Utility companies are very important for social development and citizen satisfaction. Today, we are surrounded by rapid technical changes and the arrival of new trends, the job of employees in utility companies is also changing on a daily basis and they need continuous training. In the initial part of the paper, we defined the communal activities and their tasks. Today, we are surrounded by constant learning and acquiring new knowledge and skills. Companies are dealing with survival on the market and how to be more efficient. Also, they are trying to accomplish their business goals. In order to achieve that, it is necessary for their employees to be constantly informed and educated. Education is defined through the occupation in a company and its general and specific goals. Based on the goals of each education, the content of the education is set, which determines the type of education to be applied. The main classification in the types of education is on internal and external education. Internal education is the one that takes place within a company and external is carried out outside the company and the educators are mostly professionals who are not employees of the company. Within these two types there is a classification on lecturing, audiovisual education, mentoring, training, simulation, case resolution and many others that will be explained in the paper. What is important for every company is the motivation of employees, and education is one of the motivations, because every person strives for their own personal progress and development. In this paper we have also touched upon the career development. Education itself, leads to improvement and increase in the knowledge and skills of an individual, which results in the person becoming an employee contributing more to the enterprise. Through experience and effort the person progresses. A survey was carried out in the utility companies in the Republic of Croatia, which examined the opinion of the employees on the education, how often educations are conducted in our companies and what kind of education is most frequently used; as well as what the result of education is and what progress opportunities it offers.
