Water at the front of a property can cross a boundary, follow a slope or emerge some distance from its source. In Guildford, a useful first report describes where water is visible and how it behaves; it does not claim ownership of the leaking pipe before the network and private supply have been assessed.
Map the visible area
Take one photograph facing the property and another facing the road, keeping house boundaries, kerbs and meter covers in view where possible. Mark the first visible wet point, the direction of flow and the lowest collecting area. Do not lift covers in traffic, step into the road or probe soft ground.
Record whether the water continues in dry weather and whether it is clear, discoloured or carrying grit. Weather context matters: a wet patch after rain is not the same observation as one that grows through a dry period.
Understand why responsibility cannot be guessed
Thames Water describes the water main and communication pipe as company responsibility, while the supply pipe under private land is generally the homeowner’s responsibility. The surface boundary does not necessarily reveal the underground defect position, and water can travel along trenches or hard surfaces.
If the water is in a road or pavement, report it to the relevant water company with a precise location and photographs where the reporting service permits. If it appears within the property, keep the same evidence for the homeowner, landlord or leak specialist.
Treat ground changes seriously
New cracking, sinking, potholes or fast-flowing water require quicker reporting and a safe exclusion area. Keep people and vehicles away from undermined surfaces. Do not attempt to expose a buried pipe or insert tools into the ground, because other services may be present.
A professional assessment may combine supply checks, route information and leak-location methods. Your contribution is a dated surface record that shows development over time. That is far more useful than an unverified statement that the leak belongs to the council, water company or house.
Keep any reference number from the water company and note the time of each report. If the visible flow changes before attendance, add a new photograph from the same safe position. A clear chronology helps separate a developing event from several unrelated wet areas.
