Not exactly, you can highlight over the CityFibre thing on the right of BIDB and it will show you all the live properties in your area.
I tend to check the map a lot, so in a way anyone can see 'recently activated properties' if they regularly check the map - screenshots help, I used to do this back in the day when I was waiting for my installation.
Although, if there's absolutely no permits being added and there's no work going on, it's unlikely that postcodes will just get added.
I feel like that'd be a pretty good feature for BIDB/TBB to implement though now that you say it.
I know, thats how I know the activated areas havent been spreading. The lines representing roadworks have stopped moving as well, when I driven around the streets with works, there is never anyone there but is unfilled holes, and a friend of mine his pavement has been dug up for 5 months.
The vast majority of the city still has planned cityfibre, so the issue isnt postcodes been added to planning, The city is Leicester, so you can start checking it, notice e.g. there is works in the Highfields area, those same streets the works first were started in October 2020.
The last activated areas in Beaumont Leys it took them almost 2 months to do a street with 30 houses on it.
Initially the roll out was far quicker.
