Petrol is cheaper than it was a month ago, and for many UK drivers that matters more than any headline about oil traders or exchange rates. On Tuesday, February 3, 2026, the national picture is broadly one of easing pump prices, with unleaded sitting around the low 132p-per-litre range and diesel hovering near 141p per litre. That drop is now large enough to feel on a full fill-up, especially for families doing school runs, commuters clocking motorway miles, and small businesses that can’t dodge fuel costs.
The simplest way to think about “where it’s cheapest” is this: the lowest prices tend to cluster where competition is fiercest and margins are thinnest. That most often means supermarket forecourts and high-volume stations on busy local routes, not the convenience stops that trade on speed and location. If you’ve ever paid more simply because you were already on the slip road, you already know the pattern.
Today’s reality at the pumps
Recent national tracking puts average unleaded at about 131.91p per litre, with diesel around 140.97p per litre. For a typical 55-litre family car, that works out to roughly £72.55 to fill a petrol tank and about £77.53 for diesel. Even better for drivers: petrol at this level is a genuine rewind, with prices last seen in the summer of 2021.
Where drivers usually pay the least
| Cheapest spots | Why they’re cheaper |
|---|---|
| Supermarket forecourts | High volume, price wars, and tighter margins to pull shoppers onto the site. |
| Busy local main roads | Competitors nearby keep prices honest, especially when stations can see each other’s boards. |
| Larger independents in commuter towns | Some compete aggressively against supermarkets to win regular weekday traffic. |
| Places you usually overpay | Motorway services and “last stop” stations before long stretches often charge a premium for convenience. |
A new tool is changing the hunt for cheap fuel
From this week, a national fuel price transparency push is designed to make comparisons less of a guessing game. Stations are expected to publish price changes quickly, creating a clearer picture of who is undercutting whom. For drivers, that means the “cheapest within a short detour” becomes easier to spot, not just the cheapest station you happened to pass.
If you want an official benchmark that tracks how prices move week to week, the UK’s published figures are available via the government’s weekly road fuel prices series, which helps put everyday pump prices in context.
Why petrol prices are falling right now
The drop at UK pumps has been driven by a calmer wholesale backdrop. Oil dipped below the $60-a-barrel mark in early January, easing the cost of refined fuel that retailers buy before it ever reaches a forecourt. When that wholesale cost slides and stays lower long enough, pump prices usually follow. The “usually” matters, because the pace of pass-through depends on competition, local pricing tactics, and how much margin retailers choose to take.
Taxes are the other reason UK fuel rarely feels “cheap,” even when oil is soft. A sizeable portion of what you pay is baked in through fuel duty and VAT, which means pump prices can only fall so far before the tax share becomes dominant. That’s why even a meaningful decline in wholesale costs can show up as a modest change in pence per litre at the nozzle.
So where should drivers look today
If your goal is the lowest price, start with supermarket forecourts and high-competition clusters where multiple stations sit within a couple of miles. If you’re travelling, try to fill up before you hit motorway service areas, where convenience premiums are most common. And if you’re seeing a surprisingly high price in your area, it’s worth checking a nearby town or a route that runs parallel to major roads, where forecourts often price more aggressively to win repeat custom.
The wider story is that the UK is back in a band of petrol prices that many drivers haven’t seen for years. That doesn’t solve the cost-of-living squeeze, but it does change the maths of weekly travel. For households and small firms alike, the difference between paying “whatever is on the board” and paying the cheapest nearby rate adds up quietly, litre after litre, week after week.
