kerosene or limit what a heating-oil distributor can quote you.

For households considering longer-term alternatives to delivered fuel, our guide to heat pump running costs compared with gas covers another part of the home-heating equation. It is a separate decision from whether to buy oil this week.
