Thank you for all your replies!
Coincidentally enough we have had the contractors in to dig for the PCPs and FTTC cabs to be connected. They had been at all the PCPs except ours (I had assumed that this was due to the fact there had been no FTTC cab placed at our PCP)
However yesterday I noticed some roadworks up just past the PCP, and thought I'd wonder up today and have a look at what had been done. The contractors were back there today, and he signs around the roadworks showed that they were Infact working for Openreach...so I was nosy and went and asked them directly, they informed me they were about to put the new FTTC cab in this location further down the road from the PCP shortly.
No idea why all the others went in before but I'd take a guess at maybe collapsed or blocks ducts. It did look as though they were digging quite a way along the pavement in a narrow channel so presumably they had to clear the ducts before they could place the new FTTC cab. Either way I am more than happy with this news!
