If you are considering replacing an existing gas fire or a new installation, our expert Engineer will inspect the site, flue, chimney and other specifications for suitability for the installation of a gas fire. Please note:  If an appliance is removed to allow the inspection it may not be reinstated if either the appliance or chimney is considered unsafe, potentially unsafe or does not meet current safety standards and a warning label may be fitted. Please note: Mayne Gas Heating Ltd will not choose your new fire, we will provide the information for you to choose a suitable appliance correctly, in conjunction with a retailer.
