Conversions

Conversion

In general, a conversion means that you modify the characteristics of a vehicle to change either the:

  • type approval
  • or
  • the details given at registration

There are three ways in which a vehicle can be converted: 

  • converting a new and unregistered vehicle
  • converting a vehicle registered outside of Ireland before registration in Ireland
  • and
  • converting a vehicle already registered in Ireland. 

Vehicles never registered before 

A vehicle must have type-approval to be registered in Ireland. The usual evidence is a Certificate of Conformity issued by the manufacturer.

The National Standards Authority of Ireland (NSAI) issues the certificate for a new vehicle converted in Ireland or elsewhere. 

You must have the NSAI certificate with you when you go to register the converted vehicle. 

Evidence of Nitrogen Oxide (NOx) emissions must be present to proceed with registration.

Vehicles registered abroad

In cases where a vehicle was registered abroad a Declaration of Conformity and Suitably Qualified Individual declaration must be presented.

This form must be used where you have changed any of the following: 

  • the EU vehicle category
  • the number of seats
  • the number of seatbelt fittings
  • the EU Body Work Code
  • the mass in service
  • the number of doors
  • and, or
  • the number of windows.

Vehicles registered in Ireland

In most cases there is no need to make a declaration to Revenue.  You do not have to make a declaration if the vehicle category at J1 on the Vehicle Registration Certificate is A.

However, you must make a declaration if the category is B, C or D (or is blank) and you: 

  • added seats and the new total (including the driver) is nine seats or less
  • removed seats from a vehicle that had 10 seats or more and now has nine seats or less (driver included)
  • or
  • have converted the vehicle to a motor caravan. 

In these cases, you must post the Declaration of Conversion, the related SQI declaration, and other supporting documents, to:

You must include:

  • in the case of a motor caravan please provide:

    • and
    • a maximum of nine interior photographs to include: seating positions and table, sleeping accommodation, cooking facilities, storage facilities, the interior taken from the front looking rearward, and of the interior taken from the rear looking forward.

On receipt of the Declaration and supporting documentation, CVO will classify the converted vehicle, and will assess any VRT due.

If there is additional VRT, CVO will issue correspondence to you with details of the amount of VRT due along with payment methods.
