Reading the Data Ducting Infrastructure for New Homes - Guidance Note it states, on page 18, that in our circumstances the duct to be used to go from the point of Termination in the road to the terminal box on the outside of the house can be 30mm internal diameter minimum. The duct will travel under the front garden area and under the path around the house to the Terminal Box.

Has any one experience with this? What size ducting did you end up using?
Can I use black and wrap in green fibre optic tape?
I want to do this before they install the POT in the road.... ( soon)
