Two things about the Italian energy certificate that almost no overseas buyer expects.
It can expire early because somebody didn't service the boiler. And if it's missing from the deed, you pay half the fine, not the seller.
Here's how the Attestato di Prestazione Energetica actually works.
Italy uses ten bands, not seven: A4, A3, A2, A1, B, C, D, E, F, G. A4 is the best.
The trap is at the top. A1 is the weakest of the four A bands, roughly "as good as a current new build" rather than exceptional. Anyone seeing "class A" on an Italian listing will read it as outstanding. It isn't necessarily.
The second trap is what the class measures. Italian classes are set relative to a notional reference building of the same shape and size fitted with standard technology. So the class tells you how the property compares to what a building like it ought to achieve, not where it sits on an absolute scale. Three consequences:
The metric is non-renewable primary energy rather than running cost, which is why a house on bottled LPG in a hill village and a house on mains gas can land in different classes for reasons that have little to do with the bill you'll actually pay.
A ministerial decree that came into force on 3 June 2026 changed how the APE is calculated. Thermal bridges are now modelled explicitly, and gross rather than net surfaces are used.
It did not change the class scale, and existing certificates stay valid for their full ten years. But it does mean the same unimproved property can certify in a different band before and after that date. If you're comparing two similar properties with certificates either side of June 2026, you're not quite comparing like with like.
Italian law imposes four separate duties, and agents routinely collapse them into one:
It's triggered by a sale, a transfer for consideration, a donation, a new lease to a new tenant, a new build and a major renovation. It isn't triggered by a partition between co-owners, a comodato, a lease renewal or extension, or the sale of shares in a company that owns property.
Attachment isn't legally required at the preliminary contract. The disclosure and hand-over duties, though, bite before it.
Which matters because the compromesso is where your caparra goes down. A buyer who signs, pays the deposit and only then sees a poor class may be able to refuse the rogito and claim damages, but that's an argument you have to win rather than a protection you can rely on.
Ask for the APE before the deposit, not before the completion.
Two common misconceptions, because the wrong version of both is circulating in many English-language guides.
A missing APE no longer voids the sale. It did for about five months in 2013, and a notarial study from that period still gets quoted. The law changed in December 2013: nullity was replaced by an administrative fine. Your title is safe.
But the fine is split equally between buyer and seller. If you're told it's the seller's problem, that's wrong. And the Agenzia delle Entrate picks the omission up automatically when the deed is registered, then passes it to the region, so this isn't a matter of whether an inspector happens to look.
Unlike Spain, there's no buyer waiver. The obligation is public law and can't be contracted out of. The parties can agree who pays for the certificate; they can't agree away the liability.
Ten years, subject to two conditions, and the second one is unusual enough that it deserves your full attention.
First, a new APE is needed after works that change the class. Note the threshold is a change of class, not any works at all.
Second, and this has no equivalent anywhere else: the APE's validity is conditional on the heating system's mandatory efficiency checks actually being carried out. Miss one, and the certificate lapses automatically on 31 December of the year following the first missed inspection. No notice, no declaration, no process. It simply stops being valid.
The obligation applies to systems above 10 kW for heating or 12 kW for cooling, and compliance is evidenced by the libretto di impianto and its maintenance record.
Now the part that matters at the rogito. The notary has no duty to verify any of this. The notary checks that an APE exists and attaches it. Nobody checks whether the servicing was done.
So you can be handed, at completion, a certificate showing an expiry date five years out that died two years ago because the vendor skipped a boiler inspection.
This bites hardest on second homes and rural property, where boilers are used seasonally and servicing gets forgotten. Which is precisely the kind of property most international buyers in Italy are looking at.
Ask for the libretto di impianto with its maintenance record. Not just the APE.
No certificate is needed for:
Here's the thing to understand about that list. "No APE required" is a signal, not a saving. It usually means the building is uninhabitable, has no compliant heating system, or is registered as collabente, cadastral category F/2. Each of those has consequences for whether you can get a mortgage on it, whether you can live in it, and what it costs you in tax.
If a rural property you're viewing is exempt, ask why.
Start by ignoring the advice you'll find elsewhere. SIAPE is not a certificate lookup. It's ENEA's national statistical database, useful for aggregate figures on the Italian stock, useless for checking a specific certificate.
Verification is regional:
Regions also sample-check quality. Liguria audits 2% of certificates lodged each year, and where one fails the certificate is annulled and the technician is sanctioned, at no cost or penalty to the owner.
Expect €150 to €350 including VAT for a standard 80 to 120 m² apartment, and over €500 for a villa or a multi-unit building. Anything under €100 suggests the work was done without a site visit, which is a problem for both accuracy and validity.
Alto Adige is a different market entirely. A simplified APE starts around €250, but full CasaClima certification runs to roughly €1,800 plus an €800 agency fee, with air-tightness testing on top. Don't budget for Umbria and buy in Bolzano.
The certificate is the seller's legal obligation. The cost can be reallocated by agreement; the liability can't.
At the rogito, compliance is near-universal. The notary attaches the certificate, and the Agenzia delle Entrate detects an omission automatically when the deed is registered. This isn't policed by inspection, it's policed by the tax system. If an Italian seller is relaxed about not having an APE at completion, treat that as a warning about the whole transaction.
In advertising, non-compliance is normal and enforcement is sporadic. It happens by campaign rather than by continuous monitoring. In July 2024 the Guardia di Finanza inspected around 100 agencies in Jesolo and Cavallino Treporti and fined 29 of them a total of about €199,000 over 203 listings. A similar operation in Rovigo found about half the agencies inspected non-compliant, totalling around €100,000.
A hit rate of a third to a half tells you what baseline compliance looks like. Expect missing energy data on private listings and on rural property in particular.
67.6% of Italian residential transactions in 2025 were class F or G. Classes A and B together were 8.5%. In Naples, Palermo and Genoa, F and G run at roughly 90%; Rome, Bari and Florence are above 80%.
So expect the Italian property you're looking at to be an F or a G, and don't read that as a defect specific to that house. It's the market. The share has been falling slowly, from 73.1% in 2019, and prices are tilting modestly towards better-rated stock, but not fast.
Italian banks do offer better rates on efficient property, usually class A or B, with some extending to C and D.
The discount clusters around 0.20 to 0.45 percentage points. You'll see larger figures quoted on comparison sites; the measured evidence doesn't support them.
More usefully, Altroconsumo ran a mystery-shopping investigation across 70 branches in seven cities in mid-2026, posing as buyers of a €300,000 class-B home. What they found:
Their conclusion was that banks rarely disclosed the TAEG, the figure that captures fees and insurance, so it was often impossible to tell whether the green product actually beat the standard one.
So: insist on the TAEG and the standardised information sheet, and compare against the best non-green offer. Frequently they're from the same bank.
This information is most likely to save you money, or stop you wasting it.
The 2026 rates for renovation and energy works are 50% on a principal residence and 36% on anything else, capped at €96,000 per unit, falling again in 2027. Superbonus expired on 31 December 2025 and is effectively gone.
Then the catch. An Agenzia delle Entrate ruling of October 2025 confirmed that a non-resident cannot access the 50% rate, because it's tied to the property being the taxpayer's principal residence. A non-resident is confined to 36%.
Worse than that. These are deductions against Italian income tax, spread over ten annual instalments. If you have no Italian taxable income, you have nothing to deduct against, so the nominal rate is irrelevant. And the credit-transfer mechanisms that used to let people without Italian tax capacity monetise these have been closed off.
Most English-language material about buying in Italy gets this wrong, and buyers budget for a discount they can't claim.
The route that does work for non-residents is Conto Termico 3.0, in force since December 2025. It pays a cash grant from the GSE rather than a tax deduction, so it doesn't depend on having Italian income at all. For private individuals it covers heat pumps, hybrid and bivalent systems, biomass, solar thermal, heat-pump water heaters, district heating connections, and now solar PV with storage where it's paired with a heat pump. Rates generally run 40 to 65%, paid as a lump sum where the total is €15,000 or less, and you apply within 90 days of finishing the work.
If you're a non-resident planning renovation, build the plan around Conto Termico, not around the headline percentage.
Italy hasn't transposed the EU's recast buildings directive. It was left out of the 2025 European delegation law and the process only began in February 2026. The Commission opened infringement proceedings against all 27 member states on 15 July 2026, and Italy picked up a separate infringement in March 2026 over its missing national building renovation plan.
So the A4 to G scale remains the law. You may see claims that Italy moved to a seven-band A to G scale in May 2026. It didn't. That confuses the EU deadline with an Italian instrument that doesn't exist yet.
When transposition does happen, the scale will harmonise across the EU, with A meaning a zero-emission building and G redefined as the worst-performing 15% of national stock.
Do I need an APE to buy? The seller needs one. But you're jointly liable for the fine if it's missing from the deed, so it's your problem too.
The seller says they'll sort it before completion. Is that fine? Common, and usually fine, but ask for it before you pay the deposit rather than before you sign the deed. The class is information you want while you can still negotiate.
Is the APE really produced at completion every time? Close to it. The tax authority detects the omission automatically when the deed is registered, so notaries take it seriously.
The APE says it's valid until 2031. Can I rely on that? Not on its own. If the heating system's mandatory inspections were missed, it may already have lapsed. Ask for the libretto di impianto with its maintenance record.
Can I claim the 50% renovation bonus as a non-resident? No. Non-residents are limited to 36%, and if you have no Italian taxable income you can't use the deduction at all. Look at Conto Termico 3.0 instead, which pays cash.
The property is a ruin with no APE. Is that a problem? It's a signal. Exemption usually means uninhabitable, no compliant heating system, or registered as collabente, all of which affect mortgageability and tax. Ask why it's exempt.
Is it the same as the certificate I'm used to at home? No. Ten bands instead of seven, measured relative to a reference building rather than on an absolute scale, and capable of expiring early.
