Companies submitted final business plans to us in April 2004. We scrutinised these plans and took account of companies' annual returns for 2003-04 in setting draft price limits in August 2004. We announced our draft determinations on 5 August 2004 and invited comments and views on these by 13 October 2004. We took account of views expressed and any new information provided to us before setting final determinations in December 2004.
