Be aware that you will need to be able to prove that the kit is new and that you have not used any old parts. You are allowed one reconditioned part (normally the engine) and have to demonstrate that it has been rebuilt to an as new standard.
If any of this is in doubt then DVLA will assign a Q plate and then you will not be able to use a private plate on it.
Classification is Private Light Goods (PLG) and if you looking to add a private plate, it will have to be registered as new vehicle and the private plate can added at the same time. The good news is that there is no MOT’s for the first 3 years
To get my ’40 registered after the IVA test I had to submit the following to DVLA.
Proof of Name (copy of passport)
Proof of address (copy of Council tax bill)
V55/4 – Application for first tax disc
Insurance certificate (against VIN number)
Confirmation of VIN correctly stamped (letter from local garage, as cannot be done at same time as IVA!)
V267 – Declaration of a new vehicle
V627/1 – Build up Vehicle inspection Report
Build Evidence Photos
V778 – Number plate retention document (private plate I already owned)
Cheque for road tax & first registration fee
Failure is not an option, but cock-ups will happen
