Use of Domestic Gas Appliances Bearing GU Mark

MVO: All domestic gas appliances imported for use in Hong Kong since 2003 must be approved by the Electrical and Mechanical Services Department and bear a GU mark. Aged appliances without a GU mark have exceeded their life expectancy and should be replaced with ones bearing a GU mark. Users should also arrange regular safety inspections for domestic gas installations every 18 months. Please visit the EMSD’s website for details.
