Will add a little factoid to this discussion.
OR have been assisting us with our CFP, and rang us up the other day asking if they could add some more properties to the plan etc (We would just need to get a couple more vouchers and it makes people happy, so i thought why not! - Quite a rural area too!)
We've been waiting for a cost to come back this week, but turns out Openreach had to send someone out especially to survey the area so they could price it up! (Quickest i;ve seen them move)
