How to Register Kit-Built Vehicles

All kit-builds must meet road vehicles regulations if they get driven on the roads. Thus, regulations governing the construction, equipment, and maintenance also apply to kit-built vehicles.

KIT-BUILT VEHICLES: There are differences between kit-builds and kit-converted vehicles.

You must follow the instructions and procedures set for new registrations. But, there are several extra documents to add to the application:

As a rule, the manufacturer supplies all the parts for a kit-built vehicle. Even so, there are several steps for individuals to complete for registration.

Note: We recommend contacting the DVLA if you need further details on what you need to provide. Follow that by sending your kit built vehicle application to:

Getting Vehicle Type Approval

The Road Vehicle Approval Regulations came into force in 2009 for the United Kingdom. Thus, having Vehicle Type Approval confirms its production samples meet or exceed specified performance standards.

Note: Kit-built vehicles do not have automatic type approval certification for the United Kingdom. That means you will need to get type approval for a kit-build.

Getting a Current Vehicle Registration Number

In some cases you can kit-built car, motorcycle, or a tricycle with a current registration number. You would need to prove that its complete construction is from new parts supplied by the manufacturer.

It is also possible to get a current registration number for a kit-built car, motorbike, or a tricycle built with one reconditioned part. That is providing:

  • You show the part got reconditioned to ‘as new‘ standard. That means it falls in line with the guidelines of the kit-build manufacturer.
  • The reconditioned part cannot be chassis, a monocoque body shell, or the frame.
DVLA Q Registration Number

The vehicle may not meet all the conditions to get a current registration number. In this case, DVLA issue Q prefix registration numbers to use on the vehicle licence plates.

Note: All vehicles must pass a relevant type approval test before they get a Q registration.
