What’s the Ideal Thermostat Setting for Winter? 

December 13 2024

As the days grow shorter and the chill sets in, finding the ideal thermostat setting becomes essential for maintaining both comfort and energy efficiency. But what’s the perfect balance? Should you prioritise cosiness, cost savings, or environmental impact? Let’s investigate – to help you decide. 

The Recommended Winter Thermostat Setting 

Energy experts often recommend setting your thermostat to 18°C to 20°C during the winter months. According to the UK’s Energy Saving Trust, 18°C is considered the optimal temperature for maintaining comfort and safety while also saving energy. For older adults, young children, or individuals with health conditions, a slightly warmer setting (around 21°C) might be more appropriate. 

“Turning your thermostat down by just 1°C can reduce your heating bill by up to 10%,” says the Energy Saving Trust. This small tweak can make a big difference over the course of the winter. 

Why Does It Matter? 

Your thermostat setting impacts more than just your energy bill. It also affects: 

  • Your Comfort. Finding the right setting is essential for keeping everyone in the household comfortable without overheating or underheating the home. 
  • Your Health.  Temperatures below 16°C can increase the risk of respiratory issues, especially for vulnerable groups. Maintaining at least 18°C is critical for health and well-being. 
  • Your Carbon Footprint. Heating accounts for about 63% of energy use in UK homes, according to the Department for Business, Energy & Industrial Strategy. Keeping your thermostat at an efficient setting reduces your household’s environmental impact. 

Daytime vs. Nighttime Temperatures 

During the day, 18°C to 20°C is generally sufficient for most homes. At night or when you’re out, lowering the thermostat to around 15°C to 16°C can save energy without letting your home get too cold. Modern thermostats with programmable or smart features make it easy to adjust the temperature to suit your schedule. 

Tips for Staying Comfortable 

If turning your thermostat down to save energy sounds unappealing, try these tips to stay cosy without cranking up the heat.  

  • Layer Up! Wearing warm clothes indoors can help you feel comfortable at lower temperatures. 
  • Use Thermal Curtains. Closing curtains in the evening helps retain heat, while letting in sunlight during the day can naturally warm your home. Add blinds for that extra layer of window insulation. 
  • Insulate Your Home. Proper insulation, draught-proofing, and even small measures like placing rugs on hardwood floors can help keep the heat in. 
  • Zone Heating. Focus on heating the rooms you use most often and close doors to keep the warmth where you need it. 
  • Smart Thermostats. If you’re still using a traditional thermostat, upgrading to a smart meter could help you find your ideal setting more effectively. Smart thermostats, such as Hive or Nest, learn your habits and adjust the temperature automatically, saving energy and maintaining comfort. 

The National Energy Foundation notes, “Smart thermostats can save households up to £75 per year on their heating bills by tailoring heating schedules to the household’s actual needs.” 

The Ideal Setting Is Personal 

Ultimately, the ideal heat setting depends on your household’s specific needs. Consider your health, lifestyle, and budget when deciding on the best temperature. And remember, every degree lower not only saves money but also contributes to a greener planet.
