Ask Wesslink to explain the condition of the equipment and physical fence, with the necessary corrections identified. Separate work needed to restore the existing arrangement from optional changes. If further assessment is required, agree what it will establish and how the findings will be used before buying parts or accepting a broad replacement proposal.
Where an electric fence installation replacement is appropriate, obtain the relevant owner or development approval and agree what happens to redundant equipment. At completion, ask for ordinary operating guidance and the final installation description. Keep records of components retained, repaired or replaced so a future occupier understands the current system rather than the abandoned arrangement they first saw.
