Is Charging an EV Cheaper Than Fueling a Petrol or Diesel Car?
Everything Hertfordshire Homeowners Need to Know About EV Charger Installation
Yes — charging an electric vehicle (EV) is usually much cheaper than fuelling a petrol or diesel car, especially when you have your own home EV charger installation. With rising fuel prices and the UK’s push towards greener energy, now more than ever, making the switch to electric can save you money in the long run. If you’re in Hertfordshire and thinking about switching to an EV or installing a home charger, this guide breaks down all the key points — from cost comparisons to long-term savings and government grants.
💡 What Does It Cost to Charge an EV at Home?
With a home EV charger installation, you’re looking at paying around 30p per kWh (based on average UK tariffs), which means a full charge for a typical 60kWh EV battery costs about £18 — giving you a range of up to 250 miles. Compare that to £1.50+ per litre of petrol, and you’re immediately saving money every time you plug in.
Cost per 100 miles
EV with home charger: ~£6.75
Petrol car: ~£15–£20
Installing a home EV charger in Hertfordshire gives you full control over when and how you charge. With smart chargers and off-peak tariffs, you could pay even less.

💷 EV Charging vs Fuel Costs Over a Year
Let’s break down the numbers based on 8,000 miles annually:
| Type | Average Cost per Year |
|---|---|
| EV (Home Charging) | ~£270 |
| Petrol Car | ~£1,200 |
| Diesel Car | ~£1,050 |
Not only is charging at home cheaper, but there’s less engine wear, fewer repairs, and no oil changes — reducing your overall maintenance costs by up to 50%.
🧠 Smart Charging: How to Save Even More
Installing a smart EV charger lets you schedule charges during off-peak hours — usually overnight — when electricity is cheaper. Some suppliers offer special EV tariffs like:
Octopus Go
British Gas EV Tariff
EDF’s GoElectric
Using smart features, you can reduce your cost per kWh to under 10p — potentially bringing your annual charging cost below £150.
🏡 Benefits of Installing a Home EV Charger in Hertfordshire
Cost Savings: Home charging is cheaper than public chargers or fuel stations.
Convenience: Charge overnight and start each day with a full battery.
Increased Home Value: EV-ready homes are more attractive to buyers.
Government Support: The EV chargepoint grant offers up to £350 off installation costs.
🔍 Is Public Charging More Expensive?
Yes — public charging often comes with higher costs and additional connection fees. Rapid chargers (DC fast charge) can charge per kWh and also include standing fees, costing you up to £40 per full charge. That’s more than double the cost of charging at home with your own EV charger.
