Specialist UFH Surveys
Focused investigation for hidden underfloor heating pipework.
Underfloor Heating Leak Detection
Underfloor Heating Leak Detection
Professional investigation of suspected underfloor-heating leaks using methods selected for the circuit, property and available evidence.
We investigate concealed UFH pipework and damp floor symptoms using specialist leak detection equipment across London and Southern England. If repeated pressure loss is the main concern, understand why an underfloor-heating system may lose pressure.

What It Means
What Is An Underfloor Heating Leak?
Underfloor heating systems are usually pressurised circuits with pipework hidden beneath screed, tiles, timber or other floor finishes. When a pipe or connection leaks, the symptoms may appear away from the actual fault.
Leaks can cause pressure loss, heat loss, uneven floor temperatures and damp flooring. Because the pipework is concealed, the leak location can be difficult to confirm without specialist equipment.
Methods such as thermal imaging, tracer gas and moisture investigation may be selected where suitable to narrow the likely leak position before floor removal is considered.
Symptoms
Common Signs Of A UFH Leak
Boiler losing pressure
Repeated pressure loss can indicate a leak in the heating circuit or concealed UFH pipework.
Cold areas in floor
Unexpected cold patches may show where heating flow is restricted or pipework performance has changed.
Uneven heating
Rooms or floor zones heating differently can point to system imbalance, air, restrictions or leakage.
Damp flooring
Moisture beneath floor finishes should be mapped before lifting tiles, timber or screed unnecessarily.
Rising water usage
Unexpected usage may indicate a hidden supply or heating-related leak that needs diagnostic testing.
Repeated system top-ups
Frequent refilling can mask an active leak and should be investigated before further damage develops.
Process
How We Locate UFH Leaks
01
Initial Assessment
We review the heating system, pressure history, floor construction and affected rooms.
02
Thermal Imaging Survey
Thermal patterns are checked to identify abnormal heat loss and likely pipe routes.
03
Tracer Gas Investigation
Tracer gas can be introduced where appropriate to help locate concealed UFH leaks.
04
Findings Correlated
Results are compared to identify the likely source area and whether targeted access may be appropriate.
Why It Matters
Why Specialist Detection Matters
Reduce unnecessary floor removal
Structured diagnostic process
Evidence correlated across methods

Detection Methods Used For UFH Leaks
Supporting Methods
Additional Investigation Techniques
Endoscopic Camera Inspection
Small inspection cameras are used to visually check concealed voids, pipe routes and difficult-to-access areas before opening up.
Dye Testing
Coloured test dye can help confirm water paths, waste leaks, bathroom leaks and suspected escape routes.
Pressure Testing
Controlled pressure testing helps identify whether sealed pipework or heating circuits are losing pressure.

FAQs
Underfloor Heating Leak Detection FAQs
Can underfloor heating leaks cause boiler pressure loss?
Yes. A leak in an underfloor heating circuit can cause repeated boiler pressure loss or regular system top-ups, especially when the pipework is concealed below the floor.
Can tracer gas locate an underfloor heating leak?
Tracer gas can be used where the system and access points allow it. The gas helps indicate likely leak positions without lifting large areas of flooring first.
How does thermal imaging help with UFH leak detection?
Thermal imaging can show heat patterns, pipe routes and abnormal temperature changes across floor areas. It is used alongside other tests rather than as a single standalone proof.
Will the floor need to be removed?
The investigation starts with non-destructive methods to avoid unnecessary floor removal. Access is only recommended once evidence points to a likely leak location.
Can the findings support an insurance claim?
Yes. Written findings and photographs can support trace and access or escape of water claim requirements. Your insurer decides what is covered under the policy.
