Chimneys in Thatched Properties (HTN001)
Following reports by The National Society of Master Thatchers reporting around 100 thatch fires a year with the majority being caused by chimney related problems when used with a multi fuel or wood burning stove. HETAS has produced a guidance document outlining the Building Regulations requirements that will protect the thatch from heat transference through the chimney structure.

Reporting unsafe work
Where unsafe work is identified the first and most important action is to inform the user that continued use could be dangerous so not to use the appliance. Where possible, identify what work can be done to rectify defects and advice the owner/user.
If the dangerous work appears to have been done by a HETAS installer, give the user our contact details email@example.com ; 01684 278170 and ask them to contact us. If it seems unlikely that they will follow up the complaint, please let us know what you consider the problems are and we will check registration details and investigate further.

If the work was not by a HETAS registrant and there is no other means of pursuing the installer we may still be able to help by giving advice and further contact details. Again, contact the HETAS team for further advice.

Risks from redundant solid fuel back boilers
The Health and Safety Executive (HSE) together with assistance from HETAS has issued safety guidance following several incidents in the last five years, three of which resulted in serious injury, and sadly in one case, a fatality. The redundant solid fuel back boiler had been left in a sealed condition and sometime later, when a coal or wood fire was lit in front of the boiler, the unit heated up sufficiently for the internal pressure to cause the boiler casing to explode.
