Does Your Central Heating System Have a Leak?
If your boiler frequently loses pressure or requires constant top-ups, you may have a central heating leak — and early detection is essential to prevent costly damage.
Central heating systems rely on pressurised hot water to distribute heat evenly throughout your home. When a leak develops — even a minor one — it can cause significant damage to floors, walls, and structural elements if left undetected.
Water leaks are a common cause of pressure drops, and detecting them early can prevent far more extensive and expensive repairs. Our experienced loss assessors work alongside specialist leak detection experts to accurately locate the source and ensure your insurer is held to account for the full cost of repairs.
How We Repair a Central Heating Leak
We use non-invasive, specialist techniques to accurately locate and repair central heating leaks — minimising disruption to your home and daily routine.
Thermal imaging allows our specialists to pinpoint leak locations without lifting floors or cutting walls unnecessarily.
Thermal Imaging
Using advanced thermal imaging cameras, our specialists detect temperature variations caused by escaping hot water beneath floors and behind walls — without any destructive investigation.
Acoustic Testing
Highly sensitive acoustic equipment listens for the subtle sound of water escaping from pressurised pipework, allowing our experts to pinpoint the exact leak location with minimal disruption.
Tracer Gas Detection
A safe mixture of hydrogen and nitrogen gas is introduced into the pipework. As the gas escapes through the leak point, specialist detectors above ground identify its precise location.
Moisture Mapping
Our surveyors use moisture meters and damp detection equipment to trace the spread of water damage through walls, floors and ceilings — ensuring a full scope of damage is captured for your insurance claim.
Signs Your Central Heating System May Have a Leak
Many central heating leaks go unnoticed for weeks or even months. Knowing the warning signs early can save you thousands in repair costs and prevent serious structural damage to your property.
Dropping Boiler Pressure
If your boiler pressure gauge regularly drops below 1 bar and requires frequent topping up, a leak in the system is the most likely cause.
Damp Patches on Walls or Floors
Unexplained damp spots, staining, or discolouration on walls, ceilings, or floors can indicate water escaping from concealed pipework.
Cold Spots on Radiators
A leak in the system can cause air pockets and pressure imbalances, resulting in radiators that fail to heat evenly or at all.
Lifting or Buckling Floors
Water escaping from underfloor pipework can cause timber floors to warp, lift, or buckle — often a tell-tale sign of an ongoing leak beneath the surface.
Peeling Paint or Wallpaper
Moisture seeping through walls causes paint to bubble and wallpaper to peel away from the surface, even when the area does not feel visibly wet.
Unexplained Rise in Bills
A sudden or unexplained increase in your energy or water bills can indicate your heating system is working harder to compensate for lost pressure due to a leak.
