I've been delayed 18 months overall. My exchange was one of the initial 66 exchanges announced for FTTC way back in 2009. Work was due to be completed in March of 2010 on Northolt and Greenford.... Greenford became enabled in July 0f 2010, but Northolt got deferred by 6 months. Then, like you, we were subject to delay after delay. December 2010, March, June, July, August, September, December, September again and now December 31st.
The only upside is that my exchange went live last month, and there are active cabinets a few hundred meters away. My cabinet has been in since May, and is humming away, but still isn't accepting orders according to BT. I don't know what they're up to, but I have my fingers crossed that I'll be live before December.
Hopefully they'll get their skates on and we'll all be active before December
