If you have an extractor fan installed, you might still wonder about the ongoing costs of running it.

As concerns about household expenses grow, understanding the cost implications of using your extractor fan is essential. This article will explore the costs associated with running an extractor fan and offer tips to maximise its efficiency, ensuring your home stays damp-free without breaking the bank.

The Benefits of Using your Extractor Fan

Extractor fans are vital in maintaining a healthy home environment, especially in damp-prone areas like kitchens and bathrooms. They help expel moist air outside, preventing the build-up of damp and mould that can lead to health issues and structural damage. But what does it cost to keep these fans running efficiently?

Breaking Down the Costs

Extractor fans are relatively low-energy devices. Typically rated between 6 to 40 watts, their electricity consumption is minimal. To put this into perspective, a 20-watt fan running for an hour uses 0.02 kWh of electricity. With the average cost of electricity in the UK around 34p per kWh (as of 2024), running a 20-watt fan for an hour costs less than a penny: approximately 0.68p.

If you use your fan for an hour each day:

Daily cost: 0.68p

Monthly cost (30 days): 20.4p

Annual cost: £2.45

So even if your usage doubles to 2 hours per day, the annual cost remains under £5, making it an economical choice for maintaining a healthy home environment.

Maximising Efficiency

Regular Maintenance

Keeping your extractor fan clean and well-maintained ensures it operates at peak efficiency. Regularly wipe down the cover and check the ductwork to remove dust and debris. A clean fan works more efficiently, reducing running time and energy consumption.

Ventilation Best Practices

Where possible, complement the use of your extractor fan with good ventilation practices. Opening windows and doors when weather permits can help reduce the overall moisture load in your home, allowing your extractor fan to work less intensively.

Conclusion: Small Costs for Big Benefits

In conclusion, running an extractor fan is highly cost-effective. The minimal impact on your electricity bill is vastly outweighed by the benefits of maintaining a damp- and mould-free home.

So our advice is to keep your fan running efficiently, and enjoy a healthier, more comfortable home.
