Freeview requires a TV license at £150.50/y, Netflix is £95.88/y for HD on 2 screens + download on 2 phones, half the price if you share it with someone.
You could ditch them all, but if you were going to pay for one service, id avoid TV its just not worth it imo, there’s very little good original programs.
Netflix for your TV shows and movies etc., plus YouTube for your “daytime” TV shows you could say and you’ve really got everything you need.
