Is an Electric Car Cheaper Than Petrol? A Real Cost Comparison
With fuel prices rising and more drivers considering switching to electric, it’s no surprise that people are asking: Is an electric car cheaper than petrol? The answer isn’t always black and white, but when you break down the real costs, some clear differences start to appear.
In this guide, we’ll compare electric cars vs petrol cars, looking at running costs, purchase prices, charging and fuel costs, and what day-to-day ownership really looks like in the UK. If you’re deciding between an electric or petrol car, this breakdown will help you understand where the savings can come from.
Electric Cars vs Petrol Cars: What Are You Really Paying For?
When comparing electric cars and petrol cars, it helps to split costs into two main areas:
-Upfront purchase prices.
-Ongoing running costs.
While electric vehicles (EVs) often cost more to buy initially, their lower running and maintenance costs can make a big difference over time, especially if you cover a lot of mileage.
Purchase Prices: Electric or Petrol Car?
It’s true that, on average, electric cars still have higher purchase prices than petrol and diesel cars. Battery technology is improving, but EVs can cost more upfront, especially newer models.
However, the gap is closing. The used EV market is growing, and more affordable models are becoming available. For many drivers, finance plays a big role too and spreading the cost can make switching to electric more manageable.
Curious about what your options might look like?
Running Costs: Electric Car vs Petrol in the UK
This is where things really start to shift. When looking at the cost of running an electric car vs petrol in the UK, EVs usually come out cheaper day to day.
Fuel Costs vs Charging Costs
Petrol and diesel prices fluctuate constantly, making fuel costs unpredictable. Electric cars, on the other hand, are charged using electricity, which can be cheaper. Here’s what you need to know:
-Charging at home using a standard rate is often cheaper than filling up with petrol.
-Dedicated EV tariffs can reduce charging costs further.
-Public charging points cost more, but are still often competitive compared to fuel prices.
Cost Per Mile: Electric Car vs Petrol
One of the clearest comparisons is the cost per mile electric car vs a petrol car. While exact figures depend on fuel price, electricity rates, and vehicle efficiency, electric cars typically cost less per mile to run.
On average:
-Electric cars often cost significantly less per mile than petrol or diesel cars.
-Petrol cars are more affected by rising fuel costs.
-EVs benefit from consistent electricity pricing and efficiency.
This makes the cost per mile a major reason why many drivers are switching to electric cars.
Maintenance Costs: Fewer Moving Parts, Fewer Problems
Another big difference in the EV vs petro debate is maintenance. Electric vehicles have far fewer moving parts than petrol or diesel cars. There’s no exhaust system, no oil changes, and no clutch.
This often leads to:
-Lower maintenance costs.
-Fewer unexpected repair bills.
-Less time spent in garages.
Clear Air Zones and City Driving
If you regularly drive in cities, clear air zones can have a big impact on running costs. Petrol and diesel cars may face daily charges in certain areas, while electric cars are usually exempt.
For urban drivers, this can tip the balance further in favour of electric, especially if you commute through regulated zones.
Electric Cars vs Petrol Cars for Different Driving Habits
There’s no one-size-fits-all answer when choosing an electric or petrol car. However, your driving habits can usually give you a good indication of which type is better suited to you.
Electric cars may suit you if:
-You drive predictable daily miles.
-You can charge at home or work.
-You want lower running and maintenance costs.
Petrol or diesel cars may suit you if:
-You do very long journeys regularly.
-Rely heavily on motorway driving.
-Don’t have access to a home charger.
EV vs Petrol: Charging Convenience
Charging is one of the biggest mindset shifts when switching to electric. Home charging is often the cheapest and most convenient option, but public charging points are essential for longer trips.
While charging does take longer than filling a petrol or diesel car, many drivers charge overnight at home and rarely need to visit a public charging point.
Is Switching to an Electric Car Worth It?
Switching to electric isn’t just about cost, although cost is always a big part of the decision. For many drivers, lower running costs, reduced maintenance, and protection from rising fuel prices make EVs an attractive option.
If you’re still weighing up electric cars vs petrol cars, it’s worth thinking about:
-How far you usually drive your car.
-Where you’ll charge your car.
-Your typical fuel spend.
-Your budget and finance options.
