The team won a total of six gongs at this year's Local Government Communications Reputations Awards ceremony - more than any other local authority.
LGcomms handed out gold awards to Westminster's parking comms and internal comms teams.
Westminster head of comms Alex Aiken is also secretary of LGcomms. He said that he 'stayed away from both the Westminster submissions' during the judging process.
Other gold winners included London Borough of Islington for best media relations.
