How pricing works here

Time-of-use pricing: the rate depends on the clock. Charging is cheaper off-peak and costs more during peak hours.

  • 00:00–04:00: Tesla £0.23, others £0.33
  • 04:00–08:00: Tesla £0.23, others £0.33
  • 08:00–20:00: Tesla £0.48, others £0.70
  • 20:00–24:00: Tesla £0.36, others £0.51

The data also holds a plain fallback rate. It isn't the headline, because the published schedule above takes precedence.

Idle / congestion fee: £0.50/min once the car is done charging and the site is busy.
