Please can anyone recommend a make / model of home charger and a company to install it. I want a 7.4kW tethered unit to be used with a Tesla Model 3 Standard Range Plus. I don't know if my installation would be categorised as non-standard. I'll need about 25m of cable to get from my consumer unit to where my charging point will need to located on the garage wall. This is outside the range of my wi-fi signal from my router. I have tested a wi-fi powerline adaptor plugged into a mains socket in the garage to confirm that I can extend the wi-fi to the garage. 4.5metres of the cable will need to be buried under the patio. I'm happy to dig a trench myself, if someone can tell me how deep it needs to be and any other requirements. The property was built in 2003, and is the Northamptonshire area. Thanks for any recommendations.
