Quick answer
A useful leak report sets out the property and inspection details, evidence found, tests performed, likely source, limitations and any repair completed. Ask your insurer whether it has a required format.
Clear details and observations
The report should identify the property, inspection date and the person or company carrying out the work. It should explain the reported problem and distinguish the customer's account from what the engineer observed.
A good report describes the affected rooms and visible signs such as staining, dampness or damaged finishes. Photographs should be labelled or clearly explained so the reader can understand their location and relevance.
Testing, findings and limitations
Where appropriate, the report can describe inspection methods such as moisture readings, pressure testing, acoustic checks or thermal imaging. It should state what was tested and what the results indicate in plain language.
A test does not always prove the exact cause or rule out every possible leak. The report should note areas that could not be accessed, conditions that affected the inspection and any further investigation recommended. Avoid treating a suspected cause as a confirmed fact.
Cause, work and next steps
- 1Record the likely source and explain the evidence supporting that view.
- 2List any isolation, opening-up or repair carried out, including the affected pipe or fitting where known.
- 3State whether a follow-up check was completed and its outcome; do not claim a repair is successful if it has not been tested.
- 4Include practical recommendations for reinstatement or further checks, while leaving insurance decisions to the insurer.
When to call a plumber
- Your insurer requests a written report on a leak.
- The source is hidden and needs specialist investigation.
- Damage has continued despite a visible repair.
- You need evidence distinguishing observation from an unconfirmed cause.
