That was my original understandig when looking into it for them. However, the BT price lis quotes:
2) The FTTP on Demand Distance Based Charge is the variable connection charge which will apply to all FTTP on Demand orders in addition to the fixed connection charge. Openreach will calculate the relevant distance band for an Order using the radial distance from the relevant NGA aggregation node, calculated using the details recorded by Openreach.
Relevant being the key word - not nearest.
In their case the nearest node has a hill in the way and for BT to provide service from that node would require about 5km of ducting or poles as there is a total absence of them on that route.
