Start with what you have noticed
Water escaping between a meter and a building can remain hidden below a driveway, garden or floor. A higher bill or supplier notification may be the first indication. Understanding the supply arrangement is as important as finding a wet spot.
Establish which part of the supply is affected
We consider the meter, accessible stop valves and known pipe route. Appropriate isolation checks can help separate a private supply issue from water use or leakage within the building. Acoustic investigation, tracer gas and other suitable methods can then focus the search. Shared supplies require agreement about access and interruption before testing.
Signs that can prompt an investigation
- Unexpected water meter movement
- A leak notification from your supplier
- Persistently wet ground in dry conditions
- Higher water consumption without an obvious reason
Planning the visit
Tell us if the supply is shared, crosses neighbouring land or runs beneath a finished drive. Any known valve positions and previous repairs are useful, but you do not have to locate them yourself.
