The chimney system must be designed to allow for easy provision for sweeping and maintenance. Sweeping must be carried out by competent person. On solid fuel applications a list of HETAS registered sweeps can be found at www.hetas.co.uk. under no circumstances should chemical cleaners or mild steel tools be used to sweep stainless steel chimneys. Cleaning and inspection of the chimney system should be carried out at least once a year, along with maintenance of the appliance, but it is recommended that chimneys serving solid fuel appliances be swept at least twice a year, at the end of the heating season to remove any deposits, which may have built up during the season, and at the start of the next heating season to check for any blockages or deposits.
