Fast, Non-Invasive UFH Leak Detection
Signs of an Underfloor Heating Leak
Recognising the early warning signs of underfloor heating leak problems can prevent extensive property damage and costly repairs. Our specialists use advanced detection technology to locate the source of hidden leaks quickly and accurately.
📉 Boiler Pressure Dropping
If your boiler pressure keeps dropping and you need to top up the system regularly, this is a strong indicator of an underfloor heating leak requiring immediate investigation.
❄️ Cold Spots in Heated Floor
Unexplained cold patches in areas that should be warm indicate water escaping from the UFH pipework. Our thermal imaging leak detection identifies these anomalies precisely.
💧 Damp Patches or Wet Flooring
Persistent damp areas, warped flooring, or water seeping through floor joints signal concealed underfloor leaks. Early detection prevents structural damage to your property.
💷 Rising Energy Bills
A leaking underfloor heating system loses efficiency, causing your boiler to work harder. Unexpectedly high energy costs often indicate a hidden leak that needs professional attention.

How We Detect Underfloor Heating Leaks
Our underfloor leak detection specialists use industry-leading technology to find hidden leaks with precision. Every piece of equipment is specifically chosen to ensure rapid identification whilst protecting your flooring from unnecessary damage.
Thermal Imaging Cameras
Advanced infrared technology detects temperature variations in your floor caused by leaking hot water, creating a visual heat map to pinpoint the exact leak location.
Pressure Testing Equipment
We isolate and pressurise individual UFH circuits to confirm which zone has the leak and measure the rate of water loss for accurate diagnosis.
Tracer Gas Detection
Hydrogen gas tracing technology locates exact leak positions with millimetre precision — ideal for finding leaks under the floor without excavation.
Acoustic Listening Devices
Sensitive ground microphones detect the sound of escaping water through concrete screeds and floor finishes using professional acoustic leak detection.
Moisture Mapping
Digital moisture meters measure water content across floor areas to identify the extent of water damage and track leak spread patterns beneath the surface.
Endoscope Inspection
Flexible inspection cameras provide visual confirmation of pipe condition and leak points in accessible areas without dismantling your flooring.

What Our Customers Say
Common Underfloor Heating Leak Issues We Solve
Our underfloor heating leak detection services address a wide range of UFH problems for homeowners and businesses. Whatever your situation, we have the expertise to help.
🔧 Pipe Joint Failures
Leaks at pipe connections and manifold joints are common in UFH systems. We locate these precisely using pressure testing and thermal imaging without lifting your entire floor.
🏗️ Installation Damage
Pipes damaged during installation or subsequent building work. Our detection methods identify damage points for targeted repair rather than costly system replacement.
⚡ Screed Cracking
Movement in floor screeds can stress UFH pipes causing micro-fractures and leaks. We detect these hard-to-find leaks using tracer gas technology.
🌡️ System Age Deterioration
Older UFH systems may develop leaks due to material degradation. We assess system condition and locate leak points for efficient underfloor heating leak repair.
🏢 Commercial UFH Systems
Large-scale underfloor heating in offices, retail, and industrial premises. Our commercial leak detection minimises business disruption.
💧 Slab & Concrete Floor Leaks
UFH leaks in solid concrete floors require specialist detection. Learn more about finding water leaks under concrete floors.
