Not everything that the landlord pays for the house may be passed on to the tenant. Think of major maintenance, such as mechanical installations, costs of the caretaker insofar as they are important for the landlord, and so on. If you are not sure whether everything that is charged is actually allowed, let us check your contract or service charge statement for you free of charge.
In addition, we want to indicate that the landlord may only charge for services that have been agreed in your contract!
