Fan error means your electricity bill could be £20 higher next month

The Met Office predicts that 2024 could be the hottest year on record, leaving people looking for ways to beat the summer heat. But the experts in BOX have revealed how much it costs consumers to run the fans, warning they could see an increase in their electricity bills.

To calculate the cost of running a fan, you need to know how much you pay for a unit of energy (1 kw), which should be shown on your energy bill. According OfgemaThe national average price per pence/kWh of electricity is 24.5 pence.



Next, you need to calculate the kW power of your fan. You can do this by checking its wattage, which can be found on the fan or in the instruction booklet. Once you know the wattage, convert this figure to kilowatt-hours by simply dividing the wattage by 1000. This will reveal the amount of energy your fan uses per hour.

Multiply these two figures, the cost of one unit of energy by the kW output of your fan, and you will get how much it costs to run your fan per hour. To find out how much this costs you per day, you can multiply by how many hours your fan is on.

Here are some examples:

  • Box fans consume 0.073 kWh of electricity per hour at maximum speed. With an average electricity price of 24.5p, these fans can cost up to 1.79p per hour. For an eight-hour workday, this would cost 14.32p.

  • Tower fans consume an average of 0.0565 kWh and cost around 1.38 pence per hour to run. If left on for 24 hours, it would add around 33.12p to your energy bill.


Andy Kerr, founder of BOX said: “As temperatures rise, consumers are often looking for ways to reduce their bills after a long, cold winter. However, it is possible to cool your home cost-effectively with fans during the summer months. While the average 110w floor fan uses 2.7p of energy per hour or 64.8p per day, which would add £20.05 to your monthly energy bills, this price can be reduced if you are strategic with your fan. and use your strengths.

“Many will keep their fans in storage during the colder months. However, this means that they will have collected a lot of dust once you take them out, reducing their efficiency. Before turning them on, be sure to remove dust from the blades and any other surfaces before using the fan to increase its efficiency.

“As summer approaches, more people across the UK will be looking to invest in or take out their fans to keep them cool. While energy consumption remains a concern for many, running a fan is not as expensive as one might assume.”
