The National Audit Office, the government’s spending watchdog, has launched an investigation into the assurance arrangements for the £4.2 billion Thames Tideway Tunnel – the NAO will publish its report in the autumn.

The Government Legal Department (GLD) has announced the successful completion of the £4.3 billion contract for the Thames Tideway Tunnel, describing the government support package for the Tunnel as designed “to remove project risks that private sector investors would not have been prepared to take.”

Fitch Ratings agency has assigned Bazalgette Tunnel Limited's initial £1 billion revolving credit facility (RCF) a 'BBB+' rating and assessed the Outlook as Stable.

Bazalgette Tunnel Ltd has been formally designated as the Infrastructure Provider for the Thames Tideway Tunnel project.

Following Thames Water’s announcement of Bazalgette Tunnel Limited as the preferred bidder for the Infrastructure Provider to deliver the Thames Tideway Tunnel Project on 14 July, Ofwat has launched a new consultation prior to granting a project licence and issuing a waiver notice.

Thames Water has selected the newly-created,special purpose company Bazalgette Tunnel Limited as the preferred bidder to deliver the £4.2 billion Thames Tideway Tunnel.

The Department for Environment, Food and Rural Affairs has stonewalled a request by Lord Berkeley seeking further information on Defra’s commercial interests in relationship to the funding of Thames Water’s £4.2 billion Tideway Tunnel project.

The Department for Environment and Rural Affairs has refused a request under the Freedom of Information Act 2000 for information about the Thames Tideway Tunnel and the UK Government “Pre-Funded Risk Reserve” on the grounds that disclosure would cause "significant harm" to Thames Water's commercial interests and also "harm Defra’s commercial interests.”

Ofwat has launched a new consultation on the regulatory framework for the infrastructure provider that will deliver the Thames Tideway Tunnel Project.

Credit ratings agency Moody's says that today's announcement by the Secretary of State for the Environment, Food and Rural Affairs that the Thames Tideway Tunnel project is being specified under the Water Industry(Specified Infrastructure Projects) (English Undertakers) Regulations 2013 is a key step towards implementation of the project.
