Had an entirely different experience with McNally. They were only a couple of miles away, installation booked and details confirmed only to receive an email from ProEV informing me of another installation date by them! McNally would have not contacted me and, presumably, just not turned up if I hadn’t rung them!!! So, even within the same installers, the quality of experience differs greatly.
ProEV are an outsourcing company, who outsource work to contractors on ProEV’s database. Your local installer McNally is obviously on ProEV’s list but, had their own work that day or month where they could earn more money, possibly for doing the same work privately!
Think of ProEV as an agency where contractors fallback on when a contractors work is slow or dried up but, when the contractor has thir own work…..
