The web form posts itself directly to ask.com, so the only people who know you have searched are ask.com themselves (your web browser sends no data to Surefish at all when you search).
Not only that, I cannot see any source of revenue whatsoever, other than ask.com's normal adverts.
In short, the only way this could work is if Surefish or Christian Aid have convinced ask.com to donate portions of their own advertising revenue to Christian Aid whenever they receive an HTTP_REFERER from surefish.co.uk. Which I doubt.
