Common Questions — Leak Detection in City of London

How do you find a hidden leak in City of London?

We use three methods in City of London: thermal imaging (detects temperature anomalies from moisture), acoustic listening (picks up water escaping pressurised pipes), and tracer gas (pinpoints the leak to within centimetres). We choose the method based on the suspected location.

Can you find a leak without breaking up my floor in City of London?

That is exactly the point of specialist leak detection. We locate the leak precisely using non-invasive equipment first. Only if a repair is needed do we open the floor — and we open the minimum area required.

My water bill has doubled in City of London but I can't see a leak. What's happening?

A hidden leak on the incoming supply main between your external stopcock and your internal stop valve is the most common cause of unexplained high bills in City of London. We can survey the supply main using acoustic detection without excavation.
