Moe’s knowledge and expertise was brilliant. He was able to quickly detect a leak that home insurance had been unable to find for a year. Home insurance had given false information on the source of the leak, but Moe worked around this and found the true source and resolved it same day with super helpful advice about what to do with remedial works and home insurance next steps. 10/10 would recommend for no fuss leak detection.Posted on Google

If You Have A Question About A Leak We Would Love To Help
Find Out The Answers To Some Of Our Most Commonly Asked Questions
Exceptional and competitive leak detection services designed to identify leak sources efficiently and effectively. A precise service with reputable leak detection experts.
How much does leak detection cost in London?
Leak detection costs in London can vary depending on the type of leak, the size of the property, and the equipment required to locate the issue. Most professional leak detection services typically start from £450+, with more complex commercial or underground investigations costing more.
At Leak Detection 24/7, we use non-invasive technology such as thermal imaging, acoustic listening devices, tracer gas, and moisture mapping to locate leaks quickly and accurately, helping reduce unnecessary damage and repair costs.
How do you find hidden water leaks in London properties?
Hidden water leaks are usually detected using specialist non-invasive equipment designed to locate leaks behind walls, under floors, underground, or within central heating systems. Common methods include thermal imaging cameras, acoustic leak detection, tracer gas technology, pressure testing, and moisture meters.
These advanced techniques allow our engineers to pinpoint the exact source of the leak with minimal disruption to your property.
Can London plumbers detect hidden leaks?
While many plumbers can identify visible plumbing problems, hidden leaks often require specialist leak detection equipment and expertise. Leak detection specialists use advanced diagnostic technology to trace concealed leaks without unnecessary excavation or property damage.
In many cases, plumbers will call in a dedicated leak detection company when a leak cannot be found through standard plumbing methods alone.
Do insurance companies cover leak detection in London?
Many home insurance policies in the UK will cover the cost of professional leak detection under “trace and access” cover, particularly when the leak has caused damage to the property.
Coverage can vary depending on your insurer and policy terms, so it is always recommended to check directly with your provider. We can provide detailed reports, photographs, and supporting documentation to assist with insurance claims where required.
How quickly can you attend a property in London?
We offer fast-response leak detection services across London and surrounding areas, including emergency callouts where required.
In many cases, we can attend the same day or within 24 hours depending on availability and location. Our engineers cover all Greater London boroughs and are equipped to handle residential, commercial, and emergency leak detection appointments.
