Energy certificates when selling a home in Andalusia
For a home sale covered by Spain’s energy-certification rules, prepare a valid registered certificate and its energy label. Check the documents before marketing, rather than leaving them until signing. The certificate helps compare energy performance; it is not a promise of a particular electricity bill.

Which documents should a seller prepare?
For an existing building within the scope of Royal Decree 390/2021, article 17 requires the registered energy certificate and label to accompany the sale contract. Marketing must include the energy-rating information. Check with a competent professional whether an exception applies to your particular property; do not assume one because the home is used only occasionally.
In Andalusia, use the Junta’s energy-certificate register procedure to confirm the registration process. Ask the certifying technician what documents you will receive and who will handle registration. Keep the full certificate, label and registration evidence together.
Check validity and the property details
Article 13 sets a maximum validity of ten years, or five years for a G rating. Verify the actual issue and expiry details instead of guessing from the year you bought the property. Ask the technician whether alterations or equipment changes require an update in your circumstances.
Check that the address and description match the home you are selling. If you inherited a file containing several certificates, identify the correct unit and latest applicable version before sending material to an agent.
Read beyond the letter
Ask the technician to explain the indicators and recommendations in plain language. A rating is useful comparison information, but your actual spending also depends on occupancy, equipment use and supply tariffs. Request recent bills as separate context if available, with personal and account details removed.
For a Costa del Sol viewing, ask about shading, glazing, ventilation and the heating and cooling systems. Test how the rooms feel during your visit and flag comfort concerns for a technical inspection; a photograph of solar panels alone cannot establish a rating.
Choose improvements with evidence
Before replacing windows or equipment solely to sell, ask for a property-specific assessment and quotations. Separate a repair that resolves a defect from an optional improvement intended to reduce consumption. Consider cost, disruption and the time available before marketing.
Do not advertise a guaranteed saving or sale-price premium without evidence. Where work affects shared parts of a building, check permissions and community arrangements before proceeding. Our community-fees guide explains how to investigate shared projects and extra contributions.
Use a simple pre-marketing checklist
Locate the current documents; confirm the unit and validity; ask a competent technician about missing or outdated information; clarify registration; and supply the verified rating to the agency. Buyers should request the same file early enough to raise questions.
For new-build property, distinguish project-stage documents from completed-building documents. Ask your adviser which version is relevant to the stage of your purchase instead of comparing a proposed performance figure with an existing home as though the evidence were identical.
Connect the paperwork to your sale plan
Costa de Oro can help organise the commercial preparation of your Marbella or Costa del Sol home, alongside its presentation and valuation. Share the property’s location, type, condition and intended sale timing. A qualified technician remains responsible for the energy assessment.
Common questions
Does a good energy rating guarantee a low bill?
No. Treat the certificate and actual bills as different information; occupancy, usage and tariffs affect what you spend.
Can I assume every certificate lasts ten years?
No. Check the document itself; the national rules set a shorter maximum for G-rated certificates.
Is an energy certificate a structural survey?
No. If condition, damp or construction quality concerns you, commission the appropriate technical inspection separately.
