A Specialist Leak Detection & Leak Investigation Company
The Leak Hunter is a specialist leak detection and leak investigation company providing fixed-price leak investigation, diagnosis, repair and reporting services throughout London, Surrey, Sussex and Kent.
Founded by Specialist Leak Investigator David White, The Leak Hunter was established as a dedicated specialist leak detection company focused exclusively on locating, diagnosing and resolving hidden leaks. Unlike many plumbing companies where leak detection is one of many services offered, The Leak Hunter was created with specialist leak detection and structured leak investigation as its primary professional focus.
The Leak Hunter specialises in locating, diagnosing and resolving hidden water leaks, central heating leaks, underground mains water leaks, concrete floor leaks, concealed plumbing leaks and complex water ingress across residential and commercial properties.
Every investigation follows a structured, evidence-led methodology that combines engineering knowledge, practical experience and modern non-invasive leak detection techniques to accurately identify the true source of a problem while minimising unnecessary disruption to the property.
Every specialist leak investigation is carried out on a fixed-price basis, allowing customers to understand the cost of an investigation before work begins rather than paying hourly diagnostic charges, regardless of the time required to complete the investigation.
From the initial investigation through to repair, reporting and ongoing support where required, The Leak Hunter provides continuity throughout the entire process. Every investigation is managed with the objective of accurately diagnosing the problem, clearly explaining the findings and helping customers progress confidently towards a practical long-term resolution.
Why The Leak Hunter Was Created
The Leak Hunter was established on the belief that specialist leak detection and structured leak investigation deserve to be recognised as professional disciplines in their own right rather than simply extensions of general plumbing services.
Many hidden leaks cannot be located through visual inspection alone. They require an understanding of building construction, plumbing and heating systems, underground infrastructure, water behaviour and specialist diagnostic techniques. In many cases the visible signs of damage appear a considerable distance from the actual leak, making structured investigation essential before unnecessary disruption takes place.
Before The Leak Hunter was established, many investigations involved properties where multiple contractors had attended, conflicting opinions had been given or unnecessary disruption had already taken place before the true source of the problem had been identified. The company was created to provide homeowners, landlords, insurers and property professionals with a dedicated leak detection company that follows evidence rather than assumption.
Every investigation begins by understanding the available evidence, selecting the most appropriate leak detection methods and methodically eliminating possible causes until the true source of the problem has been identified.
The objective extends beyond simply locating a leak. Every investigation aims to understand why the leak has occurred, how water or gas is behaving within the property and what is required to achieve a practical long-term solution. This investigative approach underpins every service provided by The Leak Hunter, from hidden central heating leaks and underground mains water leaks through to complex trace and access insurance investigations.
Our Investigation Philosophy
Everything The Leak Hunter does is built around specialist leak detection and structured investigation.
Professional leak detection relies upon far more than specialist equipment alone. Successful investigations depend upon engineering knowledge, practical experience and the ability to correctly interpret the evidence gathered throughout the investigation.
Specialist leak detection relies upon engineering knowledge, practical experience and the correct interpretation of evidence rather than equipment alone.
For that reason, every investigation follows the same core principles.
- Follow the evidence.
- Question assumptions.
- Understand the building.
- Minimise unnecessary disruption.
- Explain the findings clearly.
- Support the customer through to resolution.
These principles influence every stage of the investigation, from selecting the most appropriate leak detection techniques through to producing professional reports, recommending repairs and helping customers understand exactly what has been found.
The Leak Hunter combines acoustic leak detection, tracer gas, thermal imaging, moisture mapping, pressure analysis and other specialist leak detection methods according to the type of leak, the construction of the property and the evidence available. Rather than relying upon a single technique, investigations frequently combine multiple diagnostic methods to build a complete understanding of the problem before recommendations are made.
This methodology enables the company to investigate everything from straightforward plumbing leaks through to complex concealed leaks, underground water mains, concrete floor pipework, central heating systems and challenging water ingress that may have remained unresolved despite previous investigations.
Our Approach
The Leak Hunter remains an independent, family-run specialist leak detection company, allowing engineering quality, customer outcomes and long-term solutions to remain the priority rather than sales targets or shareholder expectations.
Customers deal directly with experienced engineers who understand the investigation from the initial enquiry through to the final report, recommended repairs and successful resolution. This continuity helps reduce unnecessary delays, repeated visits and conflicting advice that can often occur when multiple contractors become involved.
The Leak Hunter is an independent, family-run specialist leak detection company built around fixed-price investigations, evidence-led methodology and recognised professional engineering standards.
Rather than simply identifying the presence of a leak, every investigation is designed to establish the true source of the problem, explain why it has occurred and provide customers with a practical route towards a long-term solution.
What We Investigate
The Leak Hunter investigates all major hidden leak types across residential and commercial properties.
Regular investigations include water leak detection, central heating leak detection, underground leak detection, mains water leak detection, concrete floor leak detection, concealed plumbing systems, bathroom and kitchen leaks, gas leak investigations following emergency isolation, intermittent heating pressure loss, unexplained water usage, trace and access investigations and complex water ingress affecting walls, ceilings, floors and structural elements.
Many investigations begin with symptoms rather than an obvious leak. Damp patches, mould growth, unexpectedly high water bills, unexplained water meter movement, dropping boiler pressure, staining, damaged flooring or recurring moisture may all indicate an underlying hidden leak requiring professional investigation.
The Leak Hunter regularly investigates Victorian properties, period homes, modern developments, apartment buildings, commercial premises and multi-property sites, adapting every investigation to the construction of the building, the type of pipework installed and the behaviour of the affected plumbing or heating system.
Some leaks are identified quickly. Others require multiple stages of testing, specialist leak detection equipment and structured engineering analysis before sufficient evidence has been gathered to confidently identify the true source of the problem.
Regardless of complexity, every investigation shares the same objective: accurately identify the source of the leak, minimise unnecessary disruption and provide customers with a clear, evidence-based route towards a long-term resolution.
Today, The Leak Hunter continues to refine its investigative methodology, invest in specialist leak detection technology and develop engineering expertise to improve the accuracy, efficiency and professionalism of every investigation undertaken.
How We Investigate Hidden Leaks
Every hidden leak presents a different challenge. No two properties are constructed in exactly the same way, and no two investigations follow an identical path. The age of the building, construction methods, previous alterations, pipe materials and the behaviour of the affected plumbing or heating system all influence how an investigation should be approached.
Successful leak detection begins with understanding the building before selecting the most appropriate investigative methods.
For that reason, The Leak Hunter does not follow a fixed checklist or rely on a single piece of equipment. Every investigation begins by gathering evidence, understanding the symptoms and building a structured understanding of how the property and its services are behaving before selecting the most appropriate leak detection techniques.
Every investigation is tailored to the individual property, selecting the most appropriate leak detection methods according to the available evidence rather than following a fixed process.
The objective is not simply to locate a leak, but to understand why it has occurred, how the building or system is behaving and how the problem can be resolved with the least possible disruption.
As new evidence becomes available throughout the investigation, the working theory is continually reviewed, challenged and refined until the true source of the problem has been confirmed.
Selecting the Right Investigation Methods
The Leak Hunter continually invests in specialist leak detection technology because successful investigations depend upon selecting the right investigative technique at the right time.
Different investigative techniques provide different types of evidence. Thermal imaging identifies temperature anomalies, tracer gas confirms concealed leaks, moisture mapping establishes how water has travelled through a building, while acoustic techniques and correlation help locate hidden leaks that cannot be seen. Each investigative method contributes evidence that supports the overall investigation.
Modern leak detection technology provides evidence. Accurate diagnosis depends upon correctly interpreting that evidence.
No single leak detection method is suitable for every investigation. Successful investigations frequently combine several investigative techniques before reliable conclusions can be reached.
Technology supports engineering judgement. Professional judgement determines how that evidence is interpreted.
Investigation Through to Resolution
Locating a hidden leak is often only one stage of resolving the overall problem.
Leak detection is only one stage of resolving a hidden leak. Understanding the cause, carrying out repairs, recommissioning systems and confirming successful operation are equally important.
Where appropriate, The Leak Hunter is able to investigate, repair, recommission, test and return systems to normal operation, reducing the need for customers to coordinate multiple contractors and ensuring continuity throughout the investigation.
Unlike companies that simply identify the approximate location of a leak before leaving site, every investigation is designed to provide customers with a clear understanding of what has been found, why it has occurred and what practical options are available moving forward.
The Leak Hunter supports customers from investigation through to repair, recommissioning and long-term resolution wherever possible.
Where repairs are undertaken by The Leak Hunter, systems are tested following completion to confirm the repair has been successful before being safely returned to normal operation.
Professional Standards
Professional standards form an important part of every investigation undertaken by The Leak Hunter. Industry memberships and recognised engineering accreditations demonstrate the company’s commitment to safe working practices, recognised engineering standards and continual professional development.
Gas Safe registration allows The Leak Hunter to safely investigate, repair, recommission, test and certify gas and central heating systems where required, allowing many investigations to progress from diagnosis through to a fully operational heating system.
WaterSafe approval demonstrates recognised competence when working on wholesome drinking water systems, underground mains water supplies and internal water pipework, allowing investigations and repairs to be completed in accordance with recognised industry standards.

Professional memberships and industry accreditations support The Leak Hunter’s commitment to recognised engineering standards, safe working practices and continual professional development.
Experience Still Matters
Leak detection technology continues to evolve, becoming more accurate and more capable every year. However, successful investigations still depend upon engineering knowledge, practical experience and professional judgement.
Two engineers may have access to exactly the same equipment yet reach very different conclusions. Understanding how buildings behave, recognising investigation patterns and correctly interpreting evidence often makes the difference between locating the true source of a hidden leak and simply treating the visible symptoms.
Technology identifies evidence. Experience determines what that evidence means.
For this reason, The Leak Hunter continues to invest in investigative methodology, specialist leak detection technology and ongoing engineering development. Every investigation contributes to refining the company’s knowledge, improving the accuracy, efficiency and professionalism of future investigations.
The Leak Hunter combines specialist leak detection technology, engineering knowledge, practical experience and recognised professional standards to deliver evidence-led investigations from diagnosis through to resolution.
Every investigation undertaken by The Leak Hunter shares the same objective: identify the true source of the leak, minimise unnecessary disruption and provide customers with a practical route towards long-term resolution.
Experience Built Through Investigation
The Leak Hunter’s investigative methodology has been developed through practical experience gained across a wide range of specialist leak investigations involving residential, commercial and managed properties. Every completed investigation contributes to a greater understanding of how hidden leaks behave, how buildings respond to water movement and how evidence can be used to accurately identify the true source of a problem.
The company investigates every major hidden leak type, including water leak detection, central heating leak detection, underground leak detection, mains water leak detection, concrete floor leak detection, concealed plumbing systems, complex water ingress and intermittent pressure loss.
The Leak Hunter investigates every major hidden leak type, adapting every investigation to the construction of the building, the behaviour of the affected system and the available evidence.
From Victorian and listed buildings through to modern homes, apartment developments, commercial premises, schools and managed properties, every building presents different engineering challenges. Rather than following a standard process, investigative methods are adapted to suit the property and the evidence gathered throughout the investigation.
Some investigations are completed quickly. Others require multiple stages of testing before sufficient evidence has been gathered to confidently identify the true source of the problem.
Complex Leak Investigations
Some hidden leaks are straightforward to locate. Others require a structured investigation before the true source can be confidently identified.
Water rarely appears where the leak originates. Understanding how water travels through different building structures is often the key to identifying the true source.
Water can travel through concrete floor slabs, structural cavities, suspended floors, service risers and concealed voids before eventually becoming visible elsewhere within a building. This movement can result in damage appearing several rooms, floors or even neighbouring properties away from the original leak.
The Leak Hunter regularly investigates properties where previous repairs have been unsuccessful, multiple contractors have attended or visible symptoms have resulted in the wrong areas being investigated. By following evidence rather than assumptions, investigations are designed to identify the true source before repairs begin, reducing unnecessary disruption and increasing confidence in the final diagnosis.
Some of the most challenging investigations involve identifying leaks where the visible damage is many metres from the true source.
Supporting Property Owners & Professionals
The Leak Hunter provides specialist leak detection and leak investigation services for homeowners, landlords, managing agents, surveyors, insurers, loss adjusters, commercial organisations and public sector clients.
Different investigations require different outcomes. Some projects require a hidden leak to be accurately located. Others require detailed engineering reports, photographic evidence, repair recommendations, insurance documentation or technical support for ongoing building works.
The Leak Hunter provides evidence-led investigations supported by professional reporting for homeowners, surveyors, insurers and property professionals.
Professional reports are prepared where required to support insurance claims, repair planning, contractor coordination and property management, helping investigation findings be clearly understood and acted upon with confidence.
