Who Is Required
to Conduct an Audit?

The German Energy Services Act (EDL-G) requires all non-SME companies to conduct an energy audit every 4 years. A company qualifies as a non-SME if it meets at least one of the following criteria:

  • ≥ 250 employees (full-time equivalents)
  • ≥ €50 million annual turnover AND ≥ €43 million balance sheet total

Alternative to the audit obligation: A valid ISO 50001 certification fully replaces the audit requirement under §8 EDL-G. An energy management system (EnMS) delivers continuously better data than a 4-yearly audit.

SME Thresholds (EU Definition)

Micro Enterprise
< 10 employees · < €2 million turnover
✓ No audit required
Small Company
< 50 employees · < €10 million turnover
✓ No audit required (voluntary option available)
Medium-Sized Company
< 250 employees · < €50 million turnover
✓ No audit required (voluntary option available)
Large Company
≥ 250 employees or ≥ €50 million
⚠ Mandatory audit every 4 years

The Energy Audit Process
in 5 Steps

From commissioning to the standard-compliant report, an audit typically takes 4–8 weeks. The steps below show where Alligator provides the data foundation for your external auditor.

01
Week 1

Kick-off Meeting & Data Collection

Joint definition of the audit scope (buildings, processes, plant). Submission of energy invoices, equipment lists, and floor plans. Agreement on key contacts and the on-site inspection date.

02
Week 1–2

On-Site Inspection

Systematic walkthrough of all energy-relevant areas: building envelope, building services (heating, ventilation, cooling), production plant, and lighting. Identification of significant energy users (SEUs). Alligator provides the auditor with all historical load profile data and metering values from ongoing monitoring in exportable form.

03
Week 2–4

Data Analysis & EnPI Calculation

The Alligator platform provides the auditor with a complete digital evaluation: load profile analyses, benchmarking by sector and building type, and calculated Energy Performance Indicators (EnPIs). This eliminates time-consuming manual data collection and shortens the analysis phase.

04
Week 4–6

Measure Development & Prioritisation

Based on the Alligator analysis, your auditor develops concrete energy efficiency measures with assessments of investment, savings, and payback period — prioritised into quick wins, medium-term measures, and strategic investments.

05
Week 6–8

Final Report per DIN EN 16247

Complete, standard-compliant audit report per DIN EN 16247-1 by your auditor. Recognised by BAFA, fulfils the proof of compliance obligation under §8 EDL-G. Alligator then supports the implementation of measures with ongoing monitoring and automated savings verification.

Costs & Funding

Actual costs depend on company size, number of sites, and energy consumption structure. The figures below provide an initial orientation.

Small Company
€2,000–5,000
1–2 sites, < 100 employees
Voluntary · BAFA-fundable
Medium-Sized Company
€5,000–15,000
Multiple sites, 50–250 employees
Mandatory for non-SMEs · BAFA-fundable
Large Company
€15,000–40,000
Many sites / production facilities
Mandatory every 4 years

BAFA Funding Note: Energy audits and the implementation of energy management software (BEW Module 3) may be eligible for BAFA (Federal Office for Economic Affairs and Export Control) funding. Small companies can receive grants of up to 45%, medium-sized companies up to 35% of eligible costs. Learn more about BAFA funding →

FAQs: Energy Audit
DIN EN 16247

What does an energy audit per DIN EN 16247 cost?

Costs depend on company size, the number of sites, and the complexity of energy consumers. As a rough guide: small companies pay €2,000–5,000; medium-sized companies €5,000–15,000; large companies €15,000–40,000. BAFA funding programmes can reimburse a portion of the costs. For a concrete quote, contact a DIN EN 16247-accredited auditor.

Who is required by the German Energy Services Act (EDL-G) to conduct an energy audit?

Under §8 of the German Energy Services Act (EDL-G), all companies that are not an SME must conduct an energy audit every 4 years. A company qualifies as a non-SME if it employs ≥ 250 staff, or has ≥ €50 million annual turnover and simultaneously ≥ €43 million balance sheet total. Smaller companies may voluntarily commission an audit — for example, to access BAFA funding.

Does ISO 50001 replace the energy audit obligation under EDL-G?

Yes. A valid ISO 50001 certification (certified to ISO 50003 by an accredited certification body) fully exempts a company from the audit obligation under §8 EDL-G. The advantage: the ISO certificate remains valid for as long as the management system is maintained — unlike the mandatory audit every 4 years. In addition, the certification is eligible for BAFA funding.

How long does an energy audit take?

From commissioning to the completed final report, an audit takes 4–8 weeks depending on company size. The on-site inspection itself lasts 1–3 days. The subsequent report — which, per DIN EN 16247-1, must include the full data analysis and recommended measures — requires a further 2–4 weeks to prepare.

What happens if the audit obligation is not met?

BAFA (Federal Office for Economic Affairs and Export Control) carries out spot checks and can request submission of the audit report at any time. Non-compliance risks fines of up to €50,000 under §12 EDL-G. Beyond that, the company forgoes the identified savings potential — which in practice often amounts to many times the cost of the audit itself.
