Every electric car goes less far in winter. The question is how much less, and whether it matters for the way you drive. The short answer from independent testing: in typical British winter temperatures, expect something in the region of a fifth less range than the official figure, a little slower rapid charging if you do not prepare the battery, and very little inconvenience once you know the handful of habits that make the difference.
Why the official figure flatters winter driving
Official WLTP range is measured in a laboratory at around 23°C, with no heating running. A British winter morning is nothing like that. Two things happen in the cold. The battery's chemistry slows down, so it releases and accepts energy less readily. And, the bigger factor, the car spends energy keeping you warm. US government analysis attributes about two-thirds of the extra winter energy use to heating the cabin.
How much range you actually lose
| Test | Conditions | Result |
|---|---|---|
| Norwegian Automobile Federation (NAF) winter test, 2025 | -6°C to +8°C, real roads | Average 18% below official WLTP range |
| Recurrent, data from more than 30,000 US vehicles | 0°C | Average 78% of maximum range retained |
| NAF winter test, 2026, 24 cars | -7°C to -32°C, real roads | Average 38% below official WLTP range |
The NAF 2025 conditions are the closest to a normal British winter. The 2026 test ran in extreme Norwegian cold, far below anything most UK drivers see, and is the worst case rather than the expectation.
As an illustration only: a car with an official range of 300 miles would, on the 2025 test average, cover about 246 miles in cold weather. Individual models vary a great deal, so always check real-world data for the exact derivative you are considering.
The heat pump question
A heat pump warms the cabin far more efficiently than a conventional electric heater. Recurrent's data puts the benefit at around 10% more range at 0°C, although the advantage shrinks in extreme cold. If you do long winter journeys, it is worth checking whether a heat pump is standard or an option on the model you are choosing.
Charging in the cold
Batteries charge fastest when warm, at around 25°C. A cold battery at a rapid charger will take longer to reach 80%. The fix is preconditioning: warming the battery on the way to the charger, which many modern electric cars do automatically when you navigate to a rapid charger using the built-in sat nav. Your handbook will say how yours does it. In NAF's 2026 winter charging test at around -10°C, 14 of 24 cars matched their stated 10-80% charging time with preconditioning, and six beat it.
Six habits that make winter easy
- Precondition while plugged in. Warm the cabin and battery from the car's app before you leave, using mains power rather than the battery.
- Time home charging to finish just before you set off. The battery will still be warm when you start driving.
- Use heated seats and the heated steering wheel. Warming you directly uses far less energy than heating all the air in the cabin.
- Navigate to rapid chargers through the car. On many models, that is what triggers battery preconditioning.
- Check tyre pressures. They drop as temperatures fall, and under-inflated tyres cost range.
- Plan longer trips with a margin. Aim to arrive at chargers with some charge in hand rather than running low.
The UK charging network going into winter
At the end of August 2026 there were 123,677 public EV chargers across 47,810 locations in the UK, according to Zapmap. For most drivers with home charging, though, winter makes little practical difference: you leave each morning with the battery topped up.
What it means when choosing your next electric car
- Size the range for January, not July. If your longest regular journey is 180 miles, a car rated at 220 miles will feel tight in winter. Allow a margin of at least a fifth.
- Look for a heat pump and battery preconditioning. Both matter more to winter usability than a small difference in official range.
- Think about home charging first. Access to a home or workplace charger does more for winter ownership than almost anything else.
