I have just spoken to Southern Electric and the guy on the phone told me you are able to fix your energy prices for a year, you can only do it online, if you have paperless billing and pay by direct debit. I have just done mine! Obviously you won't be effected by the price increase on 15th November. They are not advertising this and it can be withdrawn at any time. I thought I would spread the word so if you are with them you can save a few quid
