The broadband, TV and mobile provider founded in 1997 by Lee Strafford – who has since exited – is a giant in the area and was named 2018’s Which? Recommended Provider for TV and Broadband bundles.
It was floated on the Alternative Investment Market in 2004 and in 2007 the company was acquired by BT Group, but continues to operate as a separate business.
