Know what you are buying
A battery-electric vehicle (BEV) runs on electricity and needs charging. A full hybrid combines an engine and electric motor but does not plug in. A plug-in hybrid (PHEV) can cover some journeys on electricity, provided you charge it regularly; after its battery is depleted it uses its engine.
Choose around your charging access and longest regular journey, not a headline range alone. A buyer with reliable home or workplace charging has a different cost equation from someone dependent on rapid public chargers.
- Map a typical week of driving, not just a longest annual trip.
- Check parking and charging access at home, work and usual destinations.
- Get insurance quotes for the exact vehicle.

Understand real-world range
The official range is a standardised comparison figure, not a guarantee for every trip. Speed, temperature, hills, tyres, load and cabin heating can all change energy use. Allow a comfortable margin for winter and motorway travel.
Battery capacity is measured in kilowatt-hours (kWh); efficiency is often shown as miles per kWh. A larger battery can offer more range, but the car's efficiency and your driving matter too. Compare the usable battery capacity and charging curve, not just a peak charging number.

Plan charging before purchase
Home charging is often convenient, but installation suitability, tariffs and grants depend on your property and circumstances. Public AC charging commonly suits longer stops; DC rapid charging suits journeys but prices vary by network, time and location. Check the car's AC and DC charging limits and compatible connectors.
Ask whether the correct charging cables are included. Before relying on a route, check live charger availability, payment method and pricing in a current chargepoint service. GOV.UK maintains guidance on public charging and grant eligibility.
- Check whether off-street parking and an approved installation are possible.
- Compare the car's charging capability with nearby chargers.
- Budget using the prices you will actually pay, including public charging.

Inspect a used electric car
Do all the normal used-car checks, then examine the charge port, included cables, charging operation, warning messages and tyres. Ask for battery-health or state-of-health information where the manufacturer or a qualified specialist can provide it. The displayed range alone is an estimate influenced by recent driving and weather, so it is not a battery-health certificate.
Confirm the remaining battery warranty for that exact car, including age, mileage, capacity threshold and transfer conditions. Check whether any battery lease applies to an older model. During a test drive, try regenerative braking and the heating and cooling system.
- Confirm both AC and DC charging work if practical.
- Request battery-health evidence and warranty documentation.
- Inspect tyres, brakes, underbody and service history.

Check current costs and incentives
Compare purchase price, insurance, depreciation, charging and maintenance together. Home and public charging can produce very different running costs. Vehicle tax, purchase grants and chargepoint schemes change, and eligibility can depend on the car, buyer and property.
Use the official pages below for the latest eligibility and amounts. Do not assume a grant advertised for new cars applies to a used car.
