Prices have remained stable for home charging, but as we move through the summer months Homecharge data shows that drivers are plugging in for less time at home than in winter. In June, vehicles were plugged in for 591 minutes on average compared with a high of 669 in January.

In terms of the costs from our data, in June the average charge cost £6.42 and in January £5.85. What seems likely here is that in winter, drivers are plugging in and setting the timer to charge at off-peak rates.

May saw a notable drop in the price of public charging on the Allstar network, from 77p in March, to 72p in April and then to 65p in May. The price has stabilised at this level for a second month, and shows that drivers using our charging partners can obtain real value.

How much? Well, a fleet needing 100 kWh a week each for 100 vehicles would spend £30,800 on electricity a month at 77p per kWh. At 65p, that cost drops to £26,000 – more than £4,000 less a month*.
