Thanks - I am keeping an eye on that thread. I'd have hoped my quotation would be at the lower end of the scale, and ironically I would have expected that running fibre from the node in existence for my neighbours who have FTTP by default (fed from the same manhole as where my copper DP resides!) would be easier than running fibre from the new cabinet through FTTPoD. I dread to think what timescales will be though, if it's taken 15 months to install one cabinet.
The latest from Openreach is that they expect the FTTC cabinet will be ready for service by 5 April 2019, and that compensation will be discussed after that date. I don't really want financial compensation, I would prefer that FTTP is installed and was originally offered to me. I think I will be combining a primary and a secondary FTTC connection in order to create an "Ultrafast" style service - well, that's what I have set up for, anyway.
