The agency picked up three special prizes and four awards. To supplement its Grand Prix, two Golds and one Silver, it also won Bronze for its Cadbury Biscuits work.
The night's other big winners included RKCR/Y&R for its Home Office campaign aimed at lowering the risk of theft, and Abbott Mead Vickers BBDO for its contributions to sales at retail giant Sainsbury's.
The former's 'Acquisition Crime' campaign, which ran across TV, radio and print, is claimed to have cut the cost of crime to the taxpayer by up to £190m.
The latter, encouraging Sainsbury's shoppers to 'Try something new today', delivered an estimated £2.5bn extra revenue for the supermarket.
The award for Best Small Budget went to DDB London, for a campaign it developed for luxury fashion brand Radley.
Following its acquisition by private equity in 2006, Radley tasked DDB with raising awareness of its handbag range and improving desirability. The campaign brought a return of £5.57 per £1 spent.
Meanwhile, Red Bee Media won a Gold award for its part in rebranding pay-TV channel UKTV G2 as Dave, and the reframing of its content under the 'Home of witty banter' strapline. The Red Bee-conceived launch push for Dave featured heavy use of outdoor sites and PR exposure.
Silver award-winners included RKCR/Y&R for Dan-one Activia, Ogilvy Advertising and MindShare for Unilever-owned Dove, and MCBD for Waitrose.
