Can the landlord request the tenant to pay the chiller in the middle of the contract?

I live in Dubai Marina, and the landlord claimed that according to new Dubai Land regulations, the chiller now has to be paid by the person occupying the apartment.

Even though my contract says that the landlord should pay the chiller, they want to implement this mid-contract.

I understand that the terms upon renewal will be renegotiated, but on what grounds can they implement the change mid-contract?

Does a new DLD regulation precede a tenancy contract? Moreover, I am receiving a disconnection notice from the chiller company due to non-payment.

What can I do if this happens?

Please advise.
