I'd take anything they say with a pinch of salt. This is exactly what they've been telling me for almost three years now, each time using the same copy paste response that my area is in the "design" stage:
Currently, our build within this area is still within the design stages. We will work to complete and finalize our design. When this has been done, our dedicated team will build the spine of the network within your area, we aim to do this in the next few months.
When the spine has been built we can begin to offer a suggested go live date for your community as we are able to calculate the remaining timescale for the infrastructure build.
Yet there is a Netomnia manhole 5 metres from my front door and has been for 2 years now- I was even asked by the contractors to move my car. Asking Netomnia about this they seem to have absolutely no clue what I'm on about- even the CEO himself Jeremy told me in December that there's no records of anything being done on my street.
Last month on an adjacent street, they upgraded a single pole serving a total of 6 houses out of 20+ on that street, and this I've been tracking with some software I wrote - during this I found that in their internal systems it jumped straight from stage 4 (design) to stage 8 (ready for sale), so I really think they have no clue what's going on themselves.
Another example of this is my friend who now *finally* has a live YouFibre service, his property was "out of their build plans", but in summer 2023 with little to no warning and in the space of a few months, they built in his area and he received a call asking to place an order. I believe during this whole time their online postcode checker was stating that it was out of their build plans, then suddenly jumped to place order- not 100% sure as I didn't have my software written then.
