Part O of the Building Regulations - Mitigation of Overheating in Dwellings CPD Webinar

CPD Synopsis: Part O of the Building Regulations - Mitigation of Overheating in Dwellings

Given the regular rainy and chilly conditions of the UK weather, it’s difficult to foresee a time when overheating in homes could be a serious problem in this country. However, the impacts of climate change are already being felt. The UK Met Office has one of the longest weather observation records in the world, beginning in 1884. Its latest State of the UK Climate Report, published in July 2025, shows that 2022 and 2023 were the warmest since records began.

Heatwaves are also becoming more frequent and intense, with 2018, 2019, 2021 and 2022 seeing new temperature records set. The summer of 2022 marked a milestone in UK weather history with 40ºC recorded for the first time in England and high temperature records set in Wales and Scotland. The UK Met Office predicts that in the next decade, we can expect UK summers to be hotter, with the increased likelihood of higher-than-average temperatures and with less rain.

These rising temperatures have significant implications for the UK. Extreme heat causes serious health issues for certain sections of the population, including the elderly, infants and those with chronic medical conditions such as asthma, heart problems and diabetes. Heat also impacts sleep patterns, as well as impairing mental function for a wider proportion of the population.

Part O of the Building Regulations was introduced in 2022 to tackle the growing challenge of overheating in new dwellings (it does not address existing buildings).

Delivered by our Product Specialists, the webinar outlines the requirements of Part O including relevant calculations and highlights some of the technology options that are available to help designers overcome the challenge of overheating in modern dwellings.
