The responsible property contact should know which fence, if any, is affected by the proposal. A centre exhibition booking does not by itself describe electrical work at an outside boundary. For an independent property nearby, provide its actual address and installation details so the enquiry is directed to the correct premises.
For a permanent new electric fence installation or an alteration, obtain the applicable property and management approval and discuss it separately from the temporary display. Keep completed-work information and normal operating instructions with the responsible owner. Any temporary arrangement that still needs correction should remain clear in the handover until it has been addressed.
