This paper presents the findings of research into the concept of the sector of essential services. The key objective is to gain an understanding of the nature of this sector. Essential services are fundamental to the functioning of everyday life for all. The lack of their provision will have irreversible consequences. The presented considerations argue that research on legal qualification should be based not only on the analysis of regulations but also on philosophical principles. It is essential to give due consideration to the moral implications of this issue. This approach is not exhaustive or universal. However, it aims to enhance the incomplete presentation of approaches and solutions to the problem.
