Keep the original details
Retain the letter, reference, meter information and any recorded readings. These help explain what prompted the concern.
Clarify the boundary
Identify the private supply route and any shared section if known. Responsibility should be confirmed rather than inferred from the location of visible water.
Ask about required evidence
Check what the water company needs after investigation or repair. Share those requirements before the report is prepared.
Explore the relevant service
General information for planning an investigation. The property, instruction and findings determine the appropriate work.
