I recall there was a voting system by BT circa 2002 to get your local exchange upgraded to "broadband" (i.e. not just 56k dialup) if it wasn't already.
It certainly wasn't a voting system. Rather, it was a decent enough system used to help gauge demand in a given area. (Unsurprisingly, there was a lot of demand for ADSL in university towns, and much less in retirement-town-by-the-sea).
Voting may be the wrong word but I think if you lobby your local area to submit their interest you'd have a good chance of getting it activated. There was a threshold and a tracker on the website.
