Excuse the pun and, urm, backseat driving. This is a pointed question to the British Unitarians out there.
Why are there no Unitarian churches in Milton Keynes, a postwar "new town" with more than 200,000 residents? Not even one. And, given the usual caveats about growth, it's set to double in population in the next twenty years, in part by growing the direction of the legally distinct but adjacent town of Newport Pagnell.
Now, except to change trains, I've never been in Milton Keynes, and all I know of Newport Pagnell is that (1) it's next to the M1, (2) it has an offramp service center/road services/rest stop and (3) it's mentioned in a Smiths song. But it's 13 miles from the church in Northampton, and that's the nearest one.
Is it really so strange for such a large residential area be targeted for a new church?
