The site shall have taken into consideration the following: 

  • appropriateness of the system for the application of the cleaning chemicals during the cleaning operation
  • how the cleaning chemicals are to be supplied to the wash facilities safely (where the chemicals are to be dispensed)
  • storage facilities when cleaning chemicals are not in use
  • the site shall have developed appropriate work instructions for the dilution of chemicals. Work instructions shall be readily available 

A list of DEFRA approved detergents and sanitisers shall be reviewed and this should list the chemicals in use However, it should be noted that DEFRA frequently update the list, so it is possible for a chemical to be on the list at the time of purchase to be then removed at a later stage whilst the chemical is still in use at the site. In such circumstances if the site can prove the chemical was on the list at the time of purchase and that arrangements are in place to move to a chemical on the updated approved list at the next re-order point then this would be viewed as being compliant to the charter requirements.


Verification shall be sought for the following:

  • evidence of training that includes health & safety legislation (where appropriate)
  • detergents and disinfectants are supplied to the wash facilities in accordance with legislation 
  • availability of up to date COSHH data sheets covering the scope of cleaning chemicals manufacturer’s recommendations in relation to dilution rates aligned to legislation.
  • correct storage of chemicals
