What temperature should your house be?

Finding the right temperature for your home in the UK is about more than just comfort; it's a careful balance between staying warm, managing energy bills, and protecting your health. With energy costs a constant concern, many householders grapple with setting their thermostats, often unsure of the optimal settings for different rooms, times of day, or specific household needs. This guide cuts through the confusion, offering clear, actionable advice to help you achieve a healthy, energy-efficient, and comfortable home environment.

Finding your ideal home temperature in the UK

Setting your home temperature effectively means understanding general recommendations and then fine-tuning them for your specific living situation.

General recommendations for living areas

For most healthy adults, a comfortable living area temperature in the UK generally falls between 18°C and 21°C. This range is widely recommended for both comfort and health, particularly during colder months. The NHS advises maintaining at least 18°C in frequently used rooms to safeguard against cold-related health issues.

Night-time and sleeping temperatures

When it comes to bedrooms, a slightly cooler temperature is often beneficial for sleep quality. For adults, an ideal sleeping temperature is typically between 16°C and 18°C. This range helps your body prepare for sleep as your core temperature naturally drops. Going much below 12°C can make it harder to fall asleep, while temperatures above 24°C can lead to restlessness.

Seasonal adjustments for optimal comfort and efficiency

Your heating needs will naturally change throughout the year. Adjusting your thermostat seasonally is crucial for both comfort and energy efficiency.

Winter warmth: balancing comfort and cost

During the colder winter months, maintaining a consistent temperature in your main living areas within the 18°C to 21°C range is key for health and comfort. However, you don't need to heat your home to the same level when you're out or asleep. Programmable thermostats or smart heating controls allow you to set lower temperatures for unoccupied periods, preventing energy waste. For instance, dropping the temperature to around 16°C overnight or when you're away can significantly reduce energy consumption without letting your home get too cold.

Spring and autumn: managing milder weather

In spring and autumn, when outdoor temperatures are milder, you might find you don't need your heating on constantly. Instead of a fixed schedule, consider using your heating to "top up" the warmth only when necessary. Many modern thermostats offer an "optimised start" function, which learns how long it takes to heat your home and only switches on the heating when needed to reach your target temperature by a specific time. This avoids overheating during milder periods.

Summer cooling: keeping your home comfortable

While UK homes are primarily designed for heating, summer can bring its own temperature challenges. Keeping your home comfortable in warmer weather often involves passive cooling strategies. This includes drawing curtains or blinds during the day to block direct sunlight, opening windows at night to allow cooler air to circulate, and using fans efficiently. If you have air conditioning, use it sparingly and set it to a reasonable temperature, typically not more than 5-7°C below the outside temperature, to avoid excessive energy use.

Specific temperature needs for vulnerable groups

While general recommendations serve most households, certain individuals require specific temperature considerations to protect their health.

Ideal temperatures for elderly people

Older adults are more susceptible to the effects of cold temperatures, which can exacerbate existing health conditions like respiratory or cardiovascular issues. For elderly people, living areas should ideally be kept at a minimum of 21°C. Bedrooms should be maintained at least at 18°C to ensure a safe and comfortable environment, particularly for those aged 65 and over. It's important to remember that 18°C is a minimum safe temperature, and many older individuals may prefer a slightly warmer environment for optimal comfort.

Ensuring comfort in a baby's room

Maintaining the correct temperature in a baby's room is crucial for their safety and well-being, as overheating is a risk factor for Sudden Infant Death Syndrome (SIDS). The Lullaby Trust and NHS recommend keeping a baby's room between 16°C and 20°C for comfortable and safe sleep. This range might feel cool to adults, but babies are less able to regulate their own temperature. Using a room thermometer can help you monitor the temperature accurately, and adjust your baby's clothing and bedding accordingly.

For safety and comfort, the Lullaby Trust and NHS recommend keeping a baby's room between 16°C and 20°C. Overheating is a risk factor for SIDS, so it's important to monitor the room temperature and adjust bedding and clothing as needed. This range may feel cool to adults, but it is optimal for infants.

Maximising energy efficiency through smart temperature management

Achieving optimal home temperatures doesn't have to mean excessive energy bills. Smart management can lead to significant savings.

The impact of small temperature changes

One of the most effective ways to reduce your heating costs is by making small adjustments to your thermostat. Reducing your thermostat by just 1°C can cut your heating bills by up to 10% annually. For a typical home, this could translate to a saving of around £90 to £120 a year. This saving occurs because your heating system runs for less time to reach a slightly lower target temperature, consuming less fuel.

Leveraging smart thermostats and controls

Smart thermostats and programmable heating controls are powerful tools for efficient temperature management. They allow you to:

  • Set schedules: Automate your heating to align with your daily routine, ensuring warmth when you need it and lower temperatures when you don't.
  • Zone heating: If you have a multi-zone system, you can heat different areas of your home to different temperatures, avoiding heating unused rooms.
  • Remote control: Adjust your heating from anywhere using a smartphone app, so you can turn it down if you unexpectedly stay out or warm your home before you arrive back.
  • Optimise performance: Some smart thermostats learn your home's heating patterns and the local weather, automatically making adjustments for optimal efficiency.

Beyond the thermostat: complementary energy-saving tips

While thermostat settings are crucial, they are part of a larger picture of home energy efficiency.

Insulation and draught-proofing

Even the most perfectly set thermostat can't compensate for a leaky home. Good insulation in your loft, walls, and floors prevents heat from escaping, meaning your heating system doesn't have to work as hard. Similarly, draught-proofing around windows, doors, and even letterboxes can eliminate cold spots and significantly improve comfort, allowing you to maintain a comfortable temperature with less energy.

Efficient heating system maintenance

Regular maintenance of your heating system ensures it operates at peak efficiency. An annual boiler service, for example, can identify and fix minor issues before they become costly problems, ensuring your system isn't wasting energy. Bleeding radiators and checking their pressure also helps them distribute heat effectively throughout your home.
