The development of the energy sector is an essential precondition for sustainable growth of the national economy; therefore, the national energy policy is directed not only to the promotion of competition and efficient use of energy resources, but also to increased security of power supply. Because faulty operation of electrical equipment and construction or maintenance of low quality dangerous electrical equipment may cause serious risks, there is a need for professional qualification certificate stating the person’s competence in the sphere. However, not always the certificate issued by a certification body confirms the person’s compliance with the professional competence requirements laid down in the industry, whereas it protects the employee from the consequences that may result from incompetent professional performance. The study aims to analyse the main risks that can occur in the certification process of energy constructors in order to develop possible solutions for the improvement of the certification process of energy constructors. Identification of risks in the performance of the certification process of energy constructors was made using the Failure Mode and Effects Analysis (FMEA) and Delphi method. These methods were also used to find out which areas of certification service organisation need to be developed in order to improve the quality of the work performed and increase the satisfaction with the final result of the service provided.
