32p is similar to a standard non discounted home tariff. I was paying 69p at a Gridserve point yesterday and that seems to be the going rate for a 50kw charger. Some higher output chargers are more expensive though.
Also I did a trip to Snowdonia from the south coast and every time I stopped on the motorway there were only 2 chargers which were in use. Compare that to Tesla supercharger where there were 8 or so with several free and it makes a pretty compelling case for Tesla over other EVs, or plug in hybrids.
