My sub gen 3 is showing as connected to my Beam and 2 x Era 300...but no sound. I've unplugged, plug back in - no joy. Done a factory reset and added back in, twice, still no joy. I'm fresh out of ideas. Any further suggestions welcome...

As you already have done a factory reset of the sub for two times, I recommend the following:

If Beam is lan cabled first please make sure its wifi module is turned on anyway. If so go on…
1. remove the sub from home theater configuration and factory reset again. But then do not add it again to the ht setup but if possible to a single speaker or stereo setup room. That just to test if it works at all and puts out some bass sound. 
2. if that also doesn’t work, call Sonos Support to check your sub. 
3. if step 1 has worked, also remove the rearspeakers from ht setup, factory reset the Beam and stay the wifi module turned on though Beam might be lan cabled. 
4. set up the ht again starting with Beam and Sub.

 Is it just the Sub you don’t hear?

 Does your HT room on the app look like this screenshot?

Yes, just the sub I'm not hearing. But mine doesn't show the sub in the list, just my surrounds. But it has the option to remove sub which suggests its there. The sub was showing under my system, but not assigned to a room,  which I did and it said connected to my HT. But doesnt list it like yours. Very confusing...

 Yeah, that’s odd.  I have read that somewhere the sub should show as an unassigned device.  Does the Sub 3 show in your About Your System list ( gear - Manage - About Your System.  Scroll down )?  I think when the sub is not assigned the first line for the Sub in the About Your System list will be Sub|Sub.  Other wise it would read Sub|’Room Name
 

Maybe factory reset the sub and start over.
