I used to be with Pipex for broadband, BT for phone and Sky for TV. I now have high speed unlimited broadband, telephone including line rental, free UK and international call any time any day and a good family package with no sport or film channels with Sky for around £52.00 per month.
The only difference in the bill month to month is if child one "forgets" not to call mobiles from the landline but I get a fully itemised bill so taxing him is easy.
I'd recommend Sky without hesitation.
