The consumer has the right to non-payment of the cost of utility services, except for the supply of thermal energy, in case of non-use and in the absence of metering devices. This is possible if the period of temporary absence from the residential premises or other object of immovable property of the consumer and other persons is more than 30 calendar days. This must be documented in accordance with the terms of contracts for the provision of communal services (Clause 6, Part 1, Article 7 of the Law "On Housing and Communal Services".)

The fact of non-residence can be confirmed by a certificate issued on the basis of an act signed by at least three neighbors. If a person is registered, but does not live at the address of registration, it is advisable for him to confirm the fact of his stay at another address with an appropriate certificate.

This can be a document that confirms a person's location in another administrative-territorial unit in connection with work, treatment, training, long-term business trip, serving a sentence, etc.
