Do I need an engineering signatory for minor modifications?
Vehicle modifications fall into three distinct categories:
- ‘Owner certified’ minor modifications which can be accepted for registration purposes without formal
certification.....

Examples of minor (owner certified) modifications are:
- Engine changes where the capacity increase is less than 15% above the maximum size engine available for the
vehicle .........

- Additional lighting eg fog & driving lights.
