I would say your beacon was picked up by an I-Gate and so was seen in the UK. It wasn't 'heard' via RF but by the internet. That's normal.

How did you know that your beacon was "heard" by England? What were you looking at that told you that?
APRS.FI is a great site for looking at your APRS data. You can tell what stations heard your beacon as well was which stations relayed it to the iGate.
