What’s Required
Large companies must conduct an energy audit every four years, covering buildings, industrial processes and transport. The audit must identify energy-saving opportunities and be performed by qualified, independent auditors. Documentation must be retained and made available to authorities. Companies may comply through an accredited ISO 50001 energy management system instead of audits.
Important Deadlines
An energy audit is required every four years.
ISO 50001 certification can replace the recurring audit.
Current Status
Fully operational since 2015.
Aligned with the EU Energy Efficiency Directive.
Continued tightening expected with the revised Directive.
Penalties for Non-Compliance
Administrative fines.
Potential impact on eligibility for public support schemes.
Requests for corrective measures or documentation.
Examples of Known Violations
As of November 2025, there are no widely publicised penalties; authorities mainly monitor deadlines and compliance declarations.
