Mr. Stein has a first hand answer for you above. Care to reply?
Hemel have had two articles on them in the national press in the Independent in Feb 2012 and in the Guardian on mar 2, 2013. This is for a team that was not a member of CC1 even until the beginning of this season. They have also had mentions on the BBC sport website and have had local articles re the re development of their Pennine way ground.
The Broncos, despite being a current and past SL club, have had very little press coverage. I can find an article in 2012 in the Mirror in regards to Gower joining them and a BBC website mention re their playing at the Stoop. they also have had two match reports in the Guardian this year, one the extremely positive fact that they managed to lose to wigan 64 to 6. good press that one.
This was a brief google search by me and there may be other reports for both teams so don't treat it as the gold standard on the subject.
