Nearly every home in the UK will have at least one or two extension leads trailing through the kitchen or living room. When rooms only offer a limited number of sockets, it becomes challenging to power all the essential appliances.
While extension leads are undoubtedly convenient, they can also pose significant dangers. Numerous household devices consume far too much electricity for an extension lead to manage safely.
According to Hereford and Worcester Fire and Rescue Service, approximately 7,000 house fires occur annually in the UK due to defective electrics, appliances, wiring and overloaded sockets.
There are three devices that should never be connected to extension leads, owing to the substantial power they require.
Kettles consume roughly 3000 watts, electric heaters can equal or surpass that figure, and toasters draw between 800 and 1500 watts.

When several high-wattage appliances operate through a single extension lead simultaneously, the combined demand can rapidly exceed the lead’s safe capacity.
Oliver Nichols from The LED Specialists said: “Extension leads have a maximum load rating, and high-draw appliances like kettles, toasters and electric heaters are among the worst things you can plug into them.
“People often don’t realise how much current these devices pull, and when you combine more than one on a single lead, you’re creating a real fire risk.”
Beyond the fire hazard from wattage, the other concern is the quality of the extension leads themselves.
Extension leads sold in the UK are required to display safety markings and feature built-in fuses — yet many cheap cables available online fall well short of this standard.

Oliver warned: “If your extension lead doesn’t carry the appropriate safety markings, there’s no guarantee it will cut out before overheating. That’s when you move from an inconvenience to a genuine fire hazard.”
For those relying on extension leads throughout their home, the most sensible long-term fix is to have additional sockets fitted by a qualified electrician.
In the meantime, however, it’s essential to ensure that all high-wattage appliances are plugged directly into the wall.
