The recession might create opportunities for mergers between large charities and struggling smaller ones, the finance directors of two large organisations have predicted.
Charles Nall, corporate services director of the Children's Society, said large organisations could help smaller charities that would not be viable by themselves.
"There's an opportunity and an obligation for big charities to look at this seriously," he said. "And if they realise they may not be able to survive, smaller charities should look at this as early as possible.
"They need to make sure they can merge when they are still an attractive proposition, and before the larger charity has received an offer from another organisation."
Martin Birch, finance director of Christian Aid, said larger organisations should consider mergers as an opportunity to acquire expertise or information from smaller organisations.
Previous evidence has suggested that charities would be unsuccessful if they merged to save costs or to increase their supporter bases, he added.
