On the 15 June 2022 an update to the Building Regulations came into force supported by Approved Document F (Ventilation), volumes 1 and 2; Approved Document L (Conservation of Fuel and Power) volumes 1 and 2; Approved Document O (Overheating) and Approved Document S (Infrastructure for charging electric vehicles).

The period for the transitional arrangements for Approved Documents F, L, O and S in England ends on 15th June 2023 and any plots or sites that did not meet the transitional requirements will be subject to the new requirements of these Approved Documents.

Our FAQs have been updated to confirm the next steps for any plots (AD FLO) and/or sites (AD S) that did not commence prior to the cut off date.
