The single biggest problem was the inability of the companies representatives to fully understand the complexity of the task and the challenge to the poor consumer. My first point of contact at Chargemaster was very concerned about my eligibility for an OLEV grant as it was my second charger. It transpired that I was. Then there was the whole charade of the site visit: the person who came really did not know what he was talking about and was wrong on several important issues causing me eventually to spend about £400 more than I needed to have a cable run under my house (and wired in at both ends and tested) when all that was required was someone to feed cable from the front of the house to under the stairs knowing that the Chargemaster installer would do the rest. The actual installation was fine and the installer was apologetic for the inaccurate advice I had received. However, the whole process took a couple of months and was not handled well.
