You can do it both ways, you can take the existing tenant along with you OR you could go alone, but ONLY AFTER he closes his balance with Kahramaa.

Actually, the fact is, you can take over the connection ONLY AFTER he has closed his existing connection with the premises. So in order for HIM to do that, he has to take the present Electricity/Water reading and go to Kahrama office, take a Kahrama officer along with him and physically check the meters and shut it down. After that you can go on your OWN, and take over the connection, giving the necessary application (your rental agreement, QTD, etc.).

Instead of going through all this, the easier method is, both of you take the last reading, go together, he settles his final payment, you take over the connection at the same time. So you wouldn't need to take a Kahramaa officer to the sight for connection / disconnection.

Hope you got that clear.
