In the EU countries different quality concepts and certification procedures exist in the building and installation process, next to standards and installation guidelines. Different existing certification schemes for heat pump installers in the participating countries have been analysed in the European SEPEMO-project. As certification is one of the important topics in the European Renewable Energy Directive, important questions are discussed such as: mandatory or voluntary certification, company or personal certification, methods for auditing and training courses. On certification for heat pumps other European directives have to been taken into account as well as legislative measures on local level for ground source systems. Also the question is raised if certification only is sufficient to guarantee the performance, as in a well designed and tuned installation the performance gets more and more dependent on the quality of the building envelope.
