not sure abt the ntuc. but cdl provides 'free' electrical power. so u get to on ur aircon on the key collection.
u take the opportunity to test ur aircon.
some say to on the aircon for one whole day to test for leakage.
if ntuc is not providing this service. then activate on the same day as ur key collection. else, i see there's no need lor.
u might want to ask those already gotta their keys.
btw, the SP staffs came earlier on the activation day.
as for my renov, just startedthis week. things r moving slow.
no leh, i drop by one of the night, apparently still quite quiet. like not many has shifted. though there's initial rush for the key collection.
