Hi antsly
From what I see mate, you're probably not going to get it before the end of May .... that is my educated guess.
I'm not sure if you are aware of how FFTP builds tend to take shape in an Exchange area, assuming you don't I'll try and explain ?. This is just a guide, there are always grey area's and exceptions to the rule.
The Exchange area is divided up into PON's (areas) of 120THP (customers) maximum, per PON. This is done by our off-shore partners and is what we call a 'Ghost plan' .... ie: a blueprint. Once funding has been secured for that Exchange area, the survey tasks are created for each PON. A survey task is where an Openreach survey officer will physically 'walk the node' to see if tweaks can be made to the ghost plan.
The 'order of service' for these physical surveys, will usually take the form of working from the Exchange outwards following the spine cable (this is the larger fibre cable that individual PON's will connect to). There could be any number of spine cables per Exchange.
Once the survey results are returned, it then takes approx another 10 weeks to perform the other stuff, (planning, civils noticing, civils work, cabling, splicing, test and commission). Even after that, there is a dwell time before the PON goes CRFS (customer ready for service). As mooted earlier, this is merely a guide and times can and do alter depending on various circumstances. Every PON is bespoke.
Now armed with that info, I can see that a large number of PON's in the local area have already had their physical surveys completed and would imagine are at various stages of the other stuff I mentioned above.
There are a chunk of PON's that haven't have their surveys done yet, and that post-code you supplied me is indeed in one of those PON's. It looks to me by the way these remaining PON's lie, that they are potentially on the same spine cable ??.
So .... in a nutshell .... it looks like your PON's survey is imminent and the 'circa 10-week+ process' can begin.
HTH.
