Do TR19 kitchen and ducting cleans have to be carried out by BESA APPROVED COMPANAIES or are there other options?

No, TR19 kitchen and ductwork cleaning does not have to be carried out exclusively by BESA (Building Engineering Services Association). However, BESA is the organization that developed TR19 as the industry standard for kitchen extract and ductwork cleaning, so many reputable companies follow their certification scheme (e.g., TR19 Grease™).

Other Options for TR19 Compliance

You can use any professional ductwork cleaning company as long as they:
✔ Follow TR19 guidelines (whether or not they are BESA-certified)
✔ Provide a TR19 post-clean report (needed for insurance & fire safety compliance)
✔ Hold relevant industry certifications, such as:

• NAADUK (National Association of Air Duct Specialists UK) – Offers TR19-compliant training and accreditation.
• ISO 9001, CHAS, SafeContractor – General health & safety accreditations.
• Independent TR19 training providers – Some companies train staff in TR19 compliance without being part of BESA.

Key Takeaway

You don’t have to use BESA directly, but you must ensure that the cleaning company follows TR19 standards and provides the necessary compliance documentation. Always check their credentials before hiring.
