UK Tesla calculator
Tesla Cold-Weather Range Calculator (UK)
Winter range is where the WLTP figure lets you down. Slide to a UK winter temperature and pick your driving style to estimate the real miles you'll actually get — battery chemistry and cabin heating both take their toll.

How this is worked out
We apply a retained-range fraction at your chosen temperature to the car's WLTP range, then a driving-style factor. Estimates from published UK winter-range testing; real loss depends on speed, HVAC and preconditioning. The curve (100% at 20°C down to ~62% at −10°C) is drawn from published UK winter-range testing and is an estimate, checked 2026-07-13. Preconditioning the cabin while plugged in reduces the hit.
Questions
How much range does a Tesla lose in winter in the UK?
Expect roughly 15–25% less than the WLTP figure at UK winter temperatures (around 0–5°C), and more on fast motorway runs. Most of the loss is cabin heating and cold-battery efficiency, both of which ease once the car warms up.
Does preconditioning help winter range?
Yes. Warming the cabin and battery while still plugged in at home uses grid power rather than the battery, so you set off with a warm, efficient pack and keep more of your range.
