Looks like 30 channels on the surface (but likely to have at least 1 virtual/secondary layer) - 18 on the left and another 12 on the right.

My guess is 6 Outside Sources, 4 telephone lines, a couple of ISDN/VOIP lines, and 6 microphones on the left console. And on the right we can see the right-most faders are open at unity gain, which would imply they're output faders - so I suspect one for mic group, one for replay group, one for OS group, one for record out, and maybe one for studio out (though I hate this practice of including faders for outputs, especially your main out). That leaves about 6 for the playout system - probably 4 main channels and 2 cart/sound effect type channels.

Presumably the studios and kit have been standardised, so that they can be used by another programme or station in future if needed. Certainly having the station logo on a screen instead of a physical logo on the wall makes it easier to change, as well as ensuring it's in shot of any cameras if a section is recorded on camera for use online/elsewhere. Similarly the orange lighting that presumably signifies Radio 2 feels like it could be fairly easily changed if needed, as in that background you can see green lighting from another radio studio.
