Since 1 June 2013, it has been compulsory for all homes and premises that are going to be leased or sold to have an energy certificate (Royal Decree 235/2013). This applies equally to new constructions and existing buildings/homes/premises.
The certificate must be issued by an authorised technician (engineers, engineering technicians, architects or builders). The authorised certification programs can be downloaded free of charge by technicians from the Ministry of Industry website.
In the Basque Autonomous Community, responsibility for registering energy efficiency certificates lies with the government directorate with powers in the area of energy. The task is in turn entrusted to Ente Vasco de la Energía.
Registration of new and existing constructions began on Friday 26 July 2013 and can only be performed online.
Because registration is online, certificates must be registered at the following URL, in order to obtain the energy label:
This process is entirely FREE OF CHARGE.
It is RECOMMENDED that the registration should be made by a certified technician.
