When is the energy certificate mandatory in Luxembourg?

In Luxembourg the energy performance certificate must be presented when a building is sold or rented. It is also required for new builds and major renovations.

In practice, have the document ready before listing: buyers and notaries ask for it, and missing it delays completion.

The applicable rules are published on guichet.public.lu; we link the official source rather than interpret it.

What does it cost?

Market prices are typically €350 to €700 for an apartment and €600 to €1,200 for a house. The workload depends on how complete the building documents are.

Missing plans or heating details force the expert to survey and research more, which is the main cause of higher invoices.

Gather plans, past renovation invoices and details of windows, insulation and heating before the visit.

Validity and timing

The certificate is valid for ten years. After a major renovation a new assessment is worthwhile because the building's rating improves.

Expect one to three weeks between request and delivery, depending on availability and documents.

Do not leave it until just before the notary appointment.
