• Before you consider installing a multi-fuel stove, you MUST get our written permission. If written permission is not received, we may insist that the stove is removed.
  • Only DEFRA-approved stoves meet regulations and will be considered for permission to be installed.
  • All installations MUST be carried out by a registered HETAS engineer. You MUST provide us with a copy of the installation certificate within seven days of installation.
  • Any installation we approve MUST have a new flue liner installed by a registered HETAS engineer. This will ensure that the stove is correctly and safely installed. The cost is approximately £1000, which you would have to meet.
  • Only smokeless fuels can be used to meet environmental regulations. Using any other fuels may result in a fine of up to £1000 – you must be able to provide receipts to prove you’re using smokeless fuels.
  • You MUST have a working carbon monoxide detector installed in the same room as the stove, which is tested
  • regularly in line with the manufacturer’s instructions. Multi-fuel stoves can produce up to 10x more carbon monoxide than a standard gas fire.
  • We will undertake an annual inspection of the flue.
  • Any multi-fuel stove over 5kw will require permanent ventilation. The cost of installing this will be your responsibility, along with any work we may need to carry out in the property should you decide to move out.
  • If you fail to comply with the above, we will have no choice but to remove the stove and brick up the chimney. This is for the health and safety of you and your family.
