Openreach started out really well, came out and visited the site, pretty much said from the word go that the slimline boxes were really expensive and only got used on listed buildings so there was no way we were going to get them.
They agreed to relocate some of the CBTs and install extra ones (smaller units as they were serving less premises) so that cable runs could be kept to a minimum, and locate them in more discreet locations (tucked in next to downpipes). It seemed like a good compromise and we gave the go ahead, the extra ducting was installed ready for the cables but it's been 2 months now and we're still waiting, thought we'd sorted it but we're not there yet,
I'll keep you posted
