My house was empty for 8 months, I continued to pay my direct debit but no usage and they still demanded £47 final payment after my final meter reading. Gas from 19th Jan - 16th feb was £92! Man on the phone was adamant it was all correct so my house cost me at least £700 to stand empty. A new build energy efficient house, EON need new calculators and decent software for billing. I'm sure I'm not the first they have robbed blind. Would definitely not recommend these to supply your energy.
