All I can find is the following:
Exchange Name: Wellfield
Exchange Code: NEWLF
Fibre Phase: 11a 2013-2014
Fibre Information: FTTC Planned for 30th September 2015
BTOR WaW: [Enabled area]
BTOR WaW2: Your area is enabled for Superfast Fibre but your cabinet is not ready yet so you can't place an
BTOR WaW2: order today. It is in our plans to be upgraded and we update this info weekly, so please check
BTOR WaW2: back later.
Result Count: Test Skipped.
*** Tests Skipped ***
Please note that these speeds are using BT's DSL Checker and uses the lowest and highest values for that postcode and cabinet.
† Had at least 1 issue retrieving information from the BT DSL Checker.
So I say it could be around the end of September, the delay could be down to loads of things, blockages, planning permission, lack of engineers due to them working on BDUK work.
We are in the same sort of issue for our FTTP install where we only need the fibre blown in, all the relevant manifold hardware has already been installed, its been that way since Oct - Dec 2011.
So it all boils down to just waiting I guess.
