Boiler Losing Pressure?

If your boiler pressure keeps dropping without reason, it could indicate a hidden central heating leak. Left unresolved, this can leave you without heating or hot water - frustrating at best, and a real risk to your comfort in colder months.

A pressure drop often means water is escaping somewhere within the system. Because most heating pipes are hidden beneath floors or behind walls, the leak isn’t always visible. Recognising the early signs helps prevent costly damage and disruption.

Common signs include:

Frequent need to top up boiler pressure
Cold spots on radiators or uneven heating
Persistent damp patches on floors or skirting boards
Strange noises coming from pipes or your boiler
Rising energy bills due to inefficient heating

If your boiler pressure keeps dropping without reason, it could indicate a hidden leak in your heating system. Our central heating leak detection process identifies the source without unnecessary disruption.

How We Find Central Heating Leaks

Finding a hidden central heating leak requires precision and the right tools. Specialist engineers use proven non-invasive methods to locate leaks quickly and accurately. Disruption to your home stays low.

Gas Tracing Technology

A safe, non-toxic tracer gas is pressurised through the heating system to pinpoint leaks with accuracy. The technique works on most systems, including underfloor heating, combi boilers and megaflow tanks. Even small leaks can be identified beneath concrete or flooring.

The Process

The heating system is safely isolated and prepared
Tracer gas is introduced and circulated through the pipework
Any escaping gas pinpoints the exact leak location
Findings are recorded in a clear report to support an insurance claim

These technologies are equally effective for residential leak investigations, where precision and minimal disruption are essential during trace and access works.

This approach keeps disruption low, delivers accurate results, and provides clear evidence for your records.

Our Team

Our people are at the heart of everything we do. Once a trusted specialist engineer has located your leak, dealing with the aftermath of water damage can be your biggest challenge. From the very start, you’ll be supported by a dedicated surveyor who coordinates damage assessment, meets with the insurer’s loss adjuster, and oversees approved repairs through our trusted contractor network.

You’ll also have a dedicated claims manager who liaises with your insurer to present your claim, agree approved works, and ensure a fair outcome and a smooth, stress-free process from start to finish.

Super Service

I am an overseas landlord. My tenant’s ceiling collapsed from a bath-mixer leak. APC ran the claim, arranged drying and full restoration, and managed it all while keeping me informed remotely. Couldn’t have done it without them.

Leak Found

Great company to know in a time of difficulty. When no one else could find the leak, they manage to find it in less than three hours.

Excellent

The sudden appearance of ceiling stains was stressful. Leak traces identified the leak and produced a detailed report so the leak could be exposed and repaired. Then their claims team at allpropertyclaims worked with my insurer to approve and cover drying and reinstatement. The whole thing cost me nothing, and my home was back to normal quickly.

Extremely happy with leak tracers! And only wish I had found them sooner. They helped me find an impossible leak. I had first contacted 2 plumbers who tried to find the leak but were not able to. Having wasted money on these plumbers I was advised by my insurer to get a specialist leak detection company.

Indeed, Tan and the team assured supreme service, professionalism, guidance and support at every stage of my claim and that is exactly what they delivered

Following the failure of three different plumbers to locate a leak in my bathroom, I made contact with Moez who arranged for an expert to visit my property with specialist detection equipment. The source of the leak was quickly found and a temporary repair effected which required the bathroom floor to be partially  

Frequently Asked Questions

We know insurance claims can feel overwhelming, especially if it’s your first time dealing with one. That’s why we’ve put together this FAQ section - to answer common questions, explain the process in plain English, and show how our expertise makes the journey smoother and less stressful for you.

Do central heating leak sealers work?

Central heating leak sealers can temporarily stop small weeps but are not a permanent fix. They often fail over time and can cause blockages or void warranties. It is better to always properly locate and repair the leak for a lasting solution.

How do I find a hidden leak in my central heating system?

To find central hearing leaks, check visible joints, valves and radiators for damp spots, then monitor pressure drops. If the leak is hidden under floors or walls, use a professional leak detection with tracer gas or thermal imaging for precise, non-invasive location.

What if the leak is buried under my floor or behind a wall?

Leak detection technology will help pin point where the leak is but to get to the leak and stop it, you will have to undertake intrusive access. As property owner it is your duty to mitigate damage and your insurers will expect to see you have done so before they agree to a claim.

Case Studies

Our case studies show how we’ve helped property owners detect and resolve hidden leaks. From damp walls to unexplained water damage, we use advanced, non-destructive methods to locate the source quickly and restore peace of mind.

Central Heating Pipe

Incident

The client, who lived in a ground floor flat, noticed her boiler pressure dropping to zero within 30–60 minutes after topping up. As a result, she had no heating or hot water. Some damp was visible in an understairs cupboard but nothing else. A specialist leak detection engineer advised that the leak was likely in a central heating pipe and that gas tracing would help pinpoint the location.

A leak detection survey was arranged for the client, for which she paid directly. As her home insurance policy included trace and access cover, she was advised that this cost should be refundable once the insurance claim was approved.

Client Concerns

As the suspected leak position was at the entrance to her kitchen, the client was concerned that the area might need to be dug up. She was worried she might not be able to use her kitchen for several weeks and could need to move out of the property, leading to additional inconvenience and costs.

She was also concerned about visible damage to her neighbour’s wall decorations and complaints she was receiving from next door.

Finding the Leak and dealing with the Insurance Claim

The appointed leak detection specialist carried out the intrusive access works, carefully exposing the section of floor where the gas tracing had pinpointed the leak.

Following the survey, the client instructed Allpropertyclaims Ltd (APC) to manage her insurance claim. The APC team promptly assessed the damage within the client’s property and her neighbour’s, arranged for drying equipment to be installed to prevent further damage, and prepared a detailed report for the insurer.

APC then met with the insurer’s loss adjuster on site to agree the costs of reinstatement and restoration to return the property to its pre-loss condition. They also secured insurer-funded accommodation for the client for the duration of the repair works.

As the building was covered under a block insurance policy, APC coordinated the neighbour’s claim under the same policy, ensuring all costs were settled by the insurer. Both the client and her neighbour were very happy with the outcome.
