I spent 9 months trying to get a G.network connection to a 12 flat block in Marylebone - I had to have two surveys, landlord permission etc. and waited weeks/months between each step. In the end we had an agreed route into the building but the landlord wanted £3K for wayleave and legal fees which the managing agents won't approve so in the end I went with a Three 5G solution which works very well and is about the same price as the G.network 150Mbps tier.
There are plenty of reviews on TrustPilot:
