 In July 2018, Oxfordshire County Council was reviewing costs and liabilities related to its properties following the Carillion collapse; it was concerned about 'latent defects' - normally dealt with as part of the contract with the builder, but with many Carillion businesses in liquidation now less straightforward if claims needed to be made.In November 2018, the council said that auditing Carillion's shortcomings across 162 of its biggest projects for the council had cost it £1.7m; in the process it had identified missing certificates and fire safety issues on building projects, for which it intended to claim costs (as yet unspecified) from Carillion's liquidators.Exactly how much the council owed to Carillion's liquidators and how much the council intended to claim was unclear in January 2019, although in March 2019, the council was reported to be owing three times what it thought it should pay - a figure that "might run into tens of millions of pounds at least".
