The steps for processing it correctly are described below:<\/p>\n<h3>1. Selection of a qualified certifying technician<\/h3>\n<p>Catalan regulations require the certificate to be issued by a recognised and accredited professional. At Arquitectura Residencial, we recommend choosing experts in energy certification who will issue a report on the current condition of the property and proposed improvements to increase energy efficiency. There is a <b class=\"ng-star-inserted\" data-start-index=\"2190\">Central Administrative Register of Qualified Technicians<\/b>, managed by the Ministry for Ecological Transition, where the details of accredited technicians can be consulted. Accredited professionals include Architects, Technical Architects, Building Surveyors and Building Engineers, Industrial Engineers, among others. The list of technicians can be consulted at the ICAEN.<\/p>\n<h3>2. Inspection and data collection at the property<\/h3>\n<p>The technician visits the flat to examine key aspects such as the heating and air-conditioning systems, the condition of thermal insulation, orientation, windows and lighting network. This inspection is essential for an accurate diagnosis in accordance with the General Procedure regulated by the Institut Catal\u00e0 d\u2019Energia (ICAEN).<\/p>\n<h3>3. Energy calculation and analysis<\/h3>\n<p>Following the inspection, recognised software tools are used to calculate the flat\u2019s energy demand and associated emissions. Based on these results, the corresponding energy label is awarded. In addition, the technician issues a report containing technically viable recommendations for improvement, including estimated payback periods and improvements in comfort and health.<\/p>\n<h3>4. Registration of the certificate<\/h3>\n<p>Finally, the energy performance certificate must be registered with the <a href=\"https:\/\/icaen.gencat.cat\/ca\/inici\/\">INSTITUT CATAL\u00c0 DE L&#8217;ENERGIA<\/a> Register of Energy Performance Certificates of Buildings of Catalonia, a mandatory step that ensures its legal validity and allows verification of the information by buyers and estate agents.<\/p>\n<h2>Documentation required to apply for the energy performance certificate<\/h2>\n<p>To facilitate the technician\u2019s work and reduce the time required for issuance, the owner must provide key documentation:<\/p>\n<ul>\n<li>Title deed or cadastral reference of the property.<\/li>\n<li>Floor plan of the flat or building, if available.<\/li>\n<li>Technical specifications of the building or dwelling.<\/li>\n<li>Details of heating, cooling and domestic hot water systems.<\/li>\n<li>Information on refurbishments carried out that affect energy efficiency.<\/li>\n<\/ul>\n<h2>Duration, validity and renewal of the energy performance certificate in Barcelona<\/h2>\n<p>The energy performance certificate has an official validity of <strong>10 years<\/strong> from the date of issue. However, it is advisable to renew it if significant refurbishments are carried out that may improve the dwelling\u2019s efficiency, such as replacing windows, improving insulation or upgrading heating systems. According to the latest amendment to the Law by Royal Decree 390\/2021, where the certificate shows a G rating, its validity is reduced to five years.<\/p>\n<div class=\"paragraph normal ng-star-inserted\" data-start-index=\"0\"><span class=\"ng-star-inserted\" data-start-index=\"0\">Obtaining a <\/span><b class=\"ng-star-inserted\" data-start-index=\"20\">G energy rating<\/b><span class=\"ng-star-inserted\" data-start-index=\"45\"> significantly reduces the period of validity of the document. Article 13 of Royal Decree 390\/2021 (in its consolidated wording) provides:<\/span><\/div>\n<ul class=\"ng-star-inserted\">\n<li class=\"paragraph list-item normal ng-star-inserted\" data-start-index=\"197\"><b class=\"ng-star-inserted\" data-start-index=\"197\">Reduced validity:<\/b><span class=\"ng-star-inserted\" data-start-index=\"221\"> While the general maximum validity of an energy performance certificate is <\/span><b class=\"ng-star-inserted\" data-start-index=\"310\">ten years<\/b><span class=\"ng-star-inserted\" data-start-index=\"319\">, where the building obtains a G rating, its maximum validity is reduced to <\/span><b class=\"ng-star-inserted\" data-start-index=\"409\">five years<\/b>.<\/li>\n<li class=\"paragraph list-item normal ng-star-inserted\" data-start-index=\"420\"><b class=\"ng-star-inserted\" data-start-index=\"420\">Responsibility for renewal:<\/b><span class=\"ng-star-inserted\" data-start-index=\"450\"> Once this five-year period has elapsed, the <\/span><b class=\"ng-star-inserted\" data-start-index=\"501\">building owner<\/b><span class=\"ng-star-inserted\" data-start-index=\"525\"> is responsible for renewing or updating the certificate.<\/span><\/li>\n<li class=\"paragraph list-item normal ng-star-inserted\" data-start-index=\"604\"><b class=\"ng-star-inserted\" data-start-index=\"604\">Purpose:<\/b><span class=\"ng-star-inserted\" data-start-index=\"614\"> This measure aims to encourage improvements in the least efficient buildings, as the owner is required to review the rating more frequently if no improvements are made to raise the label.<\/span><\/li>\n<\/ul>\n<div class=\"paragraph normal ng-star-inserted\" data-start-index=\"821\"><span class=\"ng-star-inserted\" data-start-index=\"821\">In all other cases (ratings from A to F), the certificate maintains its standard ten-year validity, unless the owner decides to update it voluntarily before that period due to changes to the building that may alter its rating.<\/span><\/div>\n<p>It is essential to provide the updated energy performance certificate to the buyer at the time of sale. Failure to do so may result in administrative penalties and legal difficulties that could affect the transaction.<\/p>\n<h2>Factors influencing the energy performance certificate and its impact on the sale<\/h2>\n<p>In Barcelona, various factors may determine the energy rating obtained, thereby influencing the perception of the property in the market and its value:<\/p>\n<h3>Construction characteristics<\/h3>\n<p>Elements such as walls, roofs, external joinery and insulation directly affect energy consumption. Older dwellings without energy upgrades tend to obtain lower ratings, which may lead to a reduction in the asking price.<\/p>\n<h3>Installations and thermal systems<\/h3>\n<p>The efficiency of the boiler, air-conditioning system and use of renewable energy sources are viewed positively. Incorporating sustainable technologies can improve the rating and attract buyers interested in long-term savings.<\/p>\n<h3>Location and orientation<\/h3>\n<p>The urban microclimate, solar orientation and surroundings also influence the energy assessment, as solar exposure and external temperature affect thermal demand. For this reason, flats within the same building, even with the same layout, may receive different ratings.<\/p>\n<h2>Practical advice for preparing an optimised energy performance certificate before selling<\/h2>\n<ul>\n<li><strong>Carry out a preliminary analysis of the property:<\/strong> identify critical points affecting energy efficiency.<\/li>\n<li><strong>Undertake minor improvements:<\/strong> such as enhancing insulation or installing double glazing.<\/li>\n<li><strong>Upgrade installations:<\/strong> replace outdated systems with certified efficient equipment.<\/li>\n<li><strong>Organise documentation:<\/strong> provide the technician with all required information to streamline the process.<\/li>\n<li><strong>Avoid delays:<\/strong> obtain the certificate in advance to prepare the documentation for the sale.<\/li>\n<\/ul>\n<h2>Personal experience in managing the energy performance certificate in Barcelona<\/h2>\n<p>As professionals with more than three generations dedicated to the Barcelona property market, at Arquitectura Residencial we have managed hundreds of energy performance certificates for our vendor clients. Our experience confirms that anticipating this process is essential to avoid delays in the sale. We have found that advising owners on technical improvements that optimise the rating not only ensures legal compliance but also differentiates their flat in the market, attracting a broader buyer profile and achieving better financial terms.<\/p>\n<h2>Legal aspects and recommendations for protecting the seller<\/h2>\n<p>From a legal perspective, providing the <strong>Barcelona energy performance certificate<\/strong> is a statutory obligation arising from Law 8\/2013 on urban rehabilitation, regeneration and renewal in Catalonia. Breach of this obligation may result in fines ranging from 300 to 6,000 euros, depending on the case.<\/p>\n<p>Furthermore, an energy performance certificate with a low rating must be accompanied by transparent information in order to avoid subsequent claims for latent defects. Arquitectura Residencial always advises its clients to complete all necessary documentation and safeguard their interests during negotiations.<\/p>\n<h2>Approximate costs and timeframe for obtaining the energy performance certificate<\/h2>\n<p>The cost of certifying a flat in Barcelona varies according to size, complexity and the professional engaged, typically ranging between 150 and 400 euros. The procedure is usually completed within one week once the data collection has been carried out. Official registration generally takes no more than three days.<\/p>\n<p>At Arquitectura Residencial, we offer certification at special rates for our clients. It is important to factor these costs into the sales process in order to plan properly and avoid unexpected issues.<\/p>\n\t\t<div data-elementor-type=\"section\" data-elementor-id=\"204113\" class=\"elementor elementor-204113 elementor-204035\" data-elementor-post-type=\"elementor_library\">\n\t\t\t<div class=\"elementor-element elementor-element-719106e e-con-full e-flex e-con e-parent\" data-id=\"719106e\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t<div class=\"elementor-element elementor-element-155b22d e-con-full e-flex e-con e-child\" data-id=\"155b22d\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-64852b5 elementor-widget elementor-widget-image\" data-id=\"64852b5\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1448\" height=\"1086\" src=\"https:\/\/arqresidencial.com\/wp-content\/uploads\/2026\/06\/fondo_cta_ca_log.jpg\" class=\"attachment-full size-full wp-image-204112\" alt=\"\" title=\"- Your trusted real estate agency in Barcelona\" srcset=\"\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-321d3f8 e-con-full e-flex e-con e-child\" data-id=\"321d3f8\" data-element_type=\"container\" data-e-type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-eac52bf elementor-widget elementor-widget-heading\" data-id=\"eac52bf\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Are you going to sell or rent a home in Barcelona and need a Certificate of Habitability or Energy Certificate?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3ea0ad4 elementor-widget elementor-widget-heading\" data-id=\"3ea0ad4\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<span class=\"elementor-heading-title elementor-size-default\">From <b>100\u20ac<\/b> + IVA*<\/span>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-178d5d6 elementor-widget elementor-widget-spacer\" data-id=\"178d5d6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9c4d27c elementor-widget elementor-widget-button\" data-id=\"9c4d27c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t\t\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/arqresidencial.com\/en\/certificates-of-occupancy-in-barcelona\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon\">\n\t\t\t\t<i aria-hidden=\"true\" class=\"fas fa-long-arrow-alt-right\"><\/i>\t\t\t<\/span>\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Request information<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3eda5df elementor-widget elementor-widget-spacer\" data-id=\"3eda5df\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"spacer.default\">\n\t\t\t\t\t\t\t<div class=\"elementor-spacer\">\n\t\t\t<div class=\"elementor-spacer-inner\"><\/div>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3d277c6 elementor-widget elementor-widget-text-editor\" data-id=\"3d277c6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Get the required documentation to sell or rent your home with a fast, professional and 100% online process.<br>*Includes the fees of the Generalitat of Catalonia<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\n<h2>FAQ \u2013 Frequently asked questions about the energy performance certificate for selling a flat in Barcelona<\/h2>\n<div class=\"faq-container\">\n<div class=\"faq-item\">\n<div class=\"faq-question\">Is the energy performance certificate mandatory to sell a flat in Barcelona?<\/div>\n<div class=\"faq-answer\">Yes.
