Petrol garage: 15 litres a minute lost underground
The meter kept moving with every outlet shut. Tracer gas led to a flooded chamber where several mains leaks were repaired.
Commercial leak detection in Buckinghamshire
ADI investigates hidden water leaks in Buckinghamshire’s commercial buildings, from offices in Milton Keynes to business premises in Aylesbury and High Wycombe. Tell us about rising consumption, heating pressure loss or recurring damp so we can plan the right survey.
Commercial water leak investigations in Buckinghamshire
Start with the symptoms and the system involved. The survey scope should reflect how your building uses water.
Buried mains and shared supplies
A leak between the meter and a building can go unnoticed beneath a yard or access road. The investigation takes account of branches to other units, normal water use and the points where pipework can be reached.
Water mains investigationsHeating circuits and concealed pipes
Repeated pressure loss or water appearing on the floor below needs a systematic check. Suitable circuits can be isolated and tested to narrow the search through heating loops, service risers and ceiling voids.
Heating and plant room leaksWashrooms and building water ingress
Water after a busy shift may have a different cause from staining after rain. ADI investigates supply pipes, washroom leaks and roof ingress using tests suited to the affected part of the building.
Roof and building ingress surveysPlan the survey around your premises
Step 1: Describe the loss and the site
Give the postcode, building use and symptoms. Meter readings, pressure records and photographs help the office scope the visit and discuss a quotation and availability.
Step 2: Plan access around operations
Identify who can open plant rooms and affected units. Share pipe plans, induction requirements and any restrictions on water or heating isolation. ADI supplies a risk assessment and method statement (RAMS) before commercial testing starts.
Step 3: Test the suspected system
The engineer checks the symptoms and selects suitable equipment. Separating supplies and comparing readings helps distinguish a hidden pipe leak from other sources of water.
Step 4: Use the findings to plan repairs
The written report and photographs give your facilities team a record to share with the repair contractor or insurer. Agree repair options separately; access, materials and time affect what is possible.
Equipment for hidden commercial leaks
The building and pipework determine the equipment. Background machinery, floor finishes and access points can affect the tests, so a survey may combine several methods.
- Tracer gas
- Sensors detect tracer gas escaping from suitable isolated pipework to help locate hidden leaks.
- Acoustic listening
- Microphones listen for escaping water beneath floors and paving; site noise can affect readings.
- Leak-noise correlation
- Two sensors compare leak sounds to estimate the position along an underground pipe.
- Thermal imaging
- Thermal cameras reveal surface temperature patterns that guide further leak checks.
- Borescope cameras
- Small cameras inspect concealed pipework through existing access points or a small opening.
- Moisture mapping
- Moisture readings map damp areas and guide testing; they do not identify the source alone.
- Pressure testing
- Controlled pressure tests help identify leaking circuits and check completed pipe repairs.

Support for commercial property teams
The building’s use matters as much as the leak location. These are examples of survey situations, not a list of local clients.
Offices and managed buildings
For facilities teams dealing with wet ceiling tiles, riser leaks or shared supplies, a useful starting point is a record of the affected rooms and who controls each part of the system.
Industrial premises and workshops
Buried mains, long heating runs and background machinery can complicate a search. Discuss safe access to yards, working areas and available isolation points when booking.
Hospitality, education and healthcare
Leaks can affect kitchens, washrooms and rooms that remain in use throughout the day. Explain critical water services and any safeguarding or access arrangements so the survey can be scoped appropriately.
Commercial leak detection case studies
Three ADI investigations from Bedfordshire, West Yorkshire and Derbyshire, showing how different commercial water losses were investigated.
School: a buried classroom supply capped off
A hissing classroom and saturated ground led to a leaking desk-tap supply. The school chose to cap the branch rather than excavate.
Hospitality premises: continuous use traced to a urinal valve
The meter showed continuous consumption. Testing found a faulty urinal flush control and dripping fixtures, with no concealed pipe leak indicated.

Buckinghamshire leak survey questions
Does Buckinghamshire coverage include Milton Keynes?
Yes. We use the ceremonial county boundary here, so Milton Keynes and Bletchley are included alongside places within the Buckinghamshire Council area. The town list is illustrative; contact the office with your postcode even if your location is not named.
Can the survey fit around our working hours?
Discuss your operating hours and critical services with the office before booking. Some tests need water or heating isolation, and access to occupied rooms may be required. Availability and the proposed arrangements need to be agreed for your site.
What if several businesses share the water supply?
Tell the office which buildings share the meter and arrange access with the relevant occupiers or managing agent. Water used elsewhere on the supply can affect the readings. The findings can help identify the affected pipework, but they do not determine lease responsibilities.
Does a moving water meter prove we have a leak?
It shows water passing through the meter. Automatic equipment, stored-water systems and other users on a shared supply can also explain movement. Record the readings and known use; do not shut off essential services just to carry out a check.
Will floors or ceilings need to be opened?
Specialist equipment helps narrow the search before opening a surface. An access opening may still be needed for inspection or repair. What is possible depends on the construction, pipe route and access restrictions.
Can we use the findings for a repair or insurance claim?
ADI provides a written report with findings and photographs. It can be shared with your repair contractor or insurer. Check any insurer approval requirements before booking; the survey does not guarantee insurance cover. Ask separately about available pipe repairs and reinstatement.
