Commercial Gas Services
Gas Safe registered engineers for gas mains, plant room pipework, gas safety circuits, boiler connections and servicing.

Gas work is part of almost every plant room we refurbish. We alter and upsize incoming gas pipework to suit new boiler layouts, install gas safety circuits with electro-thermal devices and solenoid valves, bond new pipework to earth and paint and identify it to current standards.
At Hadley Wood Primary School the incoming gas main was increased from 2 inch to 4 inch to serve three new 120kW boilers. At Gunnersbury Catholic School we modified the gas services and installed a new gas safety circuit as part of the plant room upgrade.
