Define the affected system
Describe the symptoms, areas served and any known shared connections. Provide available plans and the outcome of previous investigations. That helps establish what the new instruction needs to answer.
Agree operational constraints
Identify permitted testing windows, sensitive equipment and the person who can authorise isolation. Site induction, parking and access requirements should be settled before the visit rather than discovered on arrival.
Set the reporting requirement
Explain who needs the findings and whether a particular format is requested. Commercial work receives a separate quotation for the agreed scope. The residential package is not a tariff for larger networks or premises.
