The Vent Hygiene Elite Scheme, also referred to as VHE, is an accreditation scheme created by BESCA. Based upon a combination of long-established, proven cleaning processes, and updated TR-19 standards, the Vent Hygiene Elite Scheme works to ensure all members conduct work to elite standards - form consultation, through to final service documentation and certification. Vent Hygiene Elite members are required to demonstrate these standards to administrators and auditors from the associations and accreditation arm of BESCA, ensuring their consistent delivery of the highest levels of compliance, competence, and service delivery possible.
