Charities and voluntary groups in London have experienced funding cuts totalling about £50m in the past 12 months, according to a survey by the London Voluntary Service Council.
The umbrella body for London’s voluntary and community sector conducted telephone interviews with councils for voluntary service in all 32 London boroughs.
The research found that charities and voluntary groups in London have identified cuts over the past 12 months of about £50m.
The figure includes cuts to local authorities that have been passed on to charities and community groups: Croydon Council, for example, is cutting £1.2m from its annual voluntary sector budget.
It also includes cuts to London-wide organisations, such as the London Development Agency, which ended its £28m London Opportunities Fund programme in March.
Peter Lewis, chief executive of the LVSC, said: "We are asking government at national, regional and local level to enter into proper dialogue with charities and voluntary and community groups about any cuts they are considering.
"This will help decision-makers make the right decisions, protecting the most disadvantaged Londoners and making the most of their dwindling funds."
He added that many of LVSC’s members welcomed the idea of the big society, but were concerned because "its very foundations - voluntary and community groups across London - are being weakened by the cuts before the project of building the big society begins".
