Unplug your TV, laptop and smartphone tonight. A warning is being issued to all homes in Britain

Experts urge gadget enthusiasts to turn off devices at night, but never disconnect your Wi-Fi.

If there are a lot of tech devices in your home, it may be a good idea to turn on the power switch and unplug them at night. Not only does turning off the power of gadgets – such as TVs, laptops, PCs and coffee makers – improve safety, but it can also save huge amounts of money over the year.

That’s according to the team at Signal & Power, who say failing to turn off certain items can be surprisingly expensive, shorten the lifespan of products and pose hazards.

“Some appliances can still consume power even when turned off, which not only increases energy bills but also creates a potential fire risk!” exclaimed Signal & Power.

As an example of the savings that can be made, not charging phones overnight could save £10 a year and switching off TVs, PCs and consoles could reduce costs by up to £60 a year.

In fact, it’s a good idea to unplug laptop chargers when not in use, as they can still consume power even when the PC is unplugged. “Laptop chargers can consume a small amount of power even when not connected to a laptop. Overheating or malfunctioning can also pose a fire hazard. Unplugging the power cord can save you £5 to £10,” says Jae Ro, an expert at Plug Specialists, Signal & Power.

Other things to look out for include coffee makers. Disconnecting these popular machines not only saves money, but also extends the life of the device.

“Many coffee makers have a small internal heater that consumes electricity even when the machine is turned off,” Ro added.

“Faulty components can also lead to a fire hazard. If you unplug them at night, you can save around $10-$15 per year. By unplugging them, you can also protect them from power surges or fluctuations, which can their lifespan is extended.”
