What is the Energy Certificate? And why it's necessary to sell your property in 2026
What is the Energy Certificate? <\/h5>
The energy efficiency certificate<\/b> is a mandatory document that provides information about a property's energy consumption. It assesses aspects such as thermal insulation, heating or cooling systems, and rates the property from A (most efficient) to G (least efficient).<\/p>
Is it mandatory to sell a flat in Spain? <\/h5>
Yes. Since the Royal Decree 235\/2013<\/a>, this certificate is mandatory for selling or renting any property in Spain. In 2026, it remains an essential requirement throughout the buying and selling process.<\/p>
The Royal Decree 659\/2025<\/b> modifies the basic procedure for energy certification: from 23 July 2026, it is required that technicians signing certificates are registered in a central registry of competent technicians (until now, each autonomous community managed its own independently). Additionally, on 30 September 2026, an update of the recognised documents that serve as a basis for preparing, presenting, and registering the certificate comes into force. If you are going to commission one, ensure that the technician is properly qualified according to current regulations.<\/p>
The property owner is responsible for commissioning the energy certificate. This must be carried out by a qualified technician (architect, surveyor, or engineer) registered in the corresponding registry.<\/p>
It must be available from the moment the sale is advertised. The buyer has the right to know the energy efficiency of the flat before signing any contract.<\/p>
The price varies depending on the size, location, and type of property, but it usually ranges between €60 and €150 for standard flats. It is advisable to compare prices on platforms like Certicalia<\/a> or Habitissimo<\/a>.<\/p>
If you do not have the energy certificate when selling your flat, you risk fines ranging from €300 to €6,000, depending on the severity. Additionally, the buyer could claim for non-compliance with the regulations.<\/p>
Yes. The certificate is valid for 10 years<\/b>. If you sell the property after this period, you will need to renew it.<\/p>
The energy certificate<\/b> is not only mandatory in 2026 to sell a flat in Spain, but it is also a useful tool to assess a property's efficiency. Complying with this requirement will save you from penalties and facilitate the buying and selling process.
