Thanks wpapau and Chuq for sowing some doubt in my mind.
I checked with my council contact again and you are right, she didn't know the difference between destination and superchargers.
She knows the difference now and will check for me what is coming and where.
If they are destination chargers for Lava St, which I now suspect they are, then she will try to find out where the super charger is going.
I must say though the Lava St site has a very good 3 Phase power supply across the road. The whole main street power feeds in at this point
