From the 1st of June 2013 a new law will take effect in Spain that obliges property owners to have an Energy Performance Certificate if they want to sell or rent their properties.
The Energy Performance Certificate (EPC), in Spanish, Certificado de Eficiencia Energética (CEE) is a document that shows how energy efficient a building or property is.
The certificate will show a rating of how energy efficient the property is from a scale from A to G. The rating ‘A’ is the most efficient and the rating ‘G’ the least.
The certificate simply gives advice on how to improve the energy rating of your property and the Energy Performance Certificate in Spain is valid for 10 years. If you decide to make changes to your property to improve the energy rating you may get your property re assessed while the EPC is still valid.
