A council for voluntary service in Wycombe is asking a councillor to investigate whether a local authority spent more money consulting on cuts to its voluntary budget than it saved.
Wycombe District Council trimmed £45,000 after a three-month consultation. It employed a temporary worker to lead the exercise.
Andrew Long, chief executive of the Priory Centre, is asking the council's observer on the centre's management committee whether the time and cost of the process represented value for money.
"If you consider the time spent by charities and the council, I imagine there is very little saving," he said.
A council spokeswoman said the costs of the temporary worker were "nowhere near" £45,000.
