Maybe, but the case was escalated to the 'Vehicle Casework Unit', and after I received my letter I rang the same chap to discuss it with him.

He said he had further escalated it internally and this was the outcome.

He has referenced the necessary legislation VERA act 1994 part 1A subsection 1 of schedule 1...

I can see why... that's what that section of Schedule 1 says: "its status as such a vehicle, and the applicable CO2 emissions figure, are not affected by any subsequent modification of the vehicle". I doubt that when this regulation was written anyone anticipated a conversion to electric; it was probably intended to make things easier for people who make performance modifications which increase emissions.

I stated the reg, make, model and colour, and that I was planning to convert to 100% battery electric. I was firstly told that I would recieve a £10 discount as it would classify as an alternatively fuelled vehicle under the following standard.

...

After clarifying to the adviser that my conversion would not classify as such as "Electricity and Petrol/Diesel" implies that you use both ("and" not any variation of "or"), the adviser promptly told me that I would be paying standard rate.

That makes sense, because the quoted section is for use of prescribed alternate fuels, and electricity isn't fuel. The exemption should in an a different section.
