In fact i wouldn’t be surprised if they charge him if he doesn’t order another BEV/PHEV.
Mb’s policy is only to fit charge points to first time BEV users and not PHEVS. In the unlikely event they did charge, that charge would apply to PHEV’s, Hybrid and ICE, if the op chose not to order another BEV.
I’d be surprised if Motability doesn’t receive a subsidy, grant or other incentive for fitting chargers. It may be they don’t pay enough to care if they lose a few. All goes towards government targets.
The current EVHS grant currently stands at £350 including VAT Not only would Mb claim the VAT back on this, they would pay trade price for the actuall charger exluding VAT. Mb would have also negotiated pay a reduced installation rate that would also be charged VAT free.
