The actual installer is the one who applies for the grant (in your case, the sub-contractor, Pro EV group Ltd) and they then should deduct it from the invoice provided for the customer (or contractor, in your case Ohme) Ultimately, Motability pay Ohme for the install and everyone’s happy.
I question that Sean. The OZEV grant for homeowners ended in 2022. The only grants available now are for residential and commercial landlords, as either a chargepoint or an infrastructure grant. See my previous post for more details 🙂
