What electric cars are and how they differ from petrol or diesel vehicles
An electric car runs on a rechargeable battery instead of petrol or diesel. The battery powers an electric motor that drives the wheels. When you press the accelerator, electricity flows from the battery to the motor — there is no engine, no gears, and no fuel tank. You charge the battery by plugging the car into a charging point, either at home, at work, or at a public charging station.
The main difference you will notice is how the car feels to drive. Electric cars are quieter than petrol cars, they accelerate smoothly without gear changes, and they have strong braking that recovers energy as you slow down. They also produce zero exhaust emissions while driving, though the electricity they use comes from the grid, which in the UK is increasingly powered by renewable sources.
The trade-off is range. Most electric cars can travel between 150 and 300 miles on a full charge, depending on the model and how you drive. Petrol cars typically go further on a tank, but you spend less time charging at home than you would spend visiting petrol stations over a year.
Key Takeaways
- Electric cars run on rechargeable batteries and produce zero tailpipe emissions, though the electricity comes from the national grid.
- Most electric cars travel 150 to 300 miles per charge, and charging at home overnight is cheaper and more convenient than public charging for daily use.
- The UK government offers a grant toward the purchase of new electric cars, though the amount and which models may have access to changes regularly.
- Charging infrastructure in the UK includes home chargers, workplace chargers, and over 50,000 public charging points run by different networks.
- Running costs are lower than petrol or diesel because electricity is cheaper than fuel and electric cars need less maintenance.
How much it costs to buy an electric car in the UK
Electric cars cost more upfront than equivalent petrol or diesel cars. A new electric car typically starts around £20,000 to £25,000 for a small model, and can reach £50,000 or more for larger or premium vehicles. A comparable petrol car would cost £5,000 to £10,000 less.
The UK government offers a grant called the Plug-in Car Grant, which reduces the purchase price of new electric cars that meet certain criteria. The grant amount and which models may have access to change regularly, so you should check the current list on the government website before choosing a car. As of recent years, the grant has covered some models but not others, and the amount has been lower than it was in previous years.
Used electric cars are cheaper than new ones, but the battery degrades over time. When you buy a used electric car, check the battery health report and the remaining warranty. Many manufacturers offer eight-year or 100,000-mile battery warranties, which often transfer to the second owner.
Where and how to charge an electric car
Charging at home is the most convenient option if you have a driveway or parking space. A home charger (also called a wallbox) costs £500 to £1,500 to buy and install, and you can claim back up to £350 through the Electric Vehicle Homecharge Scheme if you meet the criteria. A home charger typically adds 20 to 30 miles of range per hour, so charging overnight gives you a full battery by morning.
If you do not have off-street parking, you can use public charging points. The UK has over 50,000 public chargers spread across car parks, supermarkets, motorway service stations, and dedicated charging hubs. Different networks run different chargers — Instavolt, BP Pulse, Pod Point, and Charge Your Car are among the largest. You pay per charge or per kilowatt-hour, and costs vary by network and location. A full charge at a public rapid charger typically costs £10 to £20 and takes 20 to 40 minutes.
Workplace charging is free or subsidised at many employers. If your workplace offers a charger, using it during the day means you can top up without paying and without using your home electricity.
Running costs and maintenance
Electricity is cheaper than petrol or diesel per mile. Charging at home costs roughly 3p to 5p per mile, depending on your electricity rate. Petrol costs roughly 12p to 15p per mile at current prices. Over a year, this saving adds up significantly if you drive regularly.
Electric cars need less maintenance than petrol cars because they have no oil changes, no spark plugs, no transmission fluid, and fewer moving parts. Brake pads last longer because the car uses regenerative braking — the motor slows the car and recovers energy instead of relying only on friction brakes. You still need to replace tyres, check the battery coolant, and service the car according to the manufacturer's schedule, but the cost is lower.
Road tax (Vehicle Excise Duty) is free for electric cars, which saves you £150 to £190 per year depending on the vehicle type. Insurance costs are similar to petrol cars of the same size and value, though some insurers charge more because repairs can be specialist work.
Government incentives and support schemes
The Plug-in Car Grant is the main financial support for buying a new electric car. The amount and which models may have access to changes regularly, so check the government website for the current list before you buy. You cannot claim the grant yourself — the dealer applies it at the point of sale, so the discount appears in the price you pay.
The Electric Vehicle Homecharge Scheme covers up to £350 toward the cost of installing a home charger. You must own or lease an electric car, and your home must have off-street parking. You explore through an approved installer, and the grant is deducted from the installation bill.
Some local councils offer additional grants or support for electric car owners, such as free or discounted parking or access to bus lanes. Check your local council website to see what is available in your area.
How to decide if an electric car is right for you
An electric car makes sense if you have off-street parking where you can install a home charger, drive less than 200 miles most days, and can afford the higher upfront cost. Home charging means you start each day with a full battery, so daily range is rarely a problem. If you drive long distances regularly or do not have parking, a petrol or hybrid car may be more practical.
Consider your typical journey. If you commute 30 miles a day and charge at home overnight, an electric car will cost far less to run than a petrol car. If you drive 400 miles twice a week and rely on public chargers, you will spend more time charging and may find it frustrating.
Test driving an electric car is the best way to understand how it feels. Many dealerships offer test drives, and some hire companies rent electric cars by the day so you can try one in real conditions.
Common concerns about electric cars
Battery range in cold weather is a real concern. In winter, electric cars typically lose 20 to 40 percent of their range because the battery works less efficiently and you use energy for heating. If you live in a cold climate or drive long distances in winter, factor this into your decision. Most cars show the estimated range on the dashboard, and you can adjust your driving to match.
Charging infrastructure is improving but still patchy in rural areas. If you live in a city or large town, you will find public chargers easily. If you live in a remote area, check the charging networks' maps to see what is nearby before you buy.
Battery degradation is slower than many people expect. Most electric car batteries retain 80 to 90 percent of their capacity after eight years or 100,000 miles. The battery is designed to last the life of the car, and manufacturers back this with long warranties.
Frequently Asked Questions
How long does it take to charge an electric car?
At home, a full charge takes 8 to 12 hours on a standard 7kW charger. At a public rapid charger (50kW or higher), you can add 150 to 200 miles in 20 to 40 minutes. The time depends on the charger power, the battery size, and how full the battery already is.
Can I charge an electric car at a normal three-pin plug?
Yes, but it is very slow. A standard household plug delivers about 2kW, so a full charge takes 24 to 48 hours. Most owners install a dedicated home charger instead because it is faster and safer for regular use.
What happens to the battery when the car gets old?
Electric car batteries are recycled or repurposed. Some are used for stationary energy storage, and others are broken down to recover materials like lithium and cobalt. Manufacturers and recyclers are developing better processes to recover more material and reduce waste.
Do I need a special driving licence to drive an electric car?
No. If you hold a standard car driving licence, you can drive an electric car. There is no separate test or qualification needed.
Are electric cars more expensive to insure?
Insurance costs are usually similar to a petrol car of the same size and value. Some insurers charge slightly more because specialist repairs can cost more, but many now offer competitive rates for electric cars. Get quotes from several insurers to compare.
