Prepare the right starting point
You do not need to identify the pipe before describing a problem. Explain what changed, which spaces are affected and what has already been checked. Keep access panels clear and highlight finishes that need care.
Agree authority and scope
The £1,700 package applies to the agreed residential instruction. Read the access and reinstatement boundaries before planning the work.
A clear record at the end
The Trace & Access report brings relevant checks, access and plumbing work into one record. Explain any reporting requirements before the visit, and retain the document with the repair details.
