Interesting, there's a new services going up at Rugby M6 Junction 1 (about 10-15 minutes down the M6) that should be open in a couple of months. It's confirmed to have multiple chargers, I'm not sure who or what speed. But I can't imagine on a new build they would go just for a pair of 50Kwh chargers. Anyway, from Milton Keynes, to Rugby, to Coventry. M1->early M6 isn't short of chargers now (soon).
I think the Ecotricity exclusivity deal is and has been over for a while now. I'm sure most charging networks have been working hard identifying the best sites, working out plans, planning permission, getting deals with the companies that run the services. The exciting thing is work is finally underway, I expect a lot of sites to go up quite quickly as most services companies and charging networks would have made deals for dozens of sites at the same time.Not sure what you mean by that, EH have chargers on both sides of the M6 at Corley so by definition Instavolt do not have a monopoly. Maybe a challenge site by Instavolt to get a legal ruling in to break the EH stranglehold.
