The installation states on Motability site that up to 15 metres of cable is included from electric supply to charger, any more is chargeable and no longer a standard installation, the same applies to drilling through more than one wall.
I had the impression it was 5 meters but that was just in my head. If thats the case as is 15m, £500 to install an extra 2m of cable is scandalous and something needs to be done to stop Motability customers from being ripped off!
