20 mins after posting this, Openreach Engineer came around and was really helpful.
The cupboard (cloakroom) is inside the house about 8 feet from the front door.
The engineer brought a reel of orange fibre, on a large metal wheel called a cobra, we found the grey BT box inside the cupboard and he started ramming the fibre down a hole that's just below the box.
He got 20-25M into the fibre going down then hit a block, that after some clever work, figured a way through, for another 5-8M, when he his another block that he couldn't get through.
Another engineer came to help out who had a device that was able to trace the route of my cable from the house to the manhole - We discovered that my current phone line runs right down the middle of our small road - So will need a civils team to come out and clear the block and look at the duct. The engineers said that, as the tarmac on the road is a special type(red stones in it), BT civils won't be able to do the job and it will need a specialist contractor, so may take a few more days.
I'm just waiting for a callback from the head of FTTP in Leyland, who will come out with a camera in the next few days to check the blocked duct and then move things on.
Have to say the Openreach guys were really friendly and good - Must be a tough job when things don't go as planned.
