It is but it's in the large "up to Dec 2026" bucket. The exchange is Gainsborough and it's a long time since it was the capital of England...
Probably meaningless comparison, but mine is in the 2024 timeline but they've made a ton of progress. So it really depends if your street is the start or the end of the process.
My understanding is, the easier your street is to do, the sooner it will likely be done. Around here the areas with existing ducting or easy pole to pole runs were done months ago (though only became available to order this week), but mine was just done yesterday as there was no existing duct across the road.
There's also pressures of competition. Virgin and CityFibre also are rolling out round here, and it seems if they can use 90% Openreach ducting/poles, then they're not averse to putting in their own to fill the gaps if they can beat the competition.
There's been a direct correlation between how quick Openreach have been doing works and how much Virgin have, though obviously I can't be sure its because Virgin are following Openreach closely so know they can use their new ducts, or if they are outright trying to beat them to it.
