Prepare the right starting point
Tell your landlord or managing agent about the signs, their timing and the affected rooms. Photographs and a short chronology can make an instruction more useful without needing your own diagnosis.
Agree authority and scope
Do not authorise work beyond your permission. A draft from this website is a personal record and does not notify your landlord or Leak Lab.
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.
