I've been using South West Broadband since May 2013 after a recommendation from a friend, and I have been consistently impressed and delighted with their service and their commitment to great customer service.
My confidence in them is so high that I have since recommended them directly to a number of my clients who have all been similarly impressed and pleased.
Unlike some hosting companies I have dealt with, South West Broadband are always prompt, personal and helpful with their support responses. Moreover, they are happy to use their expertise to help you diagnose and overcome technical issues – even ones that aren't of their making. They take heroic amounts of responsibility for ensuring positive outcomes to any problems, and give reassuring updates along the way.
I can't recommend them highly enough.
