A bit of information here which seems to support TfL’s view:
Hi everyone, This may be a little long winded as there is a response from the DVSA into my query regarding T5 converstions. I have recently done mine and sent all the evidence to DVLA for it to be re classified as a motor caravan, which they have done, however seeing that the vehicle was a van...

If the information is correct then N1 vehicles with a body type “motor caravan” are regarded as goods vehicles for speed restrictions. It is possible to have the N1 category reclassified as M1 but will require a new chassis number, and is probably not worth the effort.

Thank you for your enquiry which has now been passed to me, due to its technical nature. This has caused an extended delay in you receiving a reply, for which I apologise. Your question is more involved than you might think, but I shall try to answer all the points raised to enable you to make an informed decision on the correct registration of such a vehicle. I shall therefore start by explaining the background to the situation regarding your vehicle. In October 2007, the European Type Approval scheme for cars known as European Community Whole Vehicle Type Approval (ECWVTA) was amended by the implementation of the Recast Framework Directive 2007/46/EC. Due to this legislation, ECWVTA will extend to cover other vehicle types for the first time. The directive details the mandatory implementation dates for all categories of vehicles affected, the first being M1 passenger cars from 29th April 2009, followed by buses, coaches, vans, trucks and some special purpose vehicles at key dates between 2009 and 2014. Motor Caravans (as Special Purpose Vehicles) have required IVA testing since 29th April 2012. The Directive provides the base European legislation for the approval of vehicles that are mass produced, built in small numbers or as individual vehicles, requiring them to meet specified safety and environmental standards before they can be used on the road. The IVA scheme is a pre-registration inspection for vehicles that have not been Type-Approved to British or European standards. Since 1st May 2009 there have been two levels of IVA; Basic and Normal. Basic IVA will be applied in cases where the number of affected vehicles is expected to be low and we can accept that the very demanding safety and environmental standards of Type Approval will not be undermined. The Normal IVA will be applied in all other cases, i.e. where the number of vehicles entering service warrants Type Approval or comparable standards for key environmental and safety items. Motor Caravans will require Basic IVA testing. However, despite what you have been previously advised, it is the DVLA that will decide if a vehicle requires IVA testing, not DVSA and as such it is probably a very good idea if you contact them again, to gain an understanding of the actual situation regarding your vehicle, should you still be concerned by this. The generic understanding currently provided by the DVLA is as follows : If a panel van is converted to a Motor Caravan post registration, then it does not require additional approval. However, it should be noted that even if the DVLA accept that the vehicle now meets the definition as a Motor Caravan, the vehicle class will not change on the V5 (registration document) only the vehicle description. If the vehicle was approved as an N1 Goods vehicle it will still be listed as an N1 Goods vehicle. As you have suggested, this will have an impact on such items as speed limits applied to the vehicle and the London Congestion charge. If the intention is to have the vehicle both viewed and described as a Motor Caravan, then it must be issued with a new chassis number by the DVLA and approved as an M1 passenger vehicle under the IVA scheme. With regard to proceeding with having an IVA examination of the vehicle, with the intention of having the vehicle category changed, I have provided further information regarding the IVA scheme, which can be found by following the links below: VEHICLE TYPE APPROVAL -
