BAFE is not a trade association. The major difference between BAFE and trade associations is that a company is not paying to become a member of an industry group. Instead a company is establishing evidence of their competence by being independently assessed and Third Party Certificated. Only then are companies allowed to become BAFE Registered.
BAFE do not have "members", the BAFE Register is a publicly accessible database of fire safety companies who are Third Party Certificated via UKAS Accredited Third Party Certification Bodies to specific BAFE Scheme criteria.
