ADSB, not sure havnt heard a requirement, but re Transponder, if you have one fitted and its working then legally you MUST switch it on in the UK.
Personally I have a Mode S Transponder fed with GPS that squits out ADSB and one of those Pilot Aware jobs, I switch the lot on every flight not from fear of being technically illegal but because it would be daft not to
Im happy to be tracked in the air, grateful in fact
