One of the most common causes of commercial boiler breakdown. Our engineers diagnose whether it’s the ignition electrode, the gas valve, the PCB, or something else, and carry out the repair with minimal delay.

Loss of pressure or a failing circulation pump can prevent a commercial boiler from operating correctly. We restore pressure, replace faulty pumps, and check the wider system to prevent the problem from recurring.
A cracked or fouled heat exchanger is a serious fault that affects both efficiency and safety. We conduct thorough inspections and provide honest advice on whether repair or replacement is the more cost-effective option.
Sophisticated electronics control modern commercial boilers. When a PCB or control board fails, the boiler simply won’t function. We diagnose electronic faults quickly and source replacement parts from our extensive supplier network.
Any fault affecting the flue or combustion process must be taken seriously, for both efficiency and safety. Our Gas Safe engineers test combustion, inspect flues, and carry out any remedial work required to bring the boiler back into safe operation.

Common Commercial Boiler Faults We Repair

Commercial boilers are complex systems that work hard to keep businesses, workplaces, and commercial properties warm and operational. Over time, components can wear out, pressure can drop, and electronic controls can fail, leading to reduced efficiency or a complete breakdown. When this happens, a fast and accurate diagnosis is essential to minimise downtime and prevent further damage to the system.

Our experienced engineers regularly deal with a wide range of commercial boiler faults, including ignition problems, circulation issues, electronic control failures, and flue-related safety concerns.
