Voluntary sector campaigns have reached new levels of effectiveness, according to the director-general of the Institute of Public Relations.
Colin Farrington's comments followed an unprecedented number of gongs for charities in the institute's excellence awards.
"Public relations in the sector is going from strength to strength," said Farrington.
"The success of these charities reflects the quality, creativity and effectiveness of communications being carried out in the not-for-profit sector."
The communications team at WWF-UK beat the NSPCC and the Royal Society of Chemistry to win the best in-house public relations team in the public and not-for-profit sectors.
"It was good to be rewarded for our focus on value for money and communications," said director of communications Perdita Hunt.
Development charity World Vision came first in the not-for-profit campaign category for its efforts in engaging people in Scotland on global poverty issues.
British Agencies for Adoption and Fostering won the public affairs category for its campaign to allow unmarried couples to adopt.
