What is the ideal room temperature for your home?

Ideal room temperature depends on a number of factors, from age through to the type of room.

For example, living rooms are generally places we rest and sit still. Therefore, a living room needs to be a slightly higher temperature than say a kitchen.

But before we get into the intricacies, let’s explore average household temperatures to work out what temperature we should set our thermostat. This is why it is so important to ensure your boiler controls are working all year round.

Indoor temperature guidelines:

•            18C–21C — Comfortable temperature

•            Higher than 24C — Cardiovascular risk

•            Lower than 12C — Cardiovascular risk

•            18C — Minimum for Comfort

•            12C–16C — Respiratory risk

•            9C — Hypothermia risk

What is the minimum room temperature?

 A temperature below 18 degrees is now recommended as too low for the UK room temperature. But if you are under 65, you can drop down to around 16 degrees if this makes you more comfortable. 

Central heating temperatures for the elderly will be different from a normal house temperature.

It is recommended if you are over 65 years old or have an illness, room temperature should not drop below 18 degrees. If you’re at all concerned about temperatures check out this NHS guide on how to stay well in winter.

What temperature is too cold for a house in the UK?

The cold temperature in your home is classed as 12 °C or less; this will not be a comfortable house temperature.

You would be uncomfortable trying to get warm, and restless and you will more than likely struggle to get to sleep, leaving you tired, not refreshed, and grumpy the next day.

Nobody wants to have to ice-cold feet or feel like their poor nose is going to fall off when they are trying to sleep. The optimal room temperature is more important than you think. If you think your boiler is the issue then you should consider a boiler replacement.

Studies have shown that the average room temperature in the UK is 18°C. What’s interesting however is that UK residents think the optimum room temperature is between 20 and 22°C.

The best combi boilers and best system boilers can maintain both of these temperatures very efficiently. But it’s worth noting that if you’re in the 20–22°C group, you may be overpaying on bills.

Reducing what is your normal room temperature by altering the thermostat settings by one or two degrees can make a huge difference to your energy usage. If you still seem to be paying over the odds for energy, you may need a new boiler, especially if yours is old and inefficient. An energy-efficient combi boiler can save you up to £580 on your energy bills every year.

What is the ideal bedroom temperature in the UK for sleeping?

Achieving the correct room temperature is extremely important to ensure that you create the best sleep environment. Good sleep impacts your health, skin, concentration levels, and general wellbeing.

The Sleep Council confirms that your body heat reaches its maximum temperature in the evening, and then your body temperature drops to its lowest levels when you are sleeping.

To ensure your body can achieve the temperature it needs for a restful sleep, ensure your room temperature for sleeping is between 16 °C to 18 °C for a bedroom. For those over 65, you’ll want to stick to 18°C and not let it drop below. The older we get, the less our body needs to cool at night, therefore the healthiest bedroom temperature is slightly higher for those in their later years.

Over 24 °C is too hot for your bedroom if you want to be comfortable and wake up feeling revived, refreshed and bouncing out of bed ready for a busy day at work.

Does ideal room temperature change for summer and winter? 

The weather outside has a major impact on a good room temperature throughout your home.

The wind could be blowing and affecting one side of the house more than the other. Therefore you need to alter one side of the house temperature but not the other.

You wouldn’t want to do both and waste energy and make the energy bill bigger when this is not necessary. This is why it is a great idea to have a thermostat to keep an eye on temperature fluctuating and also have the availability for you to be able to change the temperature to what suits your body at that time or that day.

In the living room or the living areas, you will more than likely alter the thermostat to higher degrees than you would have in the bedroom as this is your time to relax and be cosy.

Although, everybody is different and if you like to be energy-saving and keeping the bills low, you may take advantage of the smart meter or the thermostats and play with the temperature dropping and wearing more layers. The living room temperature in the UK is recommended to be higher than your bedroom temperature.

Extra blankets, suitable warm sleepwear, and the correct tog or heavier duvet weight will bring further comfort and energy saving in the cold Winters.

Whilst aiming for the recommended bedroom temperature in the UK, which is 18, 19  or 20°C. The higher the duvet tog rating, the warmer and cosier you will be.

In Summer, you may need to alter the thermostat, open your window, lower the weight of your duvet and switch your heating off to drop the temperature down to the recommended 18 or 19 °C.

The best tog for your duvet depends on the time of year, in Spring and Summer a 2.5 to 7 tog will keep you comfortable whereas in Autumn and Winter 10.5 to 14.5 will keep you at the ideal temperature.

You can also purchase all-weather duvets which allow you to clip thinner duvets together or separate them depending on the temperature outside.
