Air Hygiene Survey & Independent Auditing
MyDuctwork Ltd carries out detailed surveys to assess the internal cleanliness of general supply and extract ductwork systems. We also provide independent audits of kitchen extraction systems following cleaning by another contractor.
Our service includes a detailed report with photographic evidence and recommendations where further action is required.

Independent Auditing of Kitchen Extract Systems
Risk of fire will be significantly increased when sections of the extract systems receive poor quality cleaning, or when sections of the system are being missed completely during the cleaning process. Inadequate management of the grease build-up within your kitchen extraction systems can be a large factor in the spread of a fire.
A range of industry guidance and best practice documents is available to support the effective management of commercial kitchen extraction systems. These include the BESA TR19 Grease (July 2019) specification and guidance published by the RISC Authority, such as:
- RC16B: Recommendations for Fire Safety in Commercial Kitchens
- RC68: Recommendations for Fire Safety in Catering Establishments
- RC44: Recommendations for Fire Risk Assessment of Catering Ventilation
These documents provide guidance on managing fire risks, maintaining extraction systems and supporting appropriate fire safety practices within commercial kitchens.
The Regulatory Reform (Fire Safety) Order 2005 places duties on responsible persons to take appropriate precautions to manage fire risks and protect building occupants.
Article 17 of the Order requires relevant fire safety equipment and facilities to be maintained in an efficient state, in efficient working order and in good repair. Regular inspection and appropriate maintenance of kitchen extraction systems can help support wider fire safety responsibilities.
