Looking for the best IPTV provider in the UK

Hello, I'm looking for the best IPTV service that only plays English-language channels, no irrelevant ones. I just want real channels like a set-top box. I don't care about Movied; in fact, I prefer a service without Movied because I already have the best movie apps. I just want a cheap service with smooth playback and no buffering or lag. (Of course, adult channels would be perfect.)
