The standard basically now seems to just be BRCGS - the "brand reputation through compliance" thing doesn't really seem to be used by BRCGS themselves, other than on the front page of their annual report.
Hi pHruit,
I can appreciate djammur's confusion. "Brand" can be a highly flexible entity.
This topic was previously "investigated" here in 2019 albeit with a variety of conclusions -

There does seem to be some "basis" behind the interpretation of BRCGS as "Brand Reputation ...." , eg see -
https://www.highspee...standing-brcgs/
https://1stc.uk/what...rcgs-stand-for/
However it is unclear (to me) as to whether the above "name" was more a case of "bestowed upon" rather than chosen.
Google seems to have become equally confused eg -
BRC is now BRCGS – which stands for British Retail Consortium Global Standards. Essentially, they just incorporated the name of the standards that they are known for across the food industry. ... BRCGS is simply a brand change to adopt a common industry name for the standards BRC uses.
and yet also
Formerly the British Retail Consortium, Brand Reputation through Compliance (BRC), is a globally recognised UK trade organisation. Which established a series standard to help companies comply with food safety legislation, and to provide guidelines for the manufacture of safe, quality food products.
Regardless, your (top) comment on "absence" seems to be justified by examination of BRCGS's own page and perusal of the report linked within -

@djammur - the answers to yr 3 specific questions seem to be that from an auditee's POV, "BRC" = "BRCGS" so > (No x 3)
