Umm, C33 appears to be used by Emley Moor!
Which transmitter do you get you Freeview from David?
You seem to be in a "good" location that can get signals from several (4) transmitters which are spread across most of the currently used UHF band (21-48) and that's in normal weather conditions.
Have you noticed any degradation whatsoever in Signal Strength but especially Quality on any of your normal reception? The reason I've asked is the possibil8ity of getting a free filter if you have noticed degradation. which if put in the correct place in your system might get rid of mobile interference.
The other thing I'd suggest is ensuring you are using double screened coax for your aerial and flyleads especially, to try and minimise interference getting into the system.
Are you using any amplification in your distribution system?
Maybe trial and error as regards choice of channel, I'd first try C49, C38, C39
Channels in use you may get signals from are 22, 23, 25, 26, 28 - 37, 40, 41, 43, 44, 46 - 48.
Other than that, try your Manual tuning on the TV to check what signals you actually are getting, obviously the direction and orientation of your aerial will reject a number of signals but others will be received off side lobes and the rear. Anything you find absolutely clear may be usable.
