I think this is the best offer at the moment, as TalkTalk are offering unlimited free calls to landline numbers (telewest are currently offering this for £24.99 alone) and this includes BT's line rental charge of £11.
As a bonus, they're now offering 8MB broadband comepletely free with upto 40gb downloads as an additional bonus, which comes complete with free connection and modem.
Remember to go through Quidco for £10 cashback once you join as a new customer.
I hope this new great offer is beneficial for anyone looking for a new phone and internet service provider. :)
