Short answer 1) yes 2) no 3) no
1- Motability will pass you details over to Ohme and you will be contacted by a company, who then arrange for the charger to be installed.
2- The charger only applies to EV’s, not PHEV’s
3- The choice of charger in nearly all circumstances, is Ohme branded (Ohme Pro or Ohme E-Pod)
Is there a reason for a particular brand of charger?
