Provide the earlier electric fence compliance certificate if available, along with the dates of known changes. If nobody can confirm when the fence last received attention, say so. An old document can help identify the installation, but the assessment still needs to consider what is present now and any subsequent damage, removals or alterations.
If a new electric fence installation or extensive alteration is being considered before occupation, arrange the site assessment alongside other reinstatement work. Explain planned gate, wall or electrical changes and obtain applicable owner or management approval. Electric fence fault finding may be needed where the condition or connection history is uncertain; avoid authorising replacement parts based only on an unanswered alarm.
