Additional costs 2024: This is how the energy certificate affects your rental costs!

Today, December 29, 2025, an interesting rental opportunity is taking shape in Hamburg. The newly offered apartment has a net rent of 1,350.00 euros, while the flat rate for additional costs is 300.00 euros, which also includes internet access. If you are interested, you can contact us directly via message. According to the information, unannounced visits are not permitted and broker requests will be rejected. This is underpinned by the regulations of Section 7 UWG, which prohibit unsolicited contact by brokers without consent. The “ohne-makler (OM)” portal is neither a provider nor an agent and was therefore able to publish the advertisements on several real estate portals.

But what else should potential tenants know? An important aspect is the energy certificate, which, according to nebenkosten-assistant.de has come into focus since the introduction of CO2 cost sharing in 2024. This certificate proves the energy requirements or energy consumption of a property and should be presented every time you rent a property. There are two types of certificates: the consumption certificate, based on the last three years of actual consumption, and the demand certificate, which calculates the theoretical energy requirements based on the building data. Special rules apply to buildings built after 1977 and have more than four residential units.

Energy certificate and additional costs

From January 2024, landlords will have to cover part of the CO2 costs, although the exact breakdown of the costs depends on the energy efficiency class of the building. For example, tenants pay 100% of the costs for classes A and B, while landlords only pay 5% for class H. This can have a significant impact on operating cost accounting. Potential tenants should be well informed: a missing energy certificate can result in fines of up to 15,000 euros, and the use of incorrect energy efficiency classes can also lead to legal problems.

But what about the costs for the energy certificate itself? According to mietrecht.com, these range between 50 and 100 euros for the consumption certificate and between 250 and 400 euros for the requirements certificate. However, it should be noted that the energy certificate can only be issued by certified bodies, such as architects or civil engineers - a measure that ensures that all information is correct and binding.

Regulations for owners and tenants

It is important for owners to know that the energy certificate is valid for ten years, but can be shortened in the event of renovations or conversions. The regional differences in costs and exhibition must also be taken into account. As the nebenkosten-assistant.de save, the energy certificate is not only a mandatory document, but also an important tool for tenants to be able to assess the energy efficiency of their new home.

In conclusion, it can be said that when deciding on a rental, it is not only the monthly costs that are crucial, but also the quality of the apartment, which is housed in an energy-efficient building. Anyone who takes the trouble to collect all the information has the chance to make a really good deal.
