FREQUENTLY ASKED QUESTIONS
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.
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.
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.
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.
