Change of Energy Supplier

Today it's raining yet again, so there's not a lot I can do outside. My cheap Gas and Electricity Energy deal came to an end at the end of March and I have been put back onto their standard tarrif, so I have been intending comparing the market to find the cheapest deal.  I use MoneySupermarket.com as they have sent me £30 in the past when changing suppliers using their web site.  It's a very simple process to fill out the online forms, you just need to know how much you are paying each month/year in terms of kWh or money.  Seconds later it displays a list of the deals ranked in order of annual savings.  I decided to go for the greatest saving of just over £200.  This also came with a price freeze until June 2013.  I filled out the forms, including bank details for the direct debit, selecting the debit date, clicked on 'Confirm and Send' and it was done.  I received a confirming email.  Seemples.
