Fastest rapid charging networks in the UK

Fastned runs the highest-power UK chargers at 400kW. But raw peak power only matters if your car can use it — most 400V EVs can't sustain more than 175kW, while 800V cars like the Kia EV6, Hyundai Ioniq 5 and Porsche Taycan can.

Will my car actually use the peak rate?

Headline charger speeds are the ceiling, not the average. The session is limited by whichever is lowest: charger max kW, your car's peak DC rate, and the car's charging curve at the current SOC. A car with a 150kW peak plugged into a 350kW charger gets at most 150kW, and only briefly — the curve typically tapers within the first 50% SOC.

800V cars (Porsche Taycan, Kia EV6, Hyundai Ioniq 5, Audi e-tron GT) hold their peak rate longer than 400V cars, so they benefit more from a 350kW charger.
