My understanding is that manufacturers have to certify the sustainability of the EV so the more sustainable build process and materials etc the higher the grant.
This means that the government will give the grant to the manufacturer to reduce the sticker price, if this is the case then motability ops can calculate the AP on the basis that the car will be worth more at tge end of the lease as a proportion of the sales price, hopefully allowing the AP to come down
this link is from the government website , it is quite technical but the salient point for me is the first paragraph which states
”
Guidance for car manufacturers on how to apply for their vehicles to be eligible for the Electric Car Grant.
The guidance explains:
how the scheme works
vehicle eligibility
the application process”
so I take from this that the manufacturer provides evidence and receives the grant to pass on to the buyer, or provide a discount to the value of the grant
Cheers, all the very best
