Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what assessment his Department has made of the ability of Thames Water to service the costs of building the proposed Thames Tideway Tunnel.

The Government's Reasons for Specification Notice, published on 5 June 2014, explains in detail why the Government believes that the project is of a scale and complexity that would threaten Thames Water's ability to provide services to its customers. Paragraphs 21 to 35 provide this explanation.

The Reasons Notice is available from the following link:
