Whether you watch TV or not doesn't matter. If you have equipment on the premises that is capable of receiving broadcast TV, basically anything with a Tuner in it, be it a TV, Video, PC Tuner, Settop box you are required to have a valid licence for that premises.
For example, you cam have an old Video-Recorder in a cupboard, not own any TV or monitor to view it on, but still be liable for the licence fee.
That isn't what the TV licencing website says...
