Mihajlo Becej - stock.adobe.comBilling for hot water in commercial spaces within mixed-use buildings requires adapted calculation methods. Flat-rate charges often lead to inequities. Solutions include special agreements, usage-based area allocation, or individual distribution keys.
Why is billing for hot water in commercial premises often problematic?
In mixed-use buildings, such as residential and commercial units, consumption patterns often vary considerably. For example, an office or a small supermarket requires very little hot water compared to several apartments in the same building. However, the German Heating Costs Ordinance (Heizkostenverordnung) does not take these differences into account when calculating basic costs. This leads to incorrect cost allocations and unfairness in the billing of hot water for commercial premises.
How can landlords fairly distribute hot water costs in commercial premises?
The following solutions are possible:
- Special agreement according to Section 10 Heating Costs Ordinance:
Hot water costs are distributed 100% according to consumption. This prevents small business users from being burdened with disproportionately high fixed costs. - Usage-based area calculation:
Only areas with actual hot water taps are included proportionally in the basic costs. This means that commercial spaces with minimal hot water consumption are not fully included. - Individual distribution key:
A formula converts hot water taps into permissible square meters. For example: 10 m² are allocated per "tap," which reduces the burden on commercial premises with few taps.
In cases of extreme consumption, for example in hairdressers or restaurants in mixed-use buildings, a User group separationLarge consumers are billed separately using submeters. The remaining users then pay regular basic and consumption charges.
Conclusion: Individual billing is crucial for fair cost distribution.
The standard regulations of the Heating Costs Ordinance are insufficient for billing purposes. Hot water in commercial premises This is often not possible. Landlords should therefore rely on special agreements, usage-based floor space calculations, or allocation keys to ensure fair costs. This is the only way to avoid unnecessary additional costs for small commercial tenants.

- If necessary, agree on a special arrangement in accordance with Section 10 of the Heating Costs Ordinance.
