Standards
Search the HETAS list of relevant industry standards
One of our objectives as an organisation is “Ensuring that HETAS is seen as offering an understandable and secure route through safety standards and relevant regulation in support of our organisational purpose.”
There are a large number of British Standards and European Standards that apply to the solid fuel and biomass industry that affect everything you do on a daily basis.
HETAS registrants can access quick links to all these Standards on the BSI Shop via the HETAS Technical Hub (login required)
