Why should I compare fuel prices in London?

With London’s high cost of living, every bit of savings helps. Fuel prices can vary significantly, even within a short distance, and using our fuel price checker can make a real difference in your budget. London drivers also face additional expenses like the Ultra Low Emission Zone (ULEZ) and congestion charges, making it even more valuable to save on fuel costs.

By comparing prices, you can avoid paying more than necessary and save money at the pump. If you’ve ever refuelled only to see a cheaper station just down the road, you know how frustrating that is – our tool helps you avoid that situation. Even small price differences add up, so checking fuel prices can be a smart way to stretch your budget further in the city.

How to save money on fuel in London

1. Compares prices

The easiest way to save money on fuel is to compare prices before you head out. Our useful fuel price checker will show you where to find the cheapest fuel in your area. You can also plan ahead on longer trips to see which locations along your route might give you the best savings.

2. Drive more efficiently

You can also save money by thinking about the way you drive. Generally speaking, the smoother you drive, the more economical you’ll be. Accelerating is what uses the most fuel, so coasting towards a traffic light so it goes green before you have to stop will use less fuel than pulling away from stationary (though, obviously, don’t go too slowly with other cars around you). Reducing your speed also helps, so you could consider driving at 60mph on the motorway instead of 70mph.

3. Maintain your vehicle

A properly maintained car will be more efficient than one that’s been neglected. You might think you’re saving cash by not getting your car serviced or repaired, but worn and damaged parts require more energy to move than a new, well-oiled piece.

4. Clear out your car

The heavier something is, the more energy is required to carry it. So if you have a boot full of stuff that you never need on a journey, give it a good clear out. Reducing weight will help you use less fuel and save cash at the pumps.

Similarly, remove any roof racks or roof boxes that you’re not using. These create extra drag, which in turn requires more fuel to maintain a given speed.

5. Turn off the air conditioning

Anything that uses the engine to run will use fuel, and one of the most common culprits is the air conditioning. In newer cars the difference might be minimal, but in older cars it can make a marked improvement. If it’s not boiling hot outside and you don’t need the extra chill, turn off your air-con and improve your fuel economy.

Petrol and diesel prices in London FAQs

Why is diesel more expensive than petrol?

There are a couple of key reasons. The first is that diesel is heavier than petrol, and therefore costs more to import and distribute. The diesel used in cars is pretty much the same as that used for heating in some countries, meaning there’s more competition, too.

Is premium fuel worth it?

The answer largely depends on what sort of car you drive. For most family cars, the higher fuel rating won’t make much difference. You might find the engine runs a bit more efficiently or lasts a bit longer, but it probably won’t offset the extra cost at the pump.

It’s a different story for performance cars, which would benefit from premium fuel – you might notice better throttle response. Because the engine is working harder, premium fuel should have reliability benefits, too.

If you own a diesel car, premium fuels are typically designed to help clear out any gunk in your system, so it can benefit from putting the occasional tank of premium diesel in from time to time.

How is fuel taxed?

Fuel is taxed in two ways. The first is a fuel duty, which is set at 52.95p per litre, and the second is 20% VAT, which is charged on the final transaction cost.

Why do fuel prices vary by location?

There are lots of reasons why fuel costs vary by location, but much of it is down to competition. In areas where there are lots of supermarkets, this can drive costs down, while rural areas tend to be pricier because you have fewer alternative options. Affluent areas, such as big cities, will often have higher prices than elsewhere, too.

Is an electric car cheaper to run than petrol or diesel?

This depends entirely on how you charge it. Even though the cost of electricity has increased in recent years, if you can charge at home, most people will find an electric car cheaper than petrol or diesel.

Some workplaces have chargers on-site that are free or subsidised, so this is another option, while some councils have installed chargers at the roadside in residential areas – although you will have to pay to use the majority of these.

However, if you’re relying solely on public charging, it’s probably best to stick to petrol or diesel for now. That’s because public EV charging is generally pretty expensive, and unless you can find a charger located in a way that suits your lifestyle, it can be annoying having to spend your free time charging a car away from home.
