ADI Leak Detection, non-invasive leak detection in England, Scotland and Wales

ADI Leak Detection is a British company dedicated to locating and repairing hidden water leaks using non-invasive methods. Its work covers central heating systems, plumbing installations, water mains, drainage networks, swimming pools, roofs and building structures. The firm presents itself as the UK's number one leak detection specialist and supports this claim with the volume of reviews shown on its website.

The company operates under the legal name ADI Leak Solutions Ltd, registered in England, and uses ADI Leak Detection as its trading name. It was founded in High Wycombe in 2011, starting with a single engineer; according to the material consulted, it is still managed by the same person and has 25 leak investigation engineers covering England, Scotland and Wales.

Leak location services by type of installation

The catalogue is organised according to the affected element, as each problem requires different techniques and equipment. Technical advisors talk to the client to determine which service is most suitable, and the engineer then combines the appropriate equipment to locate the source.

• Water mains: detection under homes, buildings, gardens, paths or driveways, through materials such as grass, soil, gravel, concrete and asphalt.
• Central heating: location in radiators, pipes and underfloor heating systems, in both residential and commercial properties.
• Hot and cold water pipes: inspection in walls, floors and ceilings without destructive works.
• Bathrooms: inspection of showers, baths, sinks, toilets and pipework behind walls and under floors.
• Ceilings: tracing water ingress from roofs, pipes or upper floors.
• Swimming pools: detection in liners, pipes, filters and pool structures.
• Roofs: identification of leaks through tiles, flashings, gutters and the roof structure.
• Drains: investigation of leaks and blockages using CCTV camera inspection.
• Irrigation systems: inspection of sprinklers, pipes and irrigation networks.

Technology used in the investigation

The company works with a set of tools that allow leaks to be detected without breaking surfaces. These include tracer gas, acoustic listening equipment, leak correlation, thermal imaging, borescope cameras, moisture meters, pressure testing, endoscope inspection, leak dye testing and underwater inspection in swimming pools. For roofs, drone inspection is also used, and for drains, CCTV camera surveys.

Repair and insurance reports

In addition to locating the problem, ADI Leak Detection repairs leaks in plumbing pipes, central heating systems and swimming pools. The firm issues trace and access reports approved by insurers, written by the engineer who attended the property and supported by photographic and video evidence. As it explains, a claim for "Trace and Access" or "Escape of Water" is likely to require a copy of that report, and water damage is covered by buildings insurance.

Clients and coverage

The services are aimed at homeowners, landlords, tenants and businesses. In the commercial field, the company can provide a risk assessment and a method statement, and it has £5 million public liability insurance covering its staff and the properties. Among the profiles served are industrial facilities, facilities and property management companies, and insurance companies.

The company states that it has engineers in all areas of the UK and provides service in England, Scotland and Wales. Its stated goal is to locate and repair the leak on the same day.

Conditions of the "no find-no fee" guarantee

The website describes a "no find, no fee" guarantee with specific conditions: it applies to the investigation of a single leak in an individual property, the leak must be losing at least half a litre of water per minute, and coverage is limited to leaks in hot and cold water pipes and water mains up to 30 metres. Central heating, structural and swimming pool leaks are excluded.

Track record and ratings

The firm reports more than a decade of activity in leak detection and shows a score of 4.7 on Trustpilot from more than 1,500 reviews, as well as more than 1,000 five-star ratings. These figures, like the number of engineers, are dated September 2026 on the page itself.
