Excellent service. Simple as that. Contacted them about a leak in our central heating system and they explained their process for investigating to find it. Hamaad came out with all the equipment and had located the suspect area in less than an hour and it was all fixed and checked out really quickly after. It might seem like a high price for this service but it really minimises the amount of upheaval this type of problem can cause. ADI, and particularly Hamaad, you’re a star!
Brian McCormack, 12 April 2025 Murieston, West Lothian engineer: Hamaad Janjua
Thorough, professional and tidy
Impressed. Our engineer, Robert, showed up on time and got started on finding the leak. Our boiler had been losing pressure, and although we suspected a leak in the lounge, we needed confirmation (and we also needed to know there were no others). He found the leak, checked the rest of the house, dug into our concrete floors (with minimal mess) and replaced two lengths of copper pipe. He was thorough, professional, tidy and explained what he was doing throughout. He also made sure we saw exactly how and where the old pipes had failed. A good experience and glad to have it sorted.
Wes Nicholson, 26 March 2025 Matlock Bank, Derbyshire engineer: Robert Gires
Perfect from start to finish
Robert arrived on time and was very polite and respectful of my property. He answered all the many questions I had and explained everything he was doing whilst doing it and next steps. We had a leak in the heating system - boiler kept dropping pressure -Once he drained the heating system he pumped some air and then gas. He found the leak almost immediately in a very hidden place inside our built in wardrobe! Robert is very thorough and will definitively ask for him if I have the same problem again (but hopefully not!!) thanks Robert you saved us a lot of £££££
Alessia, 24 May 2024 Chichester, West Sussex engineer: Robert Gires
Gabor was trustworthy and courteous
Gabor was very courteous, he explained what he was going to do and after I had explained the history he proceeded with his investigations. He removed his shoes, every time he was in the house (our boiler is in the garage) and on finding the leak demonstrated his findings and gave us options for resolving the leak. I'm a Chartered Engineer so I would have spotted any nonsense but he was as straight as a die, very trustworthy. Thank you Gabor.
Michael, 6 November 2025 Dodd Fell, Wiltshire engineer: Gabor Weber
Professional, efficient and effective service
Very helpful and professional from first contact with the call centre through to the plumber sorting the leak. Extremely prompt service - they came the very next day, which meant we didn't have to do without heating over the weekend! The plumber, Gabor, was very informative, keeping us abreast of what he was doing, and why, throughout the process. He found the leak, repaired it, and our central heating is now back in business. Thank you!
Rowena Love, 28 February 2026 Welwyn, Hertfordshire engineer: Gabor Weber
James is an asset to ADI-pipe leak/fix
James arrived on time, used high tech equipment to locate leak, then fix pipe leak, ensuring carpets etc covered. He then went above and beyond to fix an air lock and get my boiler, pressure and radiators going again, which wasn't straight forward. Also referred to concept to help deal with insurers for ceiling repair. Very friendly, professional and efficient, he is an asset to ADI!
Vanessa Foster, 14 December 2023 Tunstall, Kent engineer: James Bexter, James Hunter
Very Happy customer
ADI and in particular Mark Pavitt were brilliant. We had a particularly tricky situation where a builder had installed underfloor heating, completed the kitchen on top and then a leak was discovered. Mark was very polite and extremely thorough and patience working through all the various variables to find the issue. So happy its fixed and would certainly recommend.
Andrew McDonnell, 7 November 2024 Lea Bridge, Greater London engineer: Mark Jones, Mark Pavitt
Failed Push Fit Cap = Underfloor Leak
The engineer, Mark Pavitt was very personable and his technical skill and knowledge was very good, explaining everything in detail throughout the process. The leak was fixed with minimum disruption to the floor area, which turned out to be a failed push fit connection to a previously removed radiator. I would recommend to others
Ian Hudson, 1 October 2024 St John's, Kent engineer: Mark Jones, Mark Pavitt
ADI were excellent in every way. Once l had completed a certain amount of investigation it was apparent that l had a water leak, the size of my water bills were extreme. Christian from the office who l had an initial conversation was extremely helpful, professional and detailed on the service that ADI provided. Emails were prompt following the call and all in all it was a great experience. Robert turned up on the day and a continued success story. He was brilliant in every way. Courteous, hard working, and would not be beaten by this leak. He came, he saw and he conquered… literally 🤩 🤩.
Alan, 21 February 2025 Hardstoft, Derbyshire engineer: Robert Gires
Water trickling from front of house/driveway
Hamaad arrived at the exact time that had been arranged to investigate water trickling at the front of our property/driveway. He set to work testing all the water pipes exactly as had been explained to me by Dave when I booked the appointment. From start to finish of the investigation Hamaad was outstanding. Nothing was too much trouble for him and he even squeezed through a small hatch to look under the floors to check for any signs of water. He is an asset to ADI. Unfortunately the problem was not resolved as the leak, wherever it is originating from, is not from our property.
Hazel Ward, 21 January 2025 West Kilbride, Ayrshire engineer: Hamaad Janjua
Mains water leak under kitchen tiled floor
From the initial call with a waterleak in my house the description of what ADI could do calmed my anxiety down a bit. When Gabor visited, he was very relaxed and professional and filled me with confidence. The leak was detected quickly and when he said he could repair it, I was so happy. He fixed it, tested it and tidied up. Yes there is a big hole in my floor but how else could he get to the mains pipe. Job done, and we now have zero leaks and the drying process starts.
Dax Ward, 6 February 2024 Botley, Hampshire engineer: Gabor Weber
External mains water supply leak
We had an external mains water supply leak with no idea where the break was. Vincent the engineer turned up as arranged, and used specialist equipment to detect the most likely point of the leak, which turned out to be situated under a concrete drive. It turned out to be absolutely pinpoint accurate, only requiring a small hole to fix the problem. Saved us a huge amount of time and work.
Mr Palmer, 25 March 2025 North Ascot, Berkshire engineer: Vincent Morgan
Fantastic service from everyone at ADI!
Fantastic service from everyone! Gabor especially, who came out and was professional, friendly and very efficient! He had the leak identified in no time and fixed shortly after! Phew!! I had visions of my garden and patio walkways having to be dug up but luckily the leak was close to the water meter. Well done ADI!
Tom Van Der Hoven, 25 November 2025 Ramsbury, Wiltshire engineer: Gabor Weber
These guys did a fantastic job.
These guys (adam and vince) did a fanastc job of finding and fixing a burst mains pipe underneath the floor, inside the house. Whilst they had to use a nematic driller/hammer to get to the issue. They did with minimal damage, and I'm amazed they manged to locate it so well. Started 9:30. Fonished by 3:30. Thanks.
Andrew Oliver, 24 April 2024 Wormleighton, Warwickshire engineer: Adam Regan, Vincent Morgan
Arthur turned up just before the allocated time, which is always good. My water supply system is not easy. I live on a slope & the water meter is 20 metres from the property so the leak I had could have been anywhere down that slope under the drive. Arthur checked out the stopcocks in the kitchen & the garage and proceeded to do all the relevant checks. It turned out to be a pipe that had a split buried under 600mm of sharp stone & thick concrete in my porch. Not an easy think to find & he then fixed it. I have no hesitation in recommending this company for an efficient job. Tony
Tony Burt, 10 March 2026 Worton, Wiltshire engineer: Artur Sowa
Grant turned up early and explained what he’ll be doing and the processes involved. He was extremely polite and professional. Anglian water had visited briefly and said the leak was on the property and was not their responsibility to fix. Grant located the leak and it was close to the recently installed water meter and on the pavement so Anglian water’s problem. We received the video and report the following morning. All in all an excellent service.
Alun, 4 October 2025 Wethersfield, Essex engineer: Grant Corney
First time using ADI, reliable and efficient. Offered fixing the next day to our emergency appointment. Grant arrived early next day, professional and friendly, could tell does what he does with passion and eagerness, he quickly located the source of leak based on our information provided, and avoided to open up bathroom wall with professionalism and good knowledges, cannot recommend him enough!
Yunfei, 14 October 2025 Barrow Hill, Kent engineer: Grant Corney
Excellent service
Excellent service. Our engineer, Grant, arrived early. He was charming, well presented, friendly and efficient. He assessed the situation and traced the leak quickly. He made minimum impact in the shower where he had traced the pipe leak, sealing it off and cleaning up afterwards. Good job done.
Nicholas Brown, 23 May 2024 Biggin Hill, Greater London engineer: Grant Corney
On time and on budget
Operative arrived on time - to the minute - and was clean, tidy and polite. Hamaad detected a leak in my bathroom pipework which was threatening my kitchen ceiling below, got the parts and fixed the problem. He cleaned up after the job too. 100% satisfied and would definitely recommend ADI.
Shelagh Fraser, 1 January 2025 Linlithgow, West Lothian engineer: Hamaad Janjua
We had a leak behind tiles in our bathroom and ADI leak Detection were able to arrange one of their plumbers to call the next day. Using his specialist equipment he was able to identify exactly where the leak was and resolve the issues without having to remove tiling. Mark did an excellent job and kept me informed as to what was being done. One hopes not to need to use these services but ADI leak detection was certainly the right choice having had a problem.
Mr Carpenter, 20 May 2025 Rustington, West Sussex engineer: Mark Jones, Mark Pavitt
Leaking En-Suite
Hamaad from ADI came out today to investigate a leak in our en-suite. He was very knowledgeable and kept me informed the whole time as to what he was doing and why. Hamaad was polite and friendly and I would recommend this company.
Gabor and Kyle arrived the next day after requesting help. They immediately got on with the job, detected the leak and fixed it. The water was leaking in considerable quantities through the ceiling into a garage with a bathroom above. The leak was actually found in the loft space above the bathroom and was not visible but water was running down pipes hidden behind a wall. We would certainly recommend this company. Gabor and Kyle were extremely efficient and pleasant, explaining their actions. Without their specialised equipment the leak would not have been found so quickly.
Alan, 26 April 2024 engineer: Gabor Weber, Kyle Storkey
Not cheap but from my perspective good value for a professional job by folks with experience. Spoke on phone with Monique who explained the service and costs and sent over terma ahead of the engineers visit. Adam and Gabor very professional and found the issue after a time of testing and checking. Kept us informed during the porcess Issue was fixed on the day . Highly recommend. I would not hesitate to recommend these folks when you need
Helairmike, 17 June 2024 engineer: Adam Regan, Gabor Weber
Pool leak
Matt and Vince arrived to find our pool leak and methodically went through the history and symptoms of the issue. They then completed a series of pressure tests and identified the issue where previous companies had failed. On a cold day with a less than perfect pool water condition (down to us) they were professional and engaging on the fault found and the way forward. Would be happy to recommend and use them again if we need to.
Adam Hewitt, 9 March 2022 engineer: Matthew Barron, Vincent Morgan
If Carlsberg did leak detection
ADI from the start were professional and very clear regarding costs & potential further costs. The excellent engineer Matt called me with ETA on day of visit & was simply 11/10 in finding our swimming pool leak and checked every outlet for further issues. Worth every penny and the report received afterwards satisfied our insurance company. This company are unique and deserve praise for the services they provide
Jason Farmer, 11 October 2022 engineer: Matthew Barron
Would use and refer ADI 5 star service every time.
Have referred ADI to a few of our customers now after I have found their swimming pools to be leaking and ADI have come in and pin pointed where the exact leak is. Matt and Adam from ADI are very knowledgeable and very professional in what they do, they will test every possible fault and repair and make good. 5 stars for me and will use and refer every time.
Oasis Pools and Hot Tubs, 24 March 2023 engineer: Adam Regan, Matthew Barron
Excellent company that found the leak at last
Having tried another pool leak company, and been led up the garden path by them, I was nervous of trying another. I shouldn’t have worried from the minute I called ADI they were professional, efficient and they found the leak. Dave at the office we very helpful and Matt and the team took time finding the three problems and fixed them. Thanks so much
caznewland, 23 July 2024 engineer: Matthew Barron
Tricky swimming pool leak
Large pool losing water at a rate of knots. Adam and Danny established leak was in the return pipes, found the leak through gas tracing in a difficult to access location, sealed off the pipe from within the pool (with aid of diving gear) and managed to effect a complex repair the next day with minimal disruption
John B, 4 June 2024 engineer: Adam Regan, Danny O'Mahony
A huge thank you to Kristof. Who arrived at our property at stated time 9.30 and worked really hard at finding a leak on the waste pipe of which a previous firm had not fixed properly. He left the site a clean and tidy at kept us informed about what he was doing throughout the job. He is truly a very hard worker and a credit to your company and would definitely recommend
Louise BURKETT, 25 October 2024 Angmering, West Sussex engineer: Krzysztof Kobylinski
Waste pipe leak in kitchen
Hamaad gave a great service . Informed me fully of placement of leak from waste pipe .Completed the repair which unfortunately could only be accessed by cutting away a section of kitchen flooring . Excellent service overall
Alan Brown, 23 February 2026 Inverkip, Renfrewshire engineer: Hamaad Janjua
Recommend
The guys that came to detect a leak were extremely helpful and went above and beyond what was needed.(Mark Jones attended) They gave advice and discussed what the issue was with a leaking waste pipe. With fixed pricing plans for a day rate it helped with no grey areas on how much it would cost (other leak detection companies charge per half an hour)
laura brown, 12 October 2024 engineer: Mark Jones, Mark Pavitt
Great service today
Great service today and very thorough at diagnosing the problem which was quite a complex issue to identify. Good communication from Paul the engineer and clear a lot of previous experience which was helpful. Our issue was an internal waste pipe had become disconnected from the kitchen sinks and water was draining water under the house. Would recommend.
Helen Duckworth, 6 August 2025
Finally someone who knows what they are doing. Excellent. Connor came to deal with the leak found and fixed my waste pipe leak on the same day. Are pleased Thank You will recommend.
Kyle was professional, efficient and extremely polite and personable. He found the source of the leak into our kitchen from a flat roof above where several other builders had failed. He tested and retested in a thorough and comprehensive way and explained and demonstrated what was causing the ingress in a way we understood. We would thoroughly recommend him.
Paul King, 5 January 2026 Broadstairs, Kent engineer: Kyle Storkey
Leaking flat roof in orangery.
The company from fist contact through to the job completion were first class in their communication and explanation as to how things would go. The engineer Daniel was again first class, arrived bang on time polite and explained everything he was doing and why. After several test the problem was ultimately found and a plan for resolution was discussed. I would absolutely 100% recommend and use ADI again!
Andrew Stevens, 29 December 2023 West Tilbury, Essex
ADI and Mark Pavitt in particular were absolutely first class. Professional, polite and on time. Mark identified the problem quickly and advised me on the next steps and what work would be needed structurally to sort out our failing chimney stack. I am delighted I used ADI and am happy to recommend them to others.
Customer, 18 May 2021 engineer: Mark Jones, Mark Pavitt
We noticed some damp patches on a ceiling so contacted ADI. Grant arrived on time and was very friendly and courteous, he quickly discovered where the leak was and was able to fix it for us there and then. Excellent service, highly recommended and would definitely use again if needs be
Sally Porter, 29 May 2024 Upper Cambourne, Cambridgeshire engineer: Grant Corney
Highly recommend ADI pro leak detection.
We used ADI to determine the cause of our rising damp and flooded sub floor. Mathew Barron was our engineer and was very pleasant and proffesional. Mathew was thorough in determining the cause of our damp and explained what he was doing during the detection. Hi tech equipment was used i.e thermal imaging cameras and drones. A full report from ADI was sent to me within three days and a very proffesional report it was too. This was then forwarded to our insurers. I would highly recommend ADI pro leak detection.
Guest, 18 October 2024 engineer: Matthew Barron
Excellent and Professional Service
The engineer who attended our property was extremely professional, very competent and pleasant, explaining everything we asked about. The leak was located precisely, quickly and repaired promptly. Structural work to the building to reach the pipe beneath the ground floor was also undertaken professionally and to a very high standard. Resulting in minimal damage resulting from limited invasive works.
We work across England, Scotland and Wales. The reviews below are the
ones we can tie to a confirmed job address, grouped by the region the

Great leak detection company
The engineer, Mark, arrived and very quickly found the leak in the floor of my downstairs toilet. He was extremely professional and took the time to explain the whole process clearly, which really put my mind at ease. He patiently answered all my questions and even spoke to my insurance company on my behalf, which I found incredibly helpful. The leaky pipe was fixed, and Mark left the area clean and tidy. There’s still more work to be done but the main source of the problem is resolved. Thank you, ADI for a very good service,
Kathy, 24 January 2026 Penton Hook, Surrey engineer: Mark Jones, Mark Pavitt
Brilliant service
Mark was brilliant, he thoroughly assessed the situation, checked in a very uncomfortable crawl space under the property and actually located the leak (something Southern Water have failed to do 3 times). Bless him, he worked very hard in some extremely challenging weather, but most importantly he found & fixed the issue on the day. We cannot thank him and ADI enough, after three long years we are now able to sell my late mothers property safe in the knowledge there is no more leak.
T Wheeler, 12 September 2025 South Lancing, West Sussex engineer: Mark Jones, Mark Pavitt
Super speedy and efficient service
From the initial telephone conversation to completion of the leak detection and fix, ADI really know what they are doing. Initially I had a good conversation about what to expect and how to deal with insurance. Then the engineer, Mark Pavitt was great. He kept me informed of the time he would arrive and when here, located the leak and fixed the pipe very quickly. Really friendly, helpful guy and a very efficient service. All sorted and very happy customer. Would definitely recommend. Thanks.
Angela Ahmed, 12 March 2025 Caterham, Surrey engineer: Mark Jones, Mark Pavitt
Brilliant!
What a brilliant company and Gabor who attended was fantastic, he was so professional and efficient , listen carefully to me whilst I a non plumber(!) tried to explain the issues, he worked diligently to locate the issue and then solved it, I could not recommend the company more, from my first phone call they worked efficiently and did exactly what they said they would do, Gabor arrived on time and solved the problem. Thank you Gabor for being a star.
Lucinda McFarlane, 5 February 2024 Clanfield, Oxfordshire engineer: Gabor Weber
Extremely happy with the service
Very happy with the service, the engineer (Kristof) was very tidy and organised, he even helped us move our kitchen units, which shouldn't be his job really. The leak was under the floor, so a hole had to be made to get access to the leak, but the hole was made quite small and carefully, the damage was so much minimum than we expected. A big relief and really grateful we found ADI. Definitely will recommend without a shadow of doubt.
lei dong, 21 March 2025 West Stratton, Hampshire engineer: Krzysztof Kobylinski
Fundamentally, the engineer (Mark Pavitt) identified the source of the leak, repaired it and had our house back up and running within the same day. As part of achieving this, he kept the damage to a minimum (only having to cut out sections of the kitchen plasterboard ceiling). He cleaned up the debris, was polite, cheerful and informative of root cause and actions throughout the day. I think the key to success is having an engineer that has expertise in both leak detection and plumbing.
Mr R Cregan, 26 November 2025 Batford, Hertfordshire engineer: Mark Jones, Mark Pavitt
Fabulous leak detection and repair service
Having had another leak detection firm charge me a fortune to try and tell me there was no leak ADI came to visit today. Gabor our engineer was brilliant and located the leak within a couple if hours under the floor in the hallway. He then dug out the area and replaced the area of pipework solving our problem. This has been going on for months, I only wish we had found ADI earlier. Highly recommended.
Professional, efficient with prompt response to call out
It has been easy and quick to arrange for a quote and the call out. Engineer that detected the leak, Grant, was very polite, respectful of the property and walked us step by step through the process. He presented us with options on approach to leak detection and potential solutions to fixing it. The quote has been made clear at each stage of booking and decision making.
Justyna Szczepaniak, 13 February 2025 South Ockendon, Essex engineer: Grant Corney
Quick, Efficient and pleased with ADI
Very, very pleased. The service by ADI second to none. From the initial contact to detecting and fixing the leak, Grant and Scott were very professional, friendly and went through the whole process, assuring us that we would have a successful conclusion. I highly recommend ADI if you need to someone to find and fix an issue with leaks. Many thanks.
R Lagden, 2 May 2025 Wormingford, Essex engineer: Grant Corney, Scott Hardcastle
A heating leak under concrete floor.
The Engineer Scott attended to locate a heating pipes under a concrete floor , he identified the area using a thermal imaging camera and then used a breaker to expose the pipe work and found the problem. He then drained the system and replaced the pipe. He was excellent and did a brilliant job. Highly recommend and a credit to ADI. Thank you.
Long, 4 March 2025 Tibenham, Norfolk engineer: Scott Hardcastle
From booking the appointment to the visit, it was very professional & friendly experience. Caroline who took my call & booked the appointment was great. She listened carefully to my concerns & explained the steps in detail. The engineer Grant was fantastic. He thoroughly explained everything & took the time to carry out his work. Nothing was rushed & he was very professional & courteous with my elderly father. Both my father & I were extremely happy with the service & would highly recommend this company.
Sujata Paul, 27 June 2025 Lower Edmonton, Greater London engineer: Grant Corney
Exceptional service provided by ADI
All of the interaction we had with ADI, from the initial phone booking process with Christian to the engineer visit from Darren was excellent. Darren was prompt to visit the property and assess the situation making sure all avenues of investigation and leak detection were carried out calmly and professionally. He kept us informed of his progress at all stages of the investigation and subsequent fix that was put into place. And he properly cleaned up after himself too which was much appreciated. Thoroughly recommend ADI and would not hesitate to use their services again
Janine, 26 March 2025 Hampton, Greater London engineer: Darren Smith
Kristof was great
Kristof was great, identified the problem on my ground floor which wasn't easy to find, fixed it, re-fitted the floor impeccably. Not cheap but better to use these guys than some of the other options who waste time and bill by the hour etc. The customer service rep was also very good. Clear comms.
Stephen Roberts, 12 February 2026 Winchmore Hill, Greater London engineer: Krzysztof Kobylinski
James was very friendly and extremely competent handling many gadgets very professionally. He spoke to Thames Water who promised him they would deal with this within four hours and we did not need a stopcock and they agreed. He confirmed it is their meter problem and whilst TW did visit within 4 hours, we await the work by them to stop the leak. We are hopeful - James has made it possible to get this long running problem sorted . Thank you
John Sutcliffe, 15 August 2025 Vauxhall, Greater London engineer: James Bexter, James Hunter
Fastastic work
Darren was excellent at finding the leak in my property. Communication about the planning and work was great He explained all the steps and was very efficient and cleaned up afterwards. I would have no hesitation in using this company again.

The Barron of ADI Leakdetection
Contacted ADI Tuesday Engineer arrived Wednesday morning earlier than expected first time that's happened to me. Matthew Barron what a man professional, friendly, enthusiastic, he immediately got to work systematically detecting a small but important leak in a concrete floor and resolved it very quickly. Vantastic informative and trouble free. I would recommend Matthew as the man to go to for your hidden leaks. Thank you Matthew.
J CHAPMAN, 15 May 2024 Swanpool, Lincolnshire engineer: Matthew Barron
Great job done!
The plumber/expert (Scott) turned up exactly when I was told he would arrive. Very polite and professional about his work. Fully explained everything and clearly showed care and consideration throughout the work he carried out. Many thanks Scott for taking such good care and time and trouble over everything. The job was completed and am a completely satisfied customer. Thanks Scott!
Carolyn Dewhirst, 9 July 2025 Earlesfield, Lincolnshire engineer: Scott Hardcastle
Very helful, & friendly
We were expecting an engineer 6/1/26, but received a phone call 2/1/26 saying they had a cancellation. Robert arrived on time, quickly found the leak, & fixed the problem. He answered all our questions, we found the whole experience positive, Would definatley recommed the company
Karen Pearman, 4 January 2026 West Stockwith, Nottinghamshire engineer: Robert Gires
ADI responded to our call out in quick time, once Robert arrived the leak was found quite quickly, the leak was a plastic pipe which had burst under a stone floor and there would have been no way of detecting this without the specialist equipment, the floor was excavated and the pipe repaired, the service was excellent and a big shout out to Robert who certainly knew his stuff, Robert was friendly, pleasant and professional, thank you
Adrian Archer, 19 March 2025 Thurgarton, Nottinghamshire engineer: Robert Gires
Easy to deal with great customer experience

Mark Stafford, 18 June 2025 Thurcaston, Leicestershire engineer: Scott Hardcastle
Hi this water leak was in Sheffield and Robert from ADI arrived on time. Very polite and informative and took us through every stage of what he was doing. In the end the water leak was located outside and by using his sensors and water leak equipment was able to trace the leak within a metre. Robert began to dig located the leak and repaired the pipe. Excellent job by Robert, this leak was at my mother’s house who is 90 years of age so was really relieved when the leak was found. As the leak was on mother’s property the water board didn’t want to know. Well done Robert and ADI.
Shaun Hughes, 30 January 2025 Jordanthorpe, South Yorkshire engineer: Robert Gires
Matthew was excellent
Matthew arrived early and transferred a large amount of equipment to the house. He was very thorough in his attempt to trace where the water loss was.He explained what he was doing during the whole process including sound detection and gas / pressure checks. By a process of elimination he finally traced the loss to the toilet cistern. Brilliant work. Not cheap but worth it! My usual plumber had been unable to find the problem and had suggested getting someone with additional equipment as above. Glad I did.
Mr Unwin, 1 March 2024 Horsforth, West Yorkshire engineer: Matthew Barron
Outstanding service
Outstanding service. If only all companies were as professional! A special shout out for Matthew who was amazing. Not only was he diligent and friendly, he explained the process and found the leak on my drive with careful, meticulous investigation using scientific tools and equipment. He also did a fantastic job minimising damage to my new drive. A definite 5 stars. Would highly recommend.
A Lombardi, 27 February 2026 Lindley, West Yorkshire engineer: Matthew Barron
Central Heating Leak
Brett kept us informed and updated as he worked through the house using different methods to locate the leak. After carefully and methodically identifying the location he used 3 alternative methods to verify that it was the location. Very thorough, tidy, knowledgeable and helpful. Would highly recommend.
Warwick Oliver, 8 October 2024 Scotton, North Yorkshire engineer: Brett Steele
Excellent service
Matthew was fabulous. Located a very difficult to access leak and repaired it for me. I can’t thank him enough. He worked extremely hard and cleared away everything afterwards. So relieved I used this company. Also, my dog loved him - which was a bonus.
amanda james, 24 February 2026 Tang Hall, North Yorkshire engineer: Matthew Barron
Hamaad came round to look into a leak we’ve had in our flat for some time and unable to source. He managed to source leak with the flat above quickly and advise flat above on how to resolve. We are confident in our own flat now knowing where the leak is from and very happy with Hamaad’s service. Very clear and gave great advice.
Mr Luke Baker, 21 July 2025 Partick, Lanarkshire engineer: Hamaad Janjua
ADI found my leak
I made a telephone call to ADI who were helpful and gave me a quick appointment. The engineer, Hamaad, was knowledgeable, explained what he was going to do to find my leak and let me follow his testing. He found it, repaired it and tidied up. Tested to make sure everything was back to normal. He was polite and friendly.
Hilary Fraser, 8 February 2025 Lenzie, Dunbartonshire engineer: Hamaad Janjua
Hamaad was fantastic
Hamaad was brilliant the minute he walked in. He knew exactly what he is doing. He explained everything clearly, he also gave me a lot of advice. He was on time, responsible, respectful and well experienced! Now I can safely go on to do my next step! Thanks again Hamaad! Take care
Rocky Leung, 28 February 2025 Muirhouse, Midlothian engineer: Hamaad Janjua

Excellent service
Excellent service. Elusive water leak was found underground with your specialised equipment and then repaired. Robert Gires, your technician was superb. He was on time, polite, considerate and professional and he worked all day from 9.30 until 5.00 until he had resolved the issue. If there are bonuses going he deserves one!
David Webber, 8 May 2024 Leckhampton, Gloucestershire engineer: Robert Gires
Highly recommend ADI and Mark!
Had a great experience with ADI, from the initial call with Monique to our engineer Mark Pavitt. Both were super accommodating and friendly. Mark is clearly really experienced and was able to locate and fix the leak in the day. I’d really recommend using them if you’re looking for help with a potential leak.
Sophie, 26 January 2024 Trusham, Devon engineer: Mark Jones, Mark Pavitt
James arrived ahead of time a very likeable guy.He got on with the work well, and updated me every hour or so.He knew the leak was under slabs or crazy paving adjoining.However,because plastic insulation was placed below the slabs and also an inch of concrete, it was difficult to detect the exact spot. After digging up a small crazy paving area which proved negative,he then removed 2 big slabs dug down and there was the problem.He then mended the leaking pipe ,tested it and finished the job. I thought he was brilliant at his job.

James Bexter at ADI Leak Detection did a great job tracing a small hidden leak that had caused major damage. James explained everything clearly and was extremely helpful, as were the staff I contacted to book the appointment. Would definitely recommend.

Multiple leaks found and fixed
Gabor worked hard across a long day and (hopefully) found and fixed all our leaks. He was professional, polite and patient.

I would definitely recommend ADI. Very professional on the phone they explain what the engineer would do on site.

Excellent service
From first contact to final receipt of invoice and report, they have been very professional and extremely helpful. The engineer that attended (Gabor) was very thorough and explained every step he was undertaking to resolve the issue. His persistence was of the highest level and resulted in a positive identification of the issue which he fixed straight away.
All the staff of ADI are very nice and helpful. They booked the earliest time for the leaking detection. The engineer, Gabor is very nice, professional and efficient. I'm so glad to have their service and it's really the best choice. Highly recommended.

Paul was amazing
Paul was amazing! Found the leak straight away but verified it was where he thought it was! Dug up the block paving straight to the pipe and found a leaking joint. Fixed it straight away and 3 hours later we were sorted!

We have just had Hammad out and he was fantastic. He rang me yesterday to confirm the booking and arrived right on time. He was very professional. He was also very friendly and easy to talk to. He managed to locate our leak which was under the concrete in our kitchen floor. He told me right throughout what he was doing and why. He fixed the leak and did a very thorough job. He cleaned up after he was done and I can't recommend him enough. I would be happy for him to do jobs in my house again any time.

A friendly and professional service. We got someone out to us very quickly - Robert was great, he identified the problem and had a number of recommendations to improve other aspects of the heating and plumbing, including suggestions which could save us money in the long run.

Paul, the engineer turned up on time, was friendly, knowledgeable, and listened patiently while I explained the problem. After carrying out his investigations he explained everything to me clearly and in a way I could understand. I wouldn’t hesitate in recommending him or this company to others.
