Ideal room temperatures

The perfect room temperature can be tricky to achieve, particularly if you live with a number of people. But that doesn’t mean it’s not achievable.

While there is no one-size-fits-all answer, the optimal temperature depends on the individual’s preferences, the season, and your home’s climate.

The first step in finding the ideal room temperature is to determine what temperature is most comfortable for you. Most people prefer temperatures between 20-22°C. If you find yourself feeling too hot or cold, you can adjust the temperature a few degrees up or down to find the ideal level of comfort.

Obviously this can vary room to room as it’s unlikely for example that you’d want your living room and bedroom to be the same temperature. The below table shows the comfort criteria designed by CIBSE’s Guide ‘Environmental Design’ on average, what temperature people want their rooms to be.

Room Ideal temperature
Living room 21-23 degrees
Bedroom 17-19 degrees
Office room 20-22 degrees
Children’s bedroom 17-19 degrees
Entryway 19-24 degrees
Corridor 19-24 degrees
Bathroom 20-22 degrees
Kitchen 17-19 degrees

What is the ideal room temperature in summer and winter?

Generally speaking, the ideal temperature doesn’t change from the figures above, but the biggest challenge is trying to maintain these temperatures depending on the time of year.

It’s more difficult to keep your house warm during the winter, but your thermostat can be used to help create a more comfortable temperature around the house.

A central heating system that works efficiently is crucial to maintaining a comfortable temperature, as this will ensure that your home is heating up as it should be. An easy and effective way to keep your heating running smoothly is to make sure that you have your boiler serviced at least once a year.

There’s a few other things you can do to make sure everything is in working order. Firstly, if you’re using radiator covers, there’s a chance that this could be stopping your radiator working efficiently. You can find out more about this in our guide which explains radiator covers and their efficiency.

Secondly, it’s worth making sure that your radiators are working as they should be. For instance, if your radiator is still hot when your heating is off, you will need to get in touch with a qualified Gas Safe registered engineer who can take a look for you.

However, you may find in the summer that you have the opposite problem. In which case you’ll need to look at cooling your room down in hot temperatures.

What happens if your room temperature is too high?

While you’re likely to be uncomfortable if your room temperature is too high, there’s no serious damage you can cause to you or your home. Obviously, it goes without saying that this is within reasonable limits, and higher temperatures can cause heat stress, especially among the young and elderly.

Of course, you’ll feel uncomfortable, in which case make sure your thermostat and radiators are set to the right temperature and follow our guide on how to cool a room down fast.

What happens if your room temperature is too low?

If you have the opposite problem and your room is too cold, you could be at risk of problems such as dampness, mould and condensation. This can happen if you your heating is off for long periods of time, which can cause longer term problems if left, so it’s definitely worth keep on top of

You can also experience issues such as frozen pipes, which can cause bigger problems with your home further down the line.

More importantly, it’s a good idea that you keep your room at a good temperature to avoid any health problems especially for the elderly. As mentioned on the above table, your living room should ideally be between 21°C – 23°C and your bedroom should be between 17°C – 19°C.
