Finding your ideal home temperature

Setting your home's temperature isn't a one-size-fits-all task; it depends on WHO lives there and which room you're in. Getting it right ensures both comfort and health.

General comfort recommendations

For most healthy adults, the World Health Organization (WHO) strongly recommends a minimum indoor temperature of 18°C during cold seasons to protect health. This temperature is generally considered sufficient to prevent the health risks associated with cold indoor environments and serves as a sensible baseline for general comfort in common areas.

Health considerations for all ages

While 18°C is a good starting point, certain groups need a warmer environment. For the elderly, infants, and those with chronic health conditions, maintaining a slightly higher temperature, typically between 20-21°C, is often recommended to prevent health complications and ensure comfort. This is particularly important in bedrooms and living areas where they spend significant time.

Optimal sleeping temperatures

For a good night's sleep, most experts suggest a bedroom temperature between 16-18°C. This range helps the body regulate its core temperature for optimal rest. Going too high can disrupt sleep, while too low can lead to discomfort and potential health issues.

Achieving energy efficiency without sacrificing comfort

The idea that energy efficiency means living in a cold home is a myth Fuse Energy is here to dispel. With smart management, you can maintain comfort while reducing your energy consumption.

How much electricity does the average UK home use?

The average UK home uses around 2,700 kWh of electricity per year1, which is roughly 7.5 kWh per day. This figure represents the median consumption for a typical household, serving as a useful baseline for understanding and managing your energy usage and identifying potential savings.

Making small adjustments can lead to significant savings. For instance, reducing your thermostat by just one degree Celsius is commonly estimated to save around 10% on your heating bill.

Smart thermostats and zonal heating

Modern smart thermostats offer precise control, allowing you to program your heating to suit your schedule and even learn your preferences. Zonal heating systems take this a step further, letting you heat individual rooms or areas only when they are in use. This prevents wasted energy on unoccupied spaces, giving you more control and reducing overall consumption.

Insulation and draught-proofing

Beyond thermostat settings, ensuring your home is well-insulated and free from draughts is fundamental to maintaining a comfortable temperature efficiently. Proper insulation in walls, lofts, and floors, along with sealing gaps around windows and doors, prevents heat from escaping, meaning your heating system doesn't have to work as hard.

Seasonal temperature adjustments

Your ideal home temperature isn't static; it should adapt to the seasons.

Winter recommendations

During colder months, aim for 18-21°C in living areas when occupied, dropping to 16-18°C in bedrooms overnight. If you're away from home for extended periods, setting your thermostat to a minimum of 12-15°C can prevent pipes from freezing and damp from setting in, without incurring high heating costs.

Summer considerations

While heating is less of a concern, maintaining comfort in summer might involve ventilation or cooling. If you have air conditioning, setting it to 23-26°C can provide relief without excessive energy use. Prioritise natural ventilation by opening windows in the evenings and mornings, and use blinds or curtains to block direct sunlight during the hottest parts of the day.
