Chancellor George Osborne is expected to give government departments an incentive to sell their property under a new plan to raise £25bn.

Next month, Osborne is set to announce the incentive as a way for the government to raise money from its £370bn property assets. Prime minister David Cameron wants civil servants to find ways to use public sector property more efficiently.

Assets that could go up for sale include the Queen Elizabeth II Conference Centre in Westminster in London, depots and other holdings of the Defence Storage and Distribution Agency, and potentially even British Waterways.

• Osborne: departments must look to privatise property
• Spending Review: Asset sales among £6bn back office cuts
• For sale: More than 500 regional development agency assets
• Industry lobbies for commercial development incentive
• Council asset sales set to rise 17% this year
