Amazon continues to list potentially dangerous "energy-saving" plugs on its platform, even though it had previously committed to removing them. The consumer group Which? first identified these plugs in 2025 and reported them to retailers, leading to their removal from physical stores. However, similar products reappeared on Amazon shortly after. In August, Amazon's UK Director of Public Policy, Monica Ariño, wrote to the House of Commons Business and Trade Select Committee, stating that the devices had been removed from sale. She also mentioned a technical issue with Amazon's automated classification system, which was preventing some products from being detected automatically. Liberal Democrat MP Joshua Reynolds raised concerns about the fire risk posed by these plugs during a parliamentary hearing in June. He has since said he will write to Amazon for clarification, noting that the plugs are appearing as sponsored ads at the top of Amazon's listing pages. These plugs are being marketed as affordable solutions to reduce energy bills, which is particularly appealing given the recent rise in household energy costs. Which? tested eight of these devices from various online marketplaces, including eBay, AliExpress, Shein, and TikTok Shop. The tests found no evidence that the plugs actually worked as advertised. In fact, the group noted that selling these plugs in the UK would be illegal because they failed to meet basic safety standards. More than half of the tested plugs had ill-fitted socket pins, some of which were too small, not straight, or so fragile they snapped off. Other issues included poor manufacturing, such as the use of non-standard capacitors and inadequate soldering, which could lead to electrical failures. According to product listings, Amazon's "energy-saving" plugs are advertised as "voltage stabilizers" and "surge protectors," claiming to significantly reduce energy bills by improving the performance of household appliances. These devices are typically priced between £10 and £15, making them seem like a cost-effective option. However, they are said to pose serious risks, including fire hazards and the potential for electrocution. Amazon has not yet responded to recent claims about the current status of these product listings.
