Thanks Ribble. What you say makes sense except that the Openreach site makes no acknowledgement of fibre ever coming to that cabinet. Where I used to live, just outside Yeovil the cabinet there has been showing upgrade to Fibre in six months time. By that I mean that it is always at least six months away from whenever you check on a rolling delay. There is no sign of Fibre activity there yet. I assume that one difference is that that one is supposed to be part of BT/Openreach roll out whilst my current cabinet is a BDUK offering. I guess I will just have to wait and see.
I brought the subject up now because I have had my BT line rental on an annual basis and it is due for renewal in a couple of weeks. If fibre were imminent I would rather not be committed to BT for another year but free to consider all options. If it is not coming in the next six months or so then I might as well renew.
Thanks to all who replied to this thread. If or when there is any more news I will post an update. Meanwhile patience is called for I guess.
