Energy deregulation – key changes for businesses and energy consumers

13 July 2026 | Knowledge, News, The Right Focus

The President has now signed the Energy Deregulation Act (UDER92). The new provisions cover both the relationships between energy undertakings and consumers, and matters relating to investment, district heating, and the administrative obligations of energy market participants. The Act introduces changes in the areas of billing, communication with consumers, grid connection, and the operations of undertakings in the energy and district heating sectors. We set out the key points to note.

Presentation of energy bills

One of the changes concerns the new manner of presenting electricity bills. On the first page of the document, suppliers are now required to include a summary containing the most important billing information. Amongst other things, consumers will be able to find therein, the total amount due, the cost of energy and its distribution, as well as the contract period. The solution is intended to enable consumers to familiarise themselves with the key billing information more quickly, without having to review the document in its entirety.

Communication with consumers

Electronic communication is to be the primary means of exchanging information between energy undertakings and consumers. At the same time, the possibility of using paper correspondence will be retained for those who do not wish to or are unable to use electronic means. The new provisions establish rules governing the use of both communication channels.

Grid connections

The changes will also affect the process of connecting new consumers to the network and commencing electricity supply. Distribution system operators are required to install meters within a period not exceeding 21 days from the date of receipt of notification of the conclusion of an energy supply agreement. This may be of significance for residential, commercial, and industrial investment projects requiring connection to the electricity network.

Fixed-term contracts

The new provisions clarify the rules governing early termination of fixed-term contracts. They concern in particular the costs associated with early termination of a contract and the scope of information to be provided to consumers regarding the financial consequences of such a decision. The aim of these changes is to establish clear rules for informing consumers of the consequences of early termination and to reduce ambiguity in this regard.

District heating

A significant proportion of the new regulations concern the district heating sector, and introduce a definition of heat and cold storage, defining the legal status of installations used for the storage of thermal energy and cold.

The amendment also covers matters relating to:

  • The use of electric boilers
  • The rules for calculating return on capital for district heating undertakings
  • The operation of high-efficiency cogeneration

The changes relate to the rules governing the operations of district heating undertakings and selected technologies used for energy generation and storage.

Heat supply for industrial purposes

The Act also contains provisions relating to the supply of heat used directly in technological processes. In certain cases, exemptions will be possible from tariffs approved by the President of the Energy Regulatory Office. Provision has also been made for a reduction of certain licensing obligations relating to the generation of heat intended for industrial purposes. These provisions concern the rules for conducting business in the field of generation and supply of heat used in technological processes.

Reduction of administrative and reporting obligations

One of the objectives of the Act is to reduce selected administrative and reporting obligations imposed on energy market participants. The changes include the simplification of certain procedures relating to conducting business in the energy market. They apply to both energy undertakings and other entities subject to sector-specific regulations.

Mandatory natural gas reserves

The Act also contains provisions concerning the system for maintaining mandatory natural gas reserves. The mechanisms enabling the maintenance of strategic reserves of this resource have been retained. The amendment also addresses selected issues relating to energy storage and the functioning of the district heating sector, including solutions concerning technologies that enhance the flexibility of the energy system.

Significance of the changes introduced

The Energy Deregulation Act covers a number of areas of energy market operations without altering its fundamental principles. It concerns, amongst other things, the manner of presenting bills, communicating with consumers, grid connection, the activities of district heating undertakings, and selected administrative obligations.

In accordance with the legislature’s stated objectives, the solutions adopted are intended to lead to the simplification of certain procedures and the adaptation of selected regulations to the current conditions governing the functioning of the energy market. The changes introduced cover both matters of significance from the perspective of end consumers and issues relating to the conduct of business and the implementation of investments in the energy sector.

NIS2 and the National Cybersecurity System Act in transport: what you need to do before October 2026

The amended Act on the National Cybersecurity System (UKSC) has been in force since 3 April 2026. For transport sector undertakings, this means a specific compliance timeline, including an obligation to register with the National Cybersecurity System (KSC) registry by 3 October 2026. Failure to do so may result in substantial financial penalties, coupled with the risk of personal liability for senior management. Not every undertaking, however, automatically falls within the scope of the new regime. Read on to find out whether your organisation is affected and what you need to do before the deadline for preparation.

Family foundations: the government has done the maths and presented the bill

Three years. That’s how long we’ve been waiting for what the Council of Ministers had seen in the data from the outset – and has now disclosed in its review of the Family Foundation Act. The document not only diagnoses the problems, but also previews substantial changes to rules that founders and their advisers treated as settled and stable. And therein lies a problem that goes far beyond tax matters. If the rules of the game are changed while the game is being played, there can be neither planning stability nor trust in the law. It is no coincidence that one of the greatest concerns among entrepreneurs considering setting up a foundation is not the level of taxation, but the stability of the legal framework – which today is once again being called into question.

What the new swiss franc act means for banks

We now have a new Act on Special Measures for the Adjudication of Cases Concerning Loan Agreements Denominated in or Indexed to the Swiss Franc. The provisions come into force 14 days after publication. So now is a good time to look at what lies ahead and what banks should be doing today.

New draft Pay Transparency Act – what has changed since December 2025?

A second version of the draft act on strengthening the application of the right to equal pay for equal work or work of equal value between men and women has now been published. It refines procedures and deadlines and introduces a new supervisory body. We have already discussed the changes affecting the recruitment stage and the three pillars of the forthcoming pay transparency framework, noting that Poland will miss the EU transposition deadline of 7 June 2026. Now, we take a closer look at the further changes, new developments and risks that have emerged in the latest, April version of the draft.

Payment Services Regulation (PSR) – between consumer protection and due diligence

The draft Payment Services Regulation (PSR) is one of the most significant elements of the reform of the EU legal framework for payment services. Its principal aim is to enhance the security of cashless transactions and to reduce the scale of financial fraud, in particular that arising from the growth of digital channels. At the same time, the new rules are intended to introduce a liability model that will not result in risk being transferred entirely to financial institutions, whilst retaining an important role for independent due diligence on the part of the user.

Banking sector overview | Banking today and tomorrow | July 2026

Under the draft legislation, banks will be required to offer existing borrowers a switch from WIBOR-based to POLSTR-based interest rates, a mechanism intended to speed up the voluntary transition of financial instruments to the new benchmark. The banking sector has responded positively to the proposal, according to Tadeusz Białek, President of the Polish Bank Association.

“Withdraw from contract here” – what next for the new button in online shops, on trading platforms and in mobile apps?

From 19 June, national legislation was to require businesses in the European Union entering into distance contracts with consumers via an online interface to provide consumers with the option to withdraw from the contract via a dedicated function/button. However, due to Poland’s delay in transposing Directive 2023/2673, which requires the use of such a button, this obligation has been postponed in our country. We look at what remote contract withdrawal entails and which transactions the new feature will apply to.

Municipal master plans – new deadline, same old challenges

On 11 June 2026, the President signed into law a bill extending the deadline for municipalities to adopt their master plans (plany ogólne). The key deadline for adopting master plans was moved from 30 June to 31 August 2026. We examine the reasons behind this change and consider what the absence of a master plan might mean for potential investors and their future projects.

Record fines and the upcoming 21st sanctions package – what should businesses expect?

The past year has brought a series of enforcement actions that clearly signal a tightening approach by the Polish customs and revenue authorities towards breaches of the sanctions regime. Importantly, businesses should already be preparing for further changes, as the European Union has announced its 21st sanctions package and updated the list of designated persons and entities. We examine the key developments and offer guidance on how to minimise the risk of non-compliance.
