Commercial Heating System Fault Diagnosis
Commercial heating issues are rarely obvious. This fault diagnosis service is a structured on-site investigation to identify the root cause of breakdowns, poor performance or intermittent heating, so you can make the right repair decision and get the system back to safe, reliable operation.
More information
What commercial heating fault diagnosis covers
A focused diagnostic visit designed to find the fault, explain it clearly, and set out the practical next steps.
- Initial system assessment and safety checks (gas, water pressure, electrics and controls as applicable)
- Fault finding on boilers, plant and distribution (pumps, valves, pipework and emitters)
- Control and temperature investigation (timers, thermostats, zone controls, sensors and wiring)
- Checks for common causes of lockouts, loss of heat, poor circulation and noisy operation
- Evidence-led conclusions, not guesswork
- Clear recommendations for repair, parts, or further specialist testing if required
When this service is the right fit
Book fault diagnosis if your site has any of the following:
- No heating or hot water, or recurring boiler lockouts
- Cold spots, uneven heating, slow warm-up or poor heat output
- Pressure loss, frequent topping up, or signs of leaks
- Unusual noises from plant, pumps or pipework
- Controls not responding, heating running at the wrong times, or zones not working
- Repeated call-outs without a lasting fix
How the diagnosis is carried out
The visit starts with questions about symptoms, recent changes, and any previous repairs. Testing then follows a logical sequence, typically moving from obvious faults to component checks and control verification.
Where possible, you will be shown what has been found and why it matters. If the issue needs parts, access permissions, or further intrusive investigation, you will receive a clear plan and options before work continues.
What happens after diagnosis
You will get a plain-English summary of findings and recommended actions. If repairs are needed, you can expect a prioritised scope (urgent versus planned), likely timescales, and any compliance or safety considerations relevant to commercial heating systems.
If you prefer ongoing assurance, diagnosis can feed into a planned maintenance approach to reduce repeat faults and unplanned downtime.
