Guidance on preventing overheating in the home

This guide, released by the Department of Energy & Climate Change (DECC) and the Adaptation and Resilience in a Changing Climate Coordination Network (ARCC network), outlines precautions people can take to prevent homes from overheating.


Energy efficiency improvements help make homes warm and cosy in the winter and keep energy bills down. They also help reduce carbon emissions and tackle climate change. Some energy efficiency improvements can also make homes hotter in the summer months. However, if these improvements are designed and installed correctly, the impact on summertime temperatures within homes can be greatly reduced. Future climate change is expected to increase outdoor temperatures and steps to adapt to a changing climate are essential. Undertaking energy efficiency improvements provides a great opportunity to not only make improvements to the standard of homes, but to also make them more resilient to climate change.


This document can help to identify the homes which may be most at risk of overheating and gives details of measures which, if implemented at the same time as energy efficiency improvements, can significantly reduce the risk of overheating, and the potential use of energy for cooling.
