Start with what you have noticed
With pipework concealed in a floor, an underfloor heating leak is difficult to judge by appearance alone. A cool patch may be a flow or control issue, while a leak can show up elsewhere. We investigate wet underfloor heating with attention to the manifold, loops and floor construction.
Use the system layout to focus the search
The manifold and isolation arrangements help explain how the floor loops are connected. Where practical, checks can narrow the investigation to an affected circuit. Thermal imaging and suitable tracer or pressure testing may help assess the route and likely source. Findings are considered together before access is discussed.
Signs that can prompt an investigation
- Pressure loss in a wet heating system
- Moisture emerging around a heated floor
- Water loss after work near heating pipes
- An isolated loop suspected of leaking
Planning the visit
Keep the manifold accessible if you know its position. Tell us about floor finishes and any installation plans. We will advise whether the system should be running before the appointment.

What does the £1,350 price include?
For an agreed residential job, £1,350 covers investigation, specialist detection, tracing, necessary access or excavation, the plumbing repair, parts, materials, post-repair testing and a Trace & Access report. The plumbing repair has a 12-month workmanship warranty. The total includes any applicable tax. Decorative and remedial reinstatement is excluded.
Do I need to identify the leak before enquiring?
No. Describe the actual symptoms, the full postcode and any earlier findings. The investigation establishes which system and methods are relevant; you do not need to open floors or choose detection equipment.
