My confirmed order was submitted end of June. The survey said it required 34m of new duct and a new chamber.
OR first sent out their cabling people, who discovered upstream blocked ducts. It took a couple of months to fix and rope all of those. *Then* they started work on the new duct (mid-October). After digging a test hole, the contractor queried the permit[^1], left the hole with barriers around it for a couple of weeks, then fully reinstated it. A few weeks later they got a new permit and started all over again - they are working on it now.
I'm not expecting service until Jan-Feb at the earliest. But that's pretty good going compared to some.
[^1] The permit said "verge", and they weren't sure if this allowed them to work on carriageway or footway. However this bit of road doesn't have a footway
