Apologies if in the wrong section, but I have just bought a H7S box and dipping my toes into the satellite game!

Just moved into a new house and the previous occupants had some form of sky I believe, so plugged in the f plug from the box to the wall and tried to set up Freesat channels. I have gone through combinations of ABM and blind scans and signal finder but can't seem to get more than around 40 channels or so and none of the BBC, ITV or common channels.

Could it be that there is a Sky Q LNB on the dish and I need to get it changed or am I doing something hopelessly wrong? I have managed to get as good a photo of the LNB as possible and would appreciate any input.

Thanks in advance everyone!
