Hello Forum - my first posting so excuse if I'm repeating stuff...

I run a home-based business - and have gradually accrued a mixed bag of phone lines - I bet I could make it more efficient and cheaper, but I'm not sure where to start. I have a mobile, and three separate BT land lines - one is my 'domestic' phone, and two 'business phones', one of which I use for fax / modem, and one for straight phone calls. 

I'd like to hear from forum users who are happy with their broadband supplier or their 'call and line rental package' supplier, so I can take a short-cut to a reliable and good value solution, rather than reinventing the wheel by doing loads of research and shopping around. 

Thanks
