The energy certificate you need to sell a home in Europe
Founder of Seeki.eu. Writes about buying, renting and selling across European property markets, drawing on the portal's own listings data.
Almost every seller in Europe hits the same wall at the same moment: the listing is written, the photos are done, and the portal will not publish without an energy certificate that takes a week to obtain. It is the single most common reason a private sale starts late. Worse, the rules are being rewritten across the continent right now, and several of the numbers that circulate on estate-agency blogs are simply wrong.

This area is changing faster than usual (see below), and validity, cost and penalties turn on your region and your property.

Why this is changing right now
According to the European Commission, on 15 July 2026 it opened infringement procedures against all 27 Member States, sending each a letter of formal notice for failing to fully transpose the recast Energy Performance of Buildings Directive, Directive (EU) 2024/1275, whose transposition deadline had passed on 29 May 2026. Each government has two months to respond before the Commission can move to a reasoned opinion. Every country in this article is behind, and the directive requires the energy performance indicator and class to be stated in advertisements for any building offered for sale or rent, online and offline, including on property search portals.
Several markets have already moved. Austria's amended certificate law applies from 1 July 2026: the overall efficiency factor (fGEE) drops out of advertisements, the heating and final energy demand figures stay, a new A to G class joins them in place of the old A++ to G scale, and a valid certificate is now needed to extend an existing tenancy as well. In the Netherlands, from 29 May 2026 the exemption that had covered protected monuments is gone, so a listed building now needs a label to be sold, let, or have its lease renewed, according to the Cultural Heritage Agency (Rijksdienst voor het Cultureel Erfgoed). Assume anything below can shift within a year.
For a seller the practical consequence is narrow and worth stating plainly: the rating is becoming a mandatory field in the advert itself, in every market, on every portal. That is one more thing to get right on each form you fill in, which is a good reason to build the listing once somewhere that carries the rating with it. Where to list, and what each portal charges a private seller, is mapped in where private sellers can list property in Europe.
What each market calls it, and how long it lasts
| Market | Certificate | Validity | Rating required in the advert |
|---|---|---|---|
| Czechia | průkaz energetické náročnosti budovy (PENB) | 10 years | Yes |
| Slovakia | energetický certifikát | 10 years max | Yes, where a certificate exists, as the integrated performance indicator |
| Poland | świadectwo charakterystyki energetycznej | 10 years | Yes, where a certificate exists, as numeric indicators rather than a letter class |
| Hungary | energetikai tanúsítvány | 5 years | Yes, unconditional |
| Austria | Energieausweis | 10 years | Yes, the class plus heating and final energy demand |
| Germany | Energieausweis | 10 years | Yes, where a certificate exists |
| Netherlands | energielabel | 10 years | Yes, and since May 2026 for monuments too |
| Belgium (Flanders) | energieprestatiecertificaat (EPC) | 10 years for a dwelling | Yes, plus address or certificate code, and the renovation duty at label E or worse |
| Belgium (Wallonia) | certificat PEB | 10 years max | Yes, plus the unique certificate number |
| Belgium (Brussels) | certificat PEB | 10 years | Yes |
| France | diagnostic de performance énergétique (DPE) | 10 years | Yes, energy and carbon class |
| Spain | certificado de eficiencia energética | 10 years, but 5 for class G | Yes |
| Portugal | Certificado Energético | 10 years | Yes |
| Italy | attestato di prestazione energetica (APE) | 10 years max | Yes, indices and class |
Validity is not always the whole story. In Czechia, Slovakia and Poland a certificate lapses early if works change the building's energy performance. In Italy the ten years is a ceiling rather than a guarantee: the certificate is conditional on the mandatory heating and cooling maintenance checks being carried out, and if one is missed the certificate expires on 31 December of the following year. In Hungary a standing rule says that a certificate issued before a change in the calculation method can be used for a sale or a letting only until the sixtieth day after that change. The method changed on 1 November 2023, the same day the shorter validity took effect, so existing certificates stopped being usable for a sale at the end of that year. They were not cancelled, but they could no longer carry a transaction, and nothing grandfathered them.
What it costs, and why nobody can tell you precisely
This is the field where you should distrust confident numbers, including ours. Across all fourteen jurisdictions here, exactly two publish an official price:
- Portugal regulates the registration fee by ministerial order (Portaria n.º 138-H/2021): €28.00 for a T0 or T1, €40.50 for a T2 or T3, €55.00 for a T4 or T5 and €65.00 for a T6 and above, plus VAT. The order indexes those amounts to inflation each year, though the 2021 figures are still the ones being charged. The assessor's own fee is separate and unregulated.
- Brussels publishes an indicative minimum of €210 including VAT for a 90 m² apartment.
Everywhere else the price is deregulated and no government publishes a schedule. The indicative market ranges below come from consumer bodies, assessor price lists and comparison sites, so treat them as orientation rather than quotes:
| Market | Indicative cost, normal flat |
|---|---|
| Hungary | 22,000 to 45,000 HUF (roughly €60 to €125) |
| Poland | 350 to 650 PLN with a site visit (roughly €81 to €150) |
| Czechia | 3,000 to 5,000 CZK (roughly €125 to €205) |
| Slovakia | roughly €150 to €350, quoted per house rather than per flat |
| Italy | roughly €120 to €300, plus a small regional lodging fee |
| Austria | roughly €150 to €300 |
| Wallonia | roughly €150 to €250 |
| Netherlands | roughly €225 to €350 |
| Germany | see below, the question does not apply the same way |
| Flanders, Spain, France | no defensible figure found |
We are leaving three cells empty on purpose. Flanders states the market is free with no fixed cost, and we could not source a reliable range for Spain or France. A plausible-looking invented number would be worse than a blank.
Germany deserves its own paragraph. The certificate is issued for the whole building rather than the individual flat, with narrow exceptions for separately treated parts of a building and for some small buildings. The owners' association bears the cost, and the law gives an individual owner the right to inspect the association's records. Consumer advice centres go further and treat handing a selling owner a copy as the association's job, which is the practical position rather than an explicit statutory entitlement. So "what does it cost for my apartment" is the wrong question in Germany: a ten-unit block apportions to roughly €60 to €80 per owner, and many sellers pay nothing because the building already has one. The two variants typically cost roughly €50 to €250 (consumption-based, the upper end being a larger block) and, for the demand-based version, €300 to €500 for a house, with a block of flats priced as a base fee plus roughly €30 to €50 per unit. Consumer advice centres warn against the cheap online certificates sold around €70 without any inspection.
What happens if you skip it
Enormously variable, and this is where agency blogs are least reliable.
| Market | Penalty |
|---|---|
| Hungary | No fine in the energy certificate decree itself. The sale stays valid |
| Poland | A minor offence, 20 to 5,000 PLN, for not handing the certificate over at the deed. No penalty for the advertisement |
| Austria | Up to €1,450, separately for the advertising breach and for failure to hand it over |
| Slovakia | Private individual up to €2,000. Companies, sole traders and the agent face €500 to €3,000 |
| Netherlands | Several hundred euros for a private owner and roughly double for a company, per dwelling |
| France | Up to €3,000 for an individual, €15,000 for a company |
| Wallonia | €1,000 for no certificate, €500 for a non-compliant advert |
| Flanders | €500 to €5,000 for owners, €750 to €5,000 for professionals |
| Portugal | €250 to €3,740 for individuals, €2,500 to €44,890 for companies |
| Germany | Up to €10,000 |
| Czechia | Up to 200,000 CZK (roughly €8,280), and the same again separately for the agent |
| Spain | €300 to €6,000 depending on severity |
| Italy | €3,000 to €18,000 on a sale, €300 to €1,800 for a new lease with no certificate, €1,000 to €4,000 for one not attached to the contract |
| Brussels | €50 to €62,500, the widest range in Europe |
Three things worth knowing that most sources get wrong. Czechia's fine is 200,000 CZK, not the 100,000 that circulates widely, because the tiers were restructured and the older bands no longer exist. Slovakia has two separate tracks, and a private person selling their own flat faces the €2,000 ceiling rather than the business band everyone quotes. And in Poland the advertising duty carries no penalty under the energy performance act, because the article creating it is simply not among the acts that article 41 makes punishable. The fine attaches to failing to hand the certificate over at the notarial deed instead. The notary records that handover in the deed and, where nothing was handed over, formally cautions the seller about the fine, but does not refuse to complete the sale. A Polish seller still needs the certificate: a separate article requires one for any sale or letting, so the missing penalty is a gap in enforcement of the advert, not permission to skip the document.
Three national quirks that change what you should do
France bans letting the worst-rated homes, and the line keeps moving. A home below the threshold is not legally a decent dwelling, so it cannot be let at all. Class G has been barred since 1 January 2025, class F follows on 1 January 2028 and class E on 1 January 2034, with later dates overseas. The French rating is also the worse of two labels, energy and carbon, so a gas-heated flat can be dragged down by its carbon rating alone.
There is good news buried in this for French owners. A rule change in force on 1 January 2026 cut the factor for converting electricity into primary energy from 2.3 to 1.9, and the ministry's own estimate is that roughly 850,000 of 4.8 million of the worst-rated homes left those categories as a result. Existing certificates stay valid and owners can download an updated attestation for free, with no new survey. If you assumed you were stuck with an F, check before you spend anything on works.
Germany's certificate cannot be verified by a buyer. A registration number is compulsory, and the German Institute for Building Technology (Deutsches Institut für Bautechnik) issues those numbers, but it holds no public register and does not store the certificates themselves. A buyer cannot look up a certificate by its number, which is a real gap and the opposite of what some markets offer: the Netherlands, Brussels and Wallonia all run genuinely public registers, searchable by address or by the certificate number printed in the advert. Flanders used to, and has since moved its lookup behind a login, so a Flemish buyer now has to get the document from the owner.
Czechia defaults your listing to the worst rating if the agent never gets the certificate. Where an estate agent is marketing the property and is not given the certificate, the law requires them to advertise it in the worst class. A missing document does not quietly become no rating. It becomes the worst possible rating, published in your own listing. That particular duty binds the intermediary rather than a private seller advertising directly, but the private seller still needs the certificate for the sale itself.
What to actually do
Order the certificate the week you decide to sell, before you write a word of the listing. Check whether an existing one is still valid, because in Germany the building may already have one, and in Hungary or for a Spanish class G it may have expired sooner than you expect. Get the rating into the advertisement from the first day it is published, since almost every market now requires it and several fine the advertiser rather than the owner. Then build the listing while you wait for the assessor.

Frequently asked questions
Do I need an energy certificate to sell my house in Europe?
Yes, in every market Seeki.eu covers. An energy performance certificate is legally required before a sale in each one, and in almost all of them the rating must also appear in the property advertisement. A certified assessor has to inspect the property, so allow several days to a week. It is the step most likely to delay a listing.
How long is an energy performance certificate valid?
Ten years in most of Europe, with two exceptions. Hungary cut validity to five years in November 2023, and Spain gives a class G rating only five years while other classes get ten. Several markets also void a certificate early if works change the building's energy performance, and in Italy it expires if mandatory heating maintenance checks are missed.
How much does an energy certificate cost?
Between roughly €60 and €350 depending on the market, but almost nowhere is the price regulated. Only Portugal, which fixes a registration fee from €28.00 to €65.00 plus VAT by property size, and Brussels, which publishes an indicative €210 including VAT for a 90 m² flat, give an official figure. Everything else is market pricing that varies by property and assessor.
What happens if you sell without an energy certificate?
It depends enormously on where you are. Hungary's energy certificate decree sets no fine at all. Poland's energy performance act carries no penalty for omitting the rating from an advertisement, though it does fine you for not handing the certificate over at the deed. At the other end, Czechia goes to 200,000 CZK, Germany to €10,000, Portugal to €44,890 for a company and Brussels to €62,500. In Czechia the property must also be advertised in the worst class if no certificate is supplied.
Does the energy rating have to be in the property advertisement?
In almost every European market, yes, and the recast EU directive makes it a requirement everywhere. Some markets only require it where a certificate already exists, while Hungary and Austria require it unconditionally. France requires both the energy and the carbon class, and Belgian regions additionally require the certificate's unique code or the full address. This is the part that quietly costs private sellers money, because the rating has to be re-entered correctly on every portal you list with. The Seeki.eu app detects it from your photos where it is visible, keeps it on the listing, and carries it into each portal's export bundle under that portal's own field label, so it is entered once and cannot be forgotten on the third form.
Who pays for the energy certificate when selling an apartment?
The seller, in most markets. Germany is the significant exception: the certificate covers the whole building rather than the individual flat, and the owners' association bears the cost. An owner has a right to inspect the association's records, and consumer advice centres treat giving a selling owner a copy as the association's job. Many German sellers therefore pay nothing because their building already holds a valid certificate.
Before you list
The certificate is the long pole in a private sale, so it goes first, ahead of photography and ahead of pricing. Check what your market calls it, whether an existing one is still valid, and whether the rating has to appear in your advertisement from day one. Then use the waiting week productively: build the listing, price it against real local data, and be ready to publish the day the certificate lands.
Sources
The directive framing comes from the European Commission's energy directorate, which announced the infringement procedures on 15 July 2026. The advertising duty sits in the certificate provisions of Directive (EU) 2024/1275.
National rules were checked against consolidated statute wherever one is published. Czechia: Act No. 406/2000 Coll. on energy management in the version in force for 2026, for the ten-year validity, the advertising duty, the worst-class default that binds intermediaries and the 200,000 CZK ceiling. The lower figures still circulating, including on the State Energy Inspectorate's own pages, predate the restructured penalty tiers. Slovakia: Act No. 555/2005 Coll., for the ten-year ceiling, the performance indicator that must appear in an advert, and the split between the €2,000 individual ceiling and the €500 to €3,000 band for businesses and agents. Enforcement passed to the regulatory office ÚRSO in 2024. Poland: the consolidated energy performance act, Dz.U. 2024 poz. 101, where article 41 lists the punishable acts and the advertising article is absent from that list, and article 11 sets out the notary's role. The 20 to 5,000 PLN band is the general minor-offence range in the Code of Petty Offences. Hungary: Government Decree 176/2008 as consolidated, with Decree 200/2023, which cut validity to five years from 1 November 2023, deleted the "where one exists" carve-out from the advertising duty and introduced the sixty-day rule.
France: the Ministry for Ecological Transition on the energy performance diagnosis, Service-Public for the advertising duty and the €3,000 and €15,000 fines, the housing agency ANIL for the letting bans and their dates, and the order of 13 August 2025 for the conversion factor moving to 1.9 on 1 January 2026. The 850,000 figure is the ministry's own estimate. Spain: Royal Decree 390/2021 for validity, the class G exception and the advertising duty, with the €300 to €6,000 bands in Royal Legislative Decree 7/2015. Portugal: Portaria n.º 138-H/2021 for the registration fees, and Decree-Law 101-D/2020 for validity and penalties. Italy: Legislative Decree 192/2005, which sets the ten-year ceiling, the expiry tied to the heating maintenance checks and the penalty tiers.
Germany: the federal building energy act, renamed the building modernisation act in July 2026 and unchanged in its numbering, for the whole-building rule, the advertising duty, the compulsory registration number and the €10,000 tier covering certificate and advertising breaches. The German Institute for Building Technology states that its registry is not a public one. Owner access rights come from the flat-ownership act, and the consumer advice centres supply the pricing and the position on copies. Austria: the amendment to the Energy Certificate Presentation Act in force on 1 July 2026. Netherlands: the Enterprise Agency for validity and the advertising duty, the Cultural Heritage Agency for the monuments change, and EP-online as the public register. Belgium: the Flemish energy agency on validity, advertising and penalties, the Walloon public service on the certificate, its fixed fines and the certificate number that lets a buyer look the document up, and Brussels Environment, which publishes both the €50 to €62,500 penalty range and the indicative minimum prices, alongside the regional certificate lookup.
Costs are the weakest data here and are flagged as such above. Only the Portuguese registration fee and the Brussels indicative minimum come from an official schedule. Every other range is market observation drawn from assessor price lists and consumer bodies rather than an authority, and each varies by property, region and assessor. Two further figures could not be tied to an official source at this review and should be treated as approximate: the Dutch penalty amounts and the Walloon ten-year validity.
