Cold weather reduces Tesla range — that is a fact of battery chemistry. In typical UK winter temperatures of 2–8°C, expect to see 8–16% less range than the rated figure. At -10°C the reduction can reach 25%. The good news: Tesla's cold weather features, combined with smart charging habits, mean that most UK drivers are barely affected in everyday winter use.
How much does cold weather reduce Tesla range?
Cold temperatures affect range in two ways: reduced battery efficiency at low temperatures and increased energy demand from the heating system. The table below shows estimated range as a percentage of the rated WLTP figure:
| Temperature | Range (% of rated) | HVAC effect (additional) |
|---|---|---|
| +15°C | ~96% | −4% with heating |
| +10°C | ~92% | −8% with heating |
| +5°C | ~88% | −8% with heating |
| 0°C | ~84% | −8% with heating |
| −5°C | ~79% | −8% with heating |
| −10°C | ~75% | −8% with heating |
| −15°C | ~68% | −8% with heating |
For a Tesla Model Y Long Range with a rated WLTP range of 331 miles, you can expect around 275–295 miles in typical UK winter conditions (5–10°C with heating). At -10°C, range drops to around 225 miles.
For most UK daily driving (average commute: 20–30 miles), winter range reduction has no practical impact.
What is the Tesla cold weather package?
Tesla's cold weather package is an optional upgrade (available at order or after delivery via the Tesla app) that adds several features designed for cold climates:
- Heated rear seats — extends heating to the second row.
- Heated steering wheel — warms quickly, reduces reliance on the HVAC system.
- Heated wiper park area — prevents wipers from freezing to the windscreen overnight.
- Heated washer nozzles — stops screen wash from freezing in the nozzles.
Front seat heating is standard on all Tesla models. The cold weather package adds the rear seat heating and the ancillary heating features. In the UK's climate, the heated steering wheel alone is worth the upgrade during a cold winter — using it instead of the cabin heater can meaningfully extend range on short trips.
How to pre-condition your Tesla in winter
Pre-conditioning — warming the cabin and battery before you drive while still plugged in — is one of the most effective winter range strategies. When the cabin is warm before you unplug, you start your journey using battery power just for driving, not for heating.
Two ways to pre-condition:
- Schedule Departure — set a departure time in the Tesla app or on the touchscreen. Tesla will automatically pre-heat (or cool) the cabin and battery so the car is ready when you need it. This is the most efficient method.
- Climate On — in the Tesla app, tap "Climate" and switch it on. The car will start heating immediately using grid power (if plugged in) or battery power (if not).
Pre-conditioning while plugged in uses grid electricity, not battery. This is free if you are on an off-peak tariff and means your battery level is unaffected when you leave.

- Pre-condition on charge. Always set Schedule Departure the night before. A warm cabin reduces the demand on the battery during your journey.
- Use seat heaters, not just HVAC. The heated seats and steering wheel consume far less energy than the full cabin heater. Set the HVAC to a lower temperature (18–19°C) and use the seat heaters to stay comfortable.
- Reduce motorway speed in cold weather. At 70 mph the Model Y uses approximately twice the energy per mile compared to 50 mph. In cold weather, consider dropping to 60–65 mph on longer journeys to preserve range.
- Keep the battery above 20%. Very low state of charge in cold weather can further reduce range due to battery management. Try not to let the battery drop below 20% in winter.
- Plan shorter legs on very cold days. If temperatures drop below -5°C, plan your journey with more charging stops and shorter intervals rather than relying on maximum range.
UK winter temperatures and real-world range impact
Most of the UK experiences winter temperatures between 2°C and 8°C from November to March, with occasional dips below 0°C in January and February. Scotland and elevated areas can see -5°C or colder for extended periods.
At 5°C with the heater on, you can expect approximately 80–84% of rated range. For a Model Y Long Range (331 miles WLTP), that means roughly 270 miles of real-world winter range — more than enough for any UK daily commute and most weekend journeys.
For comparison, most UK drivers cover fewer than 30 miles per day on average. Even at -10°C with 75% range, a Model Y Long Range still offers over 240 miles of range — sufficient for any realistic UK journey without stopping.

Does Tesla have a cold weather package?
Yes. Tesla's cold weather package is an optional upgrade that adds heated rear seats, a heated steering wheel, a heated wiper park area and heated washer nozzles. Front seat heating is standard on all models. The cold weather package can be ordered at time of purchase or added later via the Tesla app.
How much range does a Tesla lose in the UK winter?
In typical UK winter conditions (5–10°C with heating), expect 8–16% range reduction compared to the WLTP rated figure. For a Model Y Long Range (331 miles WLTP), this means roughly 275–305 miles of real-world winter range. At -10°C, the reduction can reach 25%.
Should I pre-condition my Tesla before driving in winter?
Yes, absolutely — especially if you are plugged in overnight. Use the Schedule Departure function in the Tesla app to warm the cabin and battery before your usual departure time. This draws from the grid rather than the battery and ensures maximum range efficiency from the moment you drive away.
What is 'defrost' mode on Tesla?
The Defrost Car function in the Tesla app activates the front and rear defrosters, heated mirrors, heated steering wheel and seats simultaneously to clear ice and mist as quickly as possible. It can be triggered remotely from the app while the car is still parked. If plugged in, it uses grid electricity; if not plugged in, it uses the battery.
