Leading internet service provider (ISP) BT has extended an offer on its internet services and UK landlines until October.

The firm is offering a broadband and unlimited UK calls bundle for £15.99 per month, plus line rental charge, to new customers signing up for web services.

However, as part of the ISP's summer deals season, subscribers receive three months free on the offer enabling them to save £47.97.

The offer is available to anyone signing up for BT Total Broadband and unlimited UK calls before October 1st 2010.

All phone calls of up to an hour in duration are included in the deal, providing they have been made to an 01, 02 or 03 number.

Last week, BT announced that up to 140,000 homes and businesses in the north-west of England are to receive broadband speeds of up to 20Mb.
