Every UK forecourt, every price.

How Does Live UK Fuel Price Data Actually Work?

Since the Motor Fuel Price (Open Data) Regulations 2025 came into force, every filling station operating in the UK is legally required to report any price change within 30 minutes of it happening. The data flows through the government's Fuel Finder API and is made publicly available — including to tools like this one.

We pre-cache the entire UK dataset every 5 minutes on our own server, so the map above loads in 2–3 seconds rather than the 10–30 seconds it would take querying the government API directly. The prices you see are never more than 35 minutes old — in practice, far fresher than any printed price board you drive past.

Unlike Google Maps or Waze, which aggregate price reports from users (meaning data can be days stale), every price on this map is a legally mandated, machine-reported figure. Forecourts that fail to report accurately face regulatory action. You can trust what you see.

Why Was the Fuel Finder Scheme Introduced?

The Competition and Markets Authority (CMA) found in its 2023 investigation that UK drivers were paying an estimated £900 million per year more than necessary due to a lack of price transparency. Mandatory open-data reporting was the government's response. For drivers, the result is simple: real-time prices, legally enforced, available to every app and website for free.

The scheme has measurably reduced the "rockets and feathers" effect — the pattern where pump prices rise quickly when wholesale costs increase but fall slowly when they decrease. With every price change now legally reported within 30 minutes, regulators, journalists, and tools like this can catch stations that are slow to pass on wholesale savings.

Which Fuel Does Your Vehicle Need? A Plain-English Guide

Our map covers all six fuel types tracked under the Fuel Finder scheme. Here's what each one means — and how to choose when you're at the pump.

Where Can I Find HVO Fuel Near Me?

HVO (Hydrotreated Vegetable Oil) is the fastest-growing fuel category in 2026. It's chemically similar enough to fossil diesel that most modern diesel vehicles can use it without modification, but you should always check your vehicle handbook or manufacturer's website first. Select "HVO" from the fuel toggle on the map above to filter to stations currently reporting HVO prices in your area.

HVO availability is currently concentrated at commercial and specialist forecourts rather than supermarket sites. If you're running a van fleet or want to reduce your carbon footprint, HVO is worth monitoring — its price relative to standard diesel can fluctuate significantly with wholesale market conditions, and the gap has been narrowing as supply scales up through 2025–2026.

Is Premium Diesel Worth the Extra Cost?

For most drivers doing ordinary mileage in a modern diesel car, the honest answer is: probably not. The cleaning additives in products like Shell V-Power Diesel or BP Ultimate Diesel benefit engines that have accumulated carbon deposits — typically vehicles with 50,000+ miles, or those used mainly on short urban trips. Use the "Premium Diesel" toggle on the map to compare the premium diesel vs standard diesel price gap at stations near you and decide whether it's worth it today.

What Is the Difference Between E10 and E5 Petrol?

E10 (standard unleaded) has been the default pump grade at UK forecourts since September 2021 and is suitable for the vast majority of petrol cars built after 2011. E5 (premium unleaded, "Super Unleaded") contains no more than 5% ethanol and is the protected grade for older and classic vehicles not approved for E10 use. E5 typically costs 10–20p/litre more than E10. If your car requires E5, use the "Premium Unleaded" filter on the map to find stations stocking it nearest to you.

How to Find the Cheapest Petrol or Diesel Near You

The map above is your fastest route to the cheapest fill-up. Here's how to get the most from it:

1. Allow location access — click "My Location" to centre the map on where you are now, or type a postcode or town name into the search box.
2. Select your fuel type — use the toggle to switch between Unleaded, Diesel, Premium Unleaded, Premium Diesel, B10, or HVO.
3. Switch to "Sort: Cheapest" — the results table reorders so the cheapest nearby station is at the top.
4. Check the 50-litre cost column — this converts the price-per-litre into a real-world tank fill cost, making the actual saving tangible.

The price circles on the map are colour-coded: green = cheapest in the current view, amber = mid-range, red = most expensive. This makes it easy to spot bargains at a glance before you even look at the table.

Are Supermarket Petrol Prices Really the Cheapest?

Almost always, yes. Tesco, Asda, Morrisons, and Sainsbury's have historically been the cheapest fuel retailers in the UK — typically 3–8p/litre below branded forecourts like BP, Shell, or Esso. On a 50-litre fill, choosing a supermarket over a motorway service station can save you £3–£5 per tank — roughly £150–£250 per year for an average driver. The one area where branded stations win is HVO and premium fuels: supermarkets don't stock them. Use the fuel type filter above to find the best price among stations that carry what your vehicle needs.

How Much Can Fuel Prices Vary Within a Few Miles?

Significantly. In busy urban areas, there's often a spread of 5–15p/litre between the cheapest and most expensive stations within a 3-mile radius. A 10p/litre saving on a 55-litre tank puts an extra £5.50 back in your pocket — for a commuter filling up once a week, that's over £280 a year. Zoom into your local area and switch to "Sort: Cheapest" to see exactly what that spread looks like right now where you live.

UK Fuel Prices in 2026: What's Driving the Market?

UK pump prices are shaped by four main forces: the wholesale price of crude oil (set by global markets), the cost of refined fuel (refinery margins and logistics), UK Fuel Duty (currently 52.95p/litre — legislated increases are scheduled for September 2026, December 2026, and March 2027 as the 2022 emergency cut is unwound), and VAT at 20% added to the total.

Fuel Duty and VAT together account for roughly 45–50% of the price you pay at the pump for standard unleaded. When wholesale prices spike, the fixed tax component means the impact on drivers is proportionally larger — and when wholesale prices fall, you never get the full benefit back.

The 2025 open-data regulations have brought greater transparency to how quickly stations pass on wholesale savings. With every price change now legally reported within 30 minutes, the "rockets and feathers" effect — where prices rise fast but fall slowly — is far easier to document and challenge than it was before the scheme launched.

What Is the Average Petrol Price in the UK Right Now?

National average prices shift daily. The most accurate answer is always on our live map — use "Sort: Cheapest" with your fuel type selected to see the current range in your search area. For context, UK average unleaded petrol ranged between 145p and 165p/litre through Q1 2026, with diesel running approximately 5–10p/litre higher in most regions.

HVO vs Diesel: Is the Price Gap Getting Smaller?

As HVO production has scaled up through 2024–2026, the price premium over standard B7 diesel has narrowed from around 20–30p/litre to closer to 10–18p/litre at retail pumps. For fleet operators and commercial van drivers, the total cost of carbon offset — combined with increasing ULEZ and Clean Air Zone compliance requirements — is making HVO increasingly competitive on a total cost basis. Use the HVO filter on the map to find the current HVO vs diesel price gap at stations near you today.

UK Fuel Duty 2026: What You're Actually Paying in Tax

Every litre of petrol or diesel you buy in the UK carries a substantial fixed tax burden long before VAT is even applied. Understanding how pump prices are constructed helps explain why prices sometimes feel sticky even when oil markets fall — and why several price increases are now legally scheduled between now and March 2027.

The current standard rate of UK Fuel Duty is 52.95p per litre, applied equally to petrol and diesel. On top of that, VAT at 20% is charged on the total pump price (including the duty itself, which means you pay tax on tax). Together, duty and VAT account for roughly 45–50% of what you pay at the pump for standard unleaded. The remainder covers wholesale product cost, refinery margins, logistics, and the retailer's margin — which, for supermarkets in particular, is often razor-thin.

Upcoming UK Fuel Duty Increases — What to Expect

The 5p/litre emergency fuel duty cut introduced in March 2022 in response to the energy crisis is now being legislatively unwound in a series of scheduled increases. These are not speculative — they are published government policy:

By March 2027, the cumulative effect will be a 5p/litre increase on the pre-2022 rate, adding approximately £2.75 to a 55-litre fill compared to today. For a driver filling up weekly, this represents around £143 per year in additional fuel duty alone — before VAT is applied.

What Is the Rockets and Feathers Effect?

The "rockets and feathers" effect describes the well-documented pattern where UK pump prices rise rapidly when wholesale oil costs increase (the rocket), but fall far more slowly when wholesale costs drop (the feather). The Competition and Markets Authority estimated this asymmetry cost UK drivers approximately £900 million per year in excess charges prior to the 2025 open-data regulations. With every price change now legally reported within 30 minutes, tools like this map can track exactly how quickly — or slowly — stations pass on wholesale savings. If you notice the map showing high prices that haven't moved despite falling oil news, that data is now a matter of public record.

Motorway Fuel Prices: How to Avoid the Junction Tax

If you've ever filled up at a motorway service station and winced at the price, you're not imagining it. Motorway forecourts routinely charge 20–25p per litre more than independent or supermarket stations located just off the same junction. On a 55-litre fill, that's a difference of £11–£14 for exactly the same fuel. The premium exists because captive motorists on long journeys are less likely to detour, giving service operators significant pricing power. This is one of the starkest price disparities in UK retail, and it's now fully visible in the live data.

How to Find Cheap Petrol Near Motorway Junctions

You don't need location-specific pages to find the best price near a motorway junction — the live map above does it in seconds. Here's the approach: before you leave (or at a safe stop), open the map, search for the junction number or nearby town, zoom in to roughly a 2–3 mile radius, and switch to "Sort: Cheapest." In most cases you'll find a supermarket forecourt — Tesco, Asda, Morrisons, or Sainsbury's — within two miles of the junction charging 15–25p/litre less than the service station on the motorway itself. On routes like the M6, M1, M4, M25, M5, and A1, this search consistently surfaces savings of £10 or more per tank.

The live API data updates within 30 minutes of any price change, so you're seeing the current price at that specific forecourt — not a crowdsourced estimate that might be days old. That's the core advantage over legacy apps: the data is legally mandated and machine-reported, not volunteered by other drivers.

Are Motorway Service Station Fuel Prices Regulated?

Currently, no. While all petrol stations — including motorway service operators — must report prices to the government Fuel Finder API within 30 minutes of any change, there is no price cap or ceiling applied to service stations specifically. The CMA has noted the premium as a concern and the increased transparency created by the 2025 open-data regulations was partly intended to exert market pressure on high-charging operators. Whether that transparency translates into genuine price competition at motorway locations remains to be seen — but at least you can now see exactly what they're charging before you commit to a stop.
