About New Build Leak Detection
New Build Leak Detection, a specialist service from ADI Leak Detection. The people who answer the phone, the engineers who turn up and the company on the invoice are all ADI.
Who ADI Leak Detection are
ADI Leak Detection was started in 2011 by its founder, Adrian, as a specialist leak detection company at a time when most leaks were still found by opening things up. He was an early adopter of non-invasive methods and built the business from a local service into a national one. After Adrian died, ADI Leak Solutions Ltd was formed to carry the company on under the same name and the same principles. It is led today by managing director Monique Dray, who has been with the company for more than ten years.
Today ADI runs more than twenty-five leak investigation engineers across England, Scotland and Wales, supported by an office team in High Wycombe that handles booking, scheduling, reports and customer questions. ADI states that its engineers are all qualified and registered plumbers; it does not offer general plumbing, and it does not repair roofs or building fabric.
ADI's own website carries more than a thousand five-star reviews on Trustpilot; the independent profile showed a TrustScore of 4.7 from 1600+ reviews when we checked on 14 September 2026.
Why new build homes need specialist leak detection
A new home leaks in its own ways. The pipes are plastic with push-fit joints, the heating is often buried in the floor, everything is sealed behind fresh plasterboard and screed, and a builder and a warranty sit in the picture alongside the owner. The questions change with it: will this wreck my new floor, who pays, will the builder accept the report, can you come out before the plot is handed over.
New Build Leak Detection exists to answer those questions in one place. Some of ADI's engineers came to leak detection from new build plumbing, one of them after fifteen years fitting out new homes. The service, the engineers and the terms are ADI's throughout.

Booking a leak survey with ADI
Every new build job begins with a conversation. The office team asks about the house, the symptoms and the access, works out which kind of investigation fits, quotes it, and books the engineer. They stay in the loop through the visit and send the report afterwards. If the builder, the warranty provider or your insurer has a question about the findings, they are the people to ring.

Recent Trustpilot reviews of ADI
Read the full review“Hamaad from ADI was great. He was very thorough with his work and communicated everything very clearly. He was able to locate the leak and provided a detailed report that could be shared with my insurer. He went above and beyond to answer questions about my insurance claim from both me and my insurer. I'd highly recommend their services.”
Read the full review“We had a major water leak of approximately 220 litres per hour and, with a holiday booked only a few days later, we urgently needed someone to find and repair it. […] Frank arrived at our house. He was extremely polite, professional and clearly very experienced. He quickly set up the equipment, carried out a tracer gas test and pinpointed the leak to an area just outside our garage underneath the driveway. […] The whole job, from arriving at our house to finding and repairing a 220 litre-per-hour leak, was completed in around three hours.”
