Perhaps you need to consider when you want to buy a switchover system from eBay: If caught, obviously by police with a nose for chips. They will take your car milage multiply that by the amount of fuel tax you did not pay, double it as punishment and give you a set fine while they are at it.

If he's doing less than 2,500 miles per year using the biofuel, that's not the case.

According to that link it's actually if you use > 2500 litres/year, which is a lot. Assuming 40 MPG (UK), that would do you about 35k miles in a year.

Can you prove beyond a reasonable doubt that this vehicle was operated under illegal conditions for the entirety of that duration? What if it were imported? Used?

In my country the tax law has a reversed proof clause. Meaning, you are guilty until proven innocent. This clause is activated after you get caught, or even when you did not comply with administrative requirements. Other countries have similar clauses.

So in this case, if you have hard proof, meaning a proper administration, fuel tickets, etc. Which you all don't have, there is basically only a central milage database and ownership records that can hedge your damage.
