Who should pay the utility bills for the period when the military live/lived in my house?

If you and the command of the military unit have concluded a rental contract (house or apartment), in this case, after the conclusion of the contract, payment for utility services and consumed energy carriers will be concluded by the military unit at the expense of the estimate of the Ministry of Defense under the terms of the concluded contract (paragraph 2, clause 2 of Section 9 of the Instructions).
