Faulty smoke and carbon monoxide alarms are being sold on eBay - here's how to spot them

eBay has been accused of putting lives at risk by listing hundreds of faulty smoke and carbon monoxide alarms on its site.

Consumer watchdog Which? discovered more than 140 listings for unbranded alarms that had failed previous safety tests, and that the auction site had already been warned about.

Faulty and dangerous

The Which? investigation said the devices that failed its gas detection tests accounted for 91 of the cheapest 200 carbon monoxide detectors listed on eBay's ‘Buy it now’ auctions.

The devices that were unable to detect smoke comprised of 50 of the cheapest smoke alarm listings.

Almost half (50) of the ineffective carbon monoxide detectors were identical to the ones that the consumer watchdog warned eBay about three years ago, while more than three fifths (34) of the smoke alarms listed were for a device Which? had contacted the site about twice before - in 2018 and earlier this year.

Which? claimed that eBay had known “for years” that some of the products listed for sale on its site were unsafe.

eBay removed the listings for the dangerous products each time it was notified. However, there is no system in place to prevent sellers from re-listing the alarms and many have reappeared for sale, potentially putting lives at risk, Which? said.

The auction site has since removed the 141 faulty alarm listings that Which? identified, all of which were unbranded.

Warning to households

The investigation also found smoke and carbon monoxide alarms that had failed safety tests listed on two other online marketplaces, AliExpress and Wish.
