The exact date depends on when your company produced its first energy audit report. The new report must be available no later than four years later.
Info: The obligation to carry out an energy audit also applies to newly founded companies that are no longer SMEs (small and medium-sized enterprises) in their first financial year. However, they are subject to a transitional period of 20 months. The energy audit requirement also applies to companies that were founded some time ago and that are no longer SMEs.
