BT has launched a new service capable of delivering download speeds of up to 8MB and upload speeds of up to 448KB for no extra cost although usage limits of up to 40GB will be in place.

The new ultra-fast service - up to four times faster than current speeds currently offered by BT - is available from today to new customers taking BT's Option 4 broadband package.

It will be available to new customers selecting Option 3 from 11 April 2006 and will be offered to new customers choosing Option 1 and Option 2 packages later in Spring 2006.

BT also announced today that customers switching to BT from other broadband providers we be able to benefit from broadband and inclusive Evening and Weekend UK Broadband Talk calls (up to an hour at a time) for just £11.99 for the first three months and then £17.99 thereafter.

Existing BT Broadband customers are being offered a free upgrade to the new higher speed service on a first-come, first-served basis.

All existing customers can go to www.bt.com/getbroadband for information on how to order or pre-register for their free upgrade.

Existing customers regrading to the new service will be subject to a new 12 month contract starting from the date of the regrade.
