Who will pay the electricity bill after the outsourcing of hospital property?

This can't be elaborated, it depends on the property service contract.

However, in general, the payment of utilities does not belong to general property services, so it is generally paid by the owners themselves.

If the landlord means that the property has fully contracted the expenditure and use of utilities (including public parts), there are usually independent clauses in the property contract, which can be handled according to the contract. If it is omitted, it means that there is a big problem with this contract. It is recommended to find a professional to re-examine and re-sign the contract through negotiation.
