Energy certificate mandatory: How to secure the best offers!

In Cologne, the topic of energy certificates is currently more important than ever. A current real estate offer from the region shows the necessity and legal requirements for complete documentation of the energy values ​​of a building. An energy consumption certificate was created with a final energy consumption of 76 kWh/(m²*a), which is valid until September 1, 2035. The property, which was built in 1951, has an energy efficiency class of C and uses gas as its main energy source.

But why do buyers and tenants need such ID? Quite simply: an energy certificate is required by law when properties are sold or rented out. This is regulated by the Building Energy Act (GEG), which has replaced the old Energy Saving Ordinance (EnEV). Information from the energy certificate must be included in apartment advertisements so that potential buyers and tenants have clarity about the energy characteristics of the property before making their decision. More specifically, the energy certificate is necessary for every new building that is to be heated and also when selling or re-renting houses or apartments.

Important details about the energy certificate

Another aspect that should be taken into account: While tenants in existing tenancies are not entitled to view the energy certificate, owners must at least present it when changing users. There are exceptions to this obligation, for example for monuments or small buildings with a usable area of ​​up to 50 square meters. In the case of comprehensive renovations, a new energy certificate is also required, unless it only involves individual measures, such as replacing windows.

Anyone who decides to purchase a property should also consider having a consultation with a specialist after the energy certificate has been issued. The certificate not only provides information about the energy condition of a building, but also provides insights into heating systems and the year of construction, which can be crucial for making an informed purchase decision. Especially in times of rising energy prices, modernization through insulation or heating replacement could prove to be wise.

Legal Obligations and Penalties

But it's not just the buyers and tenants who have a duty, the landlords should also be well informed. You are not allowed to pass on the costs of the energy certificate to the tenants and must ensure that a valid certificate is available. If you fail to do this, you could face fines of between 5,000 and 10,000 euros! Another point is that real estate advertisements in which the energy certificate is available must contain certain information, such as the type of certificate, the year of construction and the energy rating.

Ultimately, responsibility for both the accuracy and completeness of the property information lies with those responsible for the real estate offers. The experts at are also aware of this Living happiness agree that all necessary documents for identity verification, such as identity cards or commercial register extracts, must be available. In addition, the disclaimer applies to inaccurate information, as customers must check the property information themselves. These requirements ensure that everything is in order and help you get a good deal.

Overall, this example shows how important it is to deal with the legal requirements in order to avoid any legal problems. An energy certificate is much more than just a piece of paper - it is a key to sustainable living and efficient energy management.
