New minimum temperature limits in workplaces

What are the current workplace temperature rules in the Czech Republic?

It is crucial for international managers and HR departments to be aware of a significant recent development. In response to the 2022 energy crisis, the Czech government enacted a temporary amendment, Regulation No. 303/2022 Sb., which lowered the minimum required workplace temperatures.3 This was a short-term measure designed to conserve energy. As planned, this temporary regulation expired, and the original, stricter minimum temperature limits were fully reinstated as of July 1, 2024.

This reversion creates a significant compliance risk for companies that are not diligently monitoring local legislative changes. A business that established its internal health and safety policies between October 2022 and June 2024 may have based its facility management protocols on the temporarily lowered temperatures (e.g., 18°C for offices). As of today, those policies are outdated and non-compliant, exposing the company to inspections and substantial fines.

How does Czech law classify different types of work?

Unlike some jurisdictions that apply a single temperature standard, Czech law uses a sophisticated system of "Work Classes" (Třída práce) to set temperature limits based on the physical exertion involved in a given job. This means you must first correctly classify your employees' activities to understand your specific obligations.

For most foreign companies in sectors like technology, finance, business services, and retail, two classes are most relevant:

• Class I: This covers sedentary work with minimal physical activity. It includes typical office and administrative roles, computer-based work, laboratory tasks, and the assembly of small, light objects.
• Class IIa: This class applies to work that is primarily sedentary but involves light manual activity. Examples include cashiers, drivers of passenger cars, and work at assembly lines for light parts.

Other classes exist for more physically demanding jobs, such as Class IIb for truck drivers or Class IIIa for certain types of construction work, demonstrating the law's detailed approach to employee welfare. Correctly classifying your workforce is the first step toward compliance. Our lawyers can provide legal consultations to help you classify your employees accurately.

The table below summarizes the current, legally mandated temperature ranges for these key work classes, which have been in full effect since July 1, 2024.

What specific temperatures must you maintain in your facilities?

Compliance extends beyond the main work areas to all company facilities. The government decree specifies minimum temperatures for auxiliary spaces, which are often overlooked during internal audits. These areas also saw temporary reductions in 2022-2024 and have now reverted to their original, higher minimums, reinforcing the risk of relying on outdated information.

As of 2025, you are required to maintain the following minimum temperatures:

• Changing rooms: 20°C
• Washrooms: 22°C
• Showers: 25°C
• Toilets: 18°C

Failing to maintain these temperatures, even in non-primary work areas, constitutes a breach of your health and safety obligations and can lead to penalties during an inspection.

Beyond the Thermostat: What are your other "Microclimate" obligations?

Czech labour law requires a holistic approach to the workplace environment, moving beyond simple temperature readings to encompass overall "microclimatic conditions." This demonstrates a deeper level of care for employee well-being and involves several key obligations, particularly during periods of extreme weather.

• Protective Beverages (ochranný nápoj): Employers are legally required to provide employees with specific "protective beverages" at the company's expense when they are exposed to excessive heat or cold. For work in environments where the temperature is 4°C or lower, this means providing at least half a litre of a warm beverage per shift. During heatwaves, especially for physically demanding jobs, this can mean providing mineral-infused water to replenish electrolytes lost through sweating.
• Safety Breaks: If the workplace temperature reaches extreme levels, such as 36°C, the law mandates that employers must provide additional, paid safety breaks to allow employees to cool down. These breaks are considered part of the working hours and cannot be deducted from pay or annual leave.
• Protective Equipment: For work in cold conditions, your obligations extend to providing appropriate personal protective equipment. This includes warm work clothing when temperatures fall below 10°C, and insulated gloves and footwear when temperatures are 4°C or lower.

Managing these varied requirements necessitates clear internal rules. ARROWS law firm specializes in the preparation of internal company policies that codify these obligations, ensuring your managers and HR staff have clear guidance to follow, thereby minimizing your legal risk.

Compliance Failures in Office and Administrative Environments

How can you avoid legal risk and financial penalties?

Proactive management is the most effective strategy for avoiding legal complications. Under the Czech Labour Code (Zákoník práce), employers have a fundamental and non-delegable duty to create a safe and healthy work environment for all employees. Adhering to temperature regulations is a key component of this overarching duty.

The best practice for demonstrating compliance and managing risk is to create a formal, written internal regulation (vnitřní předpis). This document should clearly outline your company's policy on maintaining workplace temperatures, the protocol for regular temperature monitoring, the procedures for extreme weather conditions (both hot and cold), and the rules for providing protective beverages and breaks. Having such a document proves to authorities that you take your obligations seriously and provides clear, consistent guidance for your managers. ARROWS excels at drafting legally required documentation that is both fully compliant and practical for your business operations.

Who enforces these rules and what happens during an inspection?

Enforcement of workplace health and safety laws in the Czech Republic is robust and taken seriously. The primary enforcement bodies are the State Labour Inspection Office (Státní úřad inspekce práce) and the regional Public Health Authorities (Krajská hygienická stanice).

Inspectors from these bodies have the authority to conduct unannounced visits to any workplace. During an inspection, they can demand to see records, take their own temperature measurements, and interview employees and managers. If they find a violation, they can impose immediate fines. These are not trivial penalties; fines for non-compliance can run into the millions of Czech crowns, depending on the severity and persistence of the violation. Facing an inspection can be a daunting experience, and having expert legal support is critical. ARROWS provides representation before public authorities to ensure your rights are protected throughout the process.

Risks for Manufacturing, Retail, and Logistics Operations

How do Czech regulations compare to other jurisdictions?

For international companies, a major challenge is navigating the different legal philosophies between their home country and the Czech Republic. The Czech system is a prime example of a continental European civil law tradition, which means its regulations are typically highly codified, specific, and leave little room for interpretation. This can be a stark contrast for managers accustomed to common law systems.

• Versus the United Kingdom: The UK's law requires a "reasonable temperature" but sets no legal maximum and only offers guidance for a minimum (16°C for sedentary work). In the Czech Republic, the limits are not guidance; they are binding law.
• Versus France: While France also lacks a single legal maximum, it has strong official recommendations and, as of 2025, new laws requiring formal risk assessments and action plans for heatwaves, bringing it closer to a more structured approach.
• Versus Poland: Poland's system is more similar to the Czech one, with legally defined minimums (18°C for offices) and active legislative work underway to establish maximum limits, reflecting a regional trend toward greater specificity.

The critical takeaway for a foreign executive is this: in the Czech Republic, compliance is not a matter of interpretation or "reasonableness"; it is a matter of objective measurement. An inspector with a calibrated thermometer can establish a violation instantly. This fundamental difference in legal culture is where many foreign companies face unforeseen risks. As an international law firm operating from Prague, European Union, ARROWS specializes in bridging this cultural and legal gap, translating not just the language of the law, but its practical application for your business.
