The contract to deliver property and highway services - including m&e and building maintenance - is expected to be for a 10 year period with an option to extend for a further five years.
It will be delivered by Capita's property and infrastructure consultancy, Capita Symonds.
Paul Pindar, Chief Executive of the The Capita Group Plc, (pictured) said: 'This partnership will support the Council's corporate objectives around performance, prosperity and regeneration.
”We look forward to working with Sefton Metropolitan Borough Council and its employees to ensure that the local community benefits from first class public services.'
The partnership will also cover engineering design, estate management, highways management and drainage.
Further talks are set to take place on the transfer of approximately 150 council employees to Capita Symonds from 1 October 2008 under Transfer of Undertakings (Protection of Employment) Regulations (TUPE).
