Can't find that hidden leak? Our specialist engineers use advanced acoustic, thermal imaging and non-invasive technology to locate underground, underfloor and concealed pipe leaks — accurately and with minimal disruption to your property.
Why Leak Detection Matters
A water leak doesn't always announce itself. In many homes and commercial properties across Chelmsford, Springfield and Great Baddow, hidden leaks quietly cause damage for months before any visible sign appears — saturating walls, undermining foundations and sending water bills climbing without explanation.
Professional leak detection uses specialist equipment to find the exact source of a leak without guesswork. Rather than opening up entire walls or excavating whole driveways, our engineers identify the precise location — saving you from unnecessary damage, cost and disruption.
Early detection isn't just convenient; it's genuinely cost-saving. A slow mains water leak, a failing underfloor heating pipe or a concealed bathroom supply line — all can lead to thousands of pounds in repair costs if ignored. Catching these issues early keeps repair bills to a minimum.
Did you know? Even a pinhole leak can waste over 7,000 litres of water per year — adding significantly to your bills and potentially causing extensive structural damp in your Essex home or business.
What to Expect
At Anglian PHE, we bring the right tools and the right expertise to every job. Our leak detection specialists serving Chelmsford, Writtle, Broomfield and surrounding Essex areas have experience across all property types — from Victorian terraces with aging pipework to modern new-builds with underfloor heating systems.
We always attempt to locate leaks non-invasively first. Our engineers carry acoustic correlators, thermal imaging cameras, tracer gas equipment and moisture detection meters to every job, meaning we can identify the vast majority of leaks without breaking a single tile or opening a single wall.
Once the leak is found, we provide a clear report and advise on the most appropriate repair. We can carry out the repair work ourselves or work alongside your existing contractor — whichever suits you best.
Our Leak Detection Services
From underground water mains to underfloor heating systems, we have the technology and experience to find every type of hidden leak across Chelmsford and Essex.
Underground pipe leaks are among the most disruptive and costly to locate without the right equipment. Our engineers use ground microphones, acoustic correlation and tracer gas techniques to identify underground water leaks beneath driveways, gardens and roads across Chelmsford and surrounding Essex villages — without unnecessary excavation.
External water leaks — whether beneath a garden, driveway or path — can be deceptively difficult to locate by eye. We use specialist non-invasive technology to trace outdoor pipe leaks in Chelmsford, Galleywood, South Woodham Ferrers and across Essex, preventing unnecessary digging and identifying the precise fault location first time.
Leaks within underfloor heating systems are notoriously tricky to find without specialist thermal imaging technology. Our engineers map the heat distribution across your floor to identify exactly where a heating pipe is failing — without lifting tiles or damaging your flooring unless absolutely necessary.
Air pressure losses in commercial and industrial systems waste significant energy and money. Our compressed air leak detection service covers commercial premises across Chelmsford and Essex, using ultrasonic detection equipment to identify and quantify air leaks within pressurised pipework and systems.
Every hour a hidden leak goes undetected, the damage worsens. Call our Chelmsford leak detection specialists today for a fast, honest assessment.
Our Technology
Our first priority is always to locate the leak without causing any unnecessary disruption to your property. We carry a full suite of specialist leak detection equipment to every job in Chelmsford, Broomfield, Writtle and across Essex.
Infrared thermal cameras detect temperature variations in walls, floors and ceilings caused by leaking water — making concealed leaks visible without opening any surfaces.
Electronic acoustic correlators and ground microphones detect the sound signature of escaping water, pinpointing underground and concealed leaks to within centimetres.
A safe, inert hydrogen/nitrogen tracer gas is introduced to the pipe. A sensor then traces the gas to its point of escape — ideal for complex underground or heavily concealed systems.
Digital moisture detection equipment measures dampness levels within walls, floors and ceilings to identify areas affected by water ingress or concealed leaks.
Hydraulic pressure testing isolates individual sections of pipework to confirm whether a leak is present, its approximate location and the condition of the wider system.
Push-rod and pan-and-tilt CCTV cameras are used to visually inspect the inside of pipes, identifying cracks, joint failures, corrosion and blockages contributing to leaks.

Warning Signs
Hidden leaks rarely announce themselves clearly. If you notice any of the following warning signs in your Chelmsford, Braintree or South Woodham Ferrers property, contact our leak detection specialists promptly.
Moisture on walls, floors or ceilings with no obvious source often indicates a concealed pipe leak nearby.
A sudden or gradual drop in water pressure can point to a break or leak in your underground or internal supply pipework.
If your water usage seems unchanged but bills keep increasing, a hidden leak in your supply pipe is a likely culprit.
Persistent mould — particularly in areas away from bathrooms — can indicate long-term moisture from a concealed leak.
Unexpectedly warm floor areas can indicate a leak in an underfloor heating pipe circulating hot water beneath the surface.
Hearing the sound of running or dripping water when all taps are off is a strong indicator that water is escaping somewhere in your system.
Yellow or brown staining on plasterwork often indicates water leaking from a concealed pipe above or behind the affected surface.
An area of garden that remains unusually green or waterlogged may be receiving a constant supply of water from a leaking underground pipe below.

Frequently Asked Questions
Got a question about our leak detection services in Chelmsford or Essex? We've answered the most common questions below.
We use acoustic listening devices, ground microphones and thermal imaging cameras to trace underground pipe leaks without excavation. By measuring sound frequencies and pressure differentials, our engineers can pinpoint the exact location of a leak beneath driveways, gardens and roads — often to within centimetres. In more complex cases, tracer gas is introduced to the system to help locate the escape point precisely.
Yes. Our non-invasive leak detection methods — including acoustic correlation, thermal imaging and tracer gas — allow us to locate hidden pipe leaks beneath floors, walls and ground surfaces without any unnecessary excavation or damage to your property. In the vast majority of cases, we can identify the leak location before any physical work is needed, allowing repair work to be focused and minimal.
Non-invasive leak detection uses specialist equipment such as thermal imaging cameras, acoustic listening devices, moisture meters and gas tracing to locate leaks without breaking through walls, floors or ground. It protects your property from unnecessary disruption while still accurately finding the source of the problem. This approach is particularly important for properties with underfloor heating, period features or expensive flooring across Chelmsford and Essex.
Leak detection costs vary depending on the type of leak, its location and the detection methods required. Simple internal moisture surveys will cost less than a complex underground acoustic correlation survey. We always provide transparent, no-obligation quotes before any work begins and will never carry out additional work without your approval. Call us on 07825 348536 for an honest assessment of your situation and a clear cost indication.
Yes — underfloor heating leaks are one of our specialist areas. We use thermal imaging cameras to map heat distribution across your floor and identify exactly where a pipe is losing pressure or leaking. This allows us to target any repair work with precision, avoiding wholesale floor removal. We carry out underfloor heating leak detection across Chelmsford, Witham, Braintree and throughout Essex.
Our engineers use a combination of acoustic correlators, ground-penetrating microphones, thermal imaging cameras, tracer gas equipment, digital moisture meters, pressure testing rigs and CCTV pipe inspection cameras. The specific combination of equipment used on your job will depend on the suspected leak location, property type and access conditions. We invest in the latest technology to ensure accurate results with minimum disruption.
We aim to respond to emergency leak detection calls in Chelmsford and across Essex as quickly as possible. For urgent situations — such as a suspected burst underground pipe, active internal water leak or significant water pressure drop — call us directly on 07825 348536 and we will do our best to get an engineer to you at the earliest opportunity.
Yes. As well as locating leaks, our engineers can carry out pipe repairs — including water mains repairs, underground pipe repairs, internal plumbing fixes and central heating system repairs. We provide a complete leak detection and repair service across Chelmsford and Essex, or we are happy to work alongside your existing contractor if you prefer. See our pipe repair page for more information.
Absolutely. Even a slow hidden leak can waste thousands of litres of water per year, significantly increasing your bills. A concealed pipe leak that goes undetected for months can also lead to structural damp, mould growth and major repair costs on top of the wasted water charges. Early professional detection is always the most cost-effective approach — and it's one of the most common reasons homeowners and businesses across Chelmsford contact us.
Underground water leaks are commonly caused by pipe corrosion, ground movement, frost damage, tree root intrusion, high water pressure, poor original installation or simply the age of the pipework. Older properties across Essex and Chelmsford — particularly those with original lead, iron or early plastic pipework — are especially susceptible. Ground movement, which is common in the clay-heavy soils across much of Essex, can also stress buried pipes over time, leading to joint failures and fractures.
