With a very small dip to 23p per kWh in the first months of Q4, the average price of charging at home rose slightly to 24p per kWh, in line with the standard variable tariff of the OFGEM energy price cap.

We’re still seeing some extremely low tariffs on smart networks in off-peak periods, with 2p per kWh being the cheapest rate. Some energy providers are even offering free electricity at certain times when there's a surplus of power - when demand is extremely low and green energy production is high. However during winter, when solar is less productive and demand for energy is higher, these tariffs are rarer.

There was a consolidation in public charging costs over the Winter. Rates started to drop in Summer and Autumn last year from a high of 82p per kWh, but for Q4 they were steady at 77p per kWh, which certainly helped businesses to budget running costs more accurately.

While that’s still far higher than the cost of charging at home, if a business can claim back the 20% VAT applied to on-road energy, in net terms, the average cost of public charging for business driving is just over 64p per kWh. For a 60 kWh charge, and 200 miles of range*, that’s the difference between it costing 23ppm (or £46 in total) for the journey without claiming the VAT back, or 19ppm (and £38) if you can. Quite a difference.
