What capacity is there with BT to upgrade homes from FTTC to FTTP?

[norm]

In the future fiber to the premises will probably feature in a lot of homes.

What capacity is there with the current FTTC system to allow for this? Are the cabinets designed with idea of replacing all the copper to fiber at some point?

Do new builds in this country get fiber lines as standard already?

Here in Bath several new build developments are FTTP as standard.
