About ADI Leak Detection | Non-Invasive Leak Detection Specialists

ADI Leak Detection is a UK water leak detection company that locates and repairs hidden leaks in central heating, plumbing, water mains, drainage, swimming pools, roofs and building structures using non-invasive methods: tracer gas, acoustic listening, leak correlation, thermal imaging, borescope cameras and moisture meters. ADI Leak Detection was founded in High Wycombe in 2011 and has 25 leak investigation engineers covering England, Scotland and Wales.

Who is ADI Leak Detection?

ADI Leak Detection was started by one engineer in High Wycombe and is still run by people who came up through the business. The office team speak to every customer before an engineer is booked, and the engineer who attends is the one who writes the report. That is deliberate: when a leak is costing money or damaging a home, people want a clear answer from someone who has actually looked at the problem.

ADI Leak Detection vs a plumber, the water company and an insurer’s contractor

	ADI Leak Detection	General plumber	Water company	Insurer-appointed contractor
Finds the leak before opening up	Yes, tracer gas, acoustic, correlation, thermal, borescope	Usually not, exploratory opening of floors/walls	Only on their side of the boundary; not inside the property	Depends on contractor; often opens up first
Scope	Plumbing, heating, mains, drains, pools, roofs, structure	Plumbing and heating	Supply pipe up to the stop tap on the road side	Whatever the policy’s trace-and-access clause covers
Insurance-ready report	Yes, photo and video, written by the attending engineer	Rarely	No	Yes, but written for the insurer
Repairs	Plumbing, heating, mains, pools, guaranteed	Yes	Their pipe only	Sometimes; often a separate contractor
Pricing	Fixed price per service, quoted first	Hourly, open-ended	Free on their side of the boundary; policies on the customer’s supply pipe vary by company	Paid by insurer, less policy excess
No Find No Fee	Plumbing and mains leaks (0.5 L/min+, mains up to 30 m)	Rarely offered	n/a	n/a
Time to appointment	Same or next day in most areas	Varies by plumber and workload	Attends its own network, not a leak inside the property; timescales set by the company	After the claim is approved, so typically longer

ADI Leak Detection's history

Adrian - Founder of ADI Leak Detection — **Adrian Morgan** founded ADI Leak Detection in 2011 with a plumbing background and a conviction that most leaks could be found without ripping out floors and walls. He was an early adopter of tracer gas, acoustic and thermal methods, built several of the company’s own pool and pipework tools, and took ADI from a one-man local service to a nationwide operation. After Adrian’s passing in 2024, ADI Leak Solutions Ltd was incorporated to carry the company forward. The process he built, and the standards behind it, are still the ones every ADI engineer works to.

Monique Dray - Managing Director — **Monique Dray** joined ADI in 2016 and became Managing Director in 2024. She ran the company’s operations and customer side for years before that, which is why the business kept running steadily through the transition following the loss of Adrian Morgan in 2024. Her focus is on doing the job properly: honest quotes, engineers who turn up when they said they would, and reports customers can rely on for an insurance claim.

How ADI Leak Detection finds a leak

Call 0800 731 3843. A technical advisor asks about the symptoms (rising bill, pressure loss, damp, meter movement) and which pipework is affected, then confirms the service, price and the earliest engineer slot.
Engineer visit. A locally based ADI engineer arrives with the equipment set for that leak type and isolates the system under test.
Non-invasive tracing. Depending on the system: tracer gas is introduced and detected at the surface; acoustic microphones and a correlator locate the sound of escaping water; thermal imaging maps heat loss; borescope and moisture readings confirm the exact point.
Pinpoint and mark. The leak location is marked on site and explained to the customer before any repair is discussed.
Repair (plumbing, heating, mains and pools). Where the customer wants the leak fixed, the same engineer can carry out the repair, guaranteed.
Report. An insurance-approved report with photographs and video is issued by the attending engineer.
