With energy bills on the rise, we’re all looking for simple ways to save money and reduce our environmental impact. But with so much advice out there, it’s hard to know what’s true and what’s not. 

In this blog, we’ll bust some common energy saving myths and share practical advice to help you manage your energy use, whether you’re in a rental or owned home.

1. Is it cheaper to keep the heating on all day?

 

Some people argue that keeping the heating on all day at a low temperature saves money by reducing condensation, but this isn’t entirely true. 

According to the Energy Saving Trust, leaving your heating on all day uses more energy than turning it on only when you need it. The best approach is to use a timer or thermostat to heat your home during specific times, such as early mornings or evenings. 

However, maintaining a consistent, low level heat in colder months can help reduce condensation, especially in areas prone to damp and mould. To balance this, ensure your home is well ventilated and consider using a timer to maintain a moderate temperature. 

If you’re worried about damp or mould in your home, visit our damp and mould support page for guidance, or contact us on 01772 667002 for support. 

2. Should I leave the heating on all night in freezing weather?

Leaving the heating on overnight isn’t energy efficient, but in freezing weather, it can protect your home from frozen pipes, particularly if you’re away on holiday. Setting your thermostat to a low temperature or using a timer during the coldest hours of the night is a good compromise. 

For Customers in rental homes or assisted living, remember that maintenance issues like frozen pipes are something we can help with - let us know via your online account or call us on 01772 667002. 

3. Will turning appliances off save energy?  

Yes, turning appliances off at the plug can save energy. Appliances on standby, like TVs or smart speakers, still use small amounts of power. 

While it won’t save you large amounts immediately, over time, it adds up - British Gas estimates you could save around £55 a year by switching off at the plug. 

For devices like showers with pull cords, it’s best to leave these on to avoid wear and tear, which could lead to repair costs. 

4. What are the benefits of solar panels, and do they save you money? 

Solar Panels

For Customers in rental homes, solar panels may not be relevant as installation and maintenance are typically the responsibility of your landlord. 

However, for Customers who own their homes, solar panels offer great benefits: 

  • Lower energy bills: Once installed, solar panels can reduce your energy costs. You might even earn money by selling excess energy back to the grid through Government backed schemes like the Smart Export Guarantee. 
  • Eco friendly: Solar panels reduce your reliance on non-renewable energy, helping cut your carbon footprint. 

5. Should I close the internal doors to “keep the heat in”?

Yes, closing doors to unused rooms can help conserve heat in your home. This is especially useful in larger properties where you might not need to heat every space. 

For added warmth, consider installing thermal curtains to reduce heat loss through windows. Heat escapes more through windows than doors, so heavy curtains can make a noticeable difference. 

6. Do sockets still use energy when chargers are left plugged in?

Power Socket


Yes, sockets can still draw power when chargers or devices are left plugged in, even if they’re not in use. 

While the amount of energy used is small, turning devices off at the wall can add up over time, saving both energy and money. Switching off at the plug is an easy way to save around £55 per year, according to British Gas.
