What is Solid Fuel Installer (HETAS)?

Solid fuel installers fit and service wood-burning stoves, biomass boilers, open fires and chimneys. HETAS is the official body that registers competent solid-fuel and biomass installers in the UK, allowing them to self-certify work under Building Regulations (notably Part J on combustion appliances and flues). A HETAS certificate gives homeowners assurance the appliance was installed safely and that carbon-monoxide and flue requirements were met.
