- In a building or controlled service or fitting not complying with a relevant requirement where previously it did; or
- In a building or controlled service or fitting which before the work commenced did not comply with a relevant requirement, being more unsatisfactory in relation to such a requirement.
Where a 'relevant requirement' is any of the following applicable requirements of Schedule 1, namely:
- Part A (structure).
- paragraph B1 (means of warning and escape).
- paragraph B3 (internal fire spread—structure).
- paragraph B4 (external fire spread).
