Sharing premises with other local authorities has helped Surrey County Council save local taxpayers nearly £3.5 million.
Basing staff in joint rather than separate council offices in the same towns has contributed most of the £3.4m savings on public buildings.
The approach, which has seen adult social care staff move into borough and district premises, is part of the county council’s new agenda to get everyone working together as one team for the benefit of Surrey.
It means workers caring for older and disabled people link up even more effectively with teams in local councils providing services like dial-a-ride transport, home improvements for the disabled or meals on wheels.
Surrey County Council’s Cabinet Member for Assets and Regeneration Programmes Tony Samuels said: “The public sector should be seen as one team working together for the benefit of Surrey.
“If we are going to continue to provide first-class services to residents while also making savings we have to work even better with other organisations – especially councils.
“By housing staff under one roof, we’re all providing even better services while giving maximum value for money by making the very best use of office space.”
Already 2,000 staff have moved offices. The figure includes those who have switched to other Surrey premises to make better use of existing office space.
By the end of the summer social care staff will share the premises of all 11 Surrey borough and districts. The office-sharing programme started a year ago, when staff moved into Guildford Borough Council’s offices.
