If you've filled up a diesel car recently and felt a bit of a wince at the total, you're not imagining it. Diesel prices have been climbing quickly over the past month, and in some parts of the country the pump price has already crossed the £2 a litre mark.
The numbers so far
The UK average diesel price currently sits around 193.5 pence per litre, with supermarket forecourts averaging closer to 190p. But that average masks a lot of variation, over 200 stations are already charging above £2, and hundreds more are sitting just below it at 199.9p. Data from fuel price trackers shows tens of thousands of individual price increases recorded at UK forecourts this month alone, which gives a sense of how quickly this has moved.
What's driving it
The short answer is wholesale prices. Diesel bought on the wholesale market has risen by more than 12 pence a litre this month, largely because of tension in the Middle East. Saudi Arabia's suspension of its East-West pipeline, a route that normally lets oil bypass the Strait of Hormuz, has raised concerns about supply, and that nervousness has fed straight through into the price fuel retailers pay.
Retailers themselves are also working with tighter margins than they'd like, so when wholesale costs go up, there's less room to absorb the hit before it reaches the pump. A few European governments, including Poland and Germany, are reportedly looking at ways to shield drivers from the increases, though nothing similar has been announced in the UK so far.
What it means for your wallet
If diesel keeps climbing at this rate, it's likely more forecourts will edge past the £2 threshold in the coming weeks, particularly away from the supermarkets, which tend to offer the more competitive prices. For anyone doing high mileage, whether that's a daily commute, a trade van, or a fleet of delivery vehicles, this kind of increase adds up fast.
A few practical things can help take the edge off. Fuel price comparison apps are worth having on your phone if you don't already, since the difference between the cheapest and priciest forecourt in the same town can be surprisingly large. Keeping tyres properly inflated, taking unnecessary weight out of the boot, and avoiding harsh acceleration all make a measurable difference to consumption too, small habits, but they do add up over a year of driving.
The bigger picture
Moments like this are also when a lot of people start asking whether an EV or plug-in hybrid might make more financial sense for their pattern of driving, particularly for shorter, more predictable journeys like a regular commute. It won't suit everyone, home charging access and typical mileage both matter, but with fuel costs this volatile, it's a reasonable question to ask.
If you're weighing up whether now's a sensible time to switch, or simply want a fixed, predictable monthly cost instead of watching the pumps creep up, it's a conversation we have regularly and are happy to talk through, whatever stage you're at.
