I am extremely disappointed with E.ON's handling of my recent issue regarding the installation of 40 solar panels and their impact on energy readings. Despite raising concerns that the meter appears outdated and may not be accurately accounting for the energy generated, E.ON’s response has been dismissive, implying there is no measurable impact. This not only ignores the facts presented but raises serious questions about the reliability of their systems and adherence to regulatory standards. Key points of concern: Accuracy and Compliance: Under the Electricity and Gas (Internal Markets) Regulations 2011, suppliers are obligated to maintain accurate metering equipment. If the meter is faulty or outdated, E.ON must take immediate action to investigate and resolve the issue, which has not occurred. Billing Discrepancies: The Electricity Act 1989 requires suppliers to provide accurate billing. Historical inaccuracies, coupled with this unresolved issue, suggest a breach of this duty. Deflecting Responsibility: Instead of addressing the issue directly, E.ON directed me to escalate to the Energy Ombudsman prematurely. The Ombudsman exists as a last resort, not as a way for suppliers to avoid their obligations. Safety Risks: An outdated meter could present additional safety concerns that E.ON has shown little urgency to address. Customer Involvement: Despite my offer to involve my solar installation company at my own expense to facilitate the investigation, E.ON has not taken the necessary steps to resolve the matter. This experience has left me with little faith in E.ON’s commitment to customer service, safety, and compliance. I hope this review serves as a warning to others considering doing business with E.ON. E.ON must prioritise resolving customer issues rather than deflecting responsibility. A site visit to inspect the meter and address these concerns is not just a courtesy—it’s a legal and ethical obligation. Avoid this company if reliability and accountability are important to you.
