Typical Leak Detection Costs in London
Guide prices for our most common services. We always confirm the exact figure before starting work.
All prices include VAT. Final cost depends on property size, access requirements, and complexity. The exact figure is always agreed before work starts.
What Is Included in Every Survey
Every leak detection survey from Leak Detect London includes a comprehensive written report with thermal images, photographs, and a clear description of the leak location and recommended repair. This report is designed to be insurance-ready for trace and access claims.
Our engineers use non-invasive methods wherever possible, including thermal imaging cameras, acoustic listening equipment, tracer gas systems, and professional moisture meters. We only recommend opening up a property when absolutely necessary, and we always explain why before proceeding.
There are no hidden charges. The price quoted includes the engineer visit, all equipment used, and the written report. If additional work is needed beyond the original scope, we will explain the situation and provide a new quote before proceeding.
Leak Detection Cost Questions
How much does leak detection cost in London?
A standard thermal imaging or acoustic survey starts at £150. A combined survey using several methods is £250 to £500, and an underground supply pipe trace is £300 to £500. The figure is agreed before the engineer travels and does not change on the day. Every price on this page includes the visit, the equipment and the written report.
How much does central heating leak detection cost?
Central heating leak detection starts at £150 and most heating surveys fall between £150 and £300, depending on how much of the circuit has to be isolated and tested. A system with buried pipework under a solid floor takes longer than one with accessible runs, which is the main thing that moves the figure.
Do you charge if you cannot find the leak?
Not if the leak is on your own property and we cannot find it: that is what no find, no fee means, and the detection fee is not charged. It does not stretch to leaks that turn out to start elsewhere. If the survey shows the water is coming from a neighbouring property, a shared riser or the mains in the road, the visit is payable, because it has given you the evidence of whose repair it is. Nor does it cover a survey that finds nothing is leaking at all: where the pressure loss turns out to be the expansion vessel, or the damp turns out to be condensation, the hours are charged, because ruling a leak out is the answer and not the lack of one.
Is there a call-out fee on top of the price?
No. The price quoted is the price for the survey, including the engineer attending, all equipment used on the day and the written report afterwards. If work beyond the original scope turns out to be needed, you get a new figure before anything else is done.
What makes one leak survey more expensive than another?
Three things, roughly in this order. How many systems have to be isolated and tested separately, because ruling the heating in or out is a different job from testing one bathroom. Whether the pipework is accessible or buried under screed or a driveway. And how large the property is, since a long supply run takes longer to correlate than a short one.
Is cheap leak detection worth it?
It depends what is being left out. A visit priced below the cost of running the equipment usually means one method rather than several, and a single method that cannot reach your leak produces an inconclusive visit you still pay for. Ask which methods are included and what happens if the first one does not find it, rather than comparing headline figures alone.
Can I claim the cost back on my insurance?
Often, through the trace and access section of a buildings policy, which pays the reasonable cost of finding an escape of water and opening up to reach it. It is subject to its own limit shown in your schedule, and it normally responds only where the cause is escape of water rather than wear or a failed seal. Check your policy wording before you rely on it.
