Carbon monoxide alarms

Carbon monoxide and smoke alarms, new and certified to the British and European standard.

Certified to BS EN 50291, and new. An alarm only counts as tested if it meets BS EN 50291; Stockwise lists only listings that state it. Avoid unbranded alarms: one that does not name its maker and its standard has not shown it was tested. Fit one in every room with a fuel-burning appliance and test it monthly. Alarms are never rated Buy on price alone.

eBay links open the listing on eBay, where you buy from the seller under eBay's terms. If you buy, Little Jam Jar Ltd may earn a small commission at no extra cost to you; verdicts never take that into account. Prices and stock can change after the check time shown.

No buy-rated listing in this class at this check: the fair ones come first, at about the typical price.
