Operators of systems above 70 kW
The obligation applies to operators of heating systems with a combined effective rated output above 70 kW — or, in their absence, to the owners.
Energy inspection · Above 70 kW
Mandatory energy inspectionof heating systems above 70 kW.
Under the Hungarian Energy Efficiency Act, every heating (and combined heating-and-ventilation) system operating with heat generators above 70 kW effective rated output must undergo a periodic energy inspection. BIMLine Gépész Kft. handles the entire process for you — from the on-site survey to the filing with the authority.
The deadline has passed!
For systems commissioned before 2022, the deadline for the first inspection expired on31 December 2025, and the National Climate Protection Authority has begun formally calling on defaulting operators. The procedure runs from formal notice through a grace deadline to a fine —HUF 150,000–600,000 depending on category, at a 150% increased rate for repeated non-compliance, imposed repeatedly if necessary. According to the Authority, having the inspection carried out without delay makes the fine avoidable.
Who is affected
Operators and owners — regardless of building type.
Every building type is affected
Office buildings, industrial halls, residential blocks, institutions, commercial and healthcare buildings — regardless of the building’s function.
Due every 8 years
The inspection must be repeated every 8 years; for companies subject to the mandatory energy audit it must be carried out on the occasion of — as part of — the mandatory energy audit.
New systems: within 1 year
For systems commissioned after 1 January 2022, the first inspection must be carried out within 1 year of commissioning.
Exemption — under strict conditions
Exemption may apply e.g. to systems under an energy-performance contract or a district-heating system-operation contract, and in non-residential buildings to systems above 290 kW with suitable building automation. The exemption must be proven — we survey and document the conditions.
What we inspect
From the heat generator to the operating practice.
Efficiency and condition of the heat generators (boilers, heat pumps, heating centres)
Sizing check: comparison of the installed capacity with the building’s actual heating demand — recorded on the basis of the operator’s experience
Energy efficiency of the controls, heat distribution and pumping
Assessment of the operation and maintenance practice
Recommendations: cost-effective operational and investment measures to reduce consumption
Legal background in brief
From the EU directive to the official filing.
EU basis
The Energy Performance of Buildings Directive (EPBD, 2010/31/EU, as amended by (EU) 2018/844) — mandatory inspection of heating and air-conditioning systems above 70 kW.
Hungarian rules
Act LVII of 2015 on Energy Efficiency and its implementing decrees — including Government Decree 666/2020 (XII. 28.) and ITM Decree 19/2021 (IV. 14.) — content and frequency of the inspection, qualification requirements and sanctions.
What does it cover?
The obligation is not limited to heating systems: periodic energy inspection is required for the accessible parts of a) heating systems or combined space-heating and ventilation systems with an effective rated output above 70 kW, and b) air-conditioning systems or combined air-conditioning and ventilation systems above 70 kW.
Who may carry it out?
Only a professional registered with the Hungarian Chamber of Engineers holding an energy-inspector qualification.
Exemptions
Exemption may apply to residential-building systems with continuous electronic monitoring and effective control functions; in non-residential buildings to systems above 290 kW with a suitable building automation and control system; and to systems under an energy-performance contract (Section 8 of Government Decree 122/2015 (V. 26.)) or a system-operation contract concluded with a district-heating provider. The system operator must prove the exemption; the application is submitted by an energy inspector to the Hungarian Chamber of Engineers, which adjudicates it.
Enforcement
Compliance is monitored by the National Climate Protection Authority: in the event of non-compliance it issues a formal notice with a deadline, and if the deadline passes without result it imposes a fine — repeatedly if necessary. The professional review of inspection reports and the adjudication of exemption applications are carried out by the Hungarian Chamber of Engineers.
Filing
The result of the inspection must be recorded in a report and uploaded to the official register (the “climate gas” database) — we take care of this too.
How we work

Frequently asked questions
What operators ask first.
What counts as a system above 70 kW?
Heating (and combined heating-and-ventilation) systems operating with heat generators whose combined effective rated output exceeds 70 kW. The obligation also extends to air-conditioning and combined air-conditioning and ventilation systems above 70 kW.
When was it due? Are we late?
For systems commissioned before 2022, the deadline for the first inspection expired on 31 December 2025 — operators who have not yet complied have been in default since 1 January 2026. The National Climate Protection Authority has begun notifying and formally calling on defaulting operators; the procedure runs from formal notice through a grace deadline to a fine (HUF 150,000–600,000 depending on category, at a 150% increased rate for repeated non-compliance). According to the Authority, having the inspection carried out without delay makes the fine avoidable.
How often must it be repeated?
The inspection must be repeated every 8 years. For companies subject to the mandatory energy audit it must be carried out on the occasion of — as part of — the mandatory energy audit. For new systems the first inspection is due within 1 year of commissioning. Our system tracks the next due date free of charge, and we notify you in time.
Can we be exempt from the obligation?
Yes, but the conditions are strict. In residential buildings, systems with continuous electronic monitoring and effective control functions may be exempt; in non-residential buildings, systems above 290 kW with a suitable building automation and control system. In both cases an energy-performance contract or a system-operation contract with a district-heating provider may also provide exemption. The system operator must prove the exemption: the application is submitted by an energy inspector to the Hungarian Chamber of Engineers, which adjudicates it. We survey the conditions on site and prepare the exemption application as well.
Our building is supplied with district heating — does this apply to us?
If the secondary side is operated by the district-heating provider and the system falls under a system-operation contract concluded with the provider, an exemption can be requested — the application is submitted by an energy inspector to the Hungarian Chamber of Engineers. If, however, the owner of the site has not concluded an operation contract with the district-heating provider, the inspection must be carried out and no exemption can be requested.
We are a residential condominium — what do we need to do?
For condominiums and housing cooperatives, ordering the inspection requires a resolution of the general assembly, and the recommendations of the inspection report must be presented at the general assembly following receipt. Documents related to the operation and maintenance of the system must be made available to the inspector — we assist throughout the process.
How long does it take, and does it disturb operations?
The on-site inspection takes approx. 30–40 minutes per unit, without disturbing operation — the system does not need to be shut down.
What does the price include?
Our fees follow the Hungarian Chamber of Engineers’ official fee recommendation, indexed with annual inflation. The system fee covers the full professional scope of the inspection: on-site survey, statutory report and filing with the authority. In line with the recommendation, travel is charged separately on a per-kilometre basis, but the calculator shows it in advance; it is free of charge within Budapest. There are no hidden costs. For multiple systems or sites we provide an individual, discounted quote.
