A concordat setting out a framework within which the councils will work together to deliver further efficiencies has been agreed.
Areas being considered for joint working include procurement, asset management, coastal defence work, vehicle maintenance and leisure services.
Fylde chief executive Phil Woodward said: 'Now that we have proven the effectiveness of this approach and provided cost savings for both councils we have signed a concordat for developing other shared service partnerships.'
