Any downsides on BT Social Tariff?

Ectophile

TBH I thought Vodafone used BT, I did a check on Sky just to see what is installed around here, it said 67mb Part Fibre, which is their way of saying fibre to the cabinet, but would I be right to assume that any connection to flats is not going to be full fibre?   

Is it not the case that at best they could do full fibre to the ground floor energy cupboard and then run on existing copper to the different homes in the building.

"Part Fibre" will be FTTC.  There's a fibre from the exchange to a green Openreach cabinet somewhere, and copper phone line the rest of the way to your flat.

Unless your block of flats is so big that Openreach have installed their own cabinet in the basement, then it will be a cabinet beside a nearby road.

Once Openreach declare that an exchange is fibre only, then new customers can only be fibre all the way.  If you live in a flat, you have to get agreement from the landlord to install a new fibre into the flat.

In theory, the Openreach fibre box could be in a basement, but then you'd have to run an Ethernet cable to the flat, which is quite a bit thicker than a fibre.  And the Openreach box needs a socket for power.
