The installation could not be completed on the first visit as the incoming voltage (253V) was too high for the charger range (230V-250V), but was within the tolerance of UK supply voltages (216V - 253V). We had to contact National Grid to ask them to rectify the voltage supply level. Then we had to make several calls to Pod Point to arrange a second visit to complete the installation. We were disappointed that despite paying £1000 upfront for a service, we had to waste time and energy to arrange the modification of the incoming voltage ourselves. Furthermore, it is unacceptable that you are supplying a product that does not function across the tolerance range of UK supply voltages. As EV charging point installations become more frequent, this will be a growing problem and source of frustration for customers and DNOs.
