Canopy and extraction cleaning are carried out to the standards and specification of the Heating and Ventilation Contractors Association (HVCA) Standard TR19. Extraction systems will accumulate deposits of grease and over time this build up can present a significant fire hazard. Even with an efficient extraction system and a regular programme of filter cleaning the grease will still build up within the extraction ducting. Any build up will reduce the ventilation efficiency that will result in overheating presenting a fire risk. In addition, the extraction system will produce excessive humidity which leads to strong odours that can permeate the building.
Detailed extraction cleaning includes a total degrease of canopy systems, with all filters removed, cleaned and thoroughly sanitised.
Catering business insurers require evidence that fire risk assessments have been completed and that extraction systems have been cleaned by a professional contractor at regular intervals. All our works are certified on completion.
The HVCA recommendations for cleaning frequencies
