I included everything related to the heating system, drilling, as well as energetically possibly relevant KNX components. I specified €49,500 for system costs and €0 for incidental costs, as these usually do not arise in a new build if you follow the definition in the information sheet. You normally don’t provide quotes right away. They are given if requested. You also don’t have to specify how the costs are composed in the application. Yesterday, I was on continuous calls with the drilling company, energy consultant, and plumber, and they all said I shouldn’t worry too much since they know that usually a layperson handles this. In case of doubt, better to include too much and have it cut than too little and have to file an objection.
