30 billion was the last estimate I heard for that.

Theres also an estimate here
The costs of deploying fibre-based next-generation broadband infrastructureOn 15 July 2008, BT announced its strategy for deploying a mixture of FTTC and FTTH in the UK. Its plans involve covering ten million premises by 2012, with FTTH being reserved for areas of new build. The company estimated that this would involve an investment of GBP1.5 billion, which equates to an overall cost of GBP150 per premises passed. During a presentation by Sally Davis (CEO, BT Wholesale) it was also stated that BT expects costs per premises connected to be around GBP350;
afaik the above isnt talking nationwide - just 'some'.. but that cost has to be bourne somewhere.. and just who is going to pay it?

In the early days of adsl a connection wasnt cheap and it cost £30 for a 512kb connection - and it was only the real techies that were prepared to pay a minimum of £30 - often more.
Nowadays adsl is much cheaper and it comes from the likes of 'the T ISPs', and whilst it is good that its now affordable.. theres no mistaking that the quality of adsl provisioned/service has gone downhill as prices drop.
