Posted by Mike Gordon on 24 July 2015 08:29 AM

The following table has been extracted from the Air Conditioning Scheme Operating requirements for auditing.

DCLG requires the following as ‘minimum evidence’


Minimum Evidence Requirements


Dates and times of Air Conditioning Inspection.

Site Notes shall normally be sufficient for this


Signed and dated Site Notes.


Data file relating to information entered by the EA as part of the compilation of the ACIR.

Design Floor Plan, elevations, sections which allow the ACIR to be assessed.


Arial view of building from Google maps or similar that clearly identifies the building and site layout to confirm orientation, or a hyperlink to the satellite view of the building.


Contemporaneous schematics demonstrating AC systems in buildings. For Level 4 buildings these can be representative so long as they are produced to cover the full range of systems in use in the building


Evidence of zoning shall be by way of an annotated drawing of the building identifying the zones.


In buildings with many zones, photographic evidence shall be provided to support zone classification, and system types.


Photographs of all external elevations: front, rear and side(s) where practicable and necessary


Photographs supporting identification of existing system, component, or practice failures.


Supplementary calculations undertaken by the assessor.


Additional evidence required to justify the inclusion of recommendations.



  • Remember to sign and date your site notes; this needs to be reflective of the actual inspection date.
  • Photos need to be provided individually in their original jpeg format (not embedded into a pdf or word document). This allows the date taken to be checked against the nominated inspection date.
  • Site notes need to be scanned and not photographed.

The above table will be used as part of our auditing process; missing evidence will be clearly marked and could have an impact on the auditors ability to complete a satisfactory audit.


Please review your Inspection and evidence submission processes to ensure that you are able to comply with the Government Requirements.
