Comms chiefs from the NSPCC, Cancer Research, Banda's, Childline and Leonard Cheshire attended the conference hosted at Crisis's Skylight Cafe.
Institute of Fundraising chair Joe Saxton said the meeting was 'incredibly positive'.
'We asked people whether there was a need for a new body, and if so, whether it should have a broad or narrow remit,' said Saxton. 'The answer to the first question was "yes", and the second was "broad", so now we need to work on the practicalities of setting the administration up and securing funding.'
Comms chiefs, who have considered the move since July (PRWeek, 5 August), concluded that the new body would not attempt to recreate services and training offered by organisations such as the CIPR's Fifth Estate charity sector group.
'We should be offering something different to other bodies rather than treading on their toes,' added Saxton.
'There is nothing that offers networking opportunities to charity communicators,' he added.
Organisers are planning to approach more charities, the Home Office and the Charity Commission to gather extra support for the body.
