SamKnows has just updated the details for my exchange for FTTC to 11/12/2011.
Does this mean the work in the exchange only?
Given the experience of the last year (ish) I'd fully expect your date (of December 2011) to move back April 2012. BT will probably decide this during August or early September.
I base this assumption on BT having many, many, dates pushed back (ours is currently mid-Sept, with our cabinet scheduled for 30th Sept - every three months our dates get pushed back three months - we were originally scheduled for the end of last December / early Jan 2011).
I wouldn't bother counting chickens until BT actually let you place an order.
There have even been reports on here of cabinets being installed and BT still pushing the enablement dates back.
Basically the whole thing is a mess with someone (either BT or the power companies) vastly under-estimating how long it takes to prepare each cabinet/exchange to go live.
