We have been serving Hertfordshire and the surrounding areas with central heating and boiler installations for over 20 years. We provide the highest quality workmanship and our Gas Safe engineers are trained to the highest standard.


The cost of a boiler installation depends on the size of your home and the number of bathrooms. You may also need several other upgrades to bring everything up to standard. Converting from a traditional gravity system to a mains pressure one is something we do often, this means careful planning and thoughtful work. A new programmer, circulating pump and thermostat also affects the price. An old heating system may need a comprehensive power flush to clear out old sludge.
