Right, let’s not dance around it. Filling up your car in the UK has become genuinely painful over the last few months due to issues in the middle east. I pulled into my local Shell last Tuesday and watched the pump tick past £100 before I’d even got to three-quarters of a tank on my Mondeo. That’s not a rant that’s just Tuesday in Britain, unfortunately.
But here’s the thing petrol prices vary wildly, even between stations that are half a mile apart. I’ve seen a 10p-per-litre difference between two forecourts in the same town. Multiply that across a 50-litre tank, and you’re talking about a £5 saving from just being slightly smarter about where you fill up. Over a year, for someone who drives regularly, that compounds into something genuinely worth caring about.
So this is the guide I wish I’d had three years ago. I’ve spent a lot of time across different apps and websites that let you track petrol prices in the UK, and I want to walk you through the ones that actually work, what they’re good for, and where they fall short. The blog post will provide you with the best websites to find the cheapest petrol prices in the UK
Why Petrol Prices Vary So Much Across the UK
Before we get into the tools, it’s worth understanding why prices differ so drastically between stations because once you get it, the way you use these websites makes a lot more sense.
Petrol stations don’t all pay the same wholesale price for fuel. A small independent station that buys relatively modest volumes is going to pay more per litre from its supplier than a supermarket like Tesco or Asda, which is shifting millions of litres a week and has serious negotiating clout. That cost difference gets passed along to you at the pump.
Then there’s location. Motorway services are, famously, a rip-off. The same litre of unleaded that costs 145p at your local Sainsbury’s can be 165p or more at a motorway forecourt. They know you’re captive you’re low on fuel, you’re on the M6, and your other option is coasting to a roundabout. They price accordingly.
Supermarket forecourts are generally your best bet for low prices, which is why they appear so frequently on the comparison tools we’re about to look at. Asda in particular has historically been among the cheapest in the country, partly because it uses fuel pricing as a loss-leader to get people into the store. Morrisons, Tesco, and Sainsbury’s follow a similar logic.
There’s also regional variation. Fuel tends to be cheaper in urban areas with high competition and expensive in rural areas where the nearest alternative station might be twelve miles away. Scotland and some parts of Wales and Northern Ireland can be notably pricier. If you live somewhere remote, you’re partly at the mercy of your local geography.
Finally, there’s the VAT and duty component. Around 55-60% of what you pay at the pump goes straight to HMRC in the form of fuel duty and VAT. That’s relatively fixed, but it means the “profit margin” that stations compete on is actually quite a thin slice of the overall price which is why even small differences in pence-per-litre matter a lot to forecourt operators.
The Best Websites To Find Cheap Petrol Near You
1. Petrol Prices
Petrol Prices is probably the most well-known dedicated petrol price comparison site in the UK and has been around since the mid-2000s. That longevity isn’t an accident it does the job reasonably well.
The basic premise is simple: you type in your postcode or town, set a search radius, and it shows you a list of nearby stations sorted by price. You can filter by fuel type unleaded, diesel, super unleaded, premium diesel and it will show you the cheapest options at the top.
The site relies on a combination of data sources. Some prices come from user reports, some from direct data feeds from certain retailers, and some are estimated based on recent trends. This is worth keeping in mind, because user-reported prices can be a day or two out of date. I’ve turned up at a station expecting 143p per litre and found it was 146p because someone had submitted the price two days earlier before a mid-week adjustment.
That said, even slightly out-of-date data is still useful for identifying which stations in your area tend to be cheapest. The supermarkets especially tend to move their prices in a fairly predictable way if Asda was the cheapest yesterday, it’s probably still the cheapest today, just maybe by a different margin.
The free version of the site gives you basic search functionality. There’s a premium subscription option that gives you price alerts so you can set a threshold and get notified when local prices drop below a certain point and some additional features. Whether that’s worth paying for depends on how much you drive and how seriously you want to optimise your fuel spend.
The mobile app works well enough, though in my experience the website is actually easier to navigate on a phone browser than the app itself. Personal preference, but worth mentioning.
Best for: General comparison, finding the cheapest station in a given area, occasional drivers who want a quick reference.
2. Confused.com Petrol Prices Tool
Confused.com’s petrol prices section doesn’t have its own live price-tracking database the way Petrolprices.com does, but it publishes regular guides and data roundups that are genuinely useful for understanding broader trends. Their content team tracks average prices by region, highlights which supermarkets are cheapest nationwide, and publishes seasonal analysis.
If you want to understand why prices are moving in a particular direction whether it’s crude oil fluctuations, seasonal demand, or government duty changes their editorial content is solid. They also link out to the actual price-tracking tools when they discuss them, so it can be a useful starting point if you’re new to this whole area.
3. Zap-Map (for EV drivers who also drive a petrol car)
Zap-Map is primarily known as the go-to app for electric vehicle charging point locations in the UK, but it’s worth mentioning in this context for a particular type of driver: those who own both an EV and a petrol or hybrid car.
Some people in this situation use Zap-Map for their EV and one of the above tools for their petrol car, which makes sense. I include Zap-Map here partly to acknowledge that the future of fuel pricing tools might look quite different as the UK transitions toward electrification but also to note that it doesn’t currently serve as a petrol price tracker, so don’t go expecting that.
4. AA Fuel Price Monitor
The AA’s fuel price pages are less about finding the cheapest station near you and more about understanding the national picture. The AA publishes monthly (and sometimes more frequent) data on average UK petrol and diesel prices, broken down by fuel type and region.
This is proper research-grade data. The AA has been tracking fuel prices for decades and their data is widely cited by journalists and the government alike. If you want to understand whether prices in your area are above or below the national average, or whether diesel has become disproportionately expensive compared to petrol (it has), the AA’s fuel price monitor is where you go.
They also publish a useful breakdown of what makes up the price you pay at the pump showing the split between wholesale fuel cost, fuel duty, VAT, and retailer margin. Seeing that breakdown makes you realise how little the actual forecourt operator controls: a big chunk of what you’re paying is just tax, full stop.
The AA also runs campaigns around fuel pricing they were prominent voices lobbying the government when pump prices shot up dramatically in 2021 and 2022. If you want to understand the political and economic context of UK fuel prices, following their commentary is worthwhile.
Best for: Understanding national trends, researching regional price variation, background context on why prices move.
5. RAC Fuel Watch
Similar in spirit to the AA’s monitoring, RAC Fuel Watch publishes regular fuel price data and commentary. The RAC tends to be particularly vocal about cases where wholesale oil prices fall but pump prices don’t follow suit quickly a phenomenon sometimes called “rocket and feather pricing” (prices rocket up when oil costs rise, but feather down slowly when oil costs fall).
Their Fuel Watch page is updated regularly and gives you current average prices for petrol and diesel. What the RAC does particularly well is contextualising price movements explaining whether the current high (or low) prices are connected to Brent crude movements, sterling strength, refinery issues, or geopolitical events.
During particularly volatile periods, the RAC has been known to call out specific retailers for profiteering, which is the sort of accountability journalism-adjacent content that’s genuinely useful if you’re trying to make sense of the market.
Best for: Staying informed on price movements, understanding the fuel market, reading editorial commentary on price fairness.
6. Supermarket Fuel Price Pages
This might sound obvious but it’s underused: most of the major supermarkets that operate forecourts publish their own price information online, and some update it daily.
Asda’s petrol statations fuel page is worth checking if there’s an Asda near you, because they’re consistently among the cheapest in the country and their prices are easy to find on the site. Tesco, Sainsbury’s, and Morrisons have similar pages, though they’re not always prominently linked from the main site navigation you may need to search for “fuel prices” within their sites specifically.
The advantage of going straight to the source is that these prices are current and accurate. You’re not relying on a community submission that might be a day old; you’re seeing what the supermarket says its price is right now.
The disadvantage is that you have to check multiple sites separately if you want to compare across supermarkets, whereas a tool like Petrolprices.com does that aggregation for you.
7. Google Maps
I’d wager that a lot of people don’t realise Google Maps has petrol price information baked in. If you search for petrol stations near you, Google will often display current prices alongside the listing, sourced from a combination of direct data partnerships and user submissions.
The coverage isn’t complete not every station has a price listed, and rural areas tend to have patchy data but in most urban and suburban areas, it’s surprisingly comprehensive. The interface is also incredibly convenient because most people have Google Maps open on their phone anyway.
To use it, search “petrol stations near me” in Google Maps, and look for the price figure under each station name. You can also filter specifically for cheapest stations using the price display. The data is often tied to supermarket and major brand partners who share it directly with Google, which means supermarket prices in particular tend to be accurate.
For a quick, zero-friction check of what’s near you, Google Maps is hard to beat. It won’t give you the depth of data that a dedicated petrol tracking site provides, but for most casual use cases, it’s more than adequate.
Best for: Quick checks on the go, people who are already using Google Maps for navigation.
8. CMA Fuel Finder
In 2023, the Competition and Markets Authority published a landmark report on the UK fuel retail market, concluding that drivers were being overcharged by hundreds of millions of pounds annually due to insufficient price competition. One of the outcomes was a recommendation and eventually a government mandate for fuel retailers to share their prices in real-time via a publicly accessible data source.
The CMA’s work on fuel transparency has been feeding into a government initiative to create a national fuel price database. This is still developing, but the direction of travel is that price transparency in the UK petrol market is going to increase significantly. The government has signalled that an official “PumpWatch” scheme will require large retailers to report prices daily, making it much easier for comparison tools to provide accurate, real-time data.
As this develops, keep an eye on the CMA’s publications and the government’s GOV.UK pages for updates. The tools that currently exist will likely get significantly better as this data becomes mandatory.
9. Fuel Price Twitter/X Accounts and Local Facebook Groups
This is slightly outside the “website” category but it’s too useful to leave out. In many towns and cities, there are local Facebook groups where residents tip each other off about cheap fuel. Search for “[your town] community” or “[your area] deals and offers” on Facebook and you’ll often find people posting when a local station drops its price.
Similarly, a handful of accounts on X (formerly Twitter) focus on UK fuel price updates, though the landscape there has changed significantly since Elon Musk’s takeover and some useful accounts have migrated to other platforms.
These informal networks are genuinely useful for hyperlocal information the kind of “Morrisons in Stafford just dropped to 139p” tip that you won’t find in a national database until someone submits it.
How to Actually Use These Tools Effectively
Knowing the sites exist is one thing. Getting real value out of them is another. Here’s how I approach it, having spent a bit of time figuring out what actually saves money versus what just feels like it should save money.
Don’t drive out of your way for cheap petrol. This sounds obvious but it’s worth stating explicitly. If a station is 5p cheaper per litre but it’s four miles in the opposite direction, you’re burning fuel to save fuel. Run the numbers: on a 50-litre fill, 5p per litre saves you £2.50. Four miles in the wrong direction (eight miles round trip) in an average car burns roughly 600ml of fuel at current prices, which costs you around 90p. Net saving: about £1.60. That’s fine, but it’s not the huge win it might initially appear.
The real gains come when a cheap station happens to be on your regular route. A station you pass every day on the way to work that’s consistently 7-8p per litre cheaper than the one you’ve been using out of habit? That adds up very quickly. Petrolprices.com and WhatGas are particularly good for this use case searching along a specific route rather than just around your current location.
Check prices before long journeys. If you’re doing a motorway trip, fill up before you get on. Motorway service fuel is routinely 15-20p per litre more expensive than off-motorway alternatives. If your car is running low when you set off, find the cheapest local station first, fill up fully, and then get on the road. The extra ten minutes is usually worth it.
Understand when prices typically move. Petrol prices in the UK tend to be adjusted mid-week, often on Tuesday or Wednesday, when wholesale price changes filter through to retailers. If prices have been falling (because oil is cheaper), Tuesday or Wednesday might be a good day to fill up before the week’s price is locked in. This isn’t a hard rule retailer behaviour varies but it’s a pattern worth being aware of.
Use supermarket loyalty points. Most supermarket forecourts let you collect Nectar (Sainsbury’s), Clubcard (Tesco), or Morrisons More points when you fill up. These aren’t huge amounts, but they add up over time. If two stations near you are priced identically, filling up at the one where you collect loyalty points is an obvious win.
Set price alerts where available. Petrolprices.com’s premium service lets you set alerts when prices in your area drop below a threshold. If you’re not in a rush and your tank isn’t running low, this can be a useful way to time fills for cheaper days.
The Supermarket Price War and What It Means for You
One of the most significant developments in UK petrol pricing over the past decade has been the dominance of supermarket forecourts. Asda, Tesco, Sainsbury’s, and Morrisons between them account for a substantial proportion of UK fuel sales, and they’ve maintained prices below the national average consistently.
This has happened for a straightforward commercial reason: cheap petrol gets people into the car park, and once they’re in the car park, they’re likely to pop into the shop. The margin on a tank of fuel is thin; the margin on a trolley of groceries is considerably better. Cheap fuel is, in this sense, a sophisticated form of marketing.
The result for consumers is that if you live within reach of a supermarket forecourt, you have a structural advantage over people who don’t. The difference between supermarket and branded forecourt prices has been measured at anywhere from 5p to 15p per litre over the past couple of years sometimes more during price spikes.
For a driver doing average UK mileage (around 7,000-8,000 miles a year in a car doing 40 miles per gallon), that could mean a saving of £100-£150 annually just by consistently choosing supermarket fuel over branded alternatives. That’s not transformative money, but it’s a nice meal out or a chunk off a utility bill.
A Word on Premium Fuel Is It Worth Paying More?
Most of the petrol price comparison tools cover multiple fuel types, and you’ll notice that “super unleaded” and “premium diesel” sold under names like V-Power (Shell), Ultimate (BP), and Synergy Supreme (Esso) are consistently more expensive, often by 10-20p per litre.
The question of whether premium fuel is worth paying for is genuinely complicated and I won’t pretend otherwise. The short version is: for most cars on most journeys, standard unleaded or diesel is perfectly fine and you won’t notice a meaningful difference. Modern car engines are designed to run on standard fuel.
The longer version is that premium fuels contain higher proportions of cleaning additives and, in the case of super unleaded, have a higher octane rating. For high-performance engines particularly turbocharged engines in sportier cars the higher octane can theoretically allow the engine management system to extract more power and efficiency, possibly offsetting some of the higher cost. But in a family hatch or SUV, the difference in real-world performance and economy is usually negligible.
If your car manufacturer specifies super unleaded (check your handbook or the inside of the fuel filler cap), use it. If they don’t, standard unleaded is almost certainly all you need, and the money saved by using the comparison tools to find cheap standard fuel is better in your pocket than spent on premium.
Electric Vehicles and the Changing Future of Fuel Price Tracking
I’d be remiss not to acknowledge that the whole landscape of “where do I find cheap fuel” is shifting under everyone’s feet. The UK’s ban on new petrol and diesel car sales (currently pushed back to 2035) means that EVs are going to make up an increasing share of the vehicle fleet over the coming years.
For EV drivers, the equivalent question is “where do I find cheap electricity to charge?” and that’s a significantly more complex question. Home charging rates vary by energy tariff, public rapid charger prices have risen sharply in 2023 and 2024, and the disparity between home charging costs and public charging costs can be enormous. Zap-Map (mentioned earlier) and Charging Near Me help locate chargers, but price comparison across public charging networks is still less mature than petrol price comparison.
For the many millions of people who will be driving petrol and diesel cars for the next decade or more, though, the tools we’ve looked at remain very relevant. The market isn’t going to flip overnight, and even when new EV sales outpace ICE vehicles, the secondhand market will keep petrol cars on UK roads well into the 2040s.
Regional Price Variation: Where Are Prices Highest and Lowest?
If you’re curious about the geography of UK fuel prices, the patterns are fairly consistent over time, though they shift with market conditions.
Cheapest regions tend to be the Midlands and parts of Yorkshire and Lancashire, where there’s high population density, strong supermarket competition, and a lot of volume-based discounting. Areas around cities like Birmingham, Leeds, Sheffield, and Manchester often see prices cluster at the lower end of the national range.
Most expensive regions are typically remote rural areas parts of Scotland, Wales, Cornwall, and Northern Ireland. The island of Islay, for example, can have fuel prices 20-25p per litre above the mainland average. There’s simply less competition, higher transport costs to get the fuel there, and limited alternatives for local residents.
London is interesting: you’d expect it to be expensive given its general cost of living, and some stations particularly in the City or West End are indeed pricey. But the density of supermarket forecourts in outer London and the South East means that if you’re willing to drive a few minutes off your immediate route, you can usually find competitive prices.
The AA’s regional price data (linked above) gives you the most rigorous breakdown of these differences, if you want to put precise numbers on it.
The Environmental Angle: Does Driving for Cheap Fuel Make Sense?
I want to briefly acknowledge an elephant in the room. A lot of this guide is about saving money on fuel by driving to cheaper stations, but there’s an environmental dimension to that choice that’s worth at least naming.
Burning petrol and diesel produces CO2 emissions. If you drive eight miles out of your way to save £3 on a fill-up, you’ve emitted roughly a kilogram of CO2 in the process of saving that money. Whether that trade-off makes sense depends on your values, and I’m not going to moralize about it. But it’s a reason why I’d emphasise the “on your regular route” strategy over the “drive to the cheapest station in the county” approach.
The comparison tools themselves don’t have an environmental footprint using Petrolprices.com to find the cheapest station on your normal commute route is a pure win: you save money without driving any extra distance. That’s the sweet spot these tools are best used for.
Fuel Price Alerts Setting Yourself Up for Smarter Filling
If you want to be more systematic about this rather than just checking sites ad hoc, here’s a routine that works:
Check Petrolprices.com or WhatGas once a week, on a Monday morning, to see what prices look like near you. If prices are in a downward trend (the AA’s commentary will tell you if oil prices have been falling), you might wait a few days before filling up. If prices are rising or volatile, fill up when you’re around a quarter tank rather than waiting until the warning light comes on.
Set up a price alert on Petrolprices.com if you use the premium version, with a threshold that represents “genuinely good value” for your area. When that alert fires, fill up fully rather than just topping up that way you make the most of the low price window.
Follow WhatGas for local community tips, particularly if you live in an area with a few competing stations. Local knowledge about which station is consistently cheapest or tends to undercut others can save you a lot of comparison-shopping time.
Frequently Asked Questions
Which is the cheapest petrol station chain in the UK?
Asda has historically topped most surveys for cheapest average pump prices, followed by Morrisons and Tesco. That said, it varies by region and by week the comparison tools above will give you a current picture for your area.
How often do petrol prices change?
Major supermarket chains tend to update prices once or twice a week. Smaller independents may change prices daily or even more frequently in response to local competition. Motorway services tend to change less often and are almost always more expensive regardless.
Is diesel or petrol cheaper right now?
This changes over time. As of late 2024, diesel has generally been more expensive than petrol in the UK, often by 5-10p per litre. This is a reversal of the situation from several years ago and has made diesel vehicles more expensive to run than many owners expected. Check the AA or RAC links above for current average prices.
Can I use these websites outside the UK?
The websites listed here are UK-specific. For Ireland, a similar service called Pumps.ie exists, though that’s the Republic of Ireland rather than Northern Ireland. Northern Ireland uses the UK tools but has its own pricing dynamics.
Why does petrol cost more at motorway services?
Partly because of captive demand (you’re there, you need fuel, your alternatives are limited) and partly because motorway service operators pay premium rents and have higher operating costs. The Competition and Markets Authority has noted this as an ongoing concern.
Finding cheap petrol in the UK doesn’t require a huge amount of effort, but it does reward a bit of attention. The tools are there Petrolprices.com, WhatGas, Google Maps, the AA’s fuel monitor, the RAC’s Fuel Watch and together they give you a pretty complete picture of what’s available near you.
The biggest single insight from years of paying attention to this stuff is: consistency beats one-off hunting. Knowing that your local Asda is reliably 8p cheaper than the BP on the high street, and then actually filling up at Asda every single time, will save you more money than obsessively checking prices every day and occasionally landing a bargain elsewhere.
Build the habit, use the tools to inform it, and keep an eye on the bigger picture via the AA and RAC for context when prices are moving sharply. It won’t make you rich, but over the course of a year, being smart about where you fill up is worth real money the kind that accumulates quietly but consistently, like all the best savings do.
