Hi,
We completed in June last year on our two apartments in Jardin 12 - not sure when the water meters were connected, but one payment was taken from our bank in October, the other in December. We still don't appear to have had the electricity meters connected. Last time I asked, I was told that none of the apartments in Jardins 11, 12 and 13 had been connected.
On that basis it could be several months before yours are connected, but in the meantime, just enjoy the free builder's supplies!!!
