Green cars explained: a complete guide to eco-friendly cars and insurance
The buzzword ‘green’ refers to cars that produce fewer exhaust emissions (or none at all) than standard petrol and diesel models.
You’ve probably heard of hybrid and electric vehicles (EVs), like the Toyota Prius, which uses both petrol and electric power, or the fully electric Nissan Leaf. There are also vehicles that run on hydrogen, biofuel, or LPG (liquefied petroleum gas).
The UK government aims to stop the sale of new petrol and diesel cars after 2030, so it’s a good time to make the switch
If you’re buying a new car, it’s worth understanding the differences as this can affect things like your insurance.
Types of green car
Before you buy a green car, you'll need to figure out what type you want and what'll suit you best.
Electric cars are powered by a battery and recharged by plugging into the mains electricity. They produce no emissions while driving and are almost silent when in motion, so it’s important you drive safely and are aware of pedestrians as they might not hear you coming.
There are many types of hybrid cars - a cross between petrol or diesel vehicles and electric cars with rechargeable batteries. Some hybrids don’t need plugging in, like mild hybrids (which use a small motor to assist the engine) and synergy hybrids (which run on battery power alone for short periods). These cars recharge themselves while you drive, switching between fuel and electric power during the journey. Often, they use fuel on high-speed, longer roads like motorways. Others are plug-in hybrids that can run on battery power alone for up to 40 miles.
These cars have a hydrogen fuel cell which uses water to power the vehicle through a series of chemical reactions. It’s a more sustainable way of producing power than burning fossil fuels like petrol and diesel. You can fill up on hydrogen in a similar way to petrol or diesel, but at the moment there aren’t many refill points across the UK.
LPG cars run on Liquid Petroleum Gas, much like your BBQs, camping cookers and patio heaters.. Most traditional petrol cars can be converted to run on LPG, these produce fewer harmful emissions than petrol engines and are usually cheaper to run.
A biofuel is a fuel made from harvested plants. You may have heard of this fuel from fast-food restaurants such as McDonalds who recycle their cooking oil to power vehicles. At the moment, biofuels are most often used by buses and businesses trying to cut their emissions when it comes to deliveries.

What should I know about green car insurance?
So you’re sold on the enviromental benefits of going green, but worried insuring a green car may not be so straightforward?
Car insurance companies consider many factors when calculating your car insurance. Some of these relate to the insurance group your car falls under and others to you as a driver.
When you insure a green car, there are some things you’ll need to consider that don't come into play when you insure a petrol or diesel car.
- Recovery to the nearest charge point if you run out of charge in the UK - it happens to the best of us!
- Cover for your charging cables and wall boxes (without them you'll struggle).
- Battery cover for accidental damage, fire and theft so make sure the expensive things are covered.
Embracing new technology: the rise of green vehicles
Green cars, in particular electric vehicles, are here to stay. As manufacturers roll out more affordable models and UK infrastructure improves, more people are making the switch to plug-in power. That's good news for the environment and for future generations!
If you’re considering a green car, be sure to choose specialist insurance to cover all your needs. For full protection, explore our comprehensive electric car insurance options.
