There are multiple versions of this provision on screen. These apply to different geographical extents.
The term provision is used to describe a definable element in a piece of legislation that has legislative effect – such as a Part, Chapter or section.
Sometimes the text of a provision is changed, but the change(s) only apply to a particular geographical area. In some limited cases where this happens, the editorial team create a version for each different geographical area. Multiple versions are only created in this way where the change in question is a substitution so that there are different versions of the text for the different extents. Insertions and repeals of text do not give rise to such multiple versions.
The Building Regulations 2010, Section 25 is up to date with all changes known to be in force on or before 03 September 2024. There are changes that may be brought into force at a future date. Changes that have been made appear in the content and are referenced with annotations.
Revised legislation carried on this site may not be fully up to date. Changes and effects are recorded by our editorial team in lists which can be found in the ‘Changes to Legislation’ area. Where those effects have yet to be applied to the text of the legislation by the editorial team they are also listed alongside the legislation in the affected provisions. Use the ‘more’ link to open the changes and effects relevant to the provision you are viewing.
