Knowledgeable rep called who knew his stuff and gave me a price then and there. Turned out to be the cheapest although all three companies I contacted were within £250 of each other. Turned out when the installers came that because of the size of the slates and the method of their attachment that the job was more complicated and time consuming than had been thought, such that it took two days instead of one. However the guys doing the job just got on with it and there was never any question of the price being affected. At all times the backroom staff at EEC were at great pains to ensure that everything was by the book and that I was happy and understood fully what was going on. I also had help when I needed it in filling out the feed-in-tariff application, which went through no problem. All in all a very professional installation in all its constituent parts. I would recommend EEC to anyone contemplating having solar installed.
