Don't think any of the Motability installers do solar integrated chargers. They use OHME, Podpoint, BP Pulse and Easee. They sent OHME to do my install but said I didn't want it because I wanted untethered and they only do tethered, thus they contacted me and I said what I needed and arranged with Easee instead. Currently awaiting installation but pleased it's an Easee One because it comes untethered but with a cable that you can lock in to make it tethered or remove to keep in car or in the house.
