Ofcoms monthly Internet and Broadband Update can be found here. This May 2004 update provides data for upto April and February 2004, on subjects like coverage of broadband in the UK and the number of subscribers on the various services.
Interestingly the number of UK adults that have the Internet at home, and who are using broadband exceeded those using metered narrowband services for the first time in February 2004 (27% versus 25%). 67% of people are still using narrowband (dialup) in its various metered and unmetered forms, and just 1% are using ISDN.
