From 1 January 2023, it will be illegal to occupy office space in the Netherlands that does not have a C energy label.

The deadline is fast approaching and the consequences are serious.

Below you will find more information about the labelling obligation, who is subject to this obligation, exemptions and the application of the regulation.

What does the obligation involve?

The obligation is coming from the Building Decree 2012, and it indicates that all buildings, whether they are entirely or at least 50% used as office, are subject to it.

What does energy level C mean?

The energy labels are used to assess the energy performance of a building. Factors such as having a good insulation or presence of solar panels will improve the energy level. C level corresponds to a value between 190.01 to 250 kWh per square meter per year.

What happens in case of non-compliance?​

If the compliance is not met, regardless if you are a tenant or the property owner, the responsible authority will apply administrative regulations: this means imposing a penalty or closing the office.

What are the exceptions?

There are some exceptions to the energy score obligation. 

These are:

  • Usable area with less than 50% office functions, such as an industrial warehouse.
  • Buildings smaller than 100 m2.
  • Monuments.
  • Temporary buildings.


In brief, offices in the Netherlands must have an energy label C by the beginning of 2023, and enforcement will occur by imposing penalties and closing offices spaces.
