Central Heating Systems Leak Detection Service

Central heating leak detection is the non-destructive process of finding leaks in central heating systems.

Our central heating leak detection specialists are experts at leaks in your heating system under your floor, in the ceiling or wall using non-destructive technologies including:

  • Thermal imaging camera to locate hot heating pipes in walls, floors and ceilings.
  • Tracer gas to identify the exact location of leak on heating systems.
  • Heating leaks are detected using Acoustic listening devices to listen for the sound of escaping water.
  • Moisture Meters to measure moisture levels in building materials close to radiators and heating pipework.
  • Borescope Inspection Cameras to look inside hard to reach cavities
  • Pressure Testing to confirm there are no further leaks.

ADI Leak Detection are proud to be CIPHE, WIAPS & Watersafe accredited heating leak detection specialists with over 700 5* Trustpilot reviews!

Our Non-Invasive Methods For Detecting Heating Leaks

Non invasive non-destructive central heating leak detection methods help to locate water leaks without causing damage to your property.

Our central heating leak detection specialists carry a wide range of non-invasive leak detection equipment on board including thermal imaging cameras, tracer gas testing equipment, acoustic listening devices, damp meters and years of knowledge & experience!

This specialist equipment, coupled with our detailed investigation process allows us to detect the source of water leaks under carpets or any other floor coverings with minimal disruption.

MethodBenefits & Method 

Thermal Imaging Cameras


  • Thermal imaging is used to trace hot water piping in walls, floors and in cavities.
  • Hot water leaking from pipework shows as a temperature variation
  • Thermal imagery gives clear evidence of damp areas
  • Thermal Imaging is used to check all heating pipes throughout the property for leaks.

Tracer Gases

  • Hydrogen / Nitrogen Tracer-gas (95% Hydrogen /5% Nitrogen) safely and effectively identify the location of leaks in central heating systems.
  • Central heating pipes are pressurised with tracer gas.
  • Tracer gas escapes from the leak location and rises to the surface.
  • The hydrogen in the tracer gas is detected using tracer gas sniffers.
  • Tracer gas is detected where the system is leaking.

Acoustic Leak Detectors

  • Acoustic listening devices otherwise known as ground microphones, listening sticks or listening discs amplify sounds under the floor, in walls or cavities.
  • Acoustics leak detection is used to listen for the sound of escaping water.
  • Acoustic listening devices can be used to listen for the sound of escaping tracer gases
  • Acoustic leak detection equipment helps verify the heating leak location identified by another method.

Moisture Meters

replacing equipment type with Moisture Meters

  • Moisture meters are used to locate damp in walls and floors.
  • A damp meter can be used to plot moisture, leading to the source of damp.
  • Pin-type, Pinless and Infrared moisture meters can be used to trace damp from heating leaks.

Borescope Inspection Cameras

  • Borescope cameras (Inspection CCTV Cameras)  are used to look for heating leaks in ceilings, under floorboards, behind cupboards and in other voids.

Pressure Testing

replacing equipment type with Pressure Testing

  • Pressure testing is used to confirm if a central heating system is leaking or holding pressure.
  • Gas is inserted into the system and pressurized. if the pressure drops then the system has a leak. A leak is not present if the system holds pressure.
  • A pressure test on central heating pipes is often used to confirm a successful leak repair.

Central Heating Leak FAQ’s

Yes, we will need you top top up the boiler pressure, turn your heating on and the thermostat / thermostats to max around 1 hour before our arrival.

This will ensure your heating plumbing pipes are at the maximum temperature, making the heat energy traceable using thermal imaging. This ensures efficiency in our process helping to ensure a successful trace and access.

The fixed-price leak detection cost depends on the type of property and suspected source of the leak.

The price is usually less to locate a leak in a domestic property than in a commercial building.

If you have trace and access cover on your home insurance policy then our you should be able to claim back our “trace and access” costs.

Trace and access does not cover the costs of repairs or replacements for central heating leak problems; however, they will cover the costs of locating water leaks on your property.

Most insurance companies will cover eligible expenses, like accidental damage to infrastructure or furniture.

If you’re unsure of your coverage, contact your insurance company to find out more and get repair cost clarity.

Central heating leak sealer is a temporary solution for repairing heating leaks.

A leak sealer has limited effectiveness as it usually masks the true problem and doesn’t address the underlying cause of central heating leaks.

Professional expertise is recommended for significant leaks and lasting solutions, as not all heating systems are compatible with leak sealers.

There are some visual inspections that a homeowner can carry out in an attempt to find a heating leak before calling us.
