Looking at the Network over NW England at the moment, it does look fairly quiet. I can see EZY55AX and RYR73PC heading south, but not too much else. It could just be quiet at the moment.
Also, your house will block the aircraft in one direction - if there is anything between the aircraft and the antenna, the signal will be reduced or even blocked completely.
Switch the polar diagram on (yellow diamond button on toolbar above "Destination") and see how it builds up over time.
