Average House Temperature in the UK Across Seasons and How to Maintain a Healthy Temperature

31 January 2024

In the UK, where weather patterns are varied, maintaining an ideal temperature within one’s home is both a challenge and a necessity. This article delves into the average house temperatures during different times of the year – Winter, Spring, Summer, and Autumn – while also exploring the ideal temperature settings and practical methods to maintain these temperatures.

Whether you feel your home is too cold or too warm, this guide is for you. Let’s get into what temperatures to expect at different times of the year and how to maintain a cozy home.

Average House Temperatures in the UK


During winter, when the outside temperature often plummets, the average indoor temperature in UK homes hovers around 18-20°C. This range is slightly lower than the global average, reflective of the UK’s cooler climate and often poorly insulated housing stock.


As spring heralds milder weather, homeowners tend to adjust their heating accordingly. The average house temperature in spring usually ranges between 17-19°C, providing a comfortable bridge between the cold of winter and the warmth of summer.


In the summer months, the UK experiences warmer weather, although rarely extreme. The average indoor temperature can rise to around 20-22°C, influenced by external temperatures. It’s not uncommon for homes to become uncomfortably warm during heatwaves, leading to the use of fans or air conditioning units where available and homes sometimes reaching temperatures of 25-30°C.


Autumn, with its gradual drop in temperature, sees average indoor temperatures of around 18-20°C. This is a transitional phase where heating usage increases progressively as the season advances.

Ideal House Temperatures

The ideal temperature for a home is somewhat subjective and can vary based on personal preference, health considerations, and the presence of vulnerable individuals like children or the elderly. However, a general guideline suggests maintaining around 18-21°C. This range is considered comfortable for most people and is the most energy efficient level when taking into account comfort and cost.

Methods to Maintain Ideal House Temperatures

Maintaining the ideal temperature in a home involves a combination of heating systems, insulation, and smart practices. Here are some effective methods:


Proper insulation is fundamental. Insulating loft spaces, cavity walls, and floors can significantly reduce heat loss, maintaining a more consistent indoor temperature and reducing heating costs.

Upgrading Windows and Doors

Double or triple-glazing windows and ensuring doors are well-sealed can prevent draughts and heat loss. This upgrade is particularly effective in older homes where single-glazed windows are common.

Smart Thermostats

Using smart thermostats enables homeowners to control heating more efficiently. These devices can be programmed to heat the home at specific times and temperatures, adapting to daily routines and reducing energy waste.

By setting the thermostat to the ideal temperature for you, it will help maintain your home at that temperature. With smart thermostats, this can also be controlled on a per-room basis, helping ensure the rooms that are cooler are heated, and those that are at the right temperature, are not. This helps save on energy costs.

Radiator Reflectors

Placing reflectors behind radiators, especially those on external walls, helps reflect heat back into the room, improving the efficiency of the heating system and lowering heat loss through the wall.

Draught Excluders

Simple solutions like draught excluders for doors and windows can make a noticeable difference in maintaining a consistent temperature and preventing cold air from entering the house.

Regular Maintenance of Heating Systems

Ensuring that boilers and central heating systems are regularly serviced and in good working order is crucial for efficient heating and energy conservation.

Consideration of Renewable Energy Sources

For an eco-friendlier approach, considering renewable energy sources like solar panels or biomass heating systems can be beneficial. While the initial investment can be significant, these sources can lead to long-term savings and reduced carbon footprint.

Understanding and maintaining the ideal house temperature in the UK is a balance of being aware of the average temperatures throughout the seasons and implementing effective measures to control indoor climate. By combining practical solutions like insulation, smart heating controls, and renewable energy sources, you can enjoy a comfortable, energy-efficient home year-round.
