Leak Detection on Central Heating Systems

Do You Need Help With a Central Heating Leak?


We offer accurate leak detection on central heating systems. Central heating leaks usually show up around September, after months of non-use.  We switch our central heating system on in the Autumn only to find it’s not working, boiler faults, loss of pressure and leaking pipes. This is when we realise just how much we need and use our central heating.

In many cases a heating engineer will confirm that it’s not the boiler at fault and will suggest you have a leak on the heating pipe system.

Further investigation now becomes more difficult, with pipes hidden under floors and behind walls. It’s at this point you should consider a central heating leak detection specialist.

Most insurance policies have ‘trace & access’ cover.

This means your insurers should cover any costs incurred for leak detection on your central heating leaks.

Once we have found your leak we will produce a professional report which will more than meet your insurers requirements to allow them to make a decision to pay out.

If you have any problems with this then we are happy to talk to your insurers to help clarify any issues around what we have done or seen.

Frequently Asked Questions

How do I find a leak in my Central Heating System?

This depends largely on the layout of your heating system, size / shape of your home or property, and the build of your home or property. A typical heating system is made up of 3 key parts: the boiler, the radiators and the pipework connecting them. In most cases, each room in the property contains radiators and pipework, with pipework often being underfloor and inside/on the walls.

You can narrow the location down to some degree by understanding where in the system radiators start to lose pressure, or don’t heat. Whether you can then access and fix that leak depends on the factors above.

What if the heating leak is under floor? Can it be found and fixed?

In short, yes. Whether you can do that without the help of a central heating specialists depends on access, confidence and risk you’re prepared to take. Certain floor types, such as concrete floors or tiled floors, make access to underfloor piping more difficult. Our Tracer Gas and Acoustic Correlator equipment is designed to allow detection of the leak location without access.

My central heating is losing pressure, does that mean I have a leak?

Not in all cases, no. If you are constantly having to top up the pressure then there is a chance you have either a leak on your central heating system OR a fault on the boiler. We would always recommend you get your boiler inspected first, in our experience around 40% of our calls to leaks on central heating systems are not in fact water leaks but faults on the boiler.

What’s the cost of central heating leak repair?

There is no fixed overall price. The costing of detecting the leak on the central heating system is often easier because of the state-of-the-art equipment we use. There’s little intrusion or requirement to pull up floors etc. Ultimately though we need to come out and see the scenario to quote effectively. The cost of repair is largely dependant on the damage caused by the leak and the access available. Some of the cost can be covered under insurance. Find out more.
