Why is an energy certificate mandatory?
Your basis for sales & rentals
Since 2014, an energy performance certificate has been mandatory when selling or renting a property. It shows buyers and tenants the energy efficiency at a glance – comparable to the energy label for electrical appliances. Failure to present a valid certificate risks fines and a loss of trust.
