You will need this approval if you intend to modify a vehicle. Approval is required for any alteration to a car, or part of a car from:
- the manufacturer's specifications
- its form when it was first licensed.
Certain minor modifications can be carried out without approval. However, all modifications must conform to the applicable regulations and rules.
Please visit the Agency's website for a list of the types of alterations which need approval or for information on modifications to heavy vehicles by an authorised modifier.
