I am contacting ombudsman energy as they are charging me more than agreeing on contract. Be extremely careful if you have smart meters installed on your property. ask the engineer to sign a paper indicating the date of the exchange, and the last reading, his name and the name of his company. Shell energy pretends smart meters have been installed in May. The have been changed in July. They reporting the reading of July as May reading and they are charging me 2 extra months of energy consumption. It is entirely dishonest, that's pure robbery and I have had to pen a case with Ombudsman. Be careful if your supplier is Shell Energy (ex First Utility). Be careful with smart meters. DISGUSTING, UNFAIR, ROBBERS.
