Is there a way to encourage FTTH installation in my street/area?
As others have said, it's probably coming at some point, but if you want to be moved up the list, then it may be worth "lobbying" Openreach. In my experience, the best way to start is via the formal processes like Community Fibre Partnership. This at least gets you on their radar and may give you access to information about their plans which you might not otherwise get. An application also gets you a name/email address for future contact. As an example, it took me 4 years from first CFP contact, numerous update emails, contact at various levels of Openreach, requests put in by my ISP etc to finally get an FTTP connection. You may say that after 4 years it would have happened anyway, but there are still parts of my village where fibre infrastructure was started way before our work, and remains unfinished still. I'd like to think that by making a polite and reasonable nuisance of myself on behalf of my neighbours, we were moved up the list. It's worth exploring all avenues, but you have to be patient too!
