Energy Performance Certificate: What Buyers Must Check

Property portals list a "certificado energético" rating next to the photos, but few explain what the letter actually covers or what happens if it is missing. For a buyer based in the United Kingdom, used to Energy Performance Certificates at home, the Spanish version works in a broadly similar way but sits inside a different legal process, with its own notary requirements and timing.

Understanding the certificate early helps you judge renovation needs, plan conversations with the seller, and avoid surprises close to completion, when a missing document can hold up signing.

Yes. Since a change in the law in 2013, every home offered for sale or long-term rent in Spain must have a valid Energy Performance Certificate, known locally as the "certificado de eficiencia energética" or CEE. The seller, not the buyer, is responsible for commissioning it, and its registration number is supposed to appear in any advertisement, whether on a property portal, in an estate agent's window or in a private listing passed between agencies.

In practice, the rule is not always followed to the letter. Some listings quote the rating without the registration number, others mention it only once a buyer asks directly, and a small number of sellers simply have not got round to arranging it. If you are seriously interested in a property and cannot find any reference to the certificate, it is worth raising the question with the agent early, because the sale cannot be formally completed before a notary without it.

The certificate is drawn up by an independent, officially registered technician, usually an architect, engineer or qualified energy assessor, who visits the property in person. They record its construction characteristics, the type of heating and cooling systems installed, the quality of insulation and windows, and the orientation of the building, then register the result with the relevant regional energy authority, who issue the final document.

The outcome is a letter rating running from A, the most efficient, down to G, the least efficient, together with an estimate of annual energy consumption and CO2 emissions per square metre. Older properties, particularly those built before the 2000s and never substantially renovated, often sit in the lower bands, from D down to G, largely because of the construction standards of their time rather than any particular neglect by the current owner.

A low rating does not prevent a sale from going ahead, but it is a reasonable and common point for negotiation. Buyers often use a poor certificate, particularly one in band F or G, to justify asking for a lower price, or to request that the seller contribute towards the cost of improving insulation, replacing old windows or upgrading the heating system once the sale has completed. It is one of several practical levers available during the back-and-forth that precedes most Spanish property transactions.

For buyers who are planning a renovation project rather than a straightforward move-in purchase, the certificate is a useful early data point. It will not replace a proper structural or technical survey, but reading it alongside the condition of the roof, plumbing and electrics gives a fuller picture of how much work a property is likely to need before it becomes comfortable, efficient and ready to sell or let out.

Before committing to a property, it is worth going through a short checklist with the seller's agent or your own lawyer. A missing or outdated certificate rarely stops a sale outright, but it can slow down the notary appointment and, afterwards, the registration of the deed at the Land Registry.

If you are buying from the United Kingdom, the certificate itself works in exactly the same way regardless of your residence status; the requirement does not change because the buyer lives abroad. What does change is the paperwork you personally bring to the process: a valid passport, proof of income such as recent payslips or a P60, your last filed Self Assessment tax return, bank statements from the last few months, and evidence of any existing loans or mortgage commitments are the documents a Spanish lawyer, notary or bank will typically ask you for, alongside the property's own certificate and title deeds.

Since the United Kingdom is no longer an EU member state, British buyers can stay in Spain for up to 90 days in any 180-day period without a visa; longer stays or formal residence require a separate application. None of this changes whether the Energy Performance Certificate is required, but it does affect how smoothly your own paperwork moves alongside it, so it is worth having both sets of documents organised well in advance.

Spain is a relatively short flight away from most UK airports, making regular visits to a Spanish property straightforward for owners based in Britain. Many British buyers are drawn to Spain for its climate, coastal lifestyle and established expatriate communities. One practical point to bear in mind is that Spanish inheritance law differs from UK rules, so it is worth taking specific advice on how it may affect the property and one's estate. Currency movements between sterling and the euro can also affect the overall cost of purchase and ongoing expenses.

Spain and the United Kingdom have a double taxation agreement in place, and a local tax adviser should confirm how rental income or gains from Spanish property must be declared and reported to HMRC.

As the United Kingdom is no longer an EU member state, British citizens may stay in Spain for up to 90 days in any 180-day period without a visa, and must apply for a visa or residence permit for longer stays.

Since the United Kingdom uses the pound sterling (GBP) rather than the euro, buyers should factor in exchange-rate movements and currency conversion costs when paying for a property or transferring funds to Spain.
