I had researched the best plan for me before I rang and spoke to Dominique at ORG600.  She took me through the plan and I had all the necessary details to hand (annual gas and electric usage in kWh and my bank details).  This speeded up the process, though it still took about 25 minutes.  This was because I did have several questions which Dominique was able to answer.  The service was easier than I thought as this is the first time I've switched suppliers.
