About ADI Leak Detection
ADI Leak Detection has been finding hidden leaks since 2011. It is still run by people who came up through the business, and the engineer who attends your property is the one who writes your report.

Who you are actually calling
ADI Leak Detection was started by Adrian Morgan in High Wycombe in 2011, by one engineer with a van. It is a trading name of ADI Leak Solutions Ltd, and it now runs 25 leak detection engineers across England, Scotland and Wales, completing around 5,000 jobs a year.
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 sounds like a small thing until a leak is costing you money. It means the person who explains the result has stood over the hole, and it means your insurer or your water company can put a question to the engineer who wrote the document rather than to a call handler reading it off a screen.

- Mark JonesTechnical Manager. Signs off every new engineer before they work alone.

How an engineer gets on the van

- ADI’s own training on tracer gas, acoustic correlation and thermal imaging.
- Shadowing an experienced engineer until Mark Jones, Technical Manager, signs the training off.
- A CSCS card, so the same engineer can work on a commercial site as well as a house.
