And not forgetting the free charger and fitting, thats got to be £800-£1k. The fitter was super, we were really concerned over the electrics and the possible run for the cable, due to the awkward siting of the ancient fuse box. The guy gave us a few options, so we had an additional circuit breaker fitted, tight to the wall under a bookshelf, he then run the cabling up and over at ceiling hight, concealed in conduit. The room is basically an office/spare, so with a bit of redecorating, you wouldnt see it, then out, then down the outside wall, and fitted the omhe pro discreetly. Really well done, nice polite young guy, (a contractor) from Plug In.
