South Yorkshire Police Headquarters is moving from its base in Snig Hill out of Sheffield city centre to Carbrook.
The new HQ will be based in a former Abbey National call centre building, bought by the force in a £5 million deal.
Nearly 300 staff from three buildings, including the current HQ at Snig Hill, will relocate to the new site early next year.
South Yorkshire Police Chief Constable Med Hughes said: “The force has needed a new headquarters for many years, but we ensured that our operational buildings and frontline premises were a priority.
“Having delivered new district buildings, a forensics building, new vehicle fleet facilities and a new training centre for officers and staff, we are at the final stage of providing our hard-working headquarters staff with accommodation that is fit for purpose.
“Our purchase of the former Abbey National call centre at Carbrook has been funded by the sale of dated facilities at West Bar and other locations.
“The existing force headquarters will become the district headquarters that the city of Sheffield merits and, by acquiring and refurbishing an older building, we will create a new force headquarters for minimum cost.
“The new headquarters will allow us to close expensive, leased buildings and provide accommodation for staff, while also providing a great deal for the taxpayer,” he said.
Charles Perryman, chair of South Yorkshire Police Authority, said: “This development is the culmination of several years’ hard work in finding a suitable headquarters for the force.
“Moving out of Sheffield city centre will provide the force with improved access links to Rotherham, Barnsley and Doncaster.
“We have also been able to secure an excellent price for the building and it will help the police reduce overall running costs, ensuring a more efficient service is provided to the public.”
