Navigating the Changes to Danish Work Hour Registration Law LOV 89 in 2026

Denmark's work hour registration law LOV 89 has been reshaping how employers across the country track and document working time since it came into force following the landmark Court of Justice of the European Union ruling in the CCOO case, which obliged EU member states to ensure objective, reliable, and accessible systems for measuring daily working hours. For Polish workers employed on Danish construction sites, in logistics, or through staffing agencies, understanding exactly what LOV 89 demands in 2026 is not optional, it is a legal obligation that sits on both the employer's desk and, in many cases, the worker's own smartphone.

Why LOV 89 Matters More Than Ever in 2026

The Danish Working Environment Authority, known as Arbejdstilsynet, has been intensifying its oversight of working time records across all sectors. The law requires that every worker's daily hours are logged in a way that is accessible, tamper-proof, and retrievable for a defined retention period. This is not a bureaucratic formality. Employers who cannot produce complete records during an inspection face serious consequences, and those consequences have been getting harder to ignore. If you want a clear picture of what non-compliance can cost, the details on fines for missing time registration in Denmark 2026 are worth reading before you assume the risk is manageable.

For Polish staffing agencies sending workers to Danish clients, the stakes are doubled. The agency is typically the formal employer, which means the registration obligation rests with the agency even when the worker is physically on a client's site. Getting this wrong can damage commercial relationships and trigger regulatory action on both sides of the border.

Step 1: Confirm Who Is Covered

LOV 89 applies to virtually all employees working in Denmark, regardless of their nationality or the country in which their employer is registered. This includes posted workers arriving from Poland under an A1 certificate. If you are a Polish worker or a Polish employer sending staff to Denmark, the posting arrangement does not exempt you from Danish working time registration rules. The EU Working Time Directive, which LOV 89 implements into Danish law, sets a floor of protection that applies across the single market. For a full picture of posting formalities, including RUT registration requirements, the guide on the A1 Certificate and RUT Registration for Polish Workers 2026 covers the parallel compliance steps you need to handle at the same time.

There are limited exceptions, certain senior managers and workers whose total working time cannot be measured or determined in advance may fall outside the scope, but these exceptions are narrow and should not be assumed without legal advice. When in doubt, register.

Step 2: Gather the Required Documentation

Before setting up any registration system, an employer needs to have several things in order. The employment contract must clearly state the agreed working hours or the reference period used to calculate average hours. Danish law and the EU Working Time Directive both set limits on average weekly working time, and the contract is the starting point for showing that those limits are being respected. Alongside the contract, you will need a written description of the time-registration system itself, how it works, who is responsible for entries, and how records are stored.

For posted workers, the employer should also have the A1 certificate and RUT registration confirmation readily available, since Arbejdstilsynet inspectors may ask for these alongside the time records.

Step 3: Choose and Set Up a Registration System

The law does not prescribe a specific technology. Paper timesheets, spreadsheets, dedicated apps, or integrated payroll systems are all acceptable provided they meet the core criteria: the record must be objective, reliable, and accessible. In practice, most employers operating across multiple sites have moved toward digital solutions that allow workers to clock in and out via a mobile device, with the data stored centrally.

Consider a hypothetical example: an agency employing thirty Polish workers across several construction sites in the Copenhagen area might use a cloud-based app where each worker logs start time, break duration, and end time daily. The project manager receives an automatic summary each week, and the data is retained on a server accessible to Arbejdstilsynet if required. This kind of setup satisfies the spirit and the letter of LOV 89 without creating a heavy administrative burden.

Arbejdstilsynet publishes guidance on its official website at at.dk that describes what an adequate system looks like. Checking that guidance before finalising your setup is a sensible first step.

Step 4: Implement Daily Registration and Train Your Staff

A system that exists on paper but is not used daily is worthless during an inspection. Once the system is in place, every worker must understand how to use it and why it matters. For Polish workers who may be new to Danish workplace culture, a brief onboarding session, ideally in Polish, explaining the registration process reduces errors significantly. Employers operating in competitive labour markets are already discovering that clear communication about rights and obligations is part of what makes a posting attractive, a point explored in more depth in the article on how Polish staffing agencies attract workers to Denmark in 2026.

Managers on site should carry out periodic spot-checks to ensure entries are being made in real time rather than reconstructed at the end of the week. Reconstructed records are far more likely to contain errors and far harder to defend if questioned by Arbejdstilsynet.

Step 5: Retain Records and Prepare for Inspections

Danish law requires that time records be kept for a defined retention period after the employment relationship ends. Employers should store records in a format that can be produced quickly on request. During an Arbejdstilsynet inspection, being able to pull up a complete, clearly formatted log for any given worker on any given day is the single most effective way to demonstrate compliance.

If your business also has obligations in Poland, for example, if you run a Polish staffing agency with employees posted to Denmark, you should be aware that Polish labour inspectors from the Państwowa Inspekcja Pracy (PIP) may also request documentation related to posted workers. Keeping records that satisfy both Danish and Polish requirements simultaneously is achievable with a well-designed system. The Polish government's official employment and social affairs portal at gov.pl provides information on Polish employer obligations for posted workers that is worth cross-referencing.
