I bought my plug-in hybrid car in August and external charge point finally fitted on 30 Nov 18 after long delay waiting to get an isolation switch fitted by electricity provider. It would have been so much easier if Chargemaster could send someone round to assess the requirement at the start of the process. Instead, lots of photographs of fuseboxes, switches and locations sent, which resulted in confusion and conflicting advice. Handed from one contact to another, duplicate requests for forms or photos, requests for information already sent and then the additional cost and long wait for an isolation switch, which proved not to be necessary when the installer finally arrived. Why the fitting of a fairly simple external chargepoint (when Govt subsidised) is so complex and expensive is beyond me. Actual fitting was straightforward and the cable I ordered arrived quickly.
