Not so. Your pricing does not include servicing and maintenance as far as I can see. Thr Octopus deals DO include that.
There is also the least hassle from Octopus, they look after chargr cost and installation. Going the PCH deal, you have to look after that side as well. Its ok for YOU to do that, but for the average Joe, its just another hoop and layer of hassle to go through.
