The energy certificate (ΠΕΑ): the document the seller owes you before you sign, not after

The energy certificate is the least dramatic document in a Greek purchase and one of the few whose duty runs specifically to the buyer. Article 12 of law 4122/2013 requires the seller to show it to the prospective buyer before the contract and hand it over at the transaction. Its absence is fineable up to €10,000. Its absence does not, so far as the statute goes, make the deed void — and that combination is exactly why it so often does not appear: nothing stops the sale, so nothing forces the issue, and the person who ends up without the document is the one it was written for. Rules as they stood in September 2026, checked against the ministry’s own circular and the state register.

I am not a lawyer or a certified energy inspector, and this is not legal or technical advice. It is what the published rules say and what buyers here actually run into.

What it is, and who may issue it

The Πιστοποιητικό Ενεργειακής Απόδοσης transposes an EU obligation into Greek law through law 4122/2013 (Government Gazette Α΄42, February 2013), with the calculation rules living in KENAK — ministerial decision ΔΕΠΕΑ/οικ.178581/2017, Government Gazette Β΄2367/2017, plus five technical guidelines. Only an energy inspector on the official register may issue one, and every certificate is filed on the national archive at buildingcert.gr, where anyone can verify it from its protocol number, security code and issue date.

That verification step is worth using. A certificate is a PDF, and a PDF is a thing anyone can produce; the register is the thing that makes it real. Ask for the protocol number as well as the document.

When it is required

The triggers in article 12 are: completion of a new building, completion of a major renovation, sale, and lease to a new tenant — plus public-sector buildings open to the public above 250 m², a threshold that replaced 500 m² in July 2015. Buildings under 50 m² only came into scope in January 2016, which is why a small older studio may genuinely never have had one.

The trigger buyers underestimate is the letting one. The ministry’s circular states in terms that the duty to issue a certificate and to inform the tenant applies “τόσο για τις μακροχρόνιες μισθώσεις όσο και για τις υπεκμισθώσεις και τις βραχυχρόνιες μισθώσεις” — long leases, sub-leases and short-term leases alike. Anyone buying with a view to holiday letting, which on this island is most foreign buyers, is buying into that obligation as well as the certificate’s own. The energy class also has to appear in every commercial advertisement and listing, in print, online or in an agency window, a requirement enforced since the start of 2021.

The exemption list is short and specific: places of worship, free-standing buildings under 50 m², industrial and workshop premises, temporary buildings designed for two years or less, non-residential agricultural buildings, and unconditioned structures such as parking, car washes, open-air theatres and stables. Voluntary certification is still allowed.

The nine grades, and the mistake

The scale runs Α+, Α, Β+, Β, Γ, Δ, Ε, Ζ, Η — nine grades, not the seven-band A-to-G scale most northern European buyers know from home. It is calculated as a ratio: the building’s modelled primary energy consumption divided by that of a notional reference building of the same shape and use. Β is the point where the ratio equals one — the reference standard itself — rather than a comfortable second-best.

So a buyer looking at a certificate marked Ε and reading it as “middling” has misread it badly. Most older Cretan stock — stone houses, 1970s and 1980s concrete, anything without insulation or double glazing — sits in Δ to Η, and that is not a bureaucratic verdict but a fuel bill. A house at the bottom of the scale in a village at four hundred metres is a house that will cost real money to heat in January, and the certificate is the only document in the whole purchase that tells you so before you have lived through a winter.

What it does, and does not do, at the notary

Here the honest answer is more qualified than most articles admit. Nothing in the text of law 4122/2013 imposes a general duty on the notary to cite the certificate in the sale deed, and the statute declares no nullity for its absence. The obligation is pre-contractual and it is owed to the buyer: show it, hand it over.

Two indirect routes put it into the file anyway. For property sold before completion, the ministry’s circular says the certificate is annexed to the contract. And more broadly, the certificate is a mandatory component of the Ηλεκτρονική Ταυτότητα Κτιρίου, the electronic building identity introduced by law 4495/2017 (articles 52 to 63) and mandatory on transfers since July 2021, whose certificate of completeness the notary does attach. So in practice the certificate usually surfaces through the building identity file rather than on its own account — which is fine when the building identity has been prepared properly, and a warning sign when it has not. That file sits alongside the engineer’s check as one of the two document bundles worth reading rather than skimming.

What it costs

Nothing fixed. The statutory minimum fees of presidential decree 100/2010 — €2.00 per square metre for an apartment unit with a €150 floor, and so on — were repealed by law 4409/2016, and fees have been freely negotiated ever since. Two Greek commercial sources checked in September 2026, both updated within the last month, put a 50–90 m² apartment at €60–150 and at €50–70 plus VAT respectively: roughly a factor of two apart on the same property. Houses run higher, broadly €100–300 depending on size.

There is no official figure to anchor to, so the honest range is wide: roughly €50–150 for an apartment and €100–300 for a house, and worth getting two quotes. Against the transaction it is trivial, which is another reason the seller has no real excuse.

What is changing

The recast Energy Performance of Buildings Directive, (EU) 2024/1275, was due to be transposed by 29 May 2026, and in July 2026 the European Commission sent letters of formal notice to all 27 Member States over incomplete transposition. Greece is inside that 27. What the recast will eventually do to the Greek scale, to validity periods or to minimum standards for the worst-performing stock is not stated here, because the directive’s article text was not readable from a source worth trusting. Treat the nine-grade Α+ to Η scale as current but under revision, and if you are buying a poor-rated property as a renovation project, ask your engineer what is coming rather than assuming today’s rules are permanent.

The honest downside

The certificate is a genuinely useful document that the system does not force anyone to produce. It is fineable to skip and it does not stop a sale; the fine falls on the seller and the missing information falls on the buyer; and because it usually arrives inside the building identity bundle rather than as a document in its own right, a buyer who does not ask for it by name may never see it separately at all. Add that the fine range itself is documented in a ministerial circular from November 2020 rather than in an article text readable verbatim, and that the whole regime is mid-transition against a recast directive, and the position is: ask for it, verify it on the register, read the grade properly — and do not expect anyone in the process to insist on it for you.
