An influential committee of MPs has sharply criticised the Department for the Environment, Food and Rural Affairs (Defra) over its handling of three PFI waste projects involving local authorities.

In a hard-hitting report, the Public Accounts Committee found that PFI contracts, which typically last for 25-30 years, did not offer the necessary flexibility to respond to rapidly changing technology and changing policy requirements for waste disposal.

The MPs said Defra had been “unacceptably slow” to intervene in projects that were struggling to deliver the required waste management infrastructure, leading to delays and incurring extra costs.

The report described the Department’s handling of the cancelled Norfolk PFI waste project as “particularly poor”.

Defra had failed to exercise good judgement by agreeing to give funding to the project and then failing to give sufficient consideration to the local impact of its decision to withdraw funding to that project, the PAC said. “This contributed to the contract being cancelled which has left Norfolk taxpayers facing a bill of some £33.7m.”

The committee examined two other PFI waste projects as part of its inquiry, one run by Surrey County Council and the other jointly managed by Herefordshire and Worcestershire councils.

Margaret Hodge MP, chair of the Committee of Public Accounts, said: “It is appalling that lax, poorly drafted PFI funding agreements to support the building of local authority waste processing plants have led to hundreds of millions of pounds worth of grants being made to three councils even though the main waste assets – such as incinerators – have not yet been built.

“Funding agreements with Surrey and with Herefordshire and Worcestershire councils signed by the old Department for Environment, Transport and the Regions, meant central government started paying grants to the local authorities as soon as the contractors began to deliver waste management services rather than waste management assets.

“The supporting PFI contracts signed by the local authorities did not require all of the expected assets to be constructed, resulting in £213.5m in grants having been paid to the councils over the last 15 years with none of the main waste assets to show for it.”

Hodge meanwhile said it was “scandalous that taxpayers in Norfolk have been left in the lurch and landed with a bill of around £33.7m because the Department withdrew its funding for the Norfolk waste plant in October 2013”.
