Kier Group did not defraud Harrow Council, says the report of the investigation published this week.
Sub-contractors had claimed that invoices for maintenance of social housing were being artificially inflated, but the Council's investigation has shown nothing of the sort has happened.
Councillor Tony Ferrari, portfolio holder for major contracts and property, told the Harrow Observer that: “Harrow Council is satisfied that a thorough investigation has concluded that all allegations of corruption within Kier proved unfounded. Following an exhaustive and thorough inquiry the matter can now be put behind us as we focus on building new schools. Kier have delivered a number of excellent school buildings which would have proved impossible without their partnership.”
Ian Lawson, director of Kier Group plc, said: "Kier takes any allegations of this nature extremely seriously and we have therefore ensured that an exhaustive and professional investigation has been undertaken jointly with our client. We are pleased that any allegations against Kier or its employees have proved unfounded and can now draw a line under the matter and continue to concentrate on providing the best possible service to Harrow Council."
