Not really, Pinkster. There is no mention of the legal framework in which the vehicle wil be offered for sale. I tried googling “type approval” along with j-type electric van and you know how many reponses fitted? Zero.
An approval issued by one Authority will be accepted in all the Member States.[5] If a vehicle is produced in a very small quantity (e.g. M1 maximum 75 per year), single EU Member States can grant exception on a discretionary basis, however the validity of the Type Approval is limited to the boundaries of those Nations which concede to it.[6]
As of 2020 there is an obligation on the part of EU states to withdraw non-comliant cars from the road. Things get stricter:

The only way that Morris can produce a 1000 a year is to get type approval for it, unless Brexit. And for type approval they need a huge pile of cash and a vehicle that complies.
