The Home Office said FIPs will work with families by challenging and helping them to change their behaviour.
'For example the cost to the taxpayer can be between£250,000 and£350,000 per family per year for a range of interventions by public services including social, children's and housing services, policing, court services, criminal justice agencies and others.'
The Home Office is putting in£15m kickstart funding for two years - topped up with Neighbourhood Renewal and Supporting People funding - with mainstream funding after then.
'Evidence indicates that money is saved through this scheme and councils are willing to undertake it,' said the spokesman.
Louise Casey, the government's coordinator for Respect, said:
'These projects grip families and use enforcement action and intensive help, and are proven to turn families around. These are families that in the past may have been written off by agencies as 'lost causes' - but now will be offered the right help and incentives to become decent members of their community and give their children the opportunity to grow up with a chance in life.'
Clare Tickell, chief executive of children's charity NCH, said:
'Families who are behaving anti-socially often have incredibly complex problems, problems that can have a ripple effect on an entire community. Getting to the root of the problem can change behaviour forever.'
Different levels of intervention may be used at different times as circumstances and behaviour changes. At the most intensive level families who require supervision and support on a 24-hour basis stay in a residential unit.
Average project costs range from around£8,000 per family for those receiving outreach help in their homes or living in managed properties to around£15,000 for services providing more intensive services (in a residential core unit). Government is contributing about£5,000 per family of this through funding under the Respect programme. (This excludes resources available to local authorities through mainstream funding such as Supporting People, neighbourhood renewal and other local authority revenue streams.)
