With your campervan conversion complete and re-registered as a ‘Motor Caravan’ according to the DVLA campervan conversion criteria. You will still have to follow the rules of the road like any other vehicle driver.
All road vehicles must be safe to drive on the road and therefore you will need a campervan or motorhome MOT. Your motorhome will require an MOT test every year if over 3 years old, just like any other vehicle.
‘Motor Caravans’ or re-registered campervan conversions are subject to class IV MoT test whereas goods vehicles between 3000 and 3500 KG are subject to a class VII test.
Also, Motor Caravans are subject to the same criteria as a normal car when tested. Be sure to check whether any test centre has the facility to test your campervan as some do not have the room or a big enough lift suitable for larger vehicles.
