Common Questions — Leak Detection in City of London

How does acoustic leak detection work in City of London properties?
We place acoustic sensors on accessible pipe fittings and use specialist software to calculate the precise location of a leak based on the sound it produces. This works through floors, concrete slabs and under tarmac.
My water bill has gone up but I can't see any leak — what should I do?
An unexplained increase in water use often indicates a slow leak on the supply pipe between the street connection and your internal stopcock. We can test for this without breaking any floors.
Will you need to dig up my floor?
Only if the leak is confirmed to be in a buried pipe section and there is no other access. In the majority of cases we can locate leaks non-invasively and make a targeted repair through a very small access point.
Do you provide reports for insurance claims?
Yes. Our leak detection reports are produced to insurance industry standards and include a site plan, photographic evidence, methodology used and repair recommendation. Most City of London insurers accept them.
