What UK fuel theft statistics tell us about 2026 so far

Fuel theft has been firmly on the industry radar in 2026, with rising fuel prices and reports of increasing theft making headlines across the UK. But beyond the stories and day-to-day experiences of operators, what are the latest figures actually telling us?

Looking at the data gives a clearer picture of how fuel theft is changing, where the pressure points are emerging, and what this could mean for businesses relying on diesel and other fuel supplies. With that in mind, let’s take a closer look at UK fuel theft statistics for the year so far, and explore what they reveal about the current fuel landscape.

What are the 2026 UK fuel theft statistics telling us?

If you want a quick impression of how fuel theft has developed in the UK during 2026, forecourt figures provide a useful starting point. Analysis from Forecourt Eye found that incidents of fuel taken without payment increased by 20% in the five months following the outbreak of the Iran conflict on 28 February, while the value of the stolen fuel rose by 48% over the same period.

While forecourts offer only one view of the wider picture, the figures show that fuel theft is a growing concern. But what about the fuel already sitting in commercial vehicle tanks?

Wider fuel theft

Looking beyond the forecourt gives a broader view of where fuel theft is occurring, particularly across rural businesses and commercial sites. DeterTech Crime Intelligence recorded at least 50,000 litres of fuel stolen in 44 reported UK incidents across March and April 2026. In comparison, during the same period in 2025, approximately 14,525 litres were reported stolen across 20 incidents – that represents a 120% increase in reported incidents and an increase of around 340% in the volume of fuel reported stolen.

The reported incidents covered a range of situations, from fuel stored on farms and rural sites to fuel carried by commercial vehicles. DeterTech's intelligence identified fuel tanks, bowsers, machinery and generators as targets, while modified vehicles were also being used to remove fuel from HGVs.

There’s also other evidence that commercial vehicle tanks themselves are being targeted. In May 2026, the Association of Fleet Professionals reported a small number of cases involving vehicles parked at secure depots, where fuel tanks had been drilled and emptied overnight. The incidents occurred in areas where vehicles were also being targeted for parts, although AFP stressed that this remained a limited issue rather than evidence of a wider surge in fleet fuel crime. Even so, the reports highlight that securing a vehicle in a depot does not necessarily remove the risk of fuel theft.

What does this mean for your fleet?

As we discussed in a blog earlier this year, fuel costs can have a significant impact on fleet operating budgets. The latest figures add another consideration: the fuel already sitting in your vehicles is a valuable asset, and one that needs protecting.

For fleet operators, that means looking beyond where vehicles are parked and considering how well the fuel itself is protected. Secure depots and sensible parking arrangements remain important, but they’re only part of a wider approach to improve fuel security and reduce the risk of theft. Ultimately, the 2026 figures are not about suggesting that every fleet is at immediate risk. They highlight something more practical: when every litre carries a cost, preventing fuel from being lost to theft is another part of protecting your fleet's bottom line.

For operators looking at the UK fuel theft statistics and considering where their own exposures may lie, strengthening protection at the fuel tank is a practical step to consider. One option is to add a physical barrier that makes unauthorised access to the fuel more difficult – and that’s where we come in. Our TankSafe® Optimum 9 device is designed for this purpose, using a patented float-valve mechanism to provide complete protection against fuel theft. With fuel costs continuing to put pressure on fleet budgets, this industry-leading anti-siphon device can give operators greater confidence while helping to limit avoidable losses and reduce fuel bills by 15%.
