As said a standard install is part of the Motability package. They say a standard install is through one wall and up to 15m of cable and attach the charger to an existing wall. Anything beyond standard is for you to pay and Ohme will expect their installers to do the whole job, so you’re paying their prices even if you could get some done cheaper.
