They were on time and did a great job

They were on time and did a great job! Three other leak detection companies couldn't find the leak.
These guys found it and fixed.
I believe because they are a small business, each customer is more important to them, they might not have a fash call centre but you don't pay for the call centre either and when you call you speck to the owner directly.

The technician was focused, experienced, and communicated really well throughout the whole process. I'm very happy with the outcome, price and service and I strongly recommend them.

Really impressed with 247 Leak Detection. I had a particularly difficult and stressful leak to find and the guy who came out was absolutely lovely — really friendly, professional and worked so hard to try and find the source. He was very thorough and produced a detailed report there and then, which was incredibly helpful.

He explained everything clearly and I really appreciated how much effort he put into helping me. I wouldn’t hesitate to recommend 247 — excellent service from start to finish.

Over 1.5hrs late with no communication!

The appointment was for 4pm but the engineer never turned up until after 5:30pm without any communication. I called the landline several times but no one picked up and tried the mobile which went to voicemail and I couldn't leave a message as the mailbox was full. When I made the appointment the previous day, the person in the office didn't call back when she said she would so I had to call back twice but she said she wouldn't hear back from the engineer to confirm for another 4hrs from the initial call.

Ali arrived at my home, got out of his van and identified my leak in under 10min.
He is honest and knowledgeable in his field and I would highly recommend him to family and friends.

This leak had been a problem for over a year, Thames Water has been charging us for our excess water usage.
We had a local plumber in NO JOY
British Gas also made a visit because we thought it was a boiler problem NO JOY

Before Ali arrives you receive a breakdown of his fee’s. He located the leak and fixed it within record time.
We did not have to flush our system before his arrival.
I felt safe and in good hands from start to finish.

Hidden leak resolved by Moe

Moe was a true professional and managed to resolve my hidden leak by using his ‘track & trace’ service. He was always contactable and very responsive to questions that l had prior to visiting my home. I would highly recommend him and would definitely use him in the future if need be, thanks Moe you’re a star.

Kay helped secure an appointment same-day and was quick to respond to calls throughout the day. And I was so happy to have Ali attend because I had read so many positive reviews already. Ali and his apprentice were clear with communication and effective with time. It’s evident Ali is very knowledgable about leaks.

Top-notch service from start to finish

Top-notch service from start to finish. Ali was incredibly professional and did a high quality work. They were honest about the repairs needed and didn't try to upsell me on anything unnecessary. It's a relief to have a plumber I can trust!"

“I called this company because they said they always find the leak…

“I called this company because they claimed on the phone that they always manage to find leaks. Unfortunately, they could not locate the leak in my property, yet they still charged me £425. They even told me that many people don’t pay them and insisted I pay immediately, which felt very distrustful– I now understand why. Overall, poor service, misleading information from the office, and lack of professionalism, and an uncomfortable experience. I would not recommend this company.”

Réponse de 247 Leak Detection London Ltd

Thank you for your review. However, we must clarify that all the statements made here are misleading and do not reflect the actual events during the visit.

You contacted us stating that your boiler was losing pressure and you had been told there may be a leak on your central heating system. During our phone conversation we clearly explained that if a leak exists, we use advanced leak detection methods — including tracer gas — to accurately locate it.

Upon attending the property, our engineer first carried out a central heating pressure test, which is the standard diagnostic procedure. This test is 100% reliable in determining whether a leak is present. In your case, the system held pressure with no drop, which confirmed there was no leak within the central heating system.

Despite this result, we went further and carried out tracer gas leak detection across the property — an advanced, non-invasive method used by specialist leak detection companies. The results again confirmed there was no water leak within the property.

When we asked who had advised you that there was a leak, you explained that a local plumber had looked at your boiler. As advised on site, boilers should only be inspected and diagnosed by a Gas Safe certified engineer, not a general plumber.

Our engineer Ali also explained that the issue appeared to be related to the boiler itself (likely the expansion vessel or heat exchanger) rather than a pipe leak. At the time of the visit you were polite, acknowledged this explanation, and even asked us for a quotation to repair the boiler issue.

Regarding payment, our company policy is clearly stated: payment is required once the diagnostic work is completed before the engineer leaves the property. Unfortunately payment was not made on the day and was only received 8 days later.

Finally, the comments made about our engineer Ali are extremely surprising. Ali has worked with us for many years and has received consistent praise across numerous reviews for his professionalism, respect, and expertise. This is the first complaint we have ever received regarding his conduct.

Our investigation was completed using professional leak detection procedures, and the findings were clear: there was no leak within the property; the issue was related to the boiler itself.

We always aim to provide honest, accurate leak detection services using advanced equipment, and we stand by the results of the investigation carried out at your property that there is no leak which you should be happy about.

Ali was our leak engineer who came to check for a leak in the house. Our water bill was doubled over and we were told it could be a leak. He came and found a silent leak on the toilets. He was professional, knowledgeable and changed our toilets with the help of Has, his apprentice, lovely guy too. They treated our house and the work with respect and care. We couldn’t be happier with such a professional plumber/ leak detection specialist like Ali.

Wet patch on ceiling below bathroom

We recently discovered a wet patch on our ceiling directly below the upstairs bathroom, so we contacted 247 Leak Detection. They were able to attend the very next day, which was incredibly reassuring. Their team quickly identified the source of the leak and clearly explained the issue, offering several options to resolve the problem.

Once we agreed on the best approach, the necessary replacement parts were sourced promptly and the repair work began. The engineer, Ali, with assistance from Salman, carried out the work efficiently and professionally. This involved replacing the bathroom sink taps along with sections of the water and waste pipework.

During the job, Salman also highlighted that the pipework connected to the bath and bidet was showing signs of corrosion. He recommended replacing these at the same time to prevent a potential future leak, which we appreciated as proactive and honest advice.

The entire job was completed in just over three hours, with minimal mess left behind. The service was professional from start to finish and the team were friendly, knowledgeable, and efficient. I would definitely recommend 247 Leak Detection to anyone needing a reliable and thorough leak detection and repair service. 👍

Saleh, a true gem in the trade

We had 2 other companies over to find the reason of damp patches on our wall and none couldn’t help. It was stressful but everything changed when Saleh was dispatched to us as the leak detection engineer. His expertise was truly outstanding & beyond anything we expected. He carefully and methodically investigate until he precisely identified the source. What really sets Saleh apart is that his knowledge goes far beyond leak detection and plumbing as he truly understands structures of a building in a way that gives you complete confidence.

We are so grateful for his honest advice and help. We wouldn’t hesitate to recommend him without a doubt, definitely a true gem in the trade.

Brilliant

I contacted these Leak Specialists, they sent a senior member of the team to my clients home! Ali was amazing, my client described him as easy to communicate with and efficient. I will be adding them to my black book! They solved the problem, turns out it was the boiler at fault and they’re coming back to help out with this too
