The easiest way to calculate the cost of your driving based on your car reg plate

In today's volatile economy, fluctuating fuel prices are a common worry among UK drivers. Whether planning a weekend getaway or a quick trip to the supermarket, considering fuel costs is essential. While various online tools offer fuel cost calculations, they often fall short by requiring manual input of fuel prices, which may not be up to date. That's where Roadtrip steps in - your go-to app for precise fuel cost estimates tailored to your vehicle and journey.

How Does Roadtrip Work?

Roadtrip simplifies the fuel cost calculation process by requiring just three key pieces of information: your starting point, destination, and vehicle registration number (reg).
