Vans are much simpler. Company van, minimal private usage, parked at home = £500 taxable value p.a., or roughly £130 tax p.a. (a tenner a month)
From next year, no tax at all on vans taken home (due to safety/security of vehicle) PROVIDED : no shopping except stopping for basics, 2 tip runs p.a. etc etc
So, wahey - I'm better off even if it is only a tenner a month
