Product safety alerts added to four tested cooker hoods

Four cooker hoods were found to fall short of fire safety requirements in our independent test lab
Safety alert on a cooker hood

Keeping your kitchen fire-safe is crucial because it's the most likely place for a fire to originate in your home. According to the London Fire Brigade, around 60% of house fires start in the kitchen.

Cooker hoods, the extractor fans that suck in humidity and grease from the air while you cook, can come into contact with fire quite easily because of their position above the hob.

One of the most common causes of house fires - chip pans - can cause flames to touch your cooker hood. Flames from frying pans can do this too. If left unattended, these flames can be sucked into your cooker hood's vent and reach the components inside.

That's why your cooker hood's air ducts and its interior components need to be sufficiently fire resistant.

Industry standards are in place to protect us from consumer goods that aren't adequately resistant to common fire hazards like these. But our testing has shown that some cooker hoods sold by major brands don't meet these standards.

The cooker hoods that failed our fire safety tests

Don't Buy roundel

We've just published Don't Buy reviews for four cooker hoods. All contained a component which didn't meet the industry standards for safety when exposed to a flame in our test lab.

Why did the cooker hoods fail our fire safety tests?

We test cooker hoods to the relevant British Standards Institution (BSI) standards. Theseare created by experts to ensure that manufacturers make their products safe and suitable for consumers.

To quote the BSI, a standard is 'a statement of good practice, designed to make things better, safer and more efficient'.

As a part of our cooker hood testing, we perform fire safety tests outlined in the relevant standards (BS EN 60335-2-21:2014 and BS EN 60335-1:2012+A2:2019).

In our test lab, the plastic components in the interior of the cooker hood had to extinguish within 30 seconds of being in contact with a needle flame for them to meet these standards. In all of the cooker hoods listed above, one component burned for too long.

In accordance with the standard, we tested each of the cooker hoods twice and this happened both times.
