You pull up to the pump, fill your tank, and then drive half a mile down the road only to see petrol for 5p less a litre. Annoying, right? We’ve all been there.
In 2026, rising bills stretch household budgets, and filling the car remains a massive regular expense. With pump prices constantly shifting, drivers need to be savvier than ever about where they refuel. Luckily, your phone is the ultimate tool for combating high forecourt prices and stretching your travel budget further.
We’ll show you exactly how to use the top iOS and Android apps to compare local petrol and diesel prices in real-time, helping you save money on every single tank. Let’s dive in…
Download the PetrolPrices app.
Let's start with the big one. PetrolPrices is the most comprehensive, dedicated fuel comparison app available in the UK.
It uses a clever mix of corporate data and updates from everyday drivers to give you highly accurate petrol, diesel, and premium fuel costs. Our favourite feature lets you set a specific search radius (like five miles) around your postcode to find the absolute cheapest local forecourt.
You can grab it right now from the App Store or the Google Play Store.
Use the maps you already have.
You might not even need a new app. The standard navigation apps you probably already use, like Google Maps, Waze, and Apple Maps, are fantastic tools for finding the cheapest fuel on the go.
When you hit the road, simply search "petrol stations" within the app. You'll instantly see prices pop up right on the map interface along your planned route.
Don’t forget to take advantage of the brilliant eco-friendly routing features built into these apps, too. They calculate the most fuel-efficient journey for you, helping you save money regardless of what the pump price says.
Bag a bargain at the supermarket.
It’s no secret that the cheapest fuel often sits at supermarket forecourts. That makes apps like Tesco Grocery & Clubcard or Asda Rewards essential companions for your drives.
We recommend using a comparison app to find the cheapest supermarket first, then simply scan your digital loyalty app when you fill up to earn points or unlock exclusive pump discounts.
It’s super convenient – you can even add these loyalty cards directly to Apple Wallet or Google Wallet for lightning-fast, contactless payments.
Don't forget about Costco.
If you have a Costco nearby, it’s well worth checking if you qualify for a membership. Their petrol and diesel are often several pence cheaper a litre than standard forecourts. You can grab an individual membership if you work in certain sectors, like education, healthcare, emergency services, or local government. If you're eligible, it's a fantastic way to slash your fuel bill.
Stretch your tank even further.
While finding cheap fuel helps, driving efficiently saves you even more money. Here are a few quick tips to get the most out of every single drop:
- Check your tyres: Ensure your tyre pressure is correct to reduce drag and keep your car rolling smoothly.
- Ditch the roof box: Remove heavy roof boxes when you aren't using them to improve your aerodynamics.
- Drive smoothly: Avoid harsh braking and rapid acceleration to keep your fuel consumption low.
Ready to hit the road?
Let's recap. Tracking fuel prices through your phone is a necessity to keep motoring costs down. PetrolPrices offers the most dedicated local forecourt comparison, while standard map apps allow you to find cheap fuel on your route and utilise eco-friendly navigation. Combining these tools with digital supermarket loyalty apps and a Costco membership maximises your savings.
