A procurement policy that encourages organisations to demonstrate the social benefits they offer is being expanded by Camden Council.
An "outcomes-based commissioning" policy, which offers bidders more flexibility when showing how they will meet council needs, was trialled last year and is now expected to be rolled out more widely.
Applicants will be expected to show how they can meet a specific local need, rather than their ability to hit specific targets.
The London council has also released a wider consultation on better working with the voluntary sector, which includes proposals such as a social innovation fund to encourage new ideas and organisations in the borough, full cost recovery when funding services and a consistent rents policy for charities when it acts as landlord.
Neil Cleeveley, director of policy at the local umbrella body Navca, said: "I think we are seeing a trend of the more far-sighted local authorities taking a more strategic look at the relationship."
