You are also advised to wait until you receive approval to start, so that you have confirmation that the basic criteria have been satisfied.
  2. You must file a request for a ‘Company passport before completing the intervention application form.
  3. You must start the investment programme within six months of the first application and complete it within four years of this date.

The start of the works is defined as the start of the construction works linked to the investment, that is, the first legally binding order for equipment, or any other commitment that makes the investment irreversible, depending on which event occurs first.

  • You must submit an application for a ‘Company passport’ before completing the intervention application form.
