Savings made downsizing Thames Valley Police have resulted in a projected underspend of Â£5.3m according to a new report by the police authority.
Deputy Chief Constable Francis Habgood said reductions had been made in staff, overtime and estate costs in 2011/12.
He said he hoped to invest additional savings into front line policing but that the Â£5.3m underspend was separate.
Thames Valley Police has to find about Â£16m worth of savings in the next financial year.
Mr Habgood said: “This is getting us ready for more cuts we are going to need to make next year.”
Graham Smith, from the Thames Valley Police Federation, which represents police officers, said: “Any underspend now should be spent on operational policing needs in the future.”
