EDF are quite possibly the worst companny I have ever dealt with if you have any sense go no where near this company. EDF are that bad that I never wrire reviews how ever I felt best to warn everyone I can to never ever use this company. I was forced to use EDF due to my previos company going bust and could not change supplier. The billing system they use to to raise a finger in the air and guess how much energy you use then add on another £200 on top of it! Get a smart meter they said we can then charge you for you use!! oh no you then get 2 bills a month which are completly different! you pay one and then get a letter saying you are in debt and they dont want to send pepole round but may have to. Please dont even try to use the call centre or even worse the AI chat bot!! Conclusion - never join them and leave as soon as you can!!
