Public · listed drinks group [1][2][3]
The beer brands have Irish origins; Diageo's London parent office does not make them UK-origin. Carlsberg brewed under licence in Ireland is excluded as a Diageo-owned brand. This is a selected beer catalogue, not Diageo's full spirits portfolio. [1][2][3]

Headquarters, incorporation and tax residence describe different things. A headquarters address does not tell you where all of a company’s tax is paid.

03 / The figures, with context
UK cash corporation tax has not been verified in this ownership review. This does not mean no tax was paid.
Diageo · UK cash reporting scope not reconciled
Annual reporting period not yet verified
This beer ownership review has not established a UK cash corporation-tax payment. Ownership percentages, worldwide tax figures and beer duties do not establish that amount. [1]
These figures have different scopes. They should not be added together or used as a like-for-like tax ranking.
