Start With The System
Choose The Right Leak Investigation
Start with the pipework or system most closely connected to what you have noticed. If the source is uncertain, use the symptom guidance below or request a call back rather than assuming a particular leak type.
Supply pipework
Mains And Underground Supply-Pipe Leaks
For possible water loss on private supply pipework between the meter, boundary and property.
- A meter continues moving when water is off
- Unexplained usage or underground water loss
Heating circuits
Heating And Underfloor Heating Pressure Loss
For recurring pressure loss affecting radiators, concealed heating pipework, manifolds or underfloor loops.
- Boiler or sealed system pressure keeps falling
- Underfloor heating needs repeated topping up
Symptom Guidance
Not Sure Which Service You Need?
Symptoms can have more than one cause and do not confirm where water is escaping. Use the closest pathway to understand the next sensible route without treating the symptom as proof of a hidden leak.
High water bill or running meter
Review what a moving meter or unexplained usage can indicate before choosing a supply-pipe investigation.
Check water meter symptomsBoiler or heating pressure dropping
Pressure loss can have several causes and does not by itself confirm concealed pipework leakage.
Review heating pressure lossDamp, staining or moisture
Moisture may come from plumbing, rainwater, condensation or another source that needs separating.

Checks may need to distinguish pipework from seals, grout, enclosures and waste connections.

Occupied and multi-property buildings need an investigation planned around access and operational constraints.

Investigation Process
What Happens During A Leak Investigation?
The sequence is adapted to the property and evidence. No single technology is suitable for every suspected leak, and an investigation does not guarantee that a leak will be confirmed.
1
Initial Assessment
The symptoms, property construction, affected system and available evidence are reviewed.
2
Non-Destructive Investigation
Methods are selected for the suspected pipework and property rather than applied as a fixed package.
3
Leak Location Evidence
Test results are compared to narrow or identify the likely source; symptoms alone are not treated as proof.
4
Report And Recommendations
Findings and limitations are explained so repair planning, access or an insurance enquiry can follow.
Published Investigations
Evidence From Different Leak Investigations
These published examples show how symptoms, pipe location and investigation methods differ across internal, mains supply and heating-system work.

Methods Selected For The Evidence
Engineers choose methods after considering the symptoms, pipework and property construction. Several methods may be combined where each contributes useful evidence.
Thermal Imaging
Infrared patterns can help assess temperature differences associated with concealed water movement.
Tracer Gas
Trace gas can help narrow an escape point where the relevant pipework can be isolated and tested.
Acoustic Detection
Sensitive listening equipment can assess leak noise through pipework, floors or ground.
Moisture Mapping
Comparative moisture readings help interpret water spread and distinguish affected areas.

Leak Detection Services FAQs
Which leak detection service do I need?
The right service depends on the symptoms, system affected and whether insurance evidence is required. Contact us with the property details and we can advise the most suitable investigation.
Do you use non-destructive methods?
Yes. We use methods such as thermal imaging, tracer gas, acoustic detection and moisture mapping before access work is recommended.
Can you provide reports for insurance claims?
Yes. Written findings and photographic evidence can be provided for trace and access, escape of water and insurer or loss assessor requirements.
Do you work on commercial properties?
Yes. We investigate leaks in commercial buildings, offices, retail units, managed properties and facilities-managed sites.
What areas do your services cover?
We cover London, Surrey, Berkshire, Buckinghamshire, Oxfordshire, Hampshire and Sussex for residential, commercial and insurance-led leak detection surveys.
