Transferring Energy Licences and Permits in Hungary (2026): Practical M&A Checklist for Buyers and Sellers

Any energy M&A Hungary transaction, whether it involves a solar portfolio, a gas trading book or a generation asset, ultimately hinges on one question: can the target’s licences and permits survive the change of control, and at what cost in time and regulatory risk? Hungary’s licensing framework, anchored by Act LXXXVI of 2007 on electricity and overseen by the Hungarian Energy and Public Utility Regulatory Authority (MEKH), imposes consent and notification obligations that can delay or derail a deal if they are not mapped early.

With the government’s April 2026 policy reset signalling tighter scrutiny of foreign acquirers in strategic sectors, and a June 2026 deadline for MEKH’s updated regulatory concept paper, the transfer landscape is shifting in ways that demand immediate attention from deal teams. This guide delivers a step-by-step, deal-ready checklist covering licence mapping, consent triggers, timelines, due diligence red flags and SPA drafting points, the practical toolkit that is missing from every high-level market overview currently ranking for this topic.

Key Q&A at a Glance

• Can energy licences be transferred on a change of ownership? In a share sale the licence generally stays with the target company, but MEKH must be notified, and in many cases must give prior approval, when ownership, control or capital structure changes (Act LXXXVI of 2007).
• What are typical timelines? Electricity and gas trading licence transfer registrations typically take 8–12 weeks from a complete filing; renewables connection-capacity reassignments can take 12–20 weeks; nuclear permits follow bespoke ministerial timelines.
• Is regulator consent needed for connection-capacity assignment? Yes. MEKH approval is required for assignment of grid-connection capacity to a new entity, even within a corporate group restructuring.
• How do 2026 regulatory changes affect pending deals? The April 2026 government policy priorities expand FDI screening coverage for energy assets, and MEKH’s June 2026 regulatory concept paper is expected to revise licence-modification procedures, deals in market should assume longer review timelines.
• What SPA protections are market standard? Conditions precedent tied to MEKH consent, specific indemnities for licence-related losses, escrow holdbacks for pending permits and, increasingly, warranty-and-indemnity (W&I) insurance with tailored energy endorsements.
• Are Paks nuclear permits transferable? Nuclear permits are subject to a special state-approval regime under the Atomic Energy Act and require ministerial and OAH (Hungarian Atomic Energy Authority) consent; in practice they are non-transferable outside state-controlled structures.

Energy Licences Transfer Checklist: Quick Reference for Buyers and Sellers

The checklist below captures the twelve critical steps in a Hungarian energy M&A licence-transfer workflow. It is organised into three phases: pre-filing, filing and post-closing.

Pre-filing (weeks 1–4 of deal timeline)

1. Licence audit. Compile a full inventory of every licence, permit, concession and grid-connection agreement held by the target.
2. Change-of-control analysis. For each licence, determine whether a share sale triggers a notification, prior-consent or re-application obligation under applicable law.
3. FDI and competition screening assessment. Confirm whether the transaction crosses FDI thresholds (post-April 2026 expanded criteria) or merger-control filing thresholds under the Hungarian Competition Act.
4. Pre-engagement with MEKH. Schedule a confidential pre-filing meeting to confirm process, expected timeline and any informal requirements.

Filing (weeks 5–12)

5. Prepare and submit MEKH notification or consent application. Attach corporate documents, buyer financial statements, revised ownership charts and technical compliance certificates.
6. Submit parallel filings. File with the Competition Authority (GVH) and, where applicable, the FDI screening authority (Ministry of National Economy) concurrently to avoid sequential delays.
7. Environmental and building-permit transfers. For asset deals, apply to the relevant environmental inspectorate and local authority for re-issuance or novation of permits.
8. PPA and grid-contract novation. Notify offtake counterparties, TSO/DSO and grid-connection partners; obtain any required third-party consents.

Post-closing (weeks 13–16+)

9. Registration update at MEKH. Confirm new ownership data is reflected in the licence register.
10. REMIT registration update. Update the ACER REMIT registry to reflect the new beneficial owner and reporting entity.
11. Compliance review. Conduct a 90-day post-closing audit of licence conditions, tariff obligations and reporting deadlines.
12. File post-closing confirmations. Deliver closing certificates to MEKH, GVH and any other authority whose consent was a condition precedent.

Map Every Licence and Permit Before You Sign: The Energy M&A Hungary Inventory

The single most common, and most expensive, mistake in Hungarian energy transactions is entering the SPA without a complete licence map. Licences are issued by different authorities, under different statutes, with different transferability rules. The table below provides the core inventory that every deal team must compile at the start of the process.

Electricity Licences Under Act LXXXVI of 2007

The Electricity Act (Act LXXXVI of 2007, as amended) establishes the legal foundation for the electricity trading licence Hungary regime. Under this statute, MEKH issues licences for electricity trading, supply, generation and system operation. The Act prescribes that any change in the licensee’s qualifying shareholding, generally meaning the acquisition or disposal of a stake exceeding defined thresholds, triggers a prior-approval obligation. A decrease in registered capital or a corporate transformation (merger, demerger) also requires MEKH consent before the change takes effect. Failure to obtain prior approval can result in licence suspension or revocation, making this one of the highest-stakes regulatory touchpoints in any energy M&A Hungary deal.

Gas Licences: Trading, Distribution and Transmission

Hungary’s gas sector is regulated under a parallel framework (Act XL of 2008 on Natural Gas Supply), with MEKH serving as the competent authority. Gas trading licence transfer requirements largely mirror the electricity regime, but transmission licences carry additional conditions, including mandatory unbundling compliance, third-party access obligations and network-development commitments that must be assumed by the buyer. Distribution licences often overlay a municipal concession, requiring parallel consent from the local government.

Renewables and Project Permits

For renewable energy assets, solar, wind and biomass, the renewable project permit Hungary framework involves a layered set of permits. The generation permit is issued by MEKH, while building permits come from local authorities and environmental permits (EIA/IPPC) from the environmental inspectorate. Grid-connection capacity is reserved through the TSO (MAVIR) or relevant DSO and cannot be assigned to a new entity without express MEKH approval. Industry observers note that connection-capacity assignment has become a bottleneck in the renewable M&A market, with MEKH scrutinising whether the acquirer meets the same technical and financial criteria as the original applicant.

Nuclear and Paks: The Special Regime

Paks nuclear permitting operates under Hungary’s Atomic Energy Act and is supervised by the OAH (Országos Atomenergia Hivatal). All nuclear operating licences, construction permits and decommissioning obligations are subject to ministerial and OAH approval. Given the state-owned status of the Paks facility and the strategic-asset classification of nuclear infrastructure, these permits are effectively non-transferable to private or foreign buyers. Any transaction involving nuclear-adjacent assets, maintenance contracts, fuel-supply agreements, auxiliary services, must be assessed for indirect licence exposure.

Transfer Mechanics and Regulator Consent Triggers

Understanding when and how to transfer an energy licence in Hungary requires distinguishing between the two dominant deal structures: share sales and asset sales. The distinction is not merely academic, it determines whether the buyer inherits existing licences automatically or must apply for new ones.

Share Sale vs Asset Sale: Consequences for Licences

In a share sale, the target company retains its legal personality and, with it, its licences and permits. The buyer acquires ownership of the entity, not the assets directly. However, this does not mean the transaction is consent-free. Under Act LXXXVI of 2007, any acquisition of a qualifying shareholding in a licensed entity must be notified to MEKH, and prior approval is required where control changes or where the transaction would result in a decrease in registered capital. For gas licences, Act XL of 2008 imposes parallel requirements.

In an asset sale, licences do not transfer automatically. The buyer must apply for new licences in its own name, a process that can take 12–20 weeks for electricity/gas licences and significantly longer for environmental permits (which require fresh EIA applications in many cases). Asset deals therefore carry higher regulatory lead time and execution risk, but they offer the advantage of leaving behind liabilities embedded in the target entity.

MEKH Procedures and Forms

When prior MEKH consent is required, the applicant (typically the buyer, though sellers often file cooperatively) must submit a formal application including: corporate documents evidencing the transaction, the buyer’s audited financial statements, a revised ownership chart, evidence of technical capability and compliance with sector-specific requirements, and (for electricity) confirmation of REMIT registration. MEKH has 60 days from receipt of a complete application to issue a decision, though in practice the clock often restarts when supplementary information is requested. Deal teams should budget for at least one round of supplementary questions and plan for a total elapsed time of 8–12 weeks for straightforward consent applications.

Timelines, Forms and Costs for Transferring Energy Licences in Hungary

Accurate timeline planning is essential for deal structuring. The table below summarises realistic timeframes by licence type, based on recent market practice.

Electricity and Gas Trading Licence Steps

For an electricity trading licence Hungary consent application in a share sale, the filing package typically includes: the executed SPA (or a summary), buyer corporate documents (certificate of incorporation, articles, board resolutions), audited financial statements for the prior two years, a revised beneficial-ownership chart, evidence of technical personnel and REMIT registration, and payment of the applicable MEKH administrative fee. Gas trading licence transfers follow an analogous process under Act XL of 2008. Filing fees are published on the MEKH website and are generally modest (in the range of HUF 100,000–500,000, depending on licence category), though legal preparation costs substantially exceed the regulatory fee.

Renewables Connection and Grid Capacity Transfer

Grid-connection capacity reassignment is the most time-sensitive element in renewable energy M&A. MEKH assesses whether the acquiring entity meets the technical, financial and organisational criteria that were the basis for the original capacity reservation. If the buyer cannot demonstrate equivalent capability, MEKH may require a fresh application, effectively resetting the queue. Deal teams should commence the MEKH pre-engagement process at least four weeks before the anticipated filing date to identify and resolve potential shortfalls in the buyer’s qualification package.

Nuclear and Strategic Projects, Extended Timelines

Transactions touching nuclear or strategically classified assets follow ministerial-level approval processes that operate outside MEKH’s standard procedural timelines. For Paks nuclear permitting, the OAH and the responsible ministry conduct independent safety, security and policy reviews. Timelines are measured in months rather than weeks, and early indications suggest that post-April 2026 government policy will apply heightened scrutiny to any transaction, even involving ancillary service contracts, that could affect nuclear supply-chain integrity.

Energy M&A Due Diligence Hungary: The Priority Checklist

Due diligence for energy assets in Hungary must go beyond standard corporate D/D to cover licence-specific, regulatory and technical layers. The following checklist identifies priority items and red flags that should trigger enhanced investigation or, in some cases, deal-walkaway conversations.

• Licence validity and renewal dates. Confirm each licence’s current validity period and whether renewal applications are pending or overdue. A licence expiring within 12 months of projected closing is a material risk.
• Compliance history. Request the target’s correspondence file with MEKH for the past three years. Any unresolved compliance notice, penalty proceeding or audit finding should be escalated.
• Outstanding grid-connection obligations. Verify that capacity reservations are current, that milestone deadlines have been met and that no forfeiture risk exists.
• PPA assignability. Review power purchase agreements for change-of-control clauses, consent requirements and termination triggers. Counterparty consent may take 4–8 weeks to obtain.
• Environmental permit status. Confirm IPPC/EIA permits are valid, conditions are being met and no enforcement action is pending.
• EU REMIT registration and reporting. Verify the target’s registration in the ACER REMIT registry and confirm that all transaction-reporting and inside-information obligations are current.
• Third-party consents. Identify any contracts (fuel supply, O&M, lease agreements for land or equipment) that contain change-of-control clauses requiring counterparty consent.
• FDI exposure. Assess whether the target’s activities fall within the scope of Hungary’s expanded FDI screening regime (post-April 2026 thresholds).

Walkaway triggers: licence revocation proceedings in progress; connection capacity at risk of forfeiture before closing; uninsurable environmental liabilities; or FDI screening authority signalling likely prohibition.

Deal Structuring, SPA Drafting and Remedies

Energy M&A in Hungary requires SPA provisions that are specifically calibrated to regulatory risk. Generic acquisition agreements, even those used for other regulated sectors, frequently fail to address the interlocking filing requirements and consent-timing pressures that characterise energy licence transfers.

Conditions Precedent and Interlocking Filings

The SPA should include clearly sequenced conditions precedent (CPs) covering:

• MEKH consent, for licence transfer or change-of-control approval.
• GVH merger clearance, where thresholds are met.
• FDI screening clearance, where applicable under the expanded post-April 2026 regime.
• Third-party consents, PPA counterparties, grid operators, landlords.

A well-drafted CP clause should specify a long-stop date that accounts for the cumulative worst-case timeline across all parallel filings. For a transaction requiring MEKH consent, GVH clearance and FDI screening, a long-stop date of 6 months from signing is typical; 9 months is prudent where nuclear-adjacent assets are involved.

Reps, Covenants and Escrows

Market-standard representations for Hungarian energy deals should include the following:

• “The Seller represents that all licences listed in Schedule [X] are valid, in full force and effect, and no event has occurred that would entitle MEKH or any other authority to suspend, revoke or materially modify any such licence.”
• “The Seller covenants that between signing and closing it shall not take any action, or fail to take any action, that would result in a breach of any licence condition or trigger a review by MEKH.”
• “The Buyer shall deposit [amount] into an escrow account, to be released upon confirmation by MEKH that the post-closing registration has been completed and no objection has been raised within 60 days of closing.”

Specific indemnities should cover losses arising from licence revocation, connection-capacity forfeiture or environmental-permit invalidity discovered post-closing.

W&I Insurer Expectations for Energy Assets

Warranty-and-indemnity insurance is increasingly used in Hungarian energy transactions, but insurers apply sector-specific scrutiny. Industry observers note that W&I underwriters typically require a full licence-mapping table as part of the underwriting submission, expect to see evidence of the MEKH pre-engagement process and may exclude coverage for known regulatory risks (such as pending MEKH proceedings or disputed connection-capacity allocations). Buyers should engage their W&I broker no later than the term-sheet stage to ensure that policy terms align with the regulatory-risk profile of the target.

Pre-Filing Strategy and Engagement with Authorities

Early, structured engagement with MEKH and other relevant authorities is one of the most effective risk-mitigation tools available to deal teams in energy M&A Hungary transactions. A well-executed pre-filing strategy can shorten review timelines, reduce the risk of supplementary-information requests and identify potential objections before they become deal-blockers.

• Timing. Initiate a confidential pre-engagement with MEKH at least 4–6 weeks before the anticipated filing date. For transactions requiring parallel GVH or FDI filings, coordinate timing so that all applications are submitted within the same 2-week window.
• Pre-read packs. Prepare a concise summary of the transaction (anonymised where necessary), the licences affected and the proposed post-closing ownership structure. MEKH case handlers value early visibility of complex structures.
• Confidentiality. MEKH staff are subject to confidentiality obligations, but deal teams should confirm treatment of commercially sensitive information in writing before the pre-engagement meeting.
• Simultaneous notifications. Where FDI screening, competition filings and MEKH consent are all required, file simultaneously wherever procedural rules permit. Sequential filing adds 6–12 weeks of avoidable delay.

2026 Regulatory Changes in Energy M&A Hungary, What to Watch

Two developments in 2026 are reshaping the regulatory landscape for energy licence transfers in Hungary. Deal teams with transactions in market or under negotiation should take immediate steps to assess their exposure.

April 2026, expanded FDI screening. The government’s April 2026 policy priorities broadened the scope of Hungary’s FDI screening regime to cover additional energy sub-sectors, including renewable-energy project companies and electricity storage assets. Transactions that would previously have fallen below the screening threshold may now require ministerial notification. The likely practical effect is an additional 4–8 weeks of review time for affected deals.

June 2026, MEKH regulatory concept deadline. MEKH is expected to publish an updated regulatory concept paper by the end of June 2026, covering, among other topics, revised procedures for licence modifications, transfers and renewals. Early indications suggest the concept paper will propose standardised filing forms, shorter statutory review periods and clearer criteria for connection-capacity reassignment. Until the concept paper is finalised, deal teams should assume current (longer) timelines and budget for potential procedural changes taking effect in Q3–Q4 2026.

Immediate actions for deals in market:

• Re-assess FDI screening exposure under the expanded April 2026 criteria.
• Build a timeline buffer of 4–8 weeks into long-stop dates to accommodate potential procedural changes.
• Monitor MEKH publications for the June 2026 concept paper and adjust filing strategy accordingly.
• Brief W&I insurers on the evolving regulatory position to avoid coverage gaps.
