When a sale or letting is imminent – and the certificate is still missing

If you only think about the energy certificate now, you are not alone: in day-to-day work it often surfaces only when the calendar, prospective buyers or tenants, or the bank add pressure. Legally, § 80 GEG structures the answer: it requires that a certificate exists and sets out when it must be shown or handed over – not “sometime before moving day”. For a property sale or new letting there is therefore no single abstract deadline on the calendar, but there are clearly linked milestones (e.g. viewing, contract, listing once a certificate exists).

That is not legal advice for individual cases, but it makes next steps plannable: first check validity of any existing certificate (ten years under § 79(3) sentence 1 GEG, expiry date on the document § 85(1) no. 3 GEG), then certificate type and data availability, then appoint someone authorised under § 88 GEG.

When is an energy certificate mandatory? GEG at a glance

Sale and letting: what the law requires

If you intend to sell or let, lease or rent out a property, an energy certificate must be issued unless a valid certificate for the building already exists (§ 80(3) sentence 1 GEG). Typical cases include developed land, condominium units or creating or transferring a heritable building right on developed land.

Older residential buildings: For residential buildings with fewer than five dwellings where the building application was filed before 1 November 1977, a demand-based certificate applies (§ 80(3) sentence 2 GEG). That special rule does not apply if the building already met the 1977 thermal protection ordinance level at completion or was later upgraded to at least that level (sentence 3). In practice, talk to the issuer early so the correct certificate type is chosen.

Viewings, listings, contract: the critical moments

Your timeline depends heavily on whether anyone views the property – and whether you advertise it publicly.

On a sale, seller or estate agent must give the buyer the energy certificate or a copy at the latest at the viewing; a clearly visible notice or displaying the document during the viewing also satisfies the duty (§ 80(4) sentences 1–2 GEG). Without a viewing, it must be provided without undue delay, and on the prospective buyer’s request in any case (sentences 3–4).

After the purchase contract there is a further fixed point: without undue delay after the contract is concluded, the buyer must receive the certificate or a copy (§ 80(4) sentence 6 GEG).

For letting, leasing and similar, the presentation rules apply by analogy (§ 80(5) GEG with § 80(4) sentences 1–5). The explicit handover duty in § 80(4) sentence 6 refers by its wording to the purchase contract; for tenancies, arrange handover and documentation in a practical way – and in the contract if needed – so transparency and evidence work for both sides.

Listings: If you advertise on property portals and an energy certificate already exists at that time, the ad must include e.g. certificate type, final energy demand or consumption, main heating energy carriers, and for residential buildings year of construction and energy efficiency class (§ 87(1) GEG). If you want to list first before a certificate exists, you hit a classic bottleneck: § 87 presupposes in the statute that a certificate already exists at the time of the ad (§ 87(1) sentence 1); without a document you lack sound figures for a legally compliant listing.

Real-life scenarios

Selling a detached house – a notary appointment is booked

Example: Buyer found, notarisation in ten days. Under § 80 GEG the main legal pressure is often before the notary: at the latest at the viewing and after the purchase contract for handover. If the agent schedules viewings this weekend, the copy must be ready in fact, not “almost”.

The GEG does not state in general terms that a notary may not notarise without a certificate. In practice the document is still central for sales and finance: many buyers and lenders treat it as a standard item. Ordering too late risks slipped dates – and in the worst case a fine, not just inconvenience (§ 108 GEG).

New tenancy – first viewing in a few days

Example: Friday 5 p.m., first flat viewing, three portal enquiries. § 80(4) sentence 1 GEG is the guide: at the latest at the viewing the certificate (or a copy) must be there (§ 80(5) for letting). If it is missing, you need immediate action – including for searches like “create an energy certificate immediately”; legally what matters is actual data, not wishful timing.

A consumption-based certificate can sometimes be produced faster than a modelled demand-based one if reliable consumption data exist; whether that works for your building depends on the property, use and recent statements. A compact document list: Documents for the energy certificate.

An estate agent is involved – who is responsible for what?

If an estate agent organises viewings or publishes the listing, § 80(4)–(5) GEG and § 87 GEG matter in daily practice: the agent can share responsibility for timely presentation; for ads, whoever is responsible for publication and a certificate exists must ensure the mandatory details (§ 87(1) sentence 1).

Practical tip: In the agency agreement clarify who orders the certificate, by when the registration number is available and who archives copies for viewings and the owner.

What happens without a valid energy certificate?

• Presentation: § 108(1) no. 24 GEG covers failing to present in full, correctly or in time despite duties under § 80(4)–(5) GEG.
• Handover after purchase: No. 25 covers handover under § 80(4) sentence 6 GEG.
• Listings: No. 27 covers breaches of § 87 GEG.
• Fine ceiling: For these constellations (§ 108(1) nos. 21–28), fines of up to EUR 10,000 are possible (§ 108(2) sentence 1 no. 2 GEG). Higher caps in § 108 apply to other offences (§ 108(2) sentence 1 no. 1 etc.) – do not mix them up when citing the law.

Beyond that there is commercial risk: lost interest, renegotiated price or rent, delay until a valid certificate exists.

How fast can it really be? Traditional issue vs online

Consumption-based vs demand-based certificate (overview)

• Consumption-based certificate (§ 82 GEG): based on metered consumption – without sound data, no serious short-notice route.
• Demand-based certificate (§ 81 GEG): models demand – often less tied to the latest service-charge statement, sometimes more work to produce.

More detail: Demand-based certificates for residential buildings.

What drives the timeline (data, building type, certificate type)

Three factors almost always set the pace:

1. How complete are year of construction, envelope, plant data, and if needed three years of consumption data?
2. How complex is the asset (single-family vs multi-family, commercial parts, special uses)?
3. How quickly does the person authorised under § 88 GEG respond – and is an on-site visit required?

Anyone who wants an energy certificate quickly rarely chooses between “today” and “next week” alone; the choice is between adequate data and the right certificate type.

Online mainly means faster submission of data and often less post – not “without expertise” or “without checks”. Whether a provider offers fixed hour guarantees cannot be derived from the GEG or the BBSR portal; what matters is offer, data review and registration of the certificate number (§ 85(1) nos. 3 and 4 GEG; see also BBSR – rules on energy certificates).

Checklist: how to proceed now

1. Check your records: Is there already a certificate? It is usually valid ten years (§ 79(3) sentence 1 GEG); the expiry date must appear on the document (§ 85(1) no. 3 GEG). Expired = new certificate needed.
2. Gather documents: Documents for the energy certificate.
3. Clarify certificate type: demand-based vs consumption-based – if unsure, align briefly with a qualified person.
4. Commissioning: use a person or firm authorised under § 88 GEG; clarify the payment and data handover process early.
5. Viewing / listing: copy ready for the first viewing; listing with § 87 details only once a certificate exists (§ 87(1) GEG).
6. After the purchase contract: hand over without undue delay to the buyer (§ 80(4) sentence 6 GEG).

Conclusion and legal notice

When an energy certificate is needed at short notice, the situation can feel chaotic - but with the right sequence, it is manageable. The key is to organise documents early, clarify the right certificate type, and start issuance in good time. That way, your viewing, listing and contract phases are properly prepared, and you avoid unnecessary pressure close to key dates. Legally, three points remain central: presentation at the latest at the viewing and handover after the purchase contract (§ 80(4) GEG), mandatory listing details once a certificate exists (§ 87 GEG), and potential fines for breaches (§ 108 GEG).
