I recently had just the cable from the consumer unit fitted. It consisted of installing a Kenley block to split the supply (as the fuse box had no spare capacity), a new fused switch fitted next to the existing unit, the cable run under the stairs through the hall floor void and out to a porch with the cable tied up in a loop awaiting further installation. There is also a "data" cable run alongside the power cable as most chargers need to monitor the consumption throughout the rest of the house.
I haven't got an EV, or an EV charger but wanted to get the 1st phase of the installation done now. Cost £500. I now need to upgrade the main fuse to 100a but that needs to be done by the network operator. Zappi chargers seem to be popular according to the guy who did the cable install.
