Ingham and Neale, who is also PRCA chairman, will take part in the event on Monday 8 December.
The PRCA is calling on the industry to donate to Shelter at www.justgiving.com/Mattsleepsrough, to help raise money for families that are facing a housing crisis this Christmas.
Neale said: "While our industry celebrates Christmas with our families, many less fortunate people will be in poorly maintained accommodation or, worse, left to sleep rough on the streets of Britain.
"In addition to freezing temperatures, it’s also likely that Francis snores, so all the more reason to dig deep for this important charity."
Ingham said: "If all our members gave just a few pounds, the public relations industry could make a meaningful difference to the lives of those less fortunate than ourselves this Christmas."
