I *think* it has something to do with where these buses run.
U* buses mostly run around the Uxbridge area
H* buses mostly cover Harrow (except H1, H2 & H3, which go round
Hampstead Garden Suburb)
E* buses have an Ealing connection
PR* run around Park Royal

I don't know if Wood Green or Walthamstow gave their W to the W* buses
though.
A* buses are airport buses.

And T for associated with Croydon Tramlink I believe (eg T33)
