This is an ethernet connection...
It might be worth trying to install a dhcp service on your PC and disable the one on the SH2 (just whilst testing). If the Bridge cannot successfully be configured using the PC dhcp server that would suggest the BT Hub is not the problem but the Tado bridge has an issue.
I guess the other thing would be:
You've not Set up the TADO in TBR mode (Thread Boarder Router), as you'd need IPv6 for this to work, which I don't think the SH2 does!

Yeah, of course it does.
