I know this has been covered before, but I just noticed this paragraph on my tax disc renewal form and thought it might provoke some thoughts. Quote " This vehicle needs an MOT certificate from 25/07/2015 but goods vehicle certificate required now if vehicle carrying goods/burden not needed by the user for accommodation purposes on the vehicle." So, the question is, are motorbikes/scooters, pedal bikes or trailers pulling them, or a car, classed as needed by the user for accommodation purposes ? Define "needed for accommodation purposes", or what comprises such. Obviously our MH is over 3.5t, hence the tax class being Private HGV. I really must stop thinking.
