The provider that divides water consumption (usually also the company that reads the meters) must follow the applicable legislation when dividing and calculating consumption per flat. The method of billing and dividing hot water consumption is set by the Rules on the allocation and billing of heating costs in residential and other buildings with several units, whose Article 10 also covers hot water. Here are the key points of Article 10 for easier understanding:
(1) At least 50% and at most 80% of heating costs are divided among the units by consumption shares (in this case water meters).
(3) At least 50% and at most 80% of the costs of preparing hot water are divided among the units by consumption shares (water meters).
(4) The remaining part of the costs of preparing hot water is divided among residential units by their share of the number of users, and among commercial units by their share of floor area.
(5) Notwithstanding paragraphs one to four of this Article, the costs of heating or preparing hot water may be divided differently among the units if the owners agree on the method with 100% consent and inform the allocation provider.
Put simply, the allocation provider, which is qualified to do so, sets the ratio between the part of consumption based on actual meter readings and a fixed part, which for hot water is charged by number of occupants. In practice, 70 or 80% of hot water consumption is usually charged by meters and 20 or 30% by number of occupants.
The problem is that on the monthly statements, managers cannot show hot water consumption based on meter readings and number of occupants simply in m³. Based on the rules above, the meter readings per flat and the number of occupants in each flat, the allocation provider calculates a percentage of consumption per flat and sends it to the manager. The manager or whoever prepares the monthly statement can therefore show hot water consumption to customers as a percentage.
Owners can check with the meter reading and allocation provider whether the division and consumption of their unit match actual consumption. To do this, contact the meter reading provider. Some providers offer online access to consumption data, others can send it by e-mail.
This all depends on the agreement with the meter reading provider and the price of the service, which the provider charges to customers through the manager. We work with 7 meter reading and allocation providers for water and heating. All our external providers now have almost 14 years of experience in this field and will be glad to help you if you need it.
