I have just had this reply from David Wilson Homes.
“I am writing to update you on the current situation we have with the installation of Superfast Broadband on the Summersfield Development.
BT Openreach did report to us back in October that the service would be ready by the end of November 2014. However, Colin Brooks, the Sales & Customer Experience, NGA Development Solutions Manager, has today confirmed that they have a new route agreed for Power but this involves work on the Main Road. They are currently working with the Local Authority to agree dates as this requires traffic Lights to do the work.
We are continuing to chase BT Openreach regarding this and I will update you further once I have more information.”
