HETAS is the only government approved competent persons scheme specialising in solid fuel, wood & biomass
All registered installers are trained and regularly assessed as competent.
If you or your builder were to install an appliance yourself, you would have to satisfy Part J of the building regulations. This would involve going through your Local Authority Building Control. The cost are around £300 for the pleasure of a visit from the Building inspector. HETAS registered installers are the only exception. On completion of the installation, the engineer will certificate the works in compliance with current Building Regulations.
