§ Mr. Wigley
To ask the Secretary of State for the Environment what was the total cost of the Thames barrage scheme; and how much of this cost was met by central Government. 
§ Mr. Boswell
I have been asked to reply.
The total cost of works under the Thames Barrier and Flood Protection Act 1972 was some £700 million, with the Thames barrier itself costing some £450 million and associated downstream works, including a second barrier at Barking, accounting for the remainder. Government grants made under the Act totalled approximatly £540 million.
