UK pilots: how common is it to dump fuel over land while preparing to land? Above or below 10k feet? Is the CAA always informed (~62k total declarations per year)?

Context: We live below a flight path for aircraft landing at local airport and neighbours think planes are dumping fuel and it’s acting as a defoliant and leaving a residue on their house. Other explanations are more likely but would be good to get any informed views.
