The government has published five new Approved Documents under the Building Regulations for England which will come into force on 15 June 2022. Below is a brief overview and link to each new Approved Document. If we become aware of any specific implications of these regulations and their interactions with existing regulations, we will highlight these at a later date.

New Approved Document Part O
The aim of requirement O1 is to protect the health and welfare of occupants of the building by reducing the occurrence of high indoor temperatures. In the Secretary of State’s view, requirement O1 is met by designing and constructing the building to achieve both of the following:

  1. Limiting unwanted solar gains in summer.
  2. Providing an adequate means of removing excess heat from the indoor environment.
