I can hear the GAs on 26L if I have my office window open and they happen fairly regularly - as has been mentioned at EGKK it's probably more likely than not that the runway has not been cleared by a previous landing or departing aircraft than anything. I took a drive down to the end of 08R approach on Friday and was impressed by just how close they manage to get them during busy periods - a departing Air China A330 was only just rotating as an incoming TUI 757 was about to cross Lowfield Heath Road.
