## About this tender

The Building Regulations ensure a minimum safe standard for buildings. The Building Safety Regulator has responsibility for maintaining and updating the Approved Documents that accompany the Building Regulations. In December 2021, Part O was introduced to reduce overheating risks in new residential buildings, which can affect safety, health, and wellbeing. Most housebuilders now have experience applying Part O, making this a timely opportunity to review its implementation. This project aims to assess how effectively Part O compliant homes mitigate overheating risk and meet the functional requirements of O1(1)(a), O1(1)(b) and O1(2)(a). The project will also provide vital evidence to support a review of current overheating standards, helping us understand how homes built under Part O are used and experienced by occupants.
