o2 are launching a home phone line from 15th January. I called them yesterday to cancel my broadband. They said home phone service will cost £10.50 per month with evening and weekend calls free and offered this together with broadband for £15.50 per month. o2 are generally good and have UK based customer service. Price will be £5 extra for non o2 customers.
My first post so let me know if need to make any changes.
