If the fly-tipping is on private land, you are responsible for its removal as the landowner. The council does not investigate or manage rubbish dumped on private property. However, if you have evidence from the scene about the fly-tipping that could identify the offender, you should report that evidence as it may assist in any potential investigation.
For more details on reporting or to learn about the legal responsibilities related to handling waste, you can read more on the fly-tipping page.
