Oil and Fuel Prices in the UK 2026

British drivers experienced one of the most dramatic fuel price shocks in over a decade during the spring of 2026, after a geopolitical crisis in the Middle East sent pump prices climbing at a pace the RAC described as “unprecedented.” Following military strikes on Iran on 28 February 2026, average UK diesel prices surged 40 pence per litre in March alone, nearly double the previous monthly record set during the early weeks of Russia’s invasion of Ukraine in 2022. By mid-April, diesel had rocketed to 192.14 pence per litre and petrol to 158.78 pence per litre, before both fuels began a steady retreat that continued into the summer.

This report lays out the most current, verified oil and petrol price statistics for the UK in 2026, sourced exclusively from the House of Commons Library, official GOV.UK weekly road fuel price statistics, and RAC Fuel Watch data. Readers will find figures on the scale of the 2026 price surge, current pump prices, historical price records, the breakdown of fuel duty and VAT, regional price variations, and the government’s fuel duty policy through 2027. Every number reflects the latest published official data, giving drivers, businesses, and policymakers a single reliable reference point on UK fuel prices today.

These figures capture a genuinely turbulent year for UK fuel prices, bookended by a violent spring surge and a notable summer correction. The trigger came on 28 February 2026, when the United States and Israel began a series of strikes on Iran, immediately disrupting global oil supply chains and sending both crude and pump prices sharply higher. Within the first three weeks of March alone, weekly data showed petrol rising 12 pence a litre and diesel jumping 25 pence a litre, a pace of increase that accelerated further as the month wore on.

By the time prices peaked, diesel had climbed from 142.38 pence per litre at the start of March to 192.14 pence per litre by mid-April, a rise the RAC’s own spokesperson described as “harder to swallow” than anything seen in over two decades of data collection, given diesel’s 40-pence monthly jump was nearly double the previous record increase of 22 pence recorded in March 2022. Petrol followed a somewhat slower but still substantial trajectory, not reaching its own peak of 158.78 pence per litre until late May, before both fuels began easing through June and July, with diesel notably posting its largest-ever monthly drop on record as prices retreated toward the mid-160s pence range, a volatility pattern that mirrors broader global energy market disruption tracked in our Global Oil Prices Statistics coverage of international crude markets during the same period.

The scale and speed of the March-to-April 2026 fuel price surge stands out even against the historically volatile backdrop of UK pump prices over the past several years. Diesel climbed from 142.15 pence per litre on 2 March to a peak of 192.14 pence per litre by mid-April, a rise of nearly 50 pence per litre in just six weeks, while petrol moved from 132.14 to 158.17 pence per litre over the same window. The RAC confirmed that diesel prices rose on 40 consecutive days before finally posting its first small dip in mid-April, an unbroken run of daily increases without precedent in the organisation’s price-tracking history dating back to 2000.

This surge also produced the widest gap between diesel and petrol prices seen in years, with the spread between the two fuels reaching 33.97 pence per litre at its peak in mid-April, more than double the typical premium diesel commands over petrol in ordinary market conditions. The scale of the March increase alone, a 40-pence single-month rise in diesel prices, nearly doubled the previous record of 22 pence set in March 2022 during the immediate aftermath of Russia’s invasion of Ukraine, underscoring just how severely the Iran conflict disrupted global oil supply chains and pushed wholesale fuel costs to levels British drivers had not experienced since the depths of the 2022 energy crisis.

As of the week commencing 13 July 2026, UK petrol prices stood at 150.53 pence per litre, a modest 0.73-pence weekly increase, while diesel eased slightly to 164.52 pence per litre, down 0.25 pence on the previous week. This left the diesel premium over petrol at 13.99 pence per litre, continuing a steady narrowing from the extreme 34-pence gap recorded at the height of the spring surge, as diesel’s sharper price swings both up and down have outpaced petrol’s comparatively steadier trajectory throughout 2026.

In practical terms for drivers, these prices translate to roughly £6.86 for a UK gallon of petrol and £7.60 for a gallon of diesel as of early July, levels the motoring press has noted have not been seen since the summer of 2022, at the height of the previous energy crisis. Regional variation remains a persistent feature of the UK fuel market: October 2025 data placed Dundee, Scotland, as the cheapest city in the country for petrol at £1.26 per litre, while Ashfield, Nottinghamshire, recorded the lowest diesel price at £1.33 per litre, reflecting the UK’s broader pattern in which Scotland, Wales, and Northern Ireland typically post lower average pump prices than England, a regional cost dynamic closely tied to the wider household budget pressures explored in our Cost of Living Statistics in UK coverage.

While the 2026 surge was severe, it did not surpass the UK’s all-time fuel price records, which remain from the depths of the 2022 energy crisis, when petrol and diesel peaked at 191.6 and 199.2 pence per litre respectively on 4 July 2022. Even so, the 2026 diesel peak of 192.14 pence per litre came remarkably close to that historic high, and represented the second-highest diesel price ever recorded in the UK’s modern price-tracking history, underscoring just how severe the Iran-conflict-driven spike truly was relative to the broader post-2022 price environment.

The House of Commons Library’s own analysis notes that prices had been relatively stable in the roughly eighteen months prior to the 2026 surge, hovering around 135 pence per litre for petrol and 143 pence per litre for diesel between summer 2025 and early 2026, making the speed and scale of the subsequent spike all the more disruptive for household and business budgets. Notably, the current fuel duty rate of 52.95 pence per litre, unchanged since the 5-pence cut introduced in March 2022, remains the lowest cash-terms rate since March 2009 and the lowest real-terms rate since March 1993, meaning that despite eye-watering pump prices, the tax component of the price has actually been at a multi-decade low throughout the very period when at-the-pump costs spiked most dramatically.

Fuel Duty, VAT, and Tax Breakdown of UK Pump Prices

Taxation remains the single largest component of every litre of fuel sold in the UK, with fuel duty and VAT combined accounting for roughly 55% to 60% of the total pump price under current conditions. Fuel duty itself has sat at 52.95 pence per litre since the 5-pence cut introduced on 23 March 2022 in response to the initial fuel price shock following Russia’s invasion of Ukraine, a reduction from the 57.95 pence per litre rate that had been frozen for 11 consecutive years prior to that cut. On top of duty, VAT at 20% is applied to the entire pump price, including the duty itself, a structure critics have described as effectively a “tax on tax.”

This temporary duty cut, however, is now scheduled for a phased reversal beginning later in 2026. Under the current government timetable, duty is set to rise by 1 pence per litre in September 2026, followed by a further 2-pence increase in December 2026, before a final 2-pence rise in March 2027 returns the rate fully to its pre-2022 level of 57.95 pence per litre. Separately, some reporting has indicated the Prime Minister extended the freeze through the end of 2026 before duty begins rising from January 2027, with rises of 3 pence in January and a further 2 pence in March 2027, alongside a commitment to begin indexing duty to inflation annually from April 2027, meaning UK drivers should expect the tax component of pump prices to climb steadily over the following twelve to eighteen months regardless of how wholesale crude prices themselves behave.

Fuel prices vary considerably across different parts of the United Kingdom, with Northern Ireland generally recording the lowest average prices of any UK region, while Scotland and Wales also typically sit below the England-dominated national average. As of the most recent regional breakdown from October 2025, Dundee held the distinction of the UK’s cheapest city for petrol at £1.26 per litre, while Ashfield in Nottinghamshire offered the lowest diesel price nationally at £1.33 per litre, illustrating that the cheapest fuel is not always concentrated in a single region but can emerge from specific local competitive dynamics.

Retailer type also plays a significant role in price variation, with the UK’s major supermarket chains, Asda, Morrisons, Sainsbury’s, and Tesco, consistently offering some of the most competitive fuel prices nationally, having been among the first retailers to pass on the government’s 2022 duty cut in full to customers. The scale of possible price variation even within a small geographic area can be substantial: an RAC investigation for ITV’s Tonight programme in March 2024 documented a 27-pence-per-litre difference between two filling stations situated just a short drive apart, a gap illustrating why the RAC continues to recommend tools like its myRAC app’s Fuel Finder feature to help drivers identify genuinely competitive local pricing rather than assuming all nearby stations charge similar rates.

The root cause of the UK’s 2026 fuel price surge traces directly to international events well beyond Britain’s own energy market. When the United States and Israel began a series of military strikes on Iran on 28 February 2026, the resulting conflict immediately disrupted global crude oil supply chains, sending both benchmark oil prices and refined petroleum product costs sharply higher within days. UK pump prices responded almost immediately, with weekly government data showing petrol rising 12 pence per litre and diesel climbing 25 pence per litre in just the first three weeks of March alone, before the increases accelerated further into April.

This episode underscores how directly exposed UK fuel prices remain to international geopolitical shocks, given the country’s continued reliance on imported crude oil and, more broadly, its dependence on liquefied natural gas (LNG) for roughly a third of its total energy supply, much of which transits through or near regions affected by exactly this kind of Middle East conflict. As global oil markets gradually stabilised through the late spring and into summer, UK pump prices followed suit, retreating from their April and May peaks even as the underlying fuel duty tax burden remains scheduled to rise through the remainder of 2026 and into 2027, meaning British drivers face a genuinely mixed outlook: near-term relief from the worst of the geopolitically-driven price spike, offset by a structural increase in taxation already built into government policy for the months ahead, a fiscal dynamic that connects directly to the broader public finance pressures tracked in our Budget Deficit Statistics in UK coverage of government spending and revenue priorities.
