We also provide expert gas leak detection through our fully Gas Safe registered engineers. Whether it’s a suspected water leak causing unexplained pressure loss or a gas safety concern, we deliver fast, accurate results across every London borough.

Advanced Tracer Gas Leak Detection

Our leak detection service uses tracer gas technology:

Tracer gas detection using a safe hydrogen/nitrogen mix – highly effective for pinpointing even tiny leaks

We introduce the safe tracer gas into the pipework. It escapes through the smallest leaks and is detected from the surface using specialist sensors. This allows us to locate hidden leaks under floors, behind walls, in concrete, or buried pipes with great precision and minimal disruption.

Once the leak is found, we carry out a clean repair and provide a full report with photos for your records or insurance claims.
