Mandatory Energy Audit (10 TJ)
The purpose of the energy audit is to identify the development of costs related to the organisation’s energy consumption, as well as operational points where unjustified energy use and additional costs occur.
During the audit, we analyse in detail the energy carriers used, consumption data and patterns, as well as operational practices influencing energy use. As a result of the analysis, we formulate concrete proposals for energy and cost saving opportunities.
Who is subject to the obligation from 01 January 2026?
Pursuant to Section 22 of Act LVII of 2015, the regulation of the mandatory energy audit has been amended compared to the previous framework. From 1 January 2026, the obligation is no longer linked to company size, but to an energy consumption threshold.
The performance of an energy audit is mandatory for all business entities whose average annual energy consumption, calculated over the three years preceding the reference year and considering all energy carriers together, exceeds 10 TJ.
The audit obligation is therefore linked to an energy consumption threshold, regardless of whether the organisation qualifies as a micro, small, medium-sized or large enterprise.
What does the obligation include?
During the energy audit we:
- provide a comprehensive overview of the organisation’s current energy consumption and energy use practices,
- identify operational points causing energy waste,
- formulate proposals based on these findings that result in energy and cost savings,
- examine energy procurement costs, related contracts and their optimisation opportunities,
- define the priorities of measures and their expected impacts.
The aim of the audit is to provide comprehensive and well-founded information on energy-related opportunities, thereby supporting conscious and responsible decision-making, without prescribing investment obligations.
How often must an audit be carried out?
According to legal requirements, the mandatory energy audit must be carried out every four years for those organisations that are subject to the audit obligation.
Exemptions and other relevant information
An organisation may be exempt from the energy audit obligation if it operates an accredited energy management system in accordance with ISO 50001.
In this case, however, annual data reporting and certificate notification obligations apply towards the Hungarian Energy and Public Utility Regulatory Authority (MEKH).

Axing Zrt.’s energy audits are not template-based reports, but expert documents built on individual energy consumption profiles, which remain valid and defensible even in the event of a regulatory inspection.
The auditor
The energy audit is performed by an independent energy auditor or auditing organisation registered with the Hungarian Energy and Public Utility Regulatory Authority (MEKH).
Axing Zrt. has held official energy auditor authorisation since 2015. Our operations are supported by stable regulatory experience and a professional relationship with the Hungarian Energy and Public Utility Regulatory Authority (MEKH).
Axing Zrt.’s NIS2 certification guarantees that the systems, data handling procedures and internal controls applied during the audit process comply with the strictest European information security requirements.
The energy audit process
Axing Zrt. prepares analyses of your organisation’s energy consumption profile based on a proven methodology.
During the audit process, special attention is paid to ensuring that the results of the examination are data-supported, documented and verifiable at a later stage:
- preparation, kick-off meeting
- data collection
- on-site survey
- development of expert recommendations
- preparation of the report and closure of the audit
During the examination, energy-related opportunities are presented in the following categories:
- operational recommendations not requiring investment,
- low-cost measures with rapid payback,
- modernisation opportunities requiring higher investment,
- examination of the integration of alternative energy sources.

Who Is Required To Carry Out An Energy Audit?
Pursuant to Act LVII of 2015 on Energy Efficiency, from 1 January 2026 all business entities whose average annual energy consumption over the three years preceding the reference year exceeds 10 TJ are required to perform an energy audit.
The determination of the obligation is based on energy consumption data, regardless of company size.
The assessment of whether the obligation applies and the correct interpretation of energy consumption data are often not straightforward; therefore, expert support is recommended when determining applicability.
Important Note – Completion Of Missed Audits
Organisations that were previously required to carry out an energy audit under earlier regulations but failed to do so must still complete the missed audit despite the change in legislation.
The amendment does not invalidate past obligations.
