If I could give zero stars, I would. EDF Energy sent me a £288 "final bill" FOUR MONTHS after my account was officially closed — and after confirming in writing that no further action was required. Let that sink in. I submitted my final meter readings. They acknowledged them. They emailed me saying everything was sorted. Fast forward months later, and suddenly I'm being told I owe them hundreds. No explanation. No accountability. Just cold, automated threats and zero concern for the regulatory standards they’re clearly violating. They ignored their legal obligation to issue a final bill within 6 weeks, reversed earlier charges in a shady back-end recalculation, and then decided to gaslight me into thinking I still owe them money. I’ve taken this to the Energy Ombudsman — because clearly EDF thrives on customer confusion, delay tactics, and emotional exhaustion. If you value your mental health, avoid this company at all costs. EDF isn’t just inefficient — they’re predatory with a polite face.
