Gas Boiler Service


A regular gas boiler service is essential to ensure the correct and safe operation of your boiler. A defective gas boiler can result in higher energy bills as it may not be operating at the manufactures specified settings. This could also result in the incomplete combustion of the gas fuel, making the presence of the deadly poisonous Carbon Monoxide gas likely.

Carbon Monoxide is a colourless, odourless gas and for this reason it is highly dangerous.
