Underfloor heating leaks are particularly challenging because they're hidden beneath your floor covering, screed, or insulation. Early detection is crucial to prevent extensive water damage and avoid the massive expense of lifting entire floors. Understanding the warning signs helps you act quickly before small leaks become major problems.
Modern wet underfloor heating systems are generally reliable, but leaks can develop due to installation errors, corrosion, damage from other trades, or simply age. Scotland Leak Detection specialises in finding these elusive leaks without destroying your flooring.
System Pressure Dropping
If you're constantly topping up your UFH manifold pressure or the gauge drops regularly, you have water escaping somewhere in the underfloor pipework loops.
Cold Spots on Floor
Areas of floor that remain cold whilst the rest heats normally indicate a leak preventing proper water circulation through that heating loop.
Damp Patches Appearing
Moisture appearing on floors, especially around edges or through grout lines, suggests water escaping from heating pipes beneath.
Boiler Keeps Cutting Out
Modern boilers shut down when system pressure drops too low. If your boiler frequently displays low pressure errors, check your UFH system for leaks.
Uneven Heat Distribution
Rooms taking longer to heat or never reaching temperature could indicate reduced flow in specific UFH zones due to water loss.
Floor Damage Visible
Warped laminate, lifting tiles, stained carpets, or buckling wooden floors often result from prolonged underfloor water leaks requiring immediate attention.
Important: Underfloor heating leaks rarely improve on their own. The constant flow of warm water accelerates damage to floor structures, insulation, and can lead to mould growth. Early professional detection saves thousands compared to complete floor replacement.

How We Detect Underfloor Heating Leaks
Finding leaks in underfloor heating systems requires specialist expertise and advanced technology. Unlike traditional plumbing leaks, UFH pipes are embedded in screed or beneath insulation layers, making them impossible to access without significant disruption. Our non-invasive methods locate leaks precisely without lifting your entire floor.
We combine multiple detection technologies to ensure accurate results. Each method provides different data, and together they pinpoint your leak's location to within a few centimetres, allowing for targeted repair with minimal damage.
Tracer Gas Technology
Our primary method for UFH leaks uses a safe hydrogen-nitrogen gas mixture. We drain the affected loop, introduce the gas under pressure, and our sensitive detectors track where it escapes through the leak. This tracer gas method works through screed, insulation, and any floor covering, providing exact leak location without any dismantling.
Most Accurate for UFHThermal Imaging Analysis
Thermal imaging cameras reveal heat patterns in your floor, showing where hot water escapes from pipes. We can see temperature anomalies that indicate leaks, blocked loops, or air pockets. This completely non-invasive scan provides immediate visual evidence of problem areas.
Visual ConfirmationPressure Drop Testing
We isolate individual UFH loops at the manifold and conduct precise pressure tests. By monitoring pressure loss rates in each circuit, we identify which specific loop contains the leak, narrowing our search area significantly before deploying other detection methods.
Loop IdentificationAcoustic Detection
For larger leaks, our acoustic listening equipment detects the sound of water escaping under pressure. Highly sensitive microphones pick up frequencies inaudible to human ears, helping locate leaks in manifold connections and flow/return pipes.
Manifold SpecialistMoisture Mapping
Advanced moisture meters help us track water spread beneath floors, confirming leak locations and assessing damage extent. Essential for insurance documentation and determining whether structural drying is needed after repair.
Damage AssessmentEndoscopic Inspection
Where access allows, we use flexible camera equipment to visually inspect manifolds, connection points, and accessible pipework. This confirms leak sources and helps plan the most efficient repair strategy.
Visual VerificationOur multi-technology approach ensures we find your underfloor heating leak regardless of your floor construction—whether it's traditional sand/cement screed, modern flowing screed, or retrofit systems beneath timber floors.
Our Underfloor Heating Leak Detection Process
We follow a methodical process designed specifically for UFH systems. Our approach minimises disruption whilst ensuring we locate your leak accurately the first time, avoiding costly trial-and-error repairs.
Initial UFH System Analysis
We examine your manifold setup, review installation records if available, and discuss symptom history. Understanding your specific UFH configuration—zones, loop lengths, and floor construction—helps us plan the most effective detection strategy.
Manifold & Zone Testing
Starting at your UFH manifold, we check all connections, flow meters, and actuators. We then isolate each heating loop individually to identify which circuit contains the leak through systematic pressure testing.
Thermal Imaging Survey
With the system running, we scan your floors with thermal cameras to map heat distribution patterns. This reveals cold spots, water accumulation areas, and helps visualise your pipe layout beneath the floor.
Tracer Gas Detection
For precise location, we drain the affected loop and introduce tracer gas. Our detection equipment then pinpoints exactly where gas escapes through the leak, marking the spot for targeted repair—typically requiring access through just one or two tiles or a small section of flooring.
Leak Location Confirmed
We mark the leak location precisely and demonstrate our findings using our equipment displays. You'll see exactly where the problem is before any repair work begins, ensuring confidence in our diagnosis.
Repair Plan & Documentation
We provide a detailed report including leak location, photographs, technical readings, and repair recommendations. For insurance claims, our documentation meets all requirements. We can arrange repairs or work with your preferred contractor to resolve the issue permanently.

Why Choose Scotland Leak Detection for UFH Leaks
Common Underfloor Heating Issues We Solve
Underfloor heating systems face unique challenges that require specialist detection expertise. From installation defects to age-related failures, our team has successfully resolved every type of UFH leak across Scottish properties.
Understanding common failure points helps property owners recognise problems early and seek professional detection before extensive damage occurs.
Manifold Connection Leaks
Flow and return connections at the manifold frequently develop leaks due to thermal expansion, poor installation, or corrosion. We detect these without dismantling your entire manifold cabinet.
Screed Damage to Pipes
Pipes damaged during screed laying or by trades working after UFH installation. Common in new builds where other contractors accidentally pierce heating pipes.
Joint & Coupling Failures
Joints within floor loops (which shouldn't exist in proper installations) eventually fail. We locate these hidden connections precisely for repair or bypass.
Zone Valve Problems
Motorised zone valves and actuators leaking internally or at connection points. Our thermal imaging reveals these issues without dismantling control systems.
Expansion Joint Stress
Pipes crossing expansion joints in large floor areas suffer stress fractures. We identify these critical points for proper repair with flexible connections.
Frost Damage in Voids
Scottish winters cause frozen pipes in poorly insulated floor voids. We locate all damaged sections, not just obvious splits, preventing future failures.

The Critical Importance of Fast UFH Leak Detection
Underfloor heating leaks present unique challenges that demand specialist expertise. Unlike traditional plumbing leaks you can see and access, UFH leaks hide beneath layers of flooring, screed, and insulation. Every day you delay detection, warm water continues damaging your floor structure from within.
The financial implications of ignoring UFH leaks are severe. What starts as occasional pressure top-ups quickly escalates into structural damage, mould growth, and potentially complete floor replacement costing tens of thousands. In Scotland's variable climate, maintaining efficient heating isn't just about comfort—it's essential for property preservation and health.
Modern underfloor heating systems should operate maintenance-free for decades. When problems arise, they indicate specific failures that won't resolve themselves. Our advanced detection technology means you don't face the impossible choice between living with a leak or replacing your entire floor.
