We're hoping to do something similar, if we can get funding via the Gigabit scheme. There are only five of us though, and only two of the five have a need for higher speeds because they are now trying to work from home. In our case the fibre needs to run overhead, across the stream in the floor of the valley, and it's the cost and legal hassles associated with doing that which is the main issue right now. We can't easily put the fibre underground, as the only route would be along the lanes, plus there's now a prohibition on running services using small rural bridges. I ran into this latter problem when we had power put in, and with not being able to connect to mains water or drainage, we weren't allowed to run anything cross/under the bridge. Means we don't have mains water or drainage, and had to run the power cable overhead, which cost a lot at the time. I'm kicking myself for not having thought to add a fibre to the consents for the poles etc at the time, as it's this which is currently one of the reasons that Openreach are being a bit awkward.
