The H003DS course features information on all relevant Building Regulations as well as the British and European standards currently used in the solid fuel industry.

There will be both theory and practical training on:

  • Instruction on all aspects of dry appliance installation
  • The correct installation of hearths and fireplace
  • Different types of chimney and connecting flue pipe
  • Identification of faults and the correct use of terminals
  • Commissioning and servicing of dry solid fuel appliances

Candidates will undertake a theory examination and practical assessments following their classroom tuition. Successful completion of this course can lead to HETAS registration as a competent installer, which means you are able to sign off your own work with Building Control bodies.


To attend this course you will need at least one of the following:
