There is a company I read an article about , they wire up MDU (often local authority MDU) with their own internal FTTP infrastructure, (only the cabling inside the building) they then shop around looking for ‘partners’ to connect this internal infrastructure to the outside world via the network partners infrastructure, presumably they expect to collect a rental or part payment from the network or ISP or whoever for allowing access to their internal building network, this kind of arrangement is not common to the UK , but they may or may not be the company you quote as having provided the network inside your building.
It’s doubtful that this business model will ever work , certainly not with a network operator of the scale of Openreach , who , should the opportunity arise, will provide their own building cabling infrastructure not rent space in someone else’s infrastructure …for one thing , if Openreach used someone else’s internal network on this basis (ignoring the fee the building network operators would charge ) , if a fault develops, the ISP is on the hook for compensation to the consumer, Openreach is on the hook for compensation to the ISP , if this firm goes bust ,or has a policy of no compensation , OR are reliant on this other companies repair timescales
This isn’t an arrangement that OR would ever sign up to, so if this company is claiming Openreach are one of their customers, I’d want to see some sort of confirmation, it’s much more likely they phrase their communications to suggest an arrangement, something like ‘we partner with network operators like Openreach , rather than state they work with Openreach .
If it is this sort of arrangement in your MDU , it makes you no nearer to having access to BT as an ISP , they only use Openreach
