About Fuel Finder NI
Fuel Finder NI is a free, independent tool that shows live petrol and diesel prices at every registered forecourt in Northern Ireland — updated every 15 minutes directly from official government data.
With over 450 stations mapped across all six counties, you can see at a glance where the cheapest fuel near you is, compare prices across brands and locations, and filter by fuel grade. No account needed, no app to download.
How to use the map
- Choose a fuel grade using the tabs on the left (desktop) or the grade selector at the top (mobile). Diesel is selected by default.
- Browse the map — markers are colour-coded green (cheapest), amber (mid-range) and red (priciest) relative to other stations currently in view.
- Tap or click any marker to see full details: all fuel prices at that station, opening hours, and available facilities.
- Use the sidebar list (tap the Stations button on mobile) to see stations ranked cheapest-first. Tap "All NI" to compare across the whole region rather than just your current map view.
- Tap the lowest or highest price in the stats bar to jump straight to that station on the map.
- Use My Location to pan the map to where you are and see nearby stations in the list.
Fuel grades explained
Northern Ireland forecourts report up to six fuel grades through the GOV.UK Fuel Finder. Here is what each one means:
Standard UK petrol, containing up to 10% renewable ethanol. Compatible with most petrol cars made after 2011. Became the default UK grade in September 2021.
Premium petrol with a higher octane rating and no more than 5% ethanol. Required for some older and classic vehicles. Typically 5–10p per litre more expensive than E10.
Standard diesel containing up to 7% biodiesel. Compatible with all diesel vehicles and the most widely available diesel grade in Northern Ireland.
Standard diesel with added detergents to clean fuel injectors and improve efficiency. Sold as BP Ultimate Diesel, Shell V-Power Diesel, and similar branded grades.
Diesel with up to 10% biodiesel content. Approved for use in most diesel vehicles manufactured after 2016. Slightly lower carbon footprint than standard B7.
Hydrotreated Vegetable Oil — a drop-in replacement for fossil diesel made from waste vegetable oils. Up to 90% lower lifecycle CO₂ emissions. Currently available at a small number of NI forecourts.
About the data
Prices are sourced from the GOV.UK Fuel Finder API, which collects reported prices directly from UK fuel retailers. Forecourts are legally required to update their prices within 30 minutes of any change.
Fuel Finder NI fetches fresh data every 15 minutes and caches it server-side, so the prices you see are typically no more than 15–30 minutes old. The timestamp at the bottom of the sidebar shows exactly when the data was last fetched. Individual station prices also show when that specific price was last updated.
Only Northern Ireland stations are shown — identified by BT postcodes and country designation in the API. Permanently or temporarily closed stations are automatically excluded.
Frequently asked questions
Why does the same station sometimes show different prices on different days?
Fuel prices change frequently — often daily — based on wholesale costs, competition, and local market conditions. Some stations update prices multiple times a day. The price you see always reflects the latest reported price from that forecourt.
Why are some stations missing a fuel grade?
Not all stations sell every grade. Niche grades like HVO and B10 are currently available at only a handful of forecourts in Northern Ireland. If a station doesn't stock the selected grade, it won't appear on the map for that filter.
Are supermarket fuel prices included?
Yes — supermarket stations such as Tesco, Asda, Morrisons and Sainsbury's are required to participate in the GOV.UK Fuel Finder scheme and their prices are included in the data.
Does Fuel Finder NI work on mobile?
Yes. The site is fully responsive and optimised for use on smartphones. On mobile, the map fills the screen and a bottom sheet slides up to show the station list. Tap the Stations button or any map marker to explore prices.
Who runs Fuel Finder NI?
Fuel Finder NI is an independent website. It is not affiliated with the UK government, the Fuel Finder scheme, or any fuel retailer. It uses the GOV.UK Fuel Finder open data API to present public price data in a convenient format for Northern Ireland drivers.
