A qualified gas engineer will guide you on system selection, energy performance, zoning, and future maintenance considerations.

Commercial Heating Repairs & Maintenance
Breakdowns and system faults can interrupt your building’s comfort levels, productivity, and compliance. Our commercial heating repairs support businesses across Bristol, Chew Magna, Radstock, and the wider South West, providing fast diagnostics and dependable maintenance by an experienced commercial heating engineer.
Many of the systems we repair show similar issues, including:
- Inconsistent heat distribution throughout the building
- Unexpected shutdowns that disrupt day-to-day operations
- Rattling, banging, or vibrating noises from units or pipework
- Fuel inefficiency that increases running costs
- Control system faults or unresponsive thermostats
- Gas or water leaks within the system
- Component failures involving pumps, fans, valves, or burners
We provide both routine maintenance and rapid-response commercial heating repairs, helping reduce downtime, prevent long-term damage, and extend system lifespan. Other services include leak detection, flushing and cleaning, component replacement, system balancing, and performance testing.
For buildings with older or heavily used systems, proactive servicing is essential to maintain compliance and comfort. Ongoing maintenance helps reduce the risk of disruptive breakdowns and improves overall efficiency and safety. Many clients book regular visits to keep their systems in top condition and to avoid the costly consequences of leaving faults unresolved.
