Make the instruction clear
If you rent your home, record the symptoms and tell your landlord or managing agent promptly. You can help by explaining the pattern, while the authorised person agrees the investigation and any access.
What helps before the appointment
Keep existing photographs and note changes after heating or water use. Tell the person arranging the visit if the engineer needs access through shared areas.
From investigation to an agreed repair
Suitable checks and specialist methods help establish the evidence. The proposed access is explained before the agreed plumbing work is performed. Appropriate testing and a written report help make the outcome understandable to the people coordinating the property.

Do not assume you are authorised to approve destructive access or commit the landlord to payment. The booking must identify the person instructing the work.
Coordinate the stages after repair
Restoring floor coverings, plaster, decoration and other finishes is separate from the plumbing package. Drying may also need specialist attention. Keep the report available for anyone arranging those follow-on stages.
